Peanut butter is good for the heart, according to a study from Harvard Medical School, published in the journal Journal of Nutrition .
The scientists followed more than 6000 women with diabetes type 2 for twelve years. Women who ate nuts or peanut butter five or more times a week during the beginning of the study had 40 percent less cardiovascular disease than the women who rarely or never ate nuts or peanut butter. They had lower levels of the 'bad' LDL cholesterol, the 'good' HDL cholesterol remained unchanged.
Peanut butter is somewhat comparable to olive oil in terms of fat composition, but remains fat in any case. Nuts are high in healthy monounsaturated fats
Still, it would be hasty to recommend a higher consumption of nuts based on the study, especially because the study does not distinguish between the different types and types of nuts.
