Nutrition -- Fat

The average American eats too much fat and too much of the wrong kinds of fat. A first analysis gives us 3 types of fat: Trans fat is the easy one to talk about. It has been outlawed! Small amounts are naturally present in meats and animal derived products, so you may see a gram or less listed on some nutrition facts breakdowns. But given that is is outlawed, we can direct our attention elsewhere.

Saturated fat is the one to watch. There is lots of this in dairy (butter and cheese) and meats, especially red meats. Chicken is not an exemption, nor is pork. And there is plenty in eggs.

Unsaturated fats can be acceptable or even good -- in moderation. You get this (without companion saturated fat) from plant based foods and fish. Nuts and seeds are good sources. Olive and canola oil. Peanut butter.
There are 2 kinds:

You occasionally (rarely) see these broken out on nutrition facts tables, usually because the company is proud of them. Polyunsaturated include the Omega-3 and Omega-6 you often hear about.

How much fat?

Fats are the most energy dense foods (calories per gram). So be careful.

One guide says that fat should make up 30 percent of your daily calories, avoiding saturated fats in the process.

You heart various limits for saturated fat. Some say 10 percent, but they are basically lying to you because they don't think you could manage what you really should. The better answer is 5-6 percent of your total calories.

Now I read this and think -- this is more or less useless if I don't know my total daily calories. I want to be able to tally up grams of saturated fat based on nutrition facts labels and adjust my diet accordingly. So here is my starting point. I assume a 2000 calorie per day intake (which seems to be reasonable for someone who doesn't eat like a hog). 10 percent of this would be 200 calories, 5 percent would be 100 calories. A gram of fat yields 10 calories, so our limit is then 10 grams per day of saturated fat.

Next we should look into limits for cholesterol.
