Why don the different types of fat on food labels add up to equal “total fat”?
These numbers don’t always add up as you’d expect, even if content of saturated, trans, polyunsaturated and monounsaturated fatty acids (building blocks of fat) are all listed. Total fat also includes a substance called “glycerol,” which is one of the building blocks for fats that itself does not act like a fat at all. The way that figures are rounded up or down slightly for use on food labels can also send the total off a bit. Q: Does someone’s blood type indicate the kind of diet that’s best for him or her? A: No. You may have heard of a diet based on the idea that blood type indicates whether your genetic ancestors were hunters, farmers or nomads, which in turn tells you whether or not you should eat specific foods, such as meat, dairy foods and wheat. Supposedly, eating appropriately for your “type” helps control weight and prevents cancer and other health problems.
