Fats are a common component of many foods. Fats are also called ‘Fatty acid’ or ‘lipids. Fats in our body are made up of three molecules joined together. This three-molecule structure is called a “triglyceride’.

Fats are a common component of many foods. Fats are also called ‘Fatty acid’ or ‘lipids. 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.
Fats are a type of nutrient that we get from our food. It is essential to eat some fats, through it is also harmful eat too much.
The fats we eat give our body energy that it needs to work properly.
Functions of fats:

Energy Source: Fats are concentrated source of energy, providing more than twice the energy(calorie) per gram compared to carbohydrates and protein. They serve as a reserve energy source for the body.
Nutrient Absorption: Fats are necessary for the absorption of fat-soluble vitamins (A, D, E, and K). These vitamins are essential for various bodily functions, including bone health, vision, and immune system support.
Cell Membranes: Fats, particularly phospholipids, are integral components of cell membranes. They help maintain cell structure, regulate what enters and exit cells, and facilitate cellular communication.
Protection of Organs: Adipose tissue, which consists of stored fat, acts as a cushion and insultation, protecting vital organs and helping maintain body temperature.
Hormone Production: Fats are involved in the production of hormones. For example, cholesterol, a type of fat, is a precursor to steroid hormones like estrogen, pro progesterone, and testosterone.
Brain Health: The brain is composed of about 60% fat. Dietary fats, especially omega-3 fatty acids, are crucial for brain development, function, and cognitive health.
Skin and hair health: Fats help maintain healthy skin and hair. They contribute to moisture and elasticity in the skin.
Inflammation Regulation: Some fats, such as omega-3 fatty acids, have anti-inflammatory properties and can help reduce inflammation in the body.
Disadvantages of fat:

Weight gain: High-fat diets, especially those high in saturated and trans fats, can contribute to weight gain and obesity if calorie intake exceeds expenditure. Fat is calorie-dense, providing more calories per gram than carbohydrates or protein.
Cardiovascular Health: Excessive consumption of saturated and trans fats can raise levels of LDL (low-density lipoprotein) cholesterol, which is associated with an increased risk of heart disease. It can also contribute to the development of atherosclerosis, a condition in which arteries become clogged with fatty deposits.
Chronic Diseases: A diet high in unhealthy fats is linked to an increased risks of chronic health conditions, including heart disease, hypertension, type 2 diabetes, and certain cancers.
Digestive Issues: Very high-fat meals, particularly those high in saturated and trans fats, can lead to digestive discomfort, including indigestion and diarrhea, as fats can be harder to digest for some individuals.
Inflammation: Some types of fats, especially saturated fats, can promote inflammation in the body. Chronic inflammation is associated with a range of health issues, including autoimmune disease and certain chronic conditions.
Metabolic Syndrome: Excessive fat intake, particularly unhealthy fats, can contribute to metabolic syndrome, a cluster of conditions that increase the risk of heart disease, stroke, and type 2 diabetes. These conditions include high blood pressure, high blood sugar, excess abdominal fat, and abnormal cholesterol levels.
Liver Disease: High-fat diets can lead to non-alcoholic fatty liver disease (NAFLD), where excess fat accumulates in the liver, potentially leading to liver damage.
Weight-related Health Conditions: Excess body fat can increase the risk of various health conditions, such as sleep apnea, joint problems, and fertility issues.
Amount of fat consumption per day:
Men should have less than 30g of saturated fat per day
Women should have less than 20g of saturated fat per day
Children should have less trans fat and saturated fat per day
