Yogurt Consumption as a Signature of a Healthy Diet and Lifestyle.

Yogurt is considered to be a nutrient-dense food that significantly contributes to the intake of several nutrients, including calcium and protein. As described in this paper, yogurt consumers have a higher nutrient intake than do nonconsumers. Yogurt consumers are also characterized by healthier dietary habits than nonconsumers, which partly explains their reduced incidence of overweight and obesity. Recent studies also suggest that yogurt consumers exhibit healthier nonnutritional behaviors, such as reduced smoking and greater participation in physical activity, than do nonconsumers. Furthermore, when greenhouse gas emissions are used as an additional criterion to categorize foods, yogurt appears to be an eco-friendly food. Compared with that of other foods, the carbon footprint of yogurt production is low to moderate and may be included as part of a healthy and sustainable diet. Based on these factors, yogurt consumption may be the signature of a healthy diet and lifestyle.
