Unexplored factors like genetics and lifestyle are not fully considered in the population surveys and could explain the French paradox. The French paradox remains controversial, and the AHA is correct to point out that there is no firm scientific basis for advocating alcohol consumption to reduce heart disease risk. Foods and beverages qualifying for the heart-check mark include those that are considered low fat, low saturated fat, low cholesterol and low sodium, and have at least 10 percent of the recommended daily value of one or more of vitamin A, vitamin C, calcium, iron or dietary fiber. The problem is that the theories underlying the Food Certification Program are like the French paradox unproven. But the science isn't quite there.
Heart disease is complex.
Lifestyle factors, including diet, may play a role in some people. But scientific uncertainty abounds. The evidence behind the AHA's Food Certification Program is weak just like evidence of the French paradox. Money and politics. Several hundred products now carry the heart-check logo.
