printScientists are reluctantly, if slowly, arriving at the following conclusion: Carbs kill. The evidence is hard to refute. (Karen De Coster was right, warning way back about “Frankenfoods and The Government’s Fraudulent Food Pyramid.” ) The latest medical mea culpa—from Cambridge University, no less—is summarized by Dr. Barbara H. Roberts at The Daily Beast:
… There are many other recognized risk factors the the American Heart Association ignored, including blood sugar level, low “good” (HDL) cholesterol, insulin levels, and body weight—all of these are influenced by diet.
In fact, most people who have heart attacks don’t have elevations in bad cholesterol. They are much more likely to have metabolic syndrome—a condition that puts you at high risk for diabetes and heart disease. Metabolic syndrome is defined when you have three of the following: high triglycerides (blood fats), high blood sugar, high blood pressure, low “good” cholesterol (HDL-C), and a large abdomen measurement (abdominal obesity).
Interestingly enough, blood triglycerides do not go up with eating fat—they go up if you eat a diet high in processed grains, starches, and sugar. Unfortunately for the proponents of high-carbohydrate diets, high blood triglycerides are a major risk factor for heart disease. In addition, low fat/high carb diets lower protective “good” cholesterol and raise insulin. These diets are implicated in the development of diabetes, which is a potent risk factor for developing heart disease.
The writers of the 2013 statin guidelines based their recommendations on studies that looked at the reduction in the risk of events like heart attacks in people treated with statins, compared to people on a placebo. The AHA dietary guidelines do not cite any diet studies that looked at whether following a specific diet lowered the risk of developing cardiac events—yet they are giving dietary advice. Why?
There might be two plausible reasons. One is the AHA’s moneymaking “Heart Check Program.” The second is the conflict of interest (and curious beliefs) of Robert Eckel—the co-chair of the panel that wrote the guidelines.
The AHA introduced the Heart Check Program in 1995 and it has been quite the moneymaker, as the AHA sells the Heart Check stamp-of-approval to food manufacturers. Food companies shell out between $1,000 and $7,500 to be certified by the Heart Check Program—and then there are yearly renewal fees. The program currently endorses 889 foods as “heart-healthy.”
And the Heart Check Program is not the only way the AHA benefits from Big Food companies. In their annual report for 2012-2013, the AHA lists among its lifetime donors of $1 million or more Conagra, Quaker Oats, and Campbell Soups, among others.
Forty-five percent of these “heart healthy” foods—over 400 of them—are meat; 92 are processed meats—which have been shown to have either neutral or negative effects on heart health.
Even more problematic are the foods containing added sugar. The AHA recommends that women consume less than 6 teaspoons (100 calories) of sugar a day and less than 9 teaspoons (150 calories) for men. Yet there are items that get the nod of approval from the Heart Check program despite being near or at the sugar limit, like Bruce’s Yams Candied Sweet Potatoes and Healthy Choice Salisbury Steak. Indeed, until 2010, the Heart Check imprimatur was stamped on a drink called Chocolate Moose Attack, which contained more sugar per ounce than regular Pepsi.
And until this year, Heart Check approved many foods with trans-fats, which raise bad cholesterol and lower good cholesterol, among other deleterious effects on health, like increasing inflammation and the laying down of calcium in arteries.
Like the dietary guidelines, the AHA Heart Check Program appears to address only the effect of foods on cholesterol level and blood pressure. Meanwhile, since the 1970s, our yearly sugar consumption has skyrocketed along with the incidence of diabetes and obesity. …”
