Fat is an essential part of our diet and nutrition, we cannot live without it. Fat is a natural oily substance occurring in animal bodies. Fats especially when deposited as a layer under the skin or around certain organs. fats are liquid at room temperature while others are solid. We refer to those which are liquid at ambient temperature like oils.
Fats belong to a group of substances called lipids, and come in liquid or solid form. All fats are combinations of saturated and unsaturated fatty acids.
Types of fats:
1. Saturated fats
In this, each molecule of fat is covered in hydrogen atoms. Saturated fats increase health risks if you consume too much over a long period of time. saturated fats will eventually raise cholesterol levels.
2. Monounsaturated fats
monounsaturated fats are neutral , they are neither good nor bad for you. Many health professionals, they reduce a person’s risk of developing heart disease.
3. Polyunsaturated fats
polyunsaturated fat is good for our health, especially those from fish, known as the Omega-3 polyunsaturated fatty acids. polyunsaturated fatty acids protect us from heart disease as they lower blood cholesterol levels.
Trans fats are created in an industrial process that adds hydrogen to liquid vegetable oils to make them more solid. Trans fats are not essential for human life and they most certainly do not promote good health. It is also known as partially hydrogenated oils.
Fat is Good!
Fat provides a cushion to help protect our vital organs without fat our organs would be more prone to damage.
Fat is a concentrated source of energy ,1 gram of fat contains 9 calories, much more than a gram of protein or carbohydrate which both contain 4 calories per gram.
Fat makes food taste better. Hot buttered crumpets, double cream on trifle, gravy made from dripping.
Fat is Bad
Fat can cushion and protect our internal organs, however too much cushioning means more bulk and weight is increased.
Our bodies have evolved to cope with seasonal availability of food storing fat when food is plentiful and burning it off when food is scarce.
Eating too much saturated fat is one of the major risk factors for heart disease. A diet high in saturated fat causes a soft, waxy substance called cholesterol to build up in the arteries.
What is a Healthy Fats.
The monounsaturated and polyunsaturated fats are what most people refer to as healty fats.
Yet humans have likely consumed unprocessed forms of saturated fats (such as organ meats from wild game, blubber from seals and whales, milk, or coconuts) for their entire existence.
Are You fathead literally
Fat we consume is digested and either used for energy, stored in adipose (fat) tissue, or incorporated into other body tissues and organs. Many of our body tissues are lipid based, including our brains and the fatty sheath that insulates our nervous systems. Our cell membranes are made of phospholipids Thus, the fat we consume literally becomes part of our cells. It can powerfully influence how our cells communicate and interact.
