David Perlmutter, MD, has a written a book entitled, “Grain Brain” that is a New York Times best seller. Perlmutter is a neurologist who claims that eating too many carbohydrates is killing our brain cells. Of course there are those who believe that Perlmutter is overstating the case when he says that eating too much starchy, high gluten, sugary foods leads to a wide array of diseases, including diabetes, and early onset of Alzheimers disease. Still Perlmutter is standing his ground that Americans especially should stop eating a whole array of high sugary carb foods in excess.
Perlmutter had done his research to defend his position that the human body need more protein than carbohydrates in the form of white flour, processed sugar, all grains, including all cereals, and a wide swatch of other high carb foods. Perlmutter says that in 1992 the government told us that we needed to be on a low-fat diet. He says that within 10 years a low-fat, high carb diet led to a three-fold increase in diabetes in America. The number of people diagnosed with diabetes in the U.S. has nearly tripled in the last twenty years, according to the Center for Disease Control, the CDC. In 1992, 7.5 million people had a diagnosis. By 2002, the number was 13.6 million. By 2011 it was 20.9 million Perlmutter claims that the food chart is all wrong-that carbos should not be more than 20 percent of anyone’s diet.
Perlmutter believes that eating more of what the U. S. Department of Agriculture is producing for us is not good for us—it might be good for American farmers but not for the human body that needs more meat than oatmeal. Perlmutter says that diets that are high in fats lower the cardiovascular risk factors and reduce the risk for dementia and Alzheimers disease. Research at the Mayo Clinic found that people on high fat diets had a 44-percent risk reduction for developing dementia. Those on high carbo diets had an 89 percent increased risk.
Perlmutter is not the first doctor to suggest a high fat-low carbo diet. The cornerstone food of the Atkins diet was plenty of meat, poultry and fish and not too much cake, pies, mash potatoes, mac and cheese, cereal and a wide range of other high carbos. The Atkins diet was also challenged as being out of balance since it did not put a limit of the intake of high fat meat. Instead of eating carbos the Atkins diet suggested eating plenty of green vegetables instead of eating lots of sugary, starchy foods.
Perlmutter is yet another doctor to suggest that what we eat has a direct bearing on the quality of our health. Perlmutter has nothing to gain, except book sales, from advocating a low carbo diet. What would American’s Doctor, Dr. Oz say about this? Seems he might be willing to concede that a high carbo diet can be detrimental to one’s health—at least depending on what the carbos are. Then there are those who point to other cultures where high a diet high in carbos is the mainstay of the daily intake of food. But these people in New Guinea, Greece and a few other islands have a totally different lifestyle compared to the “sit on your butt” American way of life.
Perlmutter book is worth the read if for no other reason than to cause a reexamination of what we eat and how it affects our health.
