Here Is How Fruits, Vegetables And Legumes Prevent The Onset Of Type 1 Diabetes According to Science

type 1 diabetes plant-based diet

Type 1 diabetes has been shown to be prevented by eating a so-called 'medicinal high fiber diet' of fruits, vegetables and legumes, according to recent research. If you fear you are a candidate for type 1 diabetes this study can help guide you to make the correct food choices to prevent the disease.


It seems that when all goes right with our health, it’s blamed on the gut. Conversely, when something goes wrong with our health it’s also blamed on the gut. The gut, while it has much to do with good overall health, has been shown in a recent study to be central to preventing type 1 diabetes when interacting with a high fiber, low fat, high quality carbohydrate diet loaded with fruits and vegetables.

Can type 1 diabetes be prevented? A new and somewhat validating study published in the journal Nature hints that type 1 diabetes can be prevented by eating a high fiber, high carbohydrate anti-viral plant-based diet.

“Our research found that eating a diet which encourages the gut bacteria that produce high levels of acetate or butyrate improves the integrity of the gut lining, which reduces pro-inflammatory factors and promote immune tolerance,” said Eliana Marino researcher at Monash University in Australia. “We found this had an enormous impact on the development of Type 1 diabetes,” Marino added.

This process of fermentation in the gut, according to science, produces acetate and butyrate which, when combined, are hailed as protecting against Type 1 diabetes, according to this latest research. That being said, it should be known that the foods with the highest amount of fiber that create these high levels of acetate or butyrate are none other than plant-based foods such as fruits, vegetables and legumes.

The science highlights how diet and non-pharmaceutical approaches, as well as gut bacteria, prevent and may even reverse so-called “autoimmune diseases” such as Type 1 diabetes.

Eating a plant-based diet, namely a diet high in fiber from fruits and vegetables, such as leafy greens, oranges, apples, kiwi, green beans, and legumes, increase the plasma butyrate content because of their increased fiber content. Fruit also provides several vitamins and minerals and are one of the best and most healthy sources of butyrate that boost gut health, as well as overall health.

The findings also showed that the Standard American Diet, which is highly processed and refined and low in dietary fiber by definition negatively affects human gut microbiota and the production of short-chain fatty acids acetate or butyrate.

Can Type 1 Diabetes Be Prevented? This Is Huge!

What is perhaps more validating and relevant in this study is that the science shows the mice that were housed under specific-pathogen-free conditions were completely protected from diabetes, but those housed under germ-free conditions were not. This cements the idea that type 1 diabetes is likely triggered by a virus and is likely not genetic, as once believed.

What is more, foods such as fruits and vegetables that are high in plant-based fiber and thus, acetate and butyrate, are also largely antiviral. Therefore, a diet high in these foods creates a preventative barrier against viral conditions that may cause the onset of type 1 diabetes.

Plant-based Diets Do Prevent Disease

Regardless of the underlying cause of type 1 diabetes in humans, the application of a large amount of acetate and/or butyrate (fruits and vegetables) was found to be an effective intervention.

The study confirmed that what they called a “medicinal food approach” might be particularly relevant for type 1 diabetic, “as this disease usually arises in children and young adults, for whom drug-safety considerations are paramount and detection of autoantibodies allows intervention before the onset of clinical diabetes.”

The study indirectly highlights the prospects of so-called medicinal foods, or ‘nutraceuticals’, i.e, high amounts of fruits and vegetables for the treatment of all human disease.

What’s highly validating about this study is that it gives credit to the plant-based diet for promoting health and preventing disease. To break it down for you, the study confirms eating a high amount of plant-based foods such as fruits, vegetables, legumes and even nuts and seeds, promote and strengthen gut health, are highly anti-viral and prevents both type 1 and type 2 diabetes.

So, can type 1 diabetes be prevented? According to both science and nature, the answer would be a resounding yes!
