The Advantages and Disadvantages of Non- Destructive Testing

What Is Non-destructive Testing? 

Non-destructive testing (NDT) also known as ‘positive testing’.

As its name implies, non-destructive testing means testing of materials without destroying them.

It is a kind of a testing approach in which the testing is performed to cover only the positive cases to confirm that the software behaves properly and returns the expected results as per the product requirement. It is one of the best courses to do if you want to get a high profile job in abroad or India in oil & gas, petroleum, aircraft, refinery, etc. It is commonly used in the area of aerospace engineering, mechanical engineering, civil engineering, electrical engineering, system engineering, and medicines.

5 Benefits of Steel Testing

Steel Test refers to the test which begins with the help of a diamond pyramid. The diamond pyramid is pressed into the steel at a pre-specified load. This diamond pyramid measures the hardness and the level of hardness steel gets verified. This verified steel is used for different purposes.

Tensile tests can be done at different temperatures because of brittleness increases as temperature fall. There are many other tests that can be used to check steel's material property, such as wear test for nails, drivability test for wire and bending test for the wire.

Tensile tests provide better information about the test material and thus help keep up the material quality. They also help with the development of new materials. These tests provide information about the mechanical properties of the material. The results of the tests help the material suppliers understand the material quality. The results also help with certification purposes.

Steel Tensile Test

Tensile Test is performed on mild steel and high tensile steel to determine it's different properties. In a tensile test, a steel rod is messed to tension load by the means of UTM. A steel tensile test is done in a steel tensile laboratory. There are many steel tensile services that are done in different industries like in the automobile industry steel is used in different vehicles.

5 Benefits of Steel Testing

The manufacturing industry is one with extremely high demands, including peak efficiency from machines and equipment. Tensile Testing provides data on the integrity and safety of materials, components, and products. There are many different types of tensile testing like adhesion/bond strength, peel, tear-resistance, and crimp-joint pull-off the force.

Tensile testing enables the manufacturers to ensure that their finished products are ready for use and are of good quality.

Some of the benefits of Tensile Testing are: -

Ensure Quality products are delivered.

The first and foremost benefit of tensile testing is ensuring that a quality product is delivered to customers. Tensile Testing ensures that any material must meet some quality standards so that there might not be any future consequences regarding the quality of the product.

Opportunity to identify alloys and their applications.

Another important benefit of tensile testing is getting the opportunity to identify new alloys and find out their different applications. Tensile Testing can help manufacturers to know which qualities metals have. This test can help manufacturers to look out for improved materials.

Reduce Material Costs.

Tensile Testing can help in reducing material costs as the manufacturer knows which metal is best and which is worst. So, he doesn't have to check the quality of each and every material, these qualities are already checked and verified using this test. So, this test can be cost-cutter for any industry.

Meet International and Industry Standards.

Tensile Test works on international and industry standards. So, if any metal is verified then the international and industry standards are already met.

Checking Metal Strength.

The material strength obtained by tensile tests has important application value for design and material selection, development of new material, safety, and evaluation of equipment, and all these things are directly based on the results of tensile tests.

These are some of the benefits that are availed by this steel tensile test and can help any manufacturer to be benefited easily.

Benefits of Automotive Testing Services

Automotive Testing Services puts full vehicles, systems, and components through a series of laboratories. With virtual and real-world assessments, automotive services ensure it is safe, reliable, and compliant with safety regulations. The automotive testing system is the requirement for accessing the global automotive market and manufacturers must show they have put their product through a rigorous assessment. 

Automotive testing covers a wide range of vehicle features. Some of the features are to buzz, squeak and rattle tests, crash simulations, and extensive automotive electronics testing.

Benefits of Automotive Testing

  1. Reusability- The scripts used in automotive testing are reusable.  We do not need new scripts all the time, even if the version of the OS on the device changes. The automotive testing laboratory allows us to redo the exact same test, without leaving any steps.
  2. Bugs- Automotive testing services help in finding bugs in the early stages of software development, reducing expenses, and working hours to fix these problems as well.
  3. Reliability- Automotive Testing is more reliable and much quicker when running boring repetitive standardized tests that cannot be skipped. However, the automotive testing system may cause errors when manually tested.
  4. Simultaneity- We can test more devices simultaneously resulting in comparative detailed reports generated in less time with the exact same parameters. This is because the exact same scripts were run.
  5. Continuity- It helps testers, such as automation engineers. However, they can see exactly what other engineers have done, what scripts he has already written, etc.
  6. Additional methods- One of these methods is the stress test in which the capacities of the application and operational infrastructure will be tested to limit with stress, this cannot be done manually.
  7. Volume- Automotive testing allows running tests on thousands of mobile devices. Testing all of them may be impossible.
  8. ROI- This may hold back for many. However, it is proven that the return of the investment is long-term and will also save time.
  9. Running Tests 24/7- No matter where we are in the world. We can start tests when we leave the office and we can see the result.
  10. Fewer human resources- We do not need many people. We can test automation engineers to write your scripts to automate your tests.  Unlikely many people doing boring manual tests repeatedly. 

Why Automotive Testing Is Important?

Working for multi-year development automotive development, timeframes and suppliers will need to test and validate across the full life cycle. The problems faced by the industry include the increase of complexity, long test cycles. Below are the key trends and importance of the automotive testing system.

Automotive Testing services offer various benefits, including:

  • Regulatory compliance- Global market access requires automotive component testing and relevant global regulations to ensure overall safety.
  • Early discovery of faults- Automotive component testing helps to discover the faults in the development phase. Therefore, this avoids expensive product recalls and saves you money.
  • Boost brand reputation- testing your product can iron out faults and this will enhance the reputation as a provider of quality vehicles.


In the end, we will have better quality software, which will be released earlier. With fewer problems and fewer resources used. 

However, there is usually always a downside to everything. Therefore, there are downsides to automotive testing as well.

 There are a few disadvantages of automotive testing: 

The automotive testing system will not fix the specific problems that users may have. Whenever there are, writing and testing of the scripts there are just some scenarios that are being tested, not all of them. The main purpose of automotive testing is to find bugs in simple operations.

For example- Login into the app; create a new account; send an email when the password is forgotten. This is what the testing does. 

Some of the automotive industry testings are vibration testing, climatic testing, and mechanical testing.

  1. Vibration testing- Vibration and shock might have profound effects on a vehicle’s long-term performance and reliability. This type of testing requires powerful tools.
  2. Climatic testing- The average of the vehicle is exposed to a diverse set of environmental conditions over the course of its life. This type of test is done to check how vehicles are going to perform to extreme temperatures, humidity, and other conditions.
  3. Mechanical testing- Mechanical testing is used for automotive engines and other components.

PPE Suppliers Are Providing Inauthentic Certificates to Buyers, Here Is How You Can Verify Them.

COVID-19 has led to an increase in the demand for personal protective equipment (PPEs) in the country. This has led to the provision of inauthentic and fraudulent certificates provided by PPE suppliers to purchasers, including government procurement agencies.

According to accrediting agencies and market sources, this course of action has put the frontline healthcare workers’ lives at risk.

The Indian market is full of private certification bodies which issue fake certificates to industries. It is difficult yet important to distinguish an authentic certificate from the inauthentic and fake ones.

‘The quality of PPE is at Centre stage now. The union health ministry has also specified standards and reports acceptable from national and international organizations and labs which has led to all kinds of certificates in the market, most of them inauthentic and some may even be fraudulent,’ says Anil Jauhri, former CEO, National Accreditation Board for Certification Bodies (NABCB).

How can we verify an authentic certificate?

There are certificates for CE mark and ISO standards. While notified bodies (NB) of European Commission (EC) can only issue CE certificates, ISO certificates are those which come from duly accredited CBs and carry the logo of the accreditation body (AB) under the prevailing international system.

As Mr Jauhri conveyed, ISO is only a standard-setting body and does not undertake any certification. Hence, the use of an ISO logo in any form on a certificate is a misuse and shows inauthenticity.

In India, certification bodies should be accredited by NABCB for undertaking certification as per ISO 13485, an international standard for quality management systems (QMS) in medical devices, also accepted by many regulators around the world.

NABCB under Quality Council of India (QCI) is the national accreditation body in India. Any certificate bearing NABCB logo should be acceptable because it indicates the issuing of a certificate by a competent and recognized body.

‘It may also be noted that the CE mark is Europe’s regulatory mark and in case of PPEs, EC has a separate regulation under which Notified Bodies are designated only in Europe. There may be some branches or associates of NBs in India, but any certificate must be from the NB listed in the European Commission database,’ he further informed.

Click here to view the list of Notified bodies under EC.

The total projected demand of PPE kits till June 2020 stands at an estimate of Rs. 2.01 crore. Around 107 PPE manufacturers have raised their daily production to about 1.87 lakh PPE kits.

As per norms, an authentic certificate should contain:

Name and address of the organization certified

Scope of certification describing its activities like production, packing and sale of PPEs like coveralls, shoe covers and more

Standard (or sometimes scheme or regulation) against which certification is granted like ISO 9001 or ISO 13485 (standard)

Date of issue and expiry of the certificate

Unique identification number of the certificate

Name and address of the CB

Logo of the CB

Accreditation a symbol indicating the name of the accreditation body (AB)

How do you verify a certificate in exceptional circumstances?

In most countries, with the absence of a law requiring Certification Bodies to register, accreditation is the only way to recognize a competent and authentic certificate.

The International Accreditation Forum Mark (IAF) is an optional standard which shows the certificate is covered under the Multilateral Mutual Recognition Arrangement (MLA) of the IAF, hence, making it internationally equivalent and acceptable in the market.

Further, to judge the authenticity, one can see the names of member Accreditation Bodies of IAF on its website which also gives information on which accreditation bodies are signatories to IAF.

Once the user locates the AB in a country, he/she can visit the AB and IAF website to verify if it accredits the Certification Body. Here on, they can verify the certificate because as per international norms, CBs must help verify certificates issued by them.

The pandemic has led to a rise in these fraudulent certifications by unregistered Certification bodies. The current scenario mandates the verification of these certificates to ensure authenticity. One can undertake these measures to distinguish verified suppliers and work with them.

ANSI Standards-What are They?

The American National Standards Institute (ANSI) is a private, non-profit agency that promotes and enhances the domestic and foreign effects of the U.S. universal norms and compliance appraisal framework.

Nationally or internationally, ANSI aims to enhance global competitiveness and quality of life of US companies by offering a basis for and safeguarding their reputation in the production of equal expectations and compliance measurement systems. The Institute encompasses almost all sectors and serves the diverse desires of over 270,000 businesses and associations, as well as 30 million people worldwide.

History of ANSI:

ANSI is a non-profit, corporate association, funded by a broad variety of private and public sector organizations, established in 1918 by five engineering societies and three governments. About 1400 businesses, organizations, departments, administrative and external participants are covered by ANSI. The mission of ANSI is to support the US economy to stay successful on the global market and to maintain health and protection for customers by maintaining the sustainability of the community. All sectors, from the farms to manufacturing, are protected by ANSI requirements and guidelines.

National Standard Activity:

Ask most people regarding ANSI and the chances of learning regarding standards growth are high. We are all referring to 'ANSI guidelines,' which lets us think that ANSI is currently evolving norms. Nonetheless, ANSI accredits several various creators, including electrical technology associates such as NFPA, UL, and IEEE. The developer calls their final Standard an American National Standard (ANS) by being an approved developer and adopting the procedures established by ANSI.

Developers aren't carelessly authorized. A collection of normal programming protocols for ANSI must be sent for each developer wishing to be approved as ANSI.

Such processes shall conform to the core values of transparency, consent and fair process of ANSI. The system must also be checked at least once every five years with its policies and processes. The audit aims to confirm conformity with the accreditation standards and to check that developers' processes and procedures continue to conform to their approved procedures and current ANSI specifications.

Why is it necessary to determine an American National Standard?

It is the framework holding the set of norms focused in the private sector. We are likely to see more regulatory influence over a uniform program and less acceptability around the country without a mechanism like the one given by ANSI. Organizations of competency (inspectors, building departments, etc.), federal and municipal entities and customers define and enforce requirements that are known as ANS. Departments have authority. Through the usage of established guidelines, they will guarantee that the norm has been implemented into a transparent framework of consent so that those impacted by the norm have sufficient opportunities to engage so respond.

Standards are usually released as ANS in three ways: committee, association and canvass.

  • ASC method (Accredited Standards Committee):

The approaches used by developers who choose to establish an approved professional group to carry out the specific research are the Accredited Standards Committee. The National Code of Electric Protection is established for instance by ASC C2. The technology support agency is IEEE which oversees the C2 committee's mechanism which activities.

  • Organization method:

Organizations who want to create a series of approaches tailored to their operational requirements use the operational approach. The methods still conform with but are usually more detailed, the ANSI protocol and the recommendations. For examples, in the sense of ANSI, the NFPA establishes the National Electrical Code.

  • Canvass method:

Abroad variety of developers use the development of the Canvass Method of specifications. The ANSI processes define several specific criteria for this system. Through this process, a panorama list is drawn up of concerned parties and this body checks the existing norm. This approach is used by UL, NEMA, ARI, and several others.


In short, in the US uniform framework, the function of ANSI is irreplaceable. The position ANSI played and helped by active involvement in the standard method and in the future decision of the path that ANSI follows must be understood by any person in the electrical industry, including auditor, contractor, supplier, builder, etc.

Standards Behaviour is one of the major ANSI publications. This is created twice a week which demonstrates which criteria are now being implemented which established for public inspection. Action Specifications on the ANSI platform are eligible. For those interested with the US codes and standards program, ANSI’s official website might help you.

Why is Nutritional Analysis Important?

Food is the fuel the body needs to replenish itself with. Each civilization has given profound importance to food type and consumption pattern.

Hence, it can be easily assumed that food has the power to influence the bodily metabolism and organ health directly. After ingestion, food is digested through our gut with the help of various digestive juices and ends in being absorbed in bloodstreams as different types of biomolecules which are known as Nutrients.

If food is the reason, Nutrition is the result. We consume food so that we can obtain proper nutrition.

Nutrition is the process by which important beneficial biomolecules or Nutrients, after reaching their destination within the body positively helps in functioning, maintaining or improving important bio metabolisms like building muscles, producing energy, thriving body cells, improving body health, replenish malnourishment, and strengthening immunity.

Theses Nutrients are of two types. 1. Macronutrients 2. Micronutrients. The next chart is an overall idea about the different types of nutrients and their functions.


Bodily Function


Energy production


Muscle Development and Cell Proliferation


Energy production, storage energy



Bodily Function


Hormone production, Hormonal balance maintenance, Bone development and density maintenance, Eyesight development and maintenance, Reproductive organ health maintenance, Immunity boosting etc.


Electrolyte equilibrium maintenance, Helping in energy production, Muscle work, Brain development, Nervous functions etc.


Now that we have understood the importance of food, nutrition and nutrients, and their major functions in our body, let us further focus the lights onto the matter about what is the Nutritional Analysis and why it is of such utmost importance.

Nutritional The analysis is the scientifically set stepwise process of assessing the types, amount and nature of nutrients available in a given food sample. In India, Nutritional Analysis Methods are standardized and set by FSSAI.

The importance of nutritional analysis has several spectrums. There are as follows:

Food components:

 Food Nutrition Analysis helps in the detailed and perfect determination of the     component nutrients present in any food item.

  • Food components have vast bio metabolic roles and could affect human health severely.
  • If the consumer has a clear idea about the food component, he or she may choose or reject specific food items according to his or her health condition.
  • As an example, khichdi is more beneficial than plain rice or roti alone in case a person is looking for low-cost supplementary food for protein-energy malnutrition. The combined protein sourced from rice and dal makes khichdi more nutritional and wholesome.
  • Nutritional Analysis and comparison of ‘Khichdi’ with various other food items helped scientists in concluding this revolutionary easy way which is now an instrumental supplementary therapeutic dish in India’s master plan of fighting Protein Energy Malnutrition.

Nutritional value:

  • Nutritional Analysis detects the exact nutritional value of any given food items.
  • It determines the percentage of macro and micronutrients present in that food item as well as presence of inhibitors, toxic chemicals or any other new component.
  • It is also important in nutrition mapping where a variety of food items are regularly being tested and included in the standardized book of Nutritive Value of Indian Foods by Indian Council of Medical Research.
  • Presences of inhibitors, toxic chemicals in various foods are tested in food nutrition analysis. Inhibitors like phytate, oxalate decrease the bioavailability of nutrients and toxic chemicals like saponin, trypsin inhibitors, pathogens etc. cause mild to severe ailments in the human body.
  • Food Nutrition Analysis by FSSAI has been instrumental in India’s nutrition mapping as there are vast varieties, numbers and types of crops, fruits and vegetables, fishes available throughout different part of India.

Why Msme Should Hire Professional Testing Laboratory for Testing Activities?

For every Businessman, their business is like their baby which makes it hard to compromise with any business aspect. To grow to hire right staff members is not enough, you need to come in contact with right contractors that can help you to work and focus on those things which neither you nor your staff members are efficient enough to do to make your business thrive. So, one can say business outsourcing for small and medium business has a lot of benefits.

What is Outsourcing Manufacturing?

Outsource refers to the hiring of people from the outside of the enterprise to assemble, built our the entire product. The main reason why companies choose outsourcing is to reduce its overall cost, labour is among the top factor in terms of cost.

Outsourcing in production companies to third parties leads to a great amount of decrease in production costs, which leads it to be more affordable that can have a comparative advantage than in-house production.

Most of the times outsourcing provide a great benefit to utilize assets which are already there without investing in any additional fixed and variable costs.


When and What to Outsource?

So, the question arises when you need to do outsourcing? The answer to this is quite simple, you must evaluate the goals of your business, things only you can achieve? and things only you can provide to your customers? Things which can be done with outsourcing? So, for all these you need to ask some questions:

  • Is there a need to deduct a certain fixed cost to optimize the budget of the company?
  • Are there some tasks that need your business to operate which require certain skills and expertise that your staff does not have?
  • Are there some basic tasks which are making your staff to divert their focus on main and important tasks?

Benefits of Outsourcing Manufacturing

  • Lower Labour Costs

Low labour costs are the main benefit of outsourcing, while there are many implications, performing outsourcing at the right time and place is the most essential and viable option. Labour cost which can be reduced to so much if you come in contact with the right outsourcing partners, it is confirmed by various enterprises that achieve high level of savings and are able to focus on main tasks when they chose outsourcing options.

  •  Overhead Cost

Various companies outsource their work to eliminate overhead costs which are associated with business operations facility. Overhead costs include production equipment and utilities. There are other costs also like indirect costs, technicians, material handlers, shipping personnel etc.

  •  Focus

For a company to grow it is important that they focus on core competencies which are things that they are best at whether it is sales, marketing or production and leave the general or non- core competencies to the third party to handle so that business can focus and grow. There may be a certain situation arises that there is sometimes an increase in demand and you need additional resources to meet the deadline as lack of it can affect the business so outsourcing companies can help them to fulfil demands in this way, you will grow thus maintaining its goodwill.

  •  Fortress Nutrition

There are a lot of companies that help in food and nutrition services. From research development to manufacturing and packaging, they partner with small and medium clients to fulfil their demands and needs. They also provide unrivalled skills and expertise in all the aspects the business needs, whether it is packaging, blending, food testing or quality control.

Why MSME's are preferring outsourcing for testing?

Increase in regulation is mainly impacting the decision of a small business to shift from in house testing because they are  on small scale and don’t have enough resources which can increase their overall cost so that is why they prefer third-party labs for testing and it is more cost effective and at the same time they can focus on other important things.

Small and medium enterprises don’t always have resources like volume, knowledge, micro testers to perform pathogen or allergen testing in-house as well as they may send testing to focus on what they do best like food production and not o0n which they lack or they may want to keep them outside of litigious circumstances, apparently, the industry wants to do what is right for them but want to spend limited so that is why they outsource to get work done in the most cost-effective way. Small and medium companies are outsourcing their testing, third party labs are getting immense popularity in allergen and pathogen testing.

An area in which outsourcing is growing in terms of food:

Lab Accreditation

National Accreditation Board for Testing and Calibration Laboratories (NABL) is a quality control board of India, they are established with an objective to provide industries to collaborate with third-party for quality and technical check and test in laboratories.

So to achieve this NABL provides laboratory accreditation to perform tests in labs in accordance with ISO 17025:2005 medical labs. These services are provided in non- discriminatory manner and are accessible to all labs abroad as well in India regardless of status, ownership, size, and independence.

 ISO17025 accreditation is driven by customers standards and rules as sometimes customers specify some rules which require customised models which should be done in ISO certified lab to ensure the quality of the food system and the integrity of its lab test results...

While specifications are not listed on the import testing in accredited labs, implications are to follow ISO 17025, its a requirement has heightened the interest in accreditation.


So, from the above, we can conclude that outsourcing industries have a lot of scope in terms of lab testing because of it is better, cost-effective and experts work on it.

Protective Clothing Testing Lab in India

The Indian Board of Medical Research (ICMR) licensed private diagnostic laboratories for carrying out COVID-19 tests find it difficult to procure appropriate personal security equipment for their collection workers, namely, cover-all. The laboratories hope that the Centre's push to increase the availability of essential life-saving equipment, including PPE, may accelerate the manufacture and supply of such items. 

Leading ICMR players said that their facility is ready, personnel is qualified, but adequate diagnostic trials of the companies that can supply them and PPEs from the open market are yet to be received. In addition, they have been able to provide sufficient quantities of test kits. Thanks to lock-down and freight flow interruptions, it is often challenging to import test kits.

The Indian Council of Medical Research (ICMR) has proposed hydroxychloroquine to be used as a preventative against the disease by health care staff and treatment professionals of reported patients of COVID-19, even though experts have claimed that this medication is not successful in the prevention of COVID-19. Hospitals, including protection like masks and bodysuits, are often considered to be effective in ensuring protection for health personnel, according to researchers, but lacks protective gear.

How can Protective masks be beneficial?

Droplet transmission happens when a human has near contact (within 1 m) with a person with respiratory symptoms (for instance, coughing or sneezing) and is, thus, at risk of exposure to potentially contagious respiratory droplets with mucosa (mouth and nose) or conjunctiva (eyes). Therefore COVID-19 can be transmitted through direct interaction with infected individuals and indirect contact with surfaces in immediately surrounding areas and items in use on an infected individual (e.g. stethoscope or thermometer). Dissemination may also occur by fomites in the immediate atmosphere around the infected person. Therefore, protective clothing is the most essential elements one will require during this tough time where the entire nation is suffering.

Significance of protective clothing for the medical staffs:

The first to react when an infectious pathogen affects a population is health workers. In reality, they are also the first ones to be impacted — the first indication that an odd event happened is a series of cases of severe illness in health staff. Health employees could have a greater chance of infection before the origin of an epidemic is established and so infectious prevention steps may be implemented. Health staffs are at an elevated risk of infection owing to the frequent and long-lasting interaction with patients with a heavy viral load.

People across Asia have been encouraging wearing face masks to prevent COVID-19. Many countries still debate how to introduce the procedure to reduce the transmission of the disease owing to the COVID-19 crisis. Germany has become one of those countries and its Federal Institutes of Pharmaceuticals and Medical Devices has released details on standards of safety provided by different masks.

Where you can find such protective clothing?

How Carbs Affect Blood Sugar? Glycemic Index

People who are diabetics often deal with problems related to diet because they want to maintain their blood sugar level. Studies have shown that carbohydrates release more sugar level in blood than protein and fat. However, one cannot escape the consumption of carbohydrates as it is present in our day to day meal. But how carbs affect blood sugar when it enters our body? You can find your answer here. 

What are Carbohydrates? 

Before understanding the effects, we need to know what exactly are carbohydrates and how it is classified. Carbs are the essential food group which is often found in the form of starch, sugar or fibre in different food items such as fruits, milk, vegetables, cereal and grains. 

Initially, it was classified as simple (composed of sugar with simple chemical structure) and complex (composed of sugar with complex chemical structure). Later, it was difficult to determine its effects on blood for which the Glycemic Index was determined. Glycemic Index is a ranking between 0-100 assigned to food according to their effects on the blood glucose level. Food with the high glycemic index, such as white bread, cause a rapid change to the blood sugar, whereas, food with a low glycemic index, like whole oats, results in slow changes.

Factors affecting the glycemic index of food

  • Even though carbs are naturally present in the food items, still there are some factors which can affect its glycemic index. Here is a list of such factors.
  • The content of fibre- people prefer high-fibre food because it usually digests slowly leading to a low rise of sugar level.
  • Processing of food- the refining and milling is done to remove germs from the grains but raises the level of the glycemic index.
  • Ripening- unripped fruits and veggies often contain a lower glycemic index than ripped ones. 
  • Fat and acid content- food containing fat and acid is translated into sugar steadily. 
  • The physical form of food- It is normally said that the whole form of food is better than processed ones. This is because coarsely ground grains digest gradually as compared to fine grounds.

How carbs effects sugar level?

As carbohydrates enter our body, it is broken down into smaller pieces which turn into sugar. Pancreas, located behind the stomach, stands responsible to produce insulin which further transfers sugar from the blood to cells to consume it as energy. The person with diabetes often has a pancreas that produces insufficient insulin or the insulin produced is being used inefficiently. When food with refined carbohydrates is consumed, the particles are broken with speed resulting in loads of glucose in the blood. This burdens pancreas to produce enough insulin. Eventually, the pancreas becomes unable to stand the load of glucose which increases the level of sugar in the blood. This scenario often takes place with simple carbohydrates which is why consuming complex carbs is beneficial as they produce glucose slowly. 

Wrapping up

So, next time you eat something, do check its carbohydrate content to stay healthy as a little fluctuation in carbs can fluctuate sugar level in blood.
