In reading an article about whether a plant-based diet can reverse cardiovascular disease, it was said there have not been large enough studies on this and quoted one of less than 200 people. The China Study by Dr. Colin Campbell was a huge study and proved that arteries once clogged can be opened through the proper diet. There are photos in a book by Dr. Caldwell Esselstyn that show the opening of clogged arteries through photos, due to a completely plant-based lifestyle. Reversal of my condition is iffy because I have congestive heart failure, which may mean permanent damage. But I am following a plant-based diet anyway, because I don't want the other problems eating animals and their secretions cause. I have reduced my A1Cs to 5.3 and have no more diabetic meds and also reduced my blood pressure. I will take those as victories. I feel good and do almost everything I used to do before the heart failure, and will soon be 78 and still kicking. What you eat is what determines your health. I wholeheartedly believe that from my own experience.
