You’ve probably heard that the typical American diet-with its high emphasis on fatty cuts of meat-is what causes heart disease. We’re wondering, however, if anyone ever told you about the high-fat diets of the Masai? No, you say? That’s the answer we expected you to give because many industry groups would probably rather you didn’t know about the Masai and others who seem to thrive on a high-fat diet. It seems to confuse the low-fat message, doesn’t it?
The Masai are a tribe in Africa that consumes a diet that is almost 100 percent saturated fat. Whole milk and beef are dietary staples. Do the Masai drop dead from heart attacks at age 40? No, they do not. The members of this tribe do not suffer from heart disease. They just don’t get it. Are they genetic anomalies? Do they lack a heart disease gene? It’s not likely.
The Masai are just one of many species around the globe that thrives on a diet rich in fat. The Inuit are another example. They live in North America and also develop little to no heart disease, obesity and diabetes. They also eat a considerable amount of saturated fat, mostly from whales, fish, seals, and other animals. Is it possible that the Inuit, like the Masai, lack the heart disease and diabetes genes? It’s possible, but not likely. You want to know why? Canadian Arctic explorer Vilhjalmur Stefansson lived with the Inuit for a year and consumed their fatty diet. He suffered no ill health effects.
How can this be? How can so many populations from so many different places in the world consume diets rich in animal fat and manage to stay healthy? They can because animal fat alone is not what causes heart disease, cancer, and other health problems. It’s not until members of these healthy-fat-eating societies start eating typical American convenience foods such as fast food and processed foods that their rates of heart disease start to climb. It appears that natural sources of fat are not what make Americans more likely to suffer a heart attack than folks living in other countries around the world. It’s the sugar, processed flour and starch, and synthetic fats.
ndeed, consider that a recent Harvard study followed the eating habits and health outcomes of more than 80,000 nurses over 2 decades. Women who consimed higher amounts of carbohydrates from refined sugar and highly processed foods nearly doubled their risk of heart disease compared to women who ate a lower carbohydrate diet. This latter group actually cut their risk of heart disease by 30 percent on average. At least five other studies conducted at prestigious institutions such as Duke University and the University of Pennsylvania show similar results for heart disease reduction.
Finally, a 2-year study that compared a high-fat, low-carb diet and the Mediterranean die (which emphasizes poultry, fish, olive oil, and nuts) determined that the low-carb dieters lost nearly twice as much weight as the low-fat dieters. And they were healthier at the end of the study. Their cholesterol profiles improved the most.
