Healthy eating

Eating a well-balanced diet can reduce your risk of various diseases and help you to keep to a healthy weight. It’s important to eat a good diet no matter what age you are – there’s never a bad time to make some changes.

To help make healthy eating easier, we’ve explained how much you need of each food group along with some tips and advice to keep things on track. We’ve also got some tasty recipes to share with you too.

  • Why is healthy eating important? Why is healthy eating important?

    There's good evidence that eating a healthy diet can reduce your risk of:

    • obesity 
    • diabetes 
    • heart disease 
    • stroke 
    • osteoporosis 
    • some types of cancer

    Eat the right proportion of foods from the major groups in the image below to give your body all it needs to stay healthy.

    An image showing the recommended balance of the five major food groups

    So how much should each type of food make up in your daily diet? Guidelines recommend the following.

    Food group Amount per day
    Starchy foods 33 percent
    Fruit and vegetables 33 percent
    Milk and dairy foods 15 percent
    Non-dairy protein 12 percent
    Foods high in sugar and/or fat 5 to 8 percent

  • Starchy foods Starchy foods

    An image showing slices of bread

    Starchy foods contain carbohydrates, which release energy slowly throughout the day. These should be your main source of energy so it's a good idea to include them with every meal. They will fill you up so you're less likely to feel hungry and snack during the day.

    Here are some examples of starchy foods and a suggested serving:

    • two wheat biscuits or 50g of muesli (with no added sugar) 
    • two slices of medium sliced bread 
    • one medium (about 180g) baked potato or five boiled new potatoes 
    • five tablespoons of cooked rice, couscous, bulgur wheat or quinoa 
    • 75g dry spaghetti 
    • half a 10 inch thin-crust pizza

    Tip: Choose wholegrain or wholemeal varieties where possible, and brown rice, as these are particularly high in fibre.

  • Fruit and vegetables Fruit and vegetables

    An image showing a kiwi fruit

    Eat at least five portions of fruit and vegetables each day. One portion of fruit or vegetables is 80g. This is equivalent to:

    • one apple, banana, pear, orange, grapefruit or avocado
    • two kiwi fruits (or a similar sized fruit)
    • one slice of a large fruit like melon or pineapple
    • three heaped tablespoons of fruit salad or stewed fruit
    • one heaped tablespoon of dried fruit (such as raisins and apricots)
    • a glass (150ml) of fruit juice
    • a cup of grapes, cherries or berries
    • three heaped tablespoons of vegetables
    • a dessert bowl of salad

    Tip: Your five portions don't all have to be fresh – dried, frozen, tinned, and juiced fruit and vegetables count too. Remember though that a glass of fruit juice only counts as one portion – no matter how many glasses you drink. This is because juicing fruit removes most of the fibre from the fruit. They also contain a lot of sugar.

  • Milk and other dairy foods Milk and other dairy foods

    Milk and dairy products, such as cheese and yoghurt, are important sources of protein, calcium and vitamins. Eat moderate amounts of these – two to three portions of dairy foods a day will provide you with all the calcium you need. 

    One portion is equivalent to:

    • 150g pot of yoghurt
    • 30g of cheese
    • 200ml of milk

    If you're vegan or lactose intolerant you will need to find other sources of calcium, as well as vitamin B12, which is in dairy food. Look out for fortified foods such as:

    • yeast extract
    • calcium-enriched soya milk, yoghurts and desserts
    • breakfast cereals
    • calcium-enriched rice drinks and oat drinks

    Tip: Check the labels and choose lower-fat options, such as semi-skimmed or skimmed milk. Or eat mature varieties of cheese so you max out on the flavour and eat less.

  • Non-dairy sources of protein Non-dairy sources of protein

    Meat, fish, beans, nuts, pulses, eggs and nuts are all important non-dairy sources of protein. Proteins give you energy and are essential to grow and repair tissues in your body.

    Aim to eat two portions of fish a week (one portion is about 140g). Make one of these portions an oily fish, such as mackerel, salmon or pilchards. Oily fish is rich in long-chain, omega-3 fatty acids, which may help prevent heart disease, although more research is needed to prove this.

    Limit the amount of processed meat you eat (such as sausages and beef burgers) as these foods often contain lots of fat and salt. They may also increase your risk of bowel cancer. Don't eat more than 70g a day. This is equivalent to:

    • a small steak (the size of a pack of cards)
    • three rashers of bacon or ham
    • a quarter-pounder beef burger

    For more information, see our article Red meat, processed meat and bowel cancer risk.

    An image showing beans and pulsesIf you're vegetarian or vegan, make sure you eat plenty of beans, nuts and pulses to get the protein you need. Aim to eat three heaped tablespoons (80g) of beans and pulses (such as kidney beans, chickpeas and lentils) a day. Nuts and seeds contain healthy polyunsaturated and monounsaturated fats as well as protein. Peanuts, almonds and cashews are particularly good protein sources. But don't eat too many because they are also high in calories – a small handful is all you need.

    Tip: Some types of meat are high in fat, so always cut off any extra fat and skin. Grill, bake or poach meat and fish rather than fry it.

  • Foods high in fat and sugar Foods high in fat and sugar


    Fats are a really concentrated source of energy and they also have other roles, such as helping to transport essential vitamins around your body. It's an important part of your diet but you don’t need very much – most of us need to eat less. The type of fat you eat is also important. 

    Saturated fat 

    Saturated fat can raise 'bad' cholesterol levels and increase your risk of heart disease. Men should have no more than 30g a day and women shouldn’t have more than 20g. Sources of saturated fat include: 

    • fatty cuts of meat
    • processed meats, such as sausages and bacon
    • butter
    • cheese
    • cream
    • crisps
    • chocolate, biscuits, cakes and pastries
    • palm oil
    • coconut oil
    • cream 

    An image showing an avocadoUnsaturated fats 

    polyunsaturated (omega-3 and omega-6) fats can help to lower your level of 'bad' cholesterol. Sources include:

    • omega-3 fats like oily fish 
    • omega-6 like vegetable oils, such as rapeseed, corn, sunflower oil, and nuts such as walnuts 

    Mono-unsaturated can help to maintain levels of 'good' cholesterol while reducing levels of 'bad' cholesterol. Sources include olive oil, rapeseed oil, avocados, nuts such as almonds, brazils and peanuts. 

    Men should have 65 g of unsaturated fats a day and women should 50g a day. 

    Tip: Replace foods that are high in saturated (bad) fats, such as butter, pastries and cheese with foods that are rich in unsaturated (good) fats. These are found in avocado and olive oil, for example. 


    As with fat, most of us are currently eating too much sugar. It's added to a range of tempting foods such as sweets, cakes, biscuits, chocolates, fizzy drinks, and fruit juices, as well as some alcoholic drinks. These are called free sugars. If you eat a lot of these, they can make you gain weight as well as put you at risk of tooth decay. Added sugar isn't necessary for a healthy diet. Guidelines recommend that you don’t eat more than 30g of free sugars a day – this is around the same as seven sugar cubes. 

    A range of foods contain natural sugar; examples are fresh fruit, peas, and sweetcorn. These also contain a range of other nutrients such as fibre and vitamins, so they are better for you than products with added sugar. Aim to satisfy your sweet tooth with these natural sugars rather than added ones. Tip: If you have the occasional treat, try to have a small portion – try individually wrapped cakes so you aren't tempted to have another slice. 

    Fat versus sugar 

    Many of us are conscious about the link between the amount of fatty food we eat and the amount that ends up on our hips. Yet in our eagerness to cut down on fat, it's very easy to up the amount of sugar we eat. Low-fat foods can often be pumped full of sugar so they won't help you on that quest to lose weight. 

    Singling out one nutrient is a bad idea and most of us should cut down on both fat and sugar anyway. A healthy diet is all about balance. If you eat the right balance of foods from the five major food groups and stick to sensible portion sizes, you're doing the right thing.

  • Fibre Fibre

    Fibre is another element of a healthy diet and there are two types. 

    • Insoluble fibre passes through your digestive system undigested and bulks up your faeces so they move through your digestive tract more quickly. This can help to prevent various bowel problems, such as constipation and diverticular disease. 
    • Soluble fibre is broken down by bacteria in your large bowel. It can help to control your cholesterol levels, which in turn reduces your risk of heart disease. 

    Aim to eat sources of soluble and insoluble fibre as they will both benefit your health but in different ways. 

    Soluble fibre is in: 

    • grains such as oats, barley and rye 
    • fruit, such as pears and plums 
    • beans and pulses, such as lentils and chickpeas 
    • root vegetables, such as carrots and potatoes 

    Insoluble fibre is in: 

    • high-fibre breakfast cereals 
    • wholemeal bread, pasta, and brown rice 
    • vegetables, nuts and seeds 

    Tip: Leave the skin on vegetables because you will get more fibre from them. Potato wedges are a tasty option, as are carrots sticks with hummus.
