Eating a healthy, balanced diet is an important part of maintaining good health, and can help you feel your best.
This means eating a wide variety of foods in the right proportions, and consuming the right amount of food and drink to achieve and maintain a healthy body weight.
To find out if you're a healthy weight for your height, work out your body mass index (BMI).
You can easily check your BMI by using our BMI calculator. A BMI between 18.5 and 24.9 is considered healthy.
The BMI calculator can also be used to check if your child is a healthy weight.

Many people with sexually transmitted infections (STIs) do not get symptoms, so it's worth getting tested even if you feel fine. If you think you have an STI, the earlier you're tested, the sooner treatment can be given if it's needed.
An STI can be passed from one person to another through sexual contact, including vaginal, anal and oral sex.
STIs can pass between men and women, and from women to women and men to men.
Many STIs can be cured with antibiotics. Some, such as HIV, have no cure, but can be treated to prevent them getting worse.
You cannot tell by looking at someone (including yourself) whether they have an infection, so it's important to get a check-up if you have had unprotected sex or think you might be at risk.
