Fat is one of the three main types ofmacronutrients.[1] Fats are found in many foods. They are made ofmacromolecules calledlipids. Lipids are based on long-chainfatty acids. Some of these areessential because the body cannot make them.
Unsaturated fats are liquid at room temperature. They are considered useful fats because they can improve bloodcholesterol levels, and ease heart rhythms. Most vegetable oils are liquid at room temperature and have unsaturated fats. There are two kinds of unsaturated fats, Mono-unsaturated fats, and polyunsaturated fats.[3] It is commonly found inavocados,nuts,peanuts,seeds, wild fish, andolive oil. For polyunsaturated fats, it is recommended to have an omega-3 to omega-6 ratio of 1:1.[4][5]
This is the structure of saturated fat, anester with the chemical formula C45H86O6, we can also called itTrimyristin, a saturated fat which is thetriglyceride ofmyristic acid.
Saturated fats will likely have no benefits. They are mainly found in animal foods, but a few plant foods are also high in saturated fats. Too much saturated fat in your diet can lead to heart disease and other health problems, such as gaining weight or increasing the risk of heart disease or stroke. People should not eat too much saturated fats. You should limit saturated fat to less than 10% of your daily calories.[6] It can usually be found in dairy products, meat products, and grain-based desserts.
Trans fatty acids are commonly called trans fats. They are a kind of unsaturated fat. Trans fats may be natural or they may be made.[7] Naturally-occurring trans fats are found in theguts of some animals and foods which are made from these animals. Artificial trans fats are made in an industrial process. The process adds hydrogen to liquid vegetable oils to make them more solid. Trans fats are worse forcholesterol levels than saturated fats. They are most likely found in frying, baked goods, andprocessed foods.
Fats are used to absorb or get nutrients, like Fat-soluble Vitamins for humans. They are used as a source of backup energy in cases when carbohydrates are not available, or people can not use it at that time. People need more than 20 to 35% of daily calories from fat. Also, fats play a role in helping people's body maintain or keep the core (center) temperature.[8] However, too much fat or the wrong kinds are also harmful, in other words, fats can have bad effects on human's bodies.
Bad fats, in other words, trans fats, have no known health benefits and will damage someone's heart and take them away from healthy. People might get diseases like blindness, which means they can not see anything because of having too much cholesterol and other fats. Most of the foods that contain these types of fats are solid at room temperature, such as butter and animal meat. On the other hand, good fats are naturally found in foods and will not damage the human's organs. The example foods of good fats are avocados, eggs, and nuts.
Unsaturated fatty acids are very important. They are called by where theirdouble bond is placed. Omega-3 fatty acids (ω-3) and omega-6 fatty acids (ω-6) are essential: you need them both. They help build longer molecules which do cell signaling in different tissues. There are over 20 different signaling paths that control a wide array of bodily functions.
These foods are made of trans fats. Obesity can easily be caused if too much of these foods are eaten.
Medium-chaintriglycerides are good for burning fat. They are easily absorbed, digested, and reused as energy. Eating milk fat, palm oil, and coconut oil will burn fat because they contain medium-chain triglycerides.[9]
Avocados are a source ofmonounsaturated fats. It also has medium-chain triglycerides that can be used to burn fat.
Fat can be important for people, but too much fat is bad. The fat people eat can provide energy for them. Not all fatty foods are good for health, such as pizza, french fries, and hamburgers. The fat from those may cause the person become fatter, and their health may become terrible.[10]
Fats also provide long-term energy for humans and, in cold climates, a layer ofinsulation to keep the body warm. They help the body use thevitamins found in foods. Fats are also good for the skin and hair.Olive oil is an especially healthy fat. Many types offish also contain healthy fat, for examplesalmon,sardines,herring, andtuna. But if too much fat collects in the body, a person can become too heavy. The energy given by fats is used by moving around or exercising. Some vegetables like celery or carrots contribute much less to the bodies fat supply. Though being very important for the human body, it can also be harmful in large amounts.
Fatty liver is one of the diseases that can be caused by fat
Too much fat (especially Trans fats) in the body can cause diseases. Indeed,obesity, meaning too much fat, is sometimes called a disease itself. One disease from excess fat is called "fatty liver". It is a condition which can be resolved by eating different foods. Fatty liver is when someone has too many fats in theirliver, but it can also be associated byalcohol ormetabolic syndrome. Fatty liver can be fixed by exercise and better diet. This is one of the hidden danger of fats.
Another hidden danger of fats is that it can cause someheart diseases. One example is Heart Failure.Heart Failure is an illness that does not have enough heart pumps blood. It lowers the leading of blood flow.
Exercise is good for health
The main ways to avoid these issues are exercise and good eating.Exercise reduces excess body fat and strengthens the body.Healthy diet keeps nutritious balance in your body and helps remove the fats in your body.
