Natural fatty acids may be saturated or unsaturated, and as the following data indicate, the saturated acids have higher melting points than unsaturated acids of corresponding size. The double bonds in the unsaturated compounds listed on the right are all cis (or Z).
My best diet is Basically organic veggies, veggie juice and organic meats. No processed food at all. No fruit juice, no artificial sweetners. No sugar, caffene, wheat, processed grains (whole grains are fine). Only occassional fresh fruit, don't let it become a sugar substitute.
The Flexitarian diet, which emphasizes fruits, veggies, whole grains, and plant-based protein, is a smart and healthy choice. It outperformed many of its competitors, with particularly high scores in nutritional completeness, easiness to follow, and long-term weight loss.
