Fat

The human body needs healthy diets to maintain its health, healthy diets that contain all kinds of nutrients such as calcium, fiber and fats. Balance and healthy diets are complete only when they contain the required amount of fats, although the body needs very little fat. The human body needs the fatty acids to generate energy, it gets from fats to maintain its health, because fats are sources of getting energy. remember that human body unable to produce fats by itself. The diet we take for vitamins does not resolve the body without the help of fatty acids. These vitamins are fat-soluble. Vitamins will not dissolve in the body if there are no or less fats in the body. Therefore, eating foods rich in fats are essential for human health. Any type of fats that cannot be used by the human body is converted into fats.
Note that unused carbohydrates and proteins are converted to fats if they are used or in excess in the body.
All types of fats are big sources of getting energy because all types are high in energy.

Fat Definition
Fats are one of the essential nutrients needed to digest food, also called triglycerides. Fats are a big source of energy, and provide energy to the whole body cells specially to eukaryotes, it is also a energy provider itself as a food source.
Fats are rich in highest energy, While these combine with other nutrients to provide energy to the body, fats have a high ability to store energy within themselves. The chemicals in the energy contained in it are not wasted but remain stable. Whenever there is a shortage of nutrients in the body, the body uses energy from the safe treasury of fats.

Fat: saturated and unsaturated
dietary fats play important role in making humanm healthy. The persons who don,t take essential quantity of fats, their body may be very weak and their body may show symptoms of many diseases. Body cells are basic unit of human body, if the body cells are healthy the whole body is healthy as well. So, to maintain the body cells health the Dietary fat is essential for the body.
Difference types of hormones and signalling molecules production is due to fats. It is not onmy the great source of energy but also is a great storage of energy in the form of spare fays in the body.
We can devide the dietary fat into two categories,
Saturated Fats
unsaturated Fats
trans fats.

Both categories have same amount of calories but as the function is consern, they play difference role on the body health.
1st we should understand about dietary fats, its categories and their fuction as well. Then we have to keep balance between different dietary fats to maintain the good health and protect ourselves from health risks. Under we are going to explaine the details of dietary fats.
Saturated fats

There are many types of fats.
These types are based on different molecules, hydrogen molecules, number of bonds and formation of carbon bonds. According to the terms of chemistry, some types have only one bond, and some types have more than one bond. The amount of hydrogen molecules varies in some types of saturated fats. It is also common in the business market that fats are processed through hydrogen molecules in order to keep them at room temperature. These are all types of saturated fats. Due to the presence of hydrogen molecules and the lack of bonds, there is a lack of healthy utility in fats. This the reason that the saturated fays are called bad fats.
Although, it is a type of dietary fats but it is not a healthy fats like trans fat. Due to hydrogen molecules it become solid and remain solid at room temperature, so due to the being solid, it does not melt at body temperature. It remain solid in blood stream and can develop risk of high blood cholesterol and heart diseases as well.
Noted that all types of fats are made up of carbon, hydrogen, and oxygen molecules.

The chemical point of view, the saturated fat, remain solid at room temperature and it does not melt at body temperature. While, unsaturated fat remains liquid at room temperature. Mostly plants based oils are Unsaturated fat. Comparatively, the Unsaturated fat are healthy than saturated fat. Due to containing good fats and good cholesterol, it is helpful to prevent from heart diseases, so it is suggested to eat Unsaturated fat instead of saturated fat to maintain good health. Unsaturated fats are good fats.

Unsaturated fats contain a lot of high proportion of fatty acid molecules along with one double bond. All types of fats having double bond with fatty acids are healthy fats and all meals cooked in Unsaturated fats are healthy foods.

There are two main categories and two sub categories of unsaturated fats.
Monounsaturated fats
Polyunsaturated fats
Omega-3 fatty acids
Omega-6 fatty acids

Monounsaturated fats
All types of plants based fats are monounsaturated fats. These fats help to prevent from heart diseases, due to HDL (good cholesterol),
Sometimes, despite all precautions and efforts, a person eats foods that develop bad cholesterol levels in the body, which increases the amount of LDL cholesterol in the blood. When monounsaturated fats are used in most foods, the amount of HDLcholesterol in the body increases which helps in lowering the amount of LDL cholesterol. But keep in mind that eating monounsaturated fats too much don,t develop reduction of LDL cholesterol in the body.
Monounsaturated fats found in following:-

avocado
nuts
vegetable oils
canola
olive oil
Monounsaturated fats generally affect LDL cholesterol and help reduce LDL cholesterol level in the body. Through reduction of LDL cholesterol it can lower your risk of heart disease and stroke. To maintain the body cells membranes, this fats provide nutrients, who help to develop and maintain the body cells. The monounsaturated fats also provide contribution antioxidant vitaminand Vitamin E to the diets.
Monounsaturated fats generally affect LDL cholesterol and help reduce LDL cholesterol level in the body, whereas, Polyunsaturated fats play role in building the cell membrane and also manage the nerves covers. Polyunsaturated fats not only build up the body’s ability to fight against blood cloting and inflamation but also help in muscle movement.
Please note that human body unable to make the polyunsaturated fats by own ,so man has to provide polyunsaturated fat from diets to keep function of polyunsaturated fat, who is essevtial for body maintinance and development.

Chemistory point of view, polyunsaturated fat has two or more double bonds in its carbon chain.

There are two subtypes of polyunsaturated fats
Omega-3 fatty acids
Omega-6 fatty acids
Polyunsaturated fat are plant base fats and mostly found in vegetables such as sunflower, soybean, sesame, safflower and corn oils.
All type of seafoods are rich in polyunsaturated fats, this is the reason the Nutritionist suggest to eat seafoods to gain omega-3 and omega-6 fatty acids for the body.

Omega- 3s is a compound of verious essential types of fats. These fatty acids are subtypes of Polyunsaturated fats. This type of fats play key role in construction of that it is important for the body to eat the diet in wstructure of every cell wall of body and also help to build and maintain a healthy body. They are so important hich they are found in order to meet its needs. According to the nutritionist, it is a great source of energy to keep main body organs in function such as heart, lungs, blood vessels and immune system.
As human body unable to produce these types of fatty acids on its own, so to meet this need human has to eat diets who are rich in omega-3 fatty acids. Due to any reason, the person who do not eat much of these foods, hey can make up for it supplement who are rich in omega-3 such as fish oil or algal oil.

There are three types of omega-3s:-
ALA (alpha-linolenic acid)
DHA (docosahexaenoic acid)
EPA (eicosapentaenoic acid)
All these types are very important for helthy human body.
ALA (alpha-linolenic acid)
From fatty acids, the “Alpha-linolenic acid” is most essential for health, because our body need this fatty acids to body growth and also for development. Alpha-linolenic acid is usefull for heart and blood vessels health, specially for atherosclerosis and to keep the blood pressure normal.
ALA (alpha-linolenic acid) is found in
Walnuts and other nuts
vegetable oils such as flaxseed oil
canola oil
soybean oil
chia seeds,
hemp seeds
red meat
dairy products.

DHA (docosahexaenoic acid)
This type docosahexaenoic acid of omega-3 fatty acid are the most important omega-3 fatty acid for body growth. It play key role to structural component of human brain, the retina of your eyes, and numerous other body parts.
Our body produces very low amount of this type of omega 3″(docosahexaenoic acid)”, so to fulfil its deficiency nay have to get rest the amounts we need from food or supplements. It is better for us to include foods rich in docosahexaenoic acid in daily meals.
