Through every phase of your life, your body needs different good groups to survive and stay healthy.
When you're in your prime, "energy is everything", says OK! magazine.
In her new book, serialised in OK! magazine, Jane Clarke explains: "On average three meals a day with a couple of nutritious snacks in between is a good pattern to work to."
Hydration is key and it is vital to keep energy levels constant, the nutrition expert said.
When it comes to the stage at which you might want to get pregnant, Jane advises eating a good balance and "spectrum" of different foods, reports OK! magazine.
"However, if all you can stomach at the beginning is white toast, don't panic," she said. "The amazing thing about pregnancy is that your baby will take only what it needs from your stores."
Recently, HEART UK - The Cholesterol Charity, said people could find eating dark chocolate beneficial as long as they eat it as part of a balanced diet.
