-Nutrients perform different functions in the body.
-The body needs different amounts of each nutrient. Specific figures (Dietary Reference Values) are published by the government.
-Healthy eating means selecting foods that will provide the nutrients you need.
-Measured in kilocalories (kcal) or kilojoules (kj).
-Provided by carbohydrates, fat, protein and alcohol.
-Balance the energy input from food with the energy output through activity – this helps to control body weight.
-A very concentrated source of energy – fat contains more than twice as much energy as sugar or starch.
-Should provide 30 – 35% of energy.
-Two types: saturated and unsaturated.
-Unsaturated fat is present in oily fish and foods from plants (oils, nuts and seeds).
-Unsaturated fat reduces the cholesterol level in the body.
-Two types: monounsaturated and polyunsaturated.
-Present in foods from animal sources (meat, milk, butter and cheese).
-Unhealthy as it pushes up blood cholesterol.
-Switch to foods containing unsaturated fat – use oil instead of butter, eat oily fish and white meat.
PERCENTAGE OF FAT IN SOME FOODS
FATS THAT ARE MOSTLY SATURATED
-Lard, suet, dripping
-Creamed coconut and coconut oil
-Palm oil and palm kernel oil
-Full-fat milk and diary fat
Rapeseed oil (canola)
FATS THAT ARE MOSTLY MONOUNSATURATED
-Sunflower oil and spread
FATS THAT ARE MOSTLY POLYUNSATURATED
MAIN SOURCES OF FAT IN THE DIET
-Two types: starches and sugars.
-Starches occur in bread, cereal, rice, pasta and potatoes.
-Starches should provide about 50% of energy.
-Starchy foods also contain some protein, vitamins, minerals and fibre.
HOW MUCH CARBOHYDRATE SHOULD
WE TAKE IN OUR DIETS?
A diet high in carbohydrates (especially unrefined) is recommended.
HOW MUCH CARBOHYDRATE SHOULD
WE TAKE IN OUR DIETS?
-Sugars occur naturally in fruit and honey. They are added to many manufactured foods.
-Tooth plaque contains bacteria which use sugar to create acid, causing tooth decay (more than half of UK teenagers suffer).
-Need to cut down on sugars.
-The roughage in plant foods – wholegrain cereals, pulses, fruit, vegetables and nuts.
-Good for the digestive system.
-Aim to eat about 30 g per day.
-Most people only eat about 20 g per day.
MAIN SOURCES OF CARBOHYDRATE IN THE DIET
The ‘body-building’ nutrient found in animal and vegetable foods, such as meat, fish, cheese, eggs, cereals, pulses and nuts.
-Adults need 35 – 50 g per day. That could be provided by 100 g of chicken or 200 g of baked beans and a yoghurt.
MAIN SOURCES OF PROTEIN IN THE DIET
-Needed in minute amounts for many bodily processes.
-Obtained from food.
-The government’s Dietary Reference Values include amounts for nine vitamins and eleven minerals.
VITAMINS AND MINERALS
-Found in foods of animal origin.
-The body can make vitamin A from carotene, which is found in orange juice and some fruit and vegetables, such as carrots, sweet potatoes and apricots.
-Several important functions in the body.
-Help release energy from food.
-Found in dairy products (especially vitamin B2, riboflavin) and protein-rich foods.
Found in milk and dairy products.
-Needed for healthy bones and teeth.
MAIN SOURCES OF CALCIUM IN THE DIET
VIDEO ON HEALTHY DIETS
(dynamic-learning level 2)
-Sodium is used to maintain the water balance in the body. High intakes can raise blood pressure, increasing the risk of stroke and heart disease.
-Salt is added to many manufactured foods, especially snacks.
-Aim for about 4 g of salt per day. (The UK average is estimated at 8 g!)
The amount of salt should be stated on food labels so that total intake can be calculated.
-Reduces obesity: Nearly 24 million adults in the UK are overweight or obese.
-Prevents illness: Poor diet is linked to illness. It may be a cause of one third of all cancers.
BENEFITS OF HEALTHIER EATING
Diet can be linked to:
high blood pressure
-Food, nutrition and exercise are crucial to our health and well-being.
Making the right choices of
food and drink, as well as
taking regular exercise, can
protect us against serious
RECAP: WHY IS HEALTHY EATING IMPORTANT?
RECAP: WHY IS HEALTHY EATING IMPORTANT?
-There are no good and bad foods.
-The important thing is to eat a balanced diet.
-The Food Standards Agency provides advice. Go to: www.food.gov.uk
A HEATHY DIET
-Plenty of starchy foods – breads, cereals, pasta, potatoes, rice.
-Five portions (about 80 g each) of fruit and vegetables.
-Two or three portions each of dairy foods and meat.
Very small amounts of fats and sugars.
A BALANCED DIET EVERY DAY
Five portions of fruit and vegetables a day
THE GOVERNMENT INITIATIVE '5 A DAY'
IN TERMS OF A BALANCED DIET,
IS THIS HEALTHY FOOD?
-Two portions of fish per week. Include one of oily fish as they contain Omega 3 oil which can help thin the blood and protect the heart.
‘-Five a day’ of fruit and vegetables. This should only include:
one portion of beans or pulses
one portion of fruit juice, however much you drink.
A BALANCED DIET IN DETAIL
DEFINITION: A BALANCED DIET IS THE FOOD REQUIRED TO MAINTAIN GOOD HEALTH
THE EATWELL PLATE
THE RECOMMENDED BALANCE
-Try to balance it over a few days – not necessarily at every meal.
-Include bigger portions of starchy foods, vegetables and fruit.
-Small changes to favourite meals can make a big difference.
-There’s still scope for the occasional treat!
A BALANCED DIET IN PRACTICE
CATERING FOR HEALTHY DIETS
-Chefs can play a vital role in providing healthy, well-balanced meals.
-Make small changes to recipes and methods. Be adventurous and make healthy eating exciting.
-Many customers are looking for healthy options and will return to establishments providing ‘healthy’ food.
-In residential establishments, good, balanced nutritional meals are especially important.
-School caterers have to provide meals that meet minimum nutritional standards.
THE ROLE OF THE CATERER
-Increase quantities of starchy foods – base meals on them.
-Increase fibre quantity of meals where practical.
-Reduce fat in traditional recipes.
-Use unsaturated fat instead of saturated.
-Use moderate amounts of sugar and salt.
Increase quantities of fruit and vegetables:
-Add more to stir-fries and casseroles.
-Use as starters (asparagus, melon, vegetable soup) and desserts.
-Offer as snacks, fresh or dried.
-Offer colourful salads with meals.
-Offer fresh juices and smoothies.
To retain the vitamins:
-Steam, microwave or stir-fry in a little oil if possible.
-Peel thinly using a peeler.
-Store and cook for as short a time as possible.
-If boiling, use less water, bring it to the boil first and do not leave food sitting in the water for long periods.
PREPARING FRUIT AND VEGETABLES
-Healthy rice dishes include boiled or steamed rice, paella, risotto and pilaff.
-Try using brown rice in rice dishes.
-Don’t use too much oil with pasta.
-Use thick slices of healthy breads – wholegrain, granary, pitta – and use low-fat sandwich fillings.
USING STARCHY FOODS
-These include wholemeal and wholegrain breads, pitta, chapatti, brown rice, wholewheat pasta and wholegrain breakfast cereals.
-They contain more fibre and other nutrients than refined, starchy foods.
-They take longer to digest so we feel full for longer.
-Don’t peel potatoes, yams or cassava too deeply.
-Leave skins on potatoes if possible, for fibre.
-Bake or boil them if possible, as this is healthier than frying.
-Less healthy than baking or boiling.
-Large pieces and straight chips fried at a high temperature (155–255°C) will absorb less fat.
-Pre-blanch chips in a steamer.
-Make healthier chips by steaming, brushing with oil and then baking.
Move from saturated to unsaturated fat by:
-using olive oil instead of butter
-using ‘white’ shortening for pastry
-using coconut milk instead of creamed coconut
Reduce fat content by:
-grilling, steaming, stir-frying or baking
-using puréed vegetables instead of roux thickenings
-skimming fat off sauces
-dry frying or dry roasting spices
-using non-stick frying pans so less fat is needed.
Reduce fat content by:
-using a rack or trivet when roasting
-making sure the oil is hot enough when frying
-offering dressings separately, instead of dressing salads
-encouraging suppliers to offer low-fat alternatives.
Cut down on the fat content of meat dishes by:
-using lean meat
-trimming fat from meat, and fat and skin from poultry
-racking and draining
-using less meat and more pulses, vegetables and starchy foods
-using alternatives like tofu or Quorn.
What is this method of Cookery called?
THE HEALTHIEST COOKING METHOD IS
STEAMING. A GOOD METHOD FOR RESTAURANT FOOD IS 'EN PAPILLOTE'
-Pulses are low in fat and rich in protein, carbohydrate and fibre.
-They count as a portion of fruit and vegetables.
-They provide an important source of nutrients for vegetarians and a tasty alternative for meat-eaters.
-Add pulses to soups and stews.
-Use lower-fat versions of milk and cheese as there is no loss of calcium.
-Use a strong-tasting cheese for flavouring, but use less of it.
-Grate hard cheese for sandwiches and salads, using less.
-Replace cooking cream with yoghurt, arrowroot or cornflour to prevent separation.
-Use yoghurt in mayonnaise.
USING DAIRY PRODUCTS
-Offer some healthy choices such as sorbet and fresh fruit.
-For sponges use the fatless whisked sponge method instead of the creaming method.
-Serve single cream separately and offer alternatives such as fromage frais.
-Use fruit fillings instead of cream.
Many fizzy drinks have added sugar or preservatives and some have stimulants.
Healthier alternatives include:
-fruit juices and smoothies
