Health food is food considered beneficial to health in ways that go beyond a normal healthy diet required for human nutrition. Because there is no precise, authoritative definition from regulatory agencies such as the U.S. Food and Drug Administration, different dietary practices can be considered healthy depending on context.
Foods considered "healthy" may be natural foods, organic foods, whole foods, and sometimes vegetarian or dietary supplements. Such products are sold in health food stores or in the health/organic sections of supermarkets.

Lemons
Just one lemon has more than 100 percent of your daily intake of vitamin C, which may help increase "good" HDL cholesterol levels and strengthen bones.
