A healthy diet is one that helps maintain or improve general health. It is thought to be important for lowering health risks, such as obesity, heart disease, diabetes, hypertension and cancer. A healthy diet involves consuming primarily fruits, vegetables, and whole grains to satisfy caloric requirements, provide the body with essential nutrients, phytochemicals, and fibre, and provide adequate water intake. A healthy diet supports energy needs and provides for human nutrition without exposure to toxicity or excessive weight gain from consuming excessive amounts.
