These 8 practical tips cover the basics of healthy eating and can help you make healthier choices.
If you eat or drink more than your body needs, you'll put on weight because the energy you do not use is stored as fat. If you eat and drink too little, you'll lose weight.
You should also eat a wide range of foods to make sure you're getting a balanced diet and your body is receiving all the nutrients it needs.
It's recommended that men have around 2,500 calories a day (10,500 kilojoules). Women should have around 2,000 calories a day (8,400 kilojoules).
1. Base your meals on higher fibre starchy carbohydrates
Choose higher fibre or wholegrain varieties, such as wholewheat pasta, brown rice or potatoes with their skins on.
They contain more fibre than white or refined starchy carbohydrates and can help you feel full for longer.
Try to include at least 1 starchy food with each main meal. Some people think starchy foods are fattening, but gram for gram the carbohydrate they contain provides fewer than half the calories of fat.
2. Eat lots of fruit and veg
Getting your 5 A Day is easier than it sounds. Why not chop a banana over your breakfast cereal, or swap your usual mid-morning snack for a piece of fresh fruit?
A portion of fresh, canned or frozen fruit and vegetables is 80g. A portion of dried fruit (which should be kept to mealtimes) is 30g.
3. Eat more fish, including a portion of oily fish
Fish is a good source of protein and contains many vitamins and minerals.
Aim to eat at least 2 portions of fish a week, including at least 1 portion of oily fish.
Oily fish are high in omega-3 fats, which may help prevent heart disease. You can choose from fresh, frozen and canned, but remember that canned and smoked fish can be high in salt.
4. Cut down on saturated fat and sugar
Saturated fat
There are 2 main types of fat: saturated and unsaturated. Too much saturated fat can increase the amount of cholesterol in the blood, which increases your risk of developing heart disease.
On average, men should have no more than 30g of saturated fat a day. On average, women should have no more than 20g of saturated fat a day.
For a healthier choice, use a small amount of vegetable or olive oil, or reduced-fat spread instead of butter, lard or ghee.\
Sugar
Sugary foods and drinks are often high in energy (measured in kilojoules or calories), and if consumed too often can contribute to weight gain. They can also cause tooth decay, especially if eaten between meals.
Free sugars are any sugars added to foods or drinks, or found naturally in honey, syrups and unsweetened fruit juices and smoothies.
This is the type of sugar you should be cutting down on, rather than the sugar found in fruit and milk.
5. Eat less salt: no more than 6g a day for adults
People with high blood pressure are more likely to develop heart disease or have a stroke.
Even if you do not add salt to your food, you may still be eating too much.
About three-quarters of the salt you eat is already in the food when you buy it, such as breakfast cereals, soups, breads and sauces.
Use food labels to help you cut down. More than 1.5g of salt per 100g means the food is high in salt.
6. Get active and be a healthy weight
Being overweight or obese can lead to health conditions, such as type 2 diabetes, certain cancers, heart disease and stroke. Being underweight could also affect your health.
Most adults need to lose weight by eating fewer calories.
If you're trying to lose weight, aim to eat less and be more active. Eating a healthy, balanced diet can help you maintain a healthy weight.
Check whether you're a healthy weight by using the BMI healthy weight calculator.
Start the NHS weight loss plan, a 12-week weight loss guide that combines advice on healthier eating and physical activity.
7. Do not get thirsty
You need to drink plenty of fluids to stop you getting dehydrated. The government recommends drinking 6 to 8 glasses every day. This is in addition to the fluid you get from the food you eat.
All non-alcoholic drinks count, but water, lower fat milk and lower sugar drinks, including tea and coffee, are healthier choices.
Try to avoid sugary soft and fizzy drinks, as they're high in calories. They're also bad for your teeth.
Even unsweetened fruit juice and smoothies are high in free sugar.
8. Do not skip breakfast
Some people skip breakfast because they think it'll help them lose weight.
But a healthy breakfast high in fibre and low in fat, sugar and salt can form part of a balanced diet, and can help you get the nutrients you need for good health.
A wholegrain lower sugar cereal with semi-skimmed milk and fruit sliced over the top is a tasty and healthier breakfast.
