Oprah is setting a positive example for Americans by exploring a vegan diet ("Oprah checks out the vegan diet: Will America follow?" Tribune, May 27).
As a physician and an endocrinologist, I know that making healthy dietary choices can make a real difference in our health and well-being.
Replacing meat and dairy products with low-fat, high-fiber vegetarian foods can help lower blood pressure and cholesterol, shed unwanted pounds, and even reverse some chronic health problems such as metabolic syndrome and Type 2 diabetes or even heart disease.
The American Dietetic Association endorses a well-planned, plant-based diet as completely healthy for all stages of life.
Poor dietary and lifestyle choices have fueled our nation's obesity and diabetes crisis. But moving toward - and sticking to - a plant-based diet could help Americans stay slim and healthy for life.
