We all know that it's important to eat healthy food. But what does that mean? Many people think that 'healthy' means 'not very tasty', but this is not true. Healthy food can be delicious, too! Here are some tips for a healthy diet. 1 Eat lots of fruit and vegetables. They're full of vitamins, minerals and fibre. Try to eat five portions every day. A portion is about the size of your hand. You can eat fresh fruit or vegetables, or you can cook them. 2 Eat less salt. Too much salt is bad for you because it can make your blood pressure high. Don't add salt to your food when you cook. And don't put salt on your food at the table, either. If you do this, you'll get used to the taste of the food. And if you want to enjoy the taste of your food more, try adding herbs or spices to it instead of salt. 3 Eat less sugar. Sugar is bad for your teeth, and it can also make you fat. Try not to eat too many sweets or chocolates. And be careful with drinks like cola and lemonade - they have a lot of sugar in them, too. It's better to drink water or fruit juice. 4 Eat less fat. Fat is very high in calories, so eating too much of it can make you fat. But you need some fat in your diet, so don't stop eating it completely. Just choose healthier fats, like olive oil and sunflower oil, and eat less of the unhealthy ones, like butter and cream. 5 Don't skip breakfast! Breakfast is the most important meal of the day. It gives you energy for the whole morning. So don't go to school without eating anything. Try to eat a healthy breakfast every day. For example, you could have some cereal with milk and a piece of fruit. I. Write down true or false: 1. Healthy food is not tasty. 2. Eating lots of fruit and vegetables is good for your health. 3. A portion of fruit or vegetables is about the size of your hand. 4. Adding salt to your food makes it taste better. 5. Sugar is good for your teeth. 6. Cola and lemonade have a lot of sugar in them. 7. It's better to drink water or fruit juice instead of sugary drinks. 8. Eating fat can make you gain weight. 9. You should completely stop eating fat. 10. Breakfast is the least important meal of the day.
