The Individual Nutrients – Fats Č Fats are not simply an unimportant part of our diet, they are contributors to our total well being. Fats contribute to most of our vital organs. They are found in eggs, fish, meat, poultry, milk, cheese, and in smaller quantities in oils, grains, and legumes. All fats are either solid or liquid at room temperature, but are most commonly broken down into three types depending on their chemical structure. These are monounsaturated fats, polyunsaturated fats, and saturated fats.
Monounsaturated fats tend to remain liquid at room temperature, but leaner fats may undergo partial melting. Polyunsaturated fats are most often liquid at room temperature but thinner fats experience partial melting due to the formation of double bonds during the hydrogenation process. Saturated fats, however, remain solid at room temperature and double bonds are not formed, thus they are referred to as firmly frozen fats.
In nutrition, fats are considered either as rich or as low in calories. A gram of fat contains nine calories, and one gram of saturated fat contains about six calories. Monounsaturated fats, polyunsaturated fats, and saturated fats are all considered desirable fats for the body. Triglycerides are also classified as saturated fats, and they are composed of three kinds of fatty acids based on how closely they resemble triglycerides.
In relation to dietary fat, the type off fats provides some clues as to their relative importance. Fats high in energy are absorbed at a faster rate. However, the effect is not as great as energy from other sources. Fats with high energy content are also potentially dangerous for athletes, as they increase triglyceride levels, which enhance the risk of atherosclerosis and heart disease.
Saturated fats are classed as ‘lingual fats’ and have been targeted by the media in the run up to the low fat craze. These fats are particularly the ones that are solid at room temperature, like butter and shortening. In the 1980s dietary fat was targeted as the villain in the fight against coronary heart disease, as evidence rooted them as responsible for the development of this disease. While some amount of fat is needed for the body to function, an excess that is consumed in the form of saturated fats increases the risk of heart disease. These fats are also what constitute the most harmful servings of caloric fat; trans fats.
The problem with these high-fat foods is the hydrophilic nature of their chemistry. ขายตัว These fats tend to attract water, and can thus assume a more corrosive state inside the human body where disease and aging thrive. Nevertheless, a high fat diet should never be consumed in excess and saturated fats should be limited to 10% or less of daily calories.
In addition to avoiding saturated fats, the concentration of trans fats may also be high in a typical high fat diet. ดูหนังออนไลน์ For every gram of fat that is consumed, 4 grams of saturated fat are also burned, that is, saturated fat has 2.5 times the caloric cost of polyunsaturated fat when it comes to burning fat. Monounsaturated fats, however, do have a slight advantage over polyunsaturated in that they reduce the risk of heart disease.
Despite evidence pointing to the superior healthfulness of monounsaturated fats, choosing them over polyunsaturated can present problems for many individuals. แตกคาปาก Look at our bodies in this way. Monounsaturated fats are more water soluble than polyunsaturated, both with ease and safety to the body. High levels of trans fats and saturated fats can both act as pro-inflammatory agents to the body, and many individuals are sensitive or allergic to these types of fat.
The most common foods high in polyunsaturated fats include soybean oil, corn oil, sunflower oil, safflower oil, sesame oil, and peanut oil, and the typical treatment for any illness is to give the body some amount of anti-inflammatory agents to deal with the problem. สายบู๊ต้องดู! These anti-inflammatory agents can be found in the fats of cold-water fatty fish like salmon and tuna as well as walnuts and almonds.
Walnuts are also a great choice for getting your needed dose of omega-3 fats. For people with heart disease, omega-3 fats are shown to improve circulation by shrinking blood vessels, and lowering blood pressure as well. This is why consuming some level of seafood is highly recommended for those who are concerned about their heart’s health.
The fats contained in walnuts are also shown to slow the breaking down of the LDL, or bad cholesterol, in the bloodstream. This is similar to the case with salmon and tuna, เปิดซิง which are also excellent sources of omega-3 fats.
In the case of choosing between butter and cheese, for example, the obvious answer is to go for the butter.
