NUTRITION SHEET Saturated fats Red meats, diary products, coconut and palm oils typically contain relatively high amounts of saturated fats. The NHS along with the World Health Association advise of the risk between saturated fat and heart disease. For many years the message has been that saturated fat consumption should be kept to a minimum. More recently some commentators have started to suggest that some saturated fat is a good thing. See for example: http://fourhourworkweek.com/2009/06/06/saturated-fat/ The recommended daily amount of saturated fat for men is no more than 30g and 20g for women. Some moderate consumption rather than attempting to eliminate is perhaps the answer. Unsaturated fats These are commonly talked about in terms of monounsaturated fats and polyunsaturated fats. Both categories are considered good fats. Monounsaturated fats are found in avocados, olive oil and many plants, whilst polyunsaturated fats are found in fish, walnuts and some seeds. Polyunsaturated fats are the ones that include both omega 3 and omega 6 fatty acids). The general recommendation appears to be that we should consume 20 to 35% of our calorie intake from unsaturated fats, with the majority coming from monounsaturated fats. Trans Fats (also known as partially hydrogenated oil) These exist in very small amounts naturally, but they are created in quantity by an industrial process that adds hydrogen to vegetable fats. The process creates an oil that gives foods a longer shelf life because it does not spoil as easy as it would if it were untreated. The fat has been shown to reduce good cholesterol, increase bad cholesterol and increase the risk of heart disease. The scientists appear to agree that this oil should be avoided. Low fat products If you are tempted to pick a brand that’s marked “low fat” think twice by taking a closer look at the ingredients. If fat has been stripped out it is likely to have been replaced by increased amounts of added salt or sugar. Salt Excess salt has been shown to increase blood pressure which in turn increases the risk of heart disease and a stroke. The recommended daily amount of salt is 6 grams. Sugar Increasingly high sugar intake is being held out as being particularly damaging. In excess sugar plays havoc with blood sugar levels and apparently negatively affects the immune system. The current recommended daily amount is 70g for men and 50g for women, although the World Health Organisation has a longer term aim to halve this amount. Recommended daily intake is based on total sugar consumption from all sources, not just added sugar. This is important because sugar exists in most foods - for instance two cups of broccoli contain 5 grams of sugar. It is not just total sugar intake that matters, but how much you consume at any one time. Insulin tends to react to particularly sugary food by over compensating. This can result in your blood sugar dropping too low, leaving you feeling fatigued and craving more sugar. Fibre acts to flatten out the sugar load on the system. Avoid concentrated fruit juices. Not only are they high in sugar, but generally the fibre has also been taken out.

Carb’s are therefore essential, but picking where you get your carb’s from and ensuring you do not consume too many is key. The best sources of carb’s are accepted as being those that release their energy into the body slowly. The list of so good carb’s includes nuts, seeds, grains and most vegetables, The carb’s to avoid are those containing refined sugars. It seems to be recognised that eating protein at the same time as eating carb’s is best. Ideal daily intake depends on the person and their activity levels. Protein Those wanting to increase muscle mass will need more protein than they would otherwise. It is however important not to overdo protein intake. Excess protein is turned to fat is not good for the kidneys. As a rule of thumb a daily protein intake of 0.8g per Kilo of bodyweight is considered appropriate for the normal person and it is generally understood that the body cannot digest much more than 25g of protein at any one time. The quality of the protein is also important. The body needs whole proteins. Meat, fish and eggs make up whole proteins, however combinations of other proteins can be eaten together to make up whole proteins ie beans with diary products or grains. Consuming protein regular and often is key, not least because amino acids that make up protein play a vital part in detoxifying the body. Hydration Your body is nearly two-thirds water so it is really important you consume enough water to stay hydrated and healthy. The recommended daily intake is 2 litres for men and 1.6 litres for women, which is on top of the water that comes from fluid within the food we eat. Even a small amount of dehydration can significantly affect both your physical and mental performance. Drink before and after exercise and ideally during. Snacking Your body can go into fat storing mode if your blood sugar level goes too high or too low - snack on the right things between meals is therefore an important part of eating well.
