Tomato Consumption and Health: Emerging Benefits

摘要

Tomatoes and tomato products are one of the most familiar vegetables in the American diet. Quantitatively, they are the most consumed nonstarchy vegetable and are the most significant source of dietary lycopene; a powerful antioxidant that has greater bioavailability after cooking and processing (eg, canning). A large body of research supports an inverse relationship between consuming tomatoes and tomato products and risk of certain cancers, while emerging research is exploring the protective relationship between tomato intake and a host of conditions, including cardiovascular disease, osteoporosis, ultraviolet light-induced skin damage, and cognitive dysfunction. Initial studies of tomato consumption and disease risk reduction focused on lycopene and antioxidant activity. More recent hypotheses recognize the advantages of the whole tomato; and hence, research on the role of tomato products in health and disease risk reduction extends beyond antioxidant function to include other protective mechanisms such as antithrombotic and anti-inflammatory functions. Increasing daily vegetable intake in the American diet offers the potential to yield significant health benefits. In addition to the specific benefits of tomato consumption, encouraging greater tomato and tomato product consumption may help increase overall vegetable intake because of their wide availability, well-established acceptability, cost-effectiveness, and convenience of multiple forms. Leveraging emerging science about tomatoes and tomato products may be one simple and effective strategy to help individuals increase vegetable intake, leading to improved overall eating patterns, and ultimately, better health.
