ScienceDaily (July 18, 2008) — Scientists have long been puzzled by how the Masai can avoid cardiovascular disease despite having a diet rich in animal fats. Researchers at Karolinska Institutet believe that their secret is in their regular walking.
There is strong evidence that the high consumption of animal fats increases the risk of developing cardiovascular disease. Many scientists have therefore been surprised that the nomadic Masai of Kenya and Tanzania are seldom afflicted by the disease, despite having a diet that is rich in animal fats and deficient in carbohydrates.
This fact, which has been known to scientists for 40 years, has raised speculations that the Masai are genetically protected from cardiovascular disease. Now, a unique study by Dr Julia Mbalilaki in association with colleagues from Norway and Tanzania, suggests that the reason is more likely to be the Masai’s active lifestyle. (Full Story at sd)
I like how the first assumption was, "Oh, they must have some different genes." Of course, it turns out that the blokes just walk a lot.
