Do you ever blend up a protein drink for breakfast, or grab a protein bar following an afternoon workout? If so, you are likely among the millions of people in search of more protein-rich diets. Protein-enriched products are found everywhere. But contrary to all the publicity that everyone needs more protein, most Americans get twice as much as they need. Many of us living in the most developed countries are buying into a myth of protein deficiency created by food companies and self-identified health experts. Global retail sales of protein supplement products reached an astonishing US$18.9 billion in 2020. But are we really in need of more protein? Physicians in the U.S. have never actually examined a patient with protein deficiency because simply by eating an adequate number of daily calories we are also most likely getting enough protein. In fact, Americans currently consume almost twice the National Academy of Medicine's recommended daily intake of protein although the most desirable protein intake may vary depending on age and activity level. For example, if you're a dedicated athlete you might need to consume higher quantities of protein. Generally, though, a 140-pound person should not exceed 120 grams of protein per day, particularly because a high protein diet can strain kidney and liver function and increase risks of developing heart disease and cancer. While fats and sugar have taken the beating in turns since over a century ago, protein has managed to remain our red-hot favorite. In the 1970s through the 1990s, protein products remained visible but moved back somewhat with the dietary spotlight firmly fixed on low-calorie, low-fat, sugar-free snack foods and beverages following the publication of studies linking sugar and saturated (饱和的) fat consumption to heart disease. Later research in 2003, however, suggested high-protein diets could aid in weight loss, and protein quickly regained its former nutrient-superstar status. Now most people living in high-income nations are consuming enough protein. When we replace meals with a protein bar or drink, we also risk missing out on the rich sources of antioxidants (抗氧化剂), vitamins and many other benefits of real food.【缺少答案，请补充】

敦煌莫高窟（Mogao Grottoes）数字展示中心于2014年开放启用，是莫高窟保护利用工程的重要组成部分。展示中心采用数字技术和多媒体展示手段，使游客进入洞窟参观之前就能了解莫高窟的历史文化，鉴赏莫高窟的艺术经典。这将减少开放洞窟的数量，缩短游客在洞窟内的逗留时间，减轻参观对莫高窟造成的影响，以使这一世界文化遗产得到妥善保护、长久利用。
