摘要：This paper reviews the available literatures and research findings on the effect of caffeine on health and nutrition. Caffeine is a mild stimulant found in many of our favorite beverages and some of our foods, such as coffees, teas, colas, and even chocolate. Caffeine can negatively affect our health if it is not consumed in moderation. Caffeine can cause nutrient depletion of important nutrients, like vitamin B6, and interfere with nutrient absorption of essential minerals, including calcium, iron, magnesium and B vitamins. Studies have found caffeine consumption is associated with reduced risk of developing type 2 diabetes, although the mechanisms are unclear. However, sensitive sub-populations, including pregnant women, children and older individuals, and those with a history of heart disease, may experience effects at lower levels of caffeine and should limit their consumption to three cups of coffee per day, or no more than 300 mg/ day, to avoid adverse effects. Thus, the purpose of this paper is to review the effect of caffeine on health and nutrition.
