Understand The Relation Between Ultra Processed Food And Diabetes


Diabetes has become one of the most prevalent health conditions globally, with over 460 million people living with diabetes worldwide. While genetics plays a role, diet and lifestyle factors significantly impact one’s risk of developing diabetes.

In particular, the consumption of ultra-processed foods has been linked to an increased risk of diabetes. This article will examine what ultra-processed foods are, why they may be problematic for diabetics, tips for limiting ultra-processed foods, and the key takeaways.

Understanding Ultra-Processed Foods

Ultra-processed foods are industrial formulations created from substances derived from whole foods such as oils, fats, sugars, starch, and proteins. They go through multiple processes, such as hydrogenation, hydrolysis, and extruding.

Ultra Processed Food And Diabetes

Examples of ultra-processed foods include mass-produced breads, desserts, ready meals, processed meats, and snacks like chips, candies, and microwaveable meals.

What makes these foods concerning is that they are designed to be convenient, hyper-palatable, and affordable. They often contain high amounts of added sugars, saturated fats, sodium, and chemical additives while lacking beneficial nutrients.

Frequent consumption of ultra-processed foods has been associated with higher risks of obesity, heart disease, high blood pressure, and diabetes.

Why Ultra-Processed Foods Are Bad For Diabetics?

There are a few key reasons why a diet high in ultra-processed foods can be harmful for those with diabetes or at risk of developing it:

  • Spikes in Blood Sugar: Many ultra-processed foods have a high glycemic index, meaning they cause rapid spikes in blood sugar. This puts extra strain on the pancreas and can contribute to insulin resistance over time.
  • Weight Gain: The hyper-palatable nature of processed foods can easily lead to overeating and excess calories. The resulting weight gain increases insulin resistance and diabetes risk.
  • Lack of Fiber and Nutrients: refining grains strips out beneficial fiber. The lack of vitamins, minerals, and antioxidants common in ultra-processed foods can negatively impact metabolic health.
  • Chemical Additives: Additives like artificial sweeteners, colors, flavors, and preservatives may have negative health effects. For instance, some research links artificial sweeteners to glucose intolerance.
  • Inflammation: Diets high in ultra-processed foods cause inflammation in the body, which is implicated in the development of diabetes. The high omega-6 content and lack of antioxidant nutrients contribute to this.

Overall, swapping ultra-processed convenience foods for whole, minimally processed alternatives helps manage blood sugar and weight and reduces diabetes risk.

How To Limit Ultra-Processed Foods?

Here are some practical tips for reducing your intake of ultra-processed foods:

  • meal plan around whole foods like fruits, vegetables, legumes, lean proteins, whole grains, nuts, and healthy fats.
  • Limit ready-to-eat frozen meals, fast food, pre-packaged snacks, fruit juices, candies, cookies, sweetened cereals, and desserts.
  • Read ingredient labels and avoid products with long lists of unrecognizable ingredients. Stick to real, whole-food ingredients.
  • Shop the perimeter of the grocery store where whole foods like produce and proteins are located. Avoid aisles filled with packaged snacks.
  • Cook at home as much as possible so you can control what goes into your meals.
  • Watch out for marketing buzzwords like “healthy” or “natural,” which can mislead consumers about nutrition facts.
  • Focus on adding more vegetables, pulses, and fruits. They provide antioxidants, fiber, and nutrients beneficial for blood sugar regulation.
  • Be cautious of swap alternatives like low-fat or gluten-free, as they often add more sugar and salt to make up for flavor.

With a little meal planning, label reading, and kitchen time, limiting ultra-processed foods is very doable. Small steps to eat more real, whole foods each day positively impact diabetes management.


In conclusion, the rise in consumption of ultra-processed foods parallels the increasing rates of diabetes worldwide. The additive-laden, low-nutrient, hyper-palatable nature of these industrial formulations promotes weight gain, fat accumulation, and inflammation—all risk factors for diabetes.

Limiting the intake of ultra-processed foods in favor of whole, fiber-rich plant foods and lean proteins helps manage blood sugar and reduces the risk of diabetes complications. With sound nutrition choices and meal planning, those living with diabetes or at risk can better control their health.


Q: Are all processed foods bad?

A: Not necessarily. Minimally processed foods like canned fish, frozen fruits and vegetables, and some cheeses can still be part of a healthy diet. The concern lies more with “ultra-processed” foods designed to be convenient and hyper-palatable.

Q: Can diabetics ever eat sweets?

A: Occasional sweets as part of an overall healthy diet may be fine for some diabetics. Focus on controlling portion sizes and balancing sweets with more nutritious choices. Always consult your doctor.

Q: What about sweeteners and sugar substitutes?

Artificial sweeteners are controversial but may be a lesser evil compared to sugar for diabetics. That said, overuse can encourage sweet cravings. Moderation is key.

Q: Are whole-grain breads and cereals okay?

100% whole-grain options without added sugars are better choices. But limit quantity, as grains still impact blood sugar. Emphasize vegetables over grains.

Q: What about fruit and fruit juices?

Whole fruits are encouraged. But juices concentrate sugars without fiber benefits. Eat fruits whole, or limit juice portions.
