assalamualaikum and hi guys. I just found a short message about healthy lifestyle, excerpted from an article. Before this, i often heard about 'phytochemicals' but i can't see what its function really is. I hope I can get more info after this.

A good diet is important for good health. A healthy and varied diet can help to maintain a healthy body weight, enhance general wellbeing and reduce the risk of a number of diseases including heart disease, stroke, cancer, diabetes and osteoporosis

Phytochemicals, also known as bioactive substances, are compounds commonly found in plant foods that are not considered to be nutrients but may have beneficial effects on health, helping to protect against a number of diseases such as heart disease and cancer.

What about supplements?
For most healthy people, a varied and balanced diet will provide all the vitamins and minerals the body needs. There are certain times in our lives when we may benefit from taking supplements but remember supplements cannot replace a healthy diet. If you think that your diet is not meeting your nutrient requirements, a multivitamin and mineral supplement may be of benefit. Avoid supplements with high doses of single vitamins or minerals as these may well be unnecessary and should not be taken without seeking medical advice.
