“The high prevalence of dietary saturated fat in this population suggests that high dietary saturated fat consumption may be risk averse.”
Previous research has found that low-glycemic-index diet, which was introduced in the 19th century, increased heart disease risk. According to several studies, diet high in fruits and vegetables increased serum markers of risk for the developing heart, including LDL/C, which is an independent risk factor for atherosclerosis.
For example, a study published last year in the journal the American Journal of Clinical Investigation also found that a low-calorie, low-fat diet associated with an increased risk of early death occurred before age 65, while a high-fiber diet, which was introduced early in the 20s earlier in the century, increased the risk. A recent study of more than 1,000 US adults associated a high-fiber diet with a 23% lower risk for death from early death compared to a low-fiber diet and a higher-fiber diet, published in the Lancet, reported that this diet was associated with a greater risk of early death in that age group. An additional study reported that a high-fiber diet in an urbanized population may have increased the risk of early death and the onset of angina with long-standing blood pressure, heart disease, or stroke, especially after a 30-year survival period.
“We were able to control for many of the confounding variables, so there are little known dietary variables that might have influenced the association,” she said. “So, if you’re a high-fiber, low-fat diet, it is possible, for example, that you have a higher prevalence of cardiovascular disease in a study population and that might explain the association.”
