1Do you ever blend up a protein drink for breakfast, or grab a protein bar following an afternoon workout? If so, you are
2likely among the millions of people in search of more protein-rich diets. Protein-enriched products are found
3everywhere. But contrary to all the publicity that everyone needs more protein, most Americans get twice as much as they
4need. Many of us living in the most developed countries are buying into a myth of protein deficiency created by food
5companies and selMdentified health experts. Global retail sales of protein supplement products reached an astonishing
6US$18,9 billion in 2020. But are we really in need of more protein? Physicians in the U.S. have never actually examined
7a patient with protein deficiency because simply by eating an adequate number of daily calories we are also most likely
8getting enough protein. In fact, Americans currently consume almost twice the National Academy of Medicine's recommended
9daily intake of protein although the most desirable protein intake may vary depending on age and activity level. For
10example, if you're a dedicated athlete you might need to consume higher quantities of protein. Generally, though, a
11140-pound person should not exceed 120 grams of protein per day, particularly because a high protein diet can strain
12kidney and liver function and increase risks of developing heart disease and cancer. While fats and sugar have taken the
13beating in turns since over a century ago, protein has managed to remain our red-hot favorite. In the 1970s through the
141990s, protein products remained visible but moved back somewhat with the dietary spotlight firmly fixed on low-calorie,
15low-fat, sugar-free snack foods and beverages following the publication of studies linking sugar and saturated ( 饱和的)
16fat consumption to heart disease. Later research in 2003, however, suggested high-protein diets could aid in weight
17loss, and protein quickly regained its former nutrient-superstar status. Now most people living in high-income nations
18are consuming enough protein. When we replace meals with a protein bar or drink, we also risk missing out on the rich
19sources of antioxidants (抗氧化剂),vitamins and many other benefits of real food.
