The term grazing is used to describe the eating of small, frequent meals, or mini-meals, throughout the day, typically every three to four hours. Grazing does not mean constantly eating snack foods, but rather is a concept of consuming one's daily food intake, including all necessary nutrients, over five or six (or more) small meals, rather than two or three large ones. Frequent eating can be a great way to maintain one's energy level. This is also a beneficial eating pattern for individuals with gastrointestinal problems such as indigestion and acid reflux. Without a focus on healthy choices, however, grazing can become an easy way to overeat, and could possibly lead to weight gain.
