“The Best Diet for Diabetes” There are all sorts of different scoring systems to rate diet quality. My favorite, for its simplicity, is the dietary phytochemical index: a fancy name for a simple concept. It’s just the percentage of your calories from whole plant foods, so 0 to 100. The average American diet has a score of 12.
Twelve out of a hundred; so, like on a scale of one to ten, our diet is a one. You can split people up based on how they score, and show how the higher you score the better your metabolic markers when it comes to diabetes risk. There appears to be like this stepwise drop in insulin resistance and insulin-producing beta-cell dysfunction as you eat more and more plant-based.
And that highest group was only scoring about 30, less than a third of their diet was whole plant foods, but better than the lowest, which was down around the standard American diet. No wonder diets centered around plants, emphasizing legumes— beans, split peas, chickpeas and lentils— whole grains, vegetables, fruits, nuts and seeds, and discouraging most or all animal products are especially potent in preventing type 2 diabetes, and as a little bonus has been associated with much lower rates of obesity, hypertension, hyperlipidemia, cardiovascular mortality, and cancer.
And not just preventing type 2 diabetes but treating it as well. A systematic review and meta-analysis found that the consumption of vegetarian diets is associated with improved blood sugar control, but how much improved? Here’s one of the latest trials. The effect of a strictly plant-based diet centered around brown rice—it was done in Asia—versus the conventional diabetic diet on blood sugar control of patients with type 2 diabetes: a 12-week randomized clinical trial.
For the diabetic control diet, they set up food exchanges and calculated specific calorie and portion controls, whereas on the plant-based diet people could eat much as they want; that’s one of the benefits. The emphasis is on food quality rather than quantity, and they still actually lost more weight.
But even after controlling for the greater abdominal fat loss in the plant-based group, they still won out. Of course, it only works if you actually do it, but those that pretty much stuck to the healthier diet dropped their A1c levels 0.9%, which is what you get taking the leading diabetes drug, but of course only with good side effects.
Yeah, but would it work in an underserved population? The impact of a plant-based diet support program on mitigating type 2 diabetes in San Bernadino, the poorest city of its size in California. A randomized controlled trial, but not of a plant-based diet itself as the title suggests, but of just an education program telling people about the benefits of a plant-based diet for diabetes, and then it was up to them.
And still got a significant improvement in blood sugar control. Here are the numbers. Got a little better in the control group, but way better in the plant-based instruction and support group. And more plant-based diets are not just effective in the prevention and management of diabetes, but also its complications.
Check this out. One of the most devastating complications of diabetes is kidney failure. This shows the decline in kidney function in eight diabetics in the one or two years before switching their diets. They all showed this steady, inexorable decline on a fast track to complete kidney failure and dialysis.
But then they switched to a special supplemented vegan diet, and their kidney decline was stopped in its tracks. Imagine if they had switched a year or two earlier! Most diabetics don’t actually end up on dialysis though because they die first. Cardiovascular disease is the major cause of premature mortality among diabetics; that’s why plant-based diets are perfect.
There is a general scientific consensus that the elements of a whole-foods plant-based diet— legumes, whole grains, fruits, vegetables, and nuts, with limited or no intake of processed foods and animal products— are highly beneficial for preventing and treating type 2 diabetes. Equally important, plant-based diets address the bigger picture by simultaneously treating cardiovascular disease, our #1 killer, along with obesity, high blood pressure, lowering inflammation, and we can throw cancer into the mix too, our #2 killer.
The bottom line is that the case for using a plant-based diet to reduce the burden of diabetes and improve overall health has never been stronger.
