Diabetes
A recent study found that people who ate diets high in red meat, especially processed red meat, had a higher risk of type 2 diabetes than those who rarely ate red or processed meat. (7) For each additional serving a day of red meat or processed red meat that study participants ate, their risk of diabetes rose 12 and 32 percent, respectively.
Substituting one serving of nuts, low-fat dairy products, or whole grains for a serving of red meat each day lowered the risk of developing type 2 diabetes by an estimated 16 to 35 percent.
Another study also shows that red meat consumption may increase risk of type 2 diabetes. Researchers found that people who started eating more red meat than usual were found to have a 50% increased risk of developing type 2 diabetes during the next four years, and researchers also found that those who reduced red meat consumption lowered their type 2 diabetes risk by 14% over a 10-year follow-up period.
More evidence that protein quality matters comes from a 20-year study that looked at the relationship between low-carbohydrate diets and type 2 diabetes in women. Low-carbohydrate diets that were high in vegetable sources of fat and protein modestly reduced the risk of type 2 diabetes. (13) But low-carbohydrate diets that were high in animal sources of protein or fat did not show this benefit.
For type 1 diabetes (formerly called juvenile or insulin-dependent diabetes), proteins found in cow’s milk have been implicated in the development of the disease in babies with a predisposition to the disease, but research remains inconclusive.
Osteoporosis
Digesting protein releases acids into the bloodstream, which the body usually neutralizes with calcium and other buffering agents. Eating lots of protein, then, requires a lot of calcium – and some of this may be pulled from bone.
Protein and Weight Control
The same high-protein foods that are good choices for disease prevention may also help with weight control. Researchers at Harvard School of Public Health followed the diet and lifestyle habits of 120,000 men and women for up to 20 years, looking at how small changes contributed to weight gain over time. (20)
Those who ate more red and processed meat over the course of the study gained more weight, about one extra pound every four years, while those who ate more nuts over the course of the study gained less weight, about a half pound less every four years.
One study showed that eating approximately one daily serving of beans, chickpeas, lentils or peas can increase fullness, which may lead to better weight management and weight loss. (21)
There’s no need to go overboard on protein. Though some studies show benefits of high-protein, low-carbohydrate diets in the short term, avoiding fruits and whole grains means missing out on healthful fiber, vitamins, minerals, and other phytonutrients.
