FAT

​​ Fats are nutrients in food that the body uses to build cell membranes, nerve tissue (including the brain), and hormones. The body also uses fat as fuel.

Fats are also called 'fatty acids' or 'lipids. ' fatty acid is  important component of lipids (fat-soluble components of living cells) in plants, animals, and microorganisms.Fats in our body are made up of three molecules joined together. This three-molecule structure is called a “triglyceride”. Most of the fat we need is made by our bodies, but there are some fats our bodies cannot make. 

Fatty acids are the building blocks of the fat in our bodies and in the food we eat. During digestion, the body breaks down fats into fatty acids, which can then be absorbed into the blood. Fatty acid molecules are usually joined together in groups of three, forming a molecule called a triglyceride. They are carboxylic acids with long aliphatic chains which may be straight or branched, saturated or unsaturated

Fat is a source of essential fatty acids, which the body cannot make itself. Fat helps the body absorb vitamin A, vitamin D and vitamin E. These vitamins are fat-soluble, which means they can only be absorbed with the help of fats.

Fat is a type of nutrient, and just like protein and carbohydrates, your body needs some fat for energy, to absorb vitamins, and to protect your heart and ...

Dietary fats are essential to give your body energy and to support cell function. They also help protect your organs and help keep your body warm. Fats help your body absorb some nutrients and produce important hormones, too

Main types of fats?

Fatty acids can be divided into four general categories: saturated, monounsaturated, polyunsaturated, and trans fats. Saturated fatty acids and trans fats are associated with an increased risk of coronary heart disease.

Fatty acids foods

Fish and other seafood (especially cold-water fatty fish, such as salmon, mackerel, tuna, herring, and sardines) Nuts and seeds (such as flaxseed, chia seeds, and walnuts) Plant oils (such as flaxseed oil, soybean oil, and canola oil)  Dark chocolate, Eggs, Avocado,  Flaxseed, Nuts. seed butte, Fatty fish. Fatty fish contain large amounts of unsaturated and omega-3 fatty acids, which play an important role in heart and brain health,Chia seeds. Although they are small in size, chia seeds are rich in several nutrients.

How fat is formed?

Researchers have found that most fat cells arise from cells in the walls of blood vessels in fat tissue. This insight may lead to new approaches to prevent and treat obesity. White adipose, or fat, tissue plays a role in regulating our metabolism, reproduction and life spans.

Functions of fat.

Fat helps to  give us body energy,depot for energy storage, protects our organs, supports cell growth, keeps cholesterol and blood pressure under control, and helps  body absorb vital nutrients.Triglycerides, cholesterol and other essential fatty acids—the scientific term for fats the body can't make on its own—store energy, insulate us and protect our vital organs. They act as messengers, helping proteins do their jobs

Fatty acid have also health benefit Research shows that omega-3 fatty acids can improve your cardiovascular health. Most of this research involves EPA + DHA, but ALA can also help improve your health. Benefits of including omega-3 fatty acids in your diet include: Reduced risk of cardiovascular disease

Healthy fatty acids?

Good sources of omega-3 fatty acids include fatty fish such as salmon, mackerel, and sardines, flaxseeds, walnuts, canola oil, and un-hydrogenated soybean oil. Foods rich in linoleic acid and other omega-6 fatty acids include vegetable oils such as safflower, soybean, sunflower, walnut, and corn oils. but Your body needs healthy fats for energy and other functions. But too much saturated fat can cause cholesterol to build up in your arteries (blood vessels). Saturated fats raise your LDL (bad) cholesterol. High LDL cholesterol increases your risk for heart disease and stroke

                                                     Bad fat

Two types of fats — saturated fat and trans fat — have been identified as potentially harmful to your health. Less than 7% of your total daily calories should come from saturated fats. Less than 1% should come from trans fats. In a 2,000-calorie daily diet, that's less than 15 grams of saturated fat and less than 2 grams of trans fat. 

Most of the foods that contain these types of fats are solid at room temperature, such as: 

                 Butter.
                Margarine.
                Shortening.
                Beef or pork fat.
