Most of us have heard the term saturated fat all our lives without understanding it. How can fat be "saturated?" Does that mean it is all wet? And that unsaturated fatty dry and if so, of polyunsaturated fat is dry in more ways?
Let's do it now. It's a shame to go through life ignoring the facts that could prevent a heart attack or cancer.
Fats in general
Fat molecules are chains of carbon atoms with hydrogen atoms along the sides of the centipede legs. (Remember this. And 'the only chemical you are here.)
Fat is also one of four "energy nutrients" with carbohydrates, protein and alcohol. Energy nutrients provide calories, which the brain power (25 watts in most of us) and muscles (in watts if you're Lance Armstrong), so you can solve quadratic equations and the wax from the Pathfinder.
Fat is a great way to store energy. One gram of fat (about a quarter teaspoon) contains nine calories, compared to only four calories per gram of protein or carbohydrate. (Alcohol contains seven calories per gram, which means it is an excellent source of energy if you can live with effectsh Shide.)
Yes, some fats are bad for you. We'll get there.
Saturated fat
Every time a fat molecule has all the hydrogen atoms that can accept, which is said to be "saturated." Think of it as the millipede bring 50 pairs of shoes.
Most saturated fats are solid at room temperature. (There goes my theory of "wet" - saturated fats really feel dry.) They also have a tendency to come from foods of animal origin: Jims butter, meat, eggs, milk and Slim.
Because saturated fats raise blood cholesterol levels and contribute to heart disease and stroke, most experts recommend not to receive more than 10 percent of your calories from fat. Power supply weight and nutrition coaching software enables your personal daily allowance (PDA) of saturated fat at that level, but you can remove it if you think of having a stroke might be fun.
Saturated fats have also been implicated in some cancers, including breast cancer.
Polyunsaturated fatty
Polyunsaturated fat, millipedes has at least two pairs of shoes are missing, and sometimes much more. Most of the polyunsaturated fatty acids are liquid at room temperature. Most also come from vegetables. You know they are corn oil, peanut oil, and Pam.
Because polyunsaturated fatty acids are fairly neutral effect on blood cholesterol, saturated fats are much better. Not without problems, though. We explain that the minute.
Monounsaturated fats
In monounsaturated fat, the centipede is missing exactly one pair of shoes. (They are under the sofa, somewhere, for sure.) This is a special state that gives the properties of the fat seems wonderfully beneficial, otherwise, had also heard of the television ads touting the benefits of di triunsaturated-or fat.
The best known of monounsaturated fat is olive oil, but the power of the power of the Diet Foods feature the richest sources of oleic safflower oil, and macadamiapähkinöitä. (Most nuts are rich in monounsaturated fat).
Although many people think that all fats are bad, monounsaturated may actually protect against heart disease and stroke by reducing blood cholesterol. So long as the total fat content is too high, the majority of monounsaturated fat, which is better. (Do not take this to the end, however. You never know what the new research could be in a few years.)
In general, the American Heart Association (http://www.americanheart.org) recommends taking no more than 30-35 percent of their calories from fat and no more than 10 percent of the saturated variety.
Trans Fat
This is the attack of polyunsaturated fats.
Trans fats occur when food manufacturers turn vegetable oils in margarine, Crisco, and other products from their hydrogenation, in effect, set the shoes so fat millipedes, fixed (or at least sticky) at room temperature. This is to make butter and lard substitutes that do not clog arteries.
In recent years, however, the researchers found that trans fats can scribble your pipes just as bad as the Moo Goo done. Initially the evidence was weak and caused a heated debate, especially on the nights of poker among the guys in Land O Lakes, and I can not believe it's not butter. But today, it is clear that people must use butter and margarine sparingly. Or better yet, dip the bread in a saucer of olive oil.
In conclusion
Keep fat intake low. (Power History nutritious diet is a very good result here.)
Get off the fat from plants, not animals.
Try to avoid foods with hydrogenated on the label.
Learn how the olive oil and nuts, but do not overdo it.
