The Fat Issue
It’s true that our diet should include a little fat. It helps us absorb certain vitamins, it provides energy and some essential fatty acids. But it can be hard not to eat too much fatty food, with the inevitable flabby results. The nutrition labels on food packages can tell you a lot about the fat content of foods – as long as you know how to interpret them. Basically, we should be eating less saturated or trans fats, and replacing them with unsaturated fats. We should also be eating omega 3 fatty acids. If you remain confused, read on for an interpretation!
Saturated fats can increase a substance called cholesterol in the blood, and this can lead to heart disease. Foods high in saturated fats include meat products such as sausages and pies, hard cheese, butter, pastry, cakes, biscuits, cream (including crème fraiche) and coconut oil.
Trans fats also increase cholesterol, and may be worse than saturated fats. They can be formed during hydrogenation, so check on the ingredients label whether the food contains hydrogenated vegetable oil. (Hydrogenation converts liquid vegetable oil into solid fat, to make spreads, for instance.) Trans fats can appear in biscuits, cakes, pastry and margarine.
Unsaturated fats, including polyunsaturated and monounsaturated fats, are the healthier option because they don’t have the same effect on cholesterol levels but can provide your bodily fat needs. Foods high in unsaturated fat include oily fish, avocados, nuts and seeds; sunflower, rapeseed, olive and other vegetable oils.
Omega 3 fatty acids can help to protect you against heart disease. The best source is oily fish such as salmon, trout, mackerel, herring, sardines, pilchards, kippers, eel, whitebait, fresh tuna and anchovies. Aim for a portion of oily fish every week.
Look at the nutrition label to find out how much fat the food contains per 100g. Many labels also helpfully tell you how much of that fat is saturated. High-fat foods may contain 20g or more per 100g, and 5g of saturated fat per 100g. Low-fat food might contain 3g of total fat or 1g of saturated fat per 100g.
Foods labelled “Light” or “Lite” or even “Low Fat” contain less fat – but less than what? The nutrition label alone will tell you exactly how much fat per 100g this really means.
