Eat lots of fruit and veg
Most people know we should be eating more fruit and veg. But most of us still aren't eating enough.
Try to eat at least 5 portions of a variety of fruit and veg every day. It might be easier than you think.
You could try adding up your portions during the day.
For example, you could have:
a glass of juice and a sliced banana with your cereal at breakfast
a side salad at lunch
a pear as an afternoon snack
a portion of peas or other vegetables with your evening meal
You can choose from fresh, frozen, tinned, dried or juiced, but remember potatoes count as a starchy food, not as portions of fruit and veg.
Eat more fish
Most of us should be eating more fish - including a portion of oily fish each week. It's an excellent source of protein and contains many vitamins and minerals.
Aim for at least two portions of fish a week, including a portion of oily fish. You can choose from fresh, frozen or canned - but remember that canned and smoked fish can be high in salt.
What are oily fish?
Some fish are called oily fish because they are rich in certain types of fats, called omega 3 fatty acids, which can help keep our hearts healthy.
How much oily fish?
Although most of us should be eating more oily fish, women who might have a baby one day should have a maximum of 2 portions of oily fish a week (a portion is about 140g). And 4 is the recommended maximum number of portions for other adults.
Examples of oily fish
Salmon, mackerel, trout, herring, fresh tuna, sardines, pilchards, eel
Examples of white or non-oily fish
Cod, haddock, plaice, coley, tinned tuna, skate, hake
Shark, swordfish and marlin
Don't have more than one portion a week of these types of fish. This is because of the high levels of mercury in these fish.
Anyone who regularly eats a lot of fish should try and choose as wide a variety as possible.
For more information on fish and for advice - including recommended limits - for children, women who are pregnant, breastfeeding or trying for a baby, see the link below.
Cut down on saturated fat and sugar
Fats
To stay healthy we need some fat in our diets. What is important is the kind of fat we are eating. There are two main types of fat:
saturated fat - having too much can increase the amount of cholesterol in the blood, which increases the chance of developing heart disease
unsaturated fat - having unsaturated fat instead of saturated fat lowers blood cholesterol
Try to cut down on food that is high in saturated fat and have foods that are rich in unsaturated fat instead, such as vegetable oils (including sunflower, rapeseed and olive oil), oily fish, avocados, nuts and seeds.
Foods high in saturated fat
Try to eat these sorts of foods less often or in small amounts:
meat pies, sausages, meat with visible white fat
hard cheese
butter and lard
pastry
cakes and biscuits
cream, soured cream and crème fraîche
coconut oil, coconut cream or palm oil
For a healthy choice, use just a small amount of vegetable oil or a reduced-fat spread instead of butter, lard or ghee. And when you are having meat, try to choose lean cuts and cut off any visible fat.
How do I know if a food is high in fat?
Look at the label to see how much fat a food contains. Generally the label will say how many grams

of fat there are in 100g of the food.
Some foods also give a figure for saturated fat, or 'saturates'.
Use the following as a guide to work out if a food is high or low in fat.
Total fat - what's high and what's low?
High is more than 20g fat per 100g
Low is 3g fat or less per 100g
If the amount of fat per 100g is in between these figures, then that is a medium level of fat.
Saturated fat - what's high and what's low?
High is more than 5g saturates per 100g
Low is 1.5g saturates or less per 100g
If the amount of saturates per 100g is in between these figures, then that is a medium level of saturated fat.
Remember that the amount you eat of a particular food affects how much fat you will get from it.
Try to choose more foods that are low in fat and cut down on foods that are high in fat.
