Carbs vs. protein vs. mono fats.Experts agree that it's a good idea to minimize bad fats (saturated and trans). But it's not clear whether to replace them with carbohydrates, protein, or monounsaturated fats. The OmniHeart Trial gave men and women with high blood pressure or pre-hypertension one of three diets that had roughly equal amounts of saturated fat saturated fat, any solid fat that is an ester of glycerol and a saturated fatty acid. The molecules of a saturated fat have only single bonds between carbon atoms; if double bonds are present in the fatty acid portion of the molecule, the fat is said to be , sodium, potassium, calcium, fiber, and calories. However: * the higher-protein diet had slightly more beans, low-fat dairy foods, poultry, and egg substitutes, * the higher-carb diet had more sweets and desserts and slightly more fruit and juices, and * the higher-mono diet had more fats and oils and slightly more vegetables. Compared to the higher-carb diet, the higher-protein diet lowered blood pressure, LDL LDL - ["LDL: A Logic-Based Data-Language", S. Tsur et al, Proc VLDB 1986, Kyoto Japan, Aug 1986, pp.33-41]. ("bad") cholesterol, and triglycerides Triglycerides Fatty compounds synthesized from carbohydrates during the process of digestion and stored in the body's adipose (fat) tissues. High levels of triglycerides in the blood are associated with insulin resistance.

Compared to the higher-carb diet, the higher-mono diet lowered blood pressure and triglycerides and raised HDL cholesterol HDL cholesterol n. See high-density lipoprotein.

What to do: Either higher-protein or higher-mono diets beat higher-carb diets, say the authors. But their results might not apply to a higher-carb diet rich in whole grains rather than sweets and desserts. In any case, it makes sense to replace bad fats (in fatty meats, high-fat dairy, butter, etc.) with beans, vegetables, low-fat dairy foods, oils, and nuts instead of desserts, sweets, and fruit juices. But don't go overboard: none of these diets were extremely high or low in protein, fat, or carbs.
