![]() Of all the macronutrients, it has the highest thermic effect, meaning the digestive process to break down and absorb protein uses more calories than fat or carbohydrates. Consuming protein regulates hormones that are responsible for controlling fat storage, making it key for fat loss. Protein is especially important for gym-goers to recover and build lean mass. Protein breaks down into amino acids, which form the building blocks for our body to build and repair cells, muscles and organs. Higher order fats include seeds, nuts, fish, grass-fed meats, avocado, olive oil, lard, butter, coconut, palm oil, flaxseed oil, and olives.Įvery gram of fat contains 9 calories. These should be minimized, if not excluded, from your diet. Lower order fats include shortenings, pastries, fried foods, hydrogenated soybean, cottonseed and canola oil, and margarine. Fat quality and variety is very important, so we distinguish between lower and higher order fats. Eating fat is essential for hormone production, cell creation and absorption of vitamins. Fatĭietary fat does not equal body fat, and fat macros are an important part of a healthy diet. Understanding why each macro is important and what kinds of foods contain large amounts of them will help you put together meals that support your body composition, performance and health goals. Different foods contain varied ratios of the three macronutrients–fat, protein and carbohydrate. Replacing saturated fats and trans fats in the diet with unsaturated fats has been shown to decrease the risk of developing heart disease.Macronutrients supply the body with calories. Trans fats – found in commercially produced baked goods, snack foods, fast foods and some margarines.Unsaturated fat – found in foods like olive oil, avocados, nuts and canola oil (plant sources).Saturated fat – found in foods like meat, butter and cream (animal sources).provide foods with flavour and texture.assist with absorption of the fat-soluble vitamins A, D, E and K and carotenoids.supply fatty acids that the body needs but cannot make (such as omega-3).In addition to supplying energy, fats are needed to: It is recommended that 20–35% of our daily energy requirement should be supplied through the consumption of fats and oils. Why do we need fats?Īlthough fats have received a bad reputation in relation to heart disease and weight gain, some fat in the diet is essential for health and wellbeing. However, by eating a variety of plant sources, the essential amino acids can be supplied. Protein in the diet that comes from animal sources contains all of the essential amino acids needed, whereas plant sources of protein do not. The other amino acids can be synthesised by the liver if not provided by the diet. ![]() ![]() Eight of these amino acids are described as ‘essential’, which means that the food we eat must contain proteins capable of supplying them. As starting materials in the production of other compounds needed by the body.Īll the proteins in the body are made up of arrangements of up to 20 different amino acids.As ‘building blocks’ in the production of ‘new’ proteins needed for growth and repair of tissues, making essential hormones and enzymes and supporting immune function.The body can then use these amino acids in 3 main ways: The proteins we consume as part of our diet are broken down in the gut to amino acids. ![]() It is often referred to as ‘dietary fibre Why do we need proteins? Although unable to be used as an energy source, this type of carbohydrate plays a very important role in maintaining the health of the large intestine and assisting with the removal of body waste. For example, cellulose is a non-digestible carbohydrate present in fruits and vegetables. Not all of the carbohydrates found in foods are digestible.
