If you’re worried about the best sources of fat, consider the results from a recent clinical trial. The study investigated the effect of consumption of fatty acids and selected nutrients, along with regular physical activity, on cardiovascular risk factors in rats. The rats were divided into seven groups. Group 1: regular food and drinking water; Group 2: same as Group 1 + physical activity; Group 3: same as Group 2 + calcium, vitamin D, and boron; Group 4: same as Group 3 + canola oil; Group 5: same as Group 3 + sunflower oil; Group 6: same as Group 3 + a mix of sunflower oil and canola oil; and Group 7: same as Group 3 + coconut oil.
The rats were treated for eight weeks, after which the researchers performed some tests. Here are some of their interesting results:
— Group 5 consumed less food
— In Groups 6 and 7, plasma levels of cholesterol and LDL cholesterol increased significantly
— Analysis of data among Group 4 to 7 (the oil-consuming groups) and Group 3 revealed significant differences in cholesterol, triglycerides, and C- reactive protein
— Levels of testosterone and free testosterone in Group 7 increased
The researchers say their findings show that canola oil and sunflower oil, separately, showed beneficial impacts on heart disease risk factors; whereas their combination had negative impacts on lipid profile. Coconut oil seemed to provide health benefits in terms of cardiovascular protection.
The message seems to be to choose your fats carefully, but definitely include them in your diet. Fats can work for or against your health depending on which ones you use and how you combine them.
