Dear Rohan, Thank you so much for sharing your concerns with us, yes of course the vast majority of diabetes can be prevented through healthy diet and lifestyle changes. Organic food will be a healthier choice, so choose organic or fresh produce instead of these other choices that is not good for your health. It is good to know that fruits and vegetables may prevent many illnesses including diabetes. Dietary recommendations to prevent diabetes and even reverse it are: Decrease intake of added sugars and processed foods, Swap out refined grains for whole grains, Increase fiber intake, Increase fruits and vegetables intake, Eat less meat, and avoid processed red meat, Eat healthier fats. So try to stick to this one helpful tool which shows you what your daily food intake should look like: half fruits and vegetables, about a quarter of whole grains, and a quarter of healthy proteins (plant protein is ideal here), with some healthy fats and no-sugar-added beverages.
