Your food therefore needs to provide all the energy, essential fatty acids, amino acids, vitamins and minerals you need for optimum health. Fruit, vegetables, nuts and seeds also provide substances that contribute to colour and flavour as well as protecting plants against sun, viruses, bacteria and other predators.

Known as phytochemicals, these have beneficial effects on human health, too, providing some protection against high blood pressure, raised cholesterol, diabetes, obesity, heart disease, stroke, visual loss and even cancer. The average diet is believed to supply more than 1 gram of phytochemicals per day.

Aim for colour on your plate for a good mix of phytochemicals – mix dark green, orange, yellow, red and purple fruit and vegetables as much as possible.
