Nutrients
- Essential fatty acids have anti-inflammatory properties and play an important role in the regulation of cholesterol levels, they are precursors of prostaglandins, which are hormone-like substances that produce various metabolic effects in the body
- Phospholipids are required to be used around cell membranes to ensure their integrity and proper function
- Vitamin A is an essential nutrient beneficial for its antioxidant properties and protective effect on the immune system
Types of Fats
There are four types of fats that occur naturally in foods, of which the unsaturated ones are the most healthiest:
- saturated fats - found in animal foods and are known to be a major factor in causing high blood cholesterol levels of the bad (LDL) cholesterol - sources include red meat, poultry, butter and whole milk
- monounsaturated fats - a good fat, which helps to lower bad (LDL) blood cholesterol levels - sources include avocado and most nuts
- polyunsaturated fats - a good fat, which helps to lower bad (LDL) blood cholesterol levels - sources include vegetable oils
- unsaturated fats - found in plant foods and some fish (salmon, tuna) and help to lower blood cholesterol levels of the bad (LDL) cholesterol and is the best fat type for health - sources include plants and fish
Apart from the naturally-occuring fats, there are also some fats which are artifically created and added to most processed and snack foods and are very unhealthy:
- hydrogenated fats - oils that have been hardened (margarines) with the addition of hydrogen - this makes the oil solid at room temperature. Manufacturers use this type of oil as it has a longer storage time than just plain oil. These oils are complete unhealthy as they make trans fats
- partially hydrogenated fats - oils that have been partially hardened (biscuits) with the addition of some hydrogen - this makes the oil more solid at room temperature. Manufacturers use this type of oil as it has a longer storage time than just plain oil. These oils are complete unhealthy as they make trans fats
- trans fats - form when oils are hardened (hydrogenation) or partially hardened (partial hydrogenation) and causes bad (LDL) blood cholesterol levels to rise and raises the risk of heart disease
Amount of Dietary Fat Recommended
- Dietary fat should consist of no more than 30% of total daily calorie intake - which is about 50g-60g of fat for a sedentary person on 7500kJ (1800 calories) a day
Amount of Dietary Protein Recommended
- Dietary protein should consist of no more than 0.75g per kilogram body weight of total daily calorie intake - women who are pregnant should add another 6g of protein and lactating women should add 16-12g of protein per day
Amount of Dietary Carbohydrate Recommended
- Dietary carbohydrate should consist of 45%-65% of total daily calorie intake - it is recommended that these come from unrefined sources with a lower glycemic index
