Fat-friend or enemy?
Many people who wish to lose weight start their âdietâ by removing all the possible fat from it. However, fat is an essential nutrient for good health. There are different types of fats, and some are healthier than others. To help make sure you stay healthy, itâs best to choose mainly healthy fats, in moderate amounts.
To give you a brief introduction to the fat there are three types of them â unsaturated, saturated and trans fats.
Saturated fats
Saturated fats arenât so healthy, and eating a big amounts of saturated fat is linked with high blood cholesterol levels, which is a risk factor for heart disease. These fats are solid at room temperature and are found in:
Animal-based products:
⢠Meat â such as fatty cuts of beef, pork and lamb, processed meats like salami, and chicken (especially chicken skin).
⢠Dairy foods â such as butter, cream, ice-cream, regular-fat milk, custard and cheese
Some plant-derived products:
⢠Palm oil
⢠Coconut oil, milk and cream
⢠Cooking margarine.
Saturated fats are also found in processed foods such as:
⢠Fatty snack foods
⢠Deep fried take away foods e.g. hot chips, chicken nuggets, spring rolls, battered/crumbed fish
⢠Packaged cakes and biscuits
⢠Pastries and pies.
Unsaturated fats
Unsaturated fats are healthy fats and are an important part of a healthy diet. These fats help reduce the risk of heart disease and lower cholesterol levels when they replace saturated fats.
There are two main types of unsaturated fats: polyunsaturated fats and monounsaturated fats.
Polyunsaturated fats:
⢠Omega-3 fats which are found in oily fish such as salmon, sardines and anchovies as well as walnuts, canola oil, soy products, flaxseeds and omega-3 enriched eggs.
⢠Omega-6 fats which are found in some oils such as safflower and soybean oil, along with some nuts, including brazil nuts.
Monounsaturated fats:
⢠Found in olive and canola oil, avocados and some nuts, such as cashews and almonds.
Trans fats
Trans fats are unsaturated fats that have been processed, and behave like saturated fats inside the body. Trans fats also naturally occur in very small amounts in animal products (eg. dairy, beef and lamb products) due to the way that some animals digest their food. Consumption of manufactured trans fats increases the level of bad cholesterol and decreases the level of good cholesterol in the body, posing a major risk to heart health. It is important to lower the amounts of trans fats you eat to help improve your health and lower the risk of developing heart disease.
Trans fats are found in many processed foods such as deep fried foods, some takeaway meals, commercially baked goods like pies, pastries, cakes and biscuits. Spreads and margarines can also contain trans fats, . When buying any of the products, check the labels for trans fats which may be described as âhydrogenatedâ or âpartially hydrogenated vegetable fats/oilsâ.
