不少人有这样的疑问：想要减肥，运动后如何进食？目标增肌，练完不吃是否影响增肌效果？ 这是因为，运动后的30分钟内，肠胃血流较少，消化吸收能力较弱。运动后的30分钟到1小时，体内的 骨骼肌细胞会为碳水化合物、氨基酸等营养素"打开通道"。这时，如果营养补充及时、恰当，肌肉修复 及增长速度较为理想。如果在晚上运动，建议算好睡眠时间，避免在睡前4小时内过量进食，既影响睡 眠质量，也影响运动效果。 吃什么？选对营养是关键。 糖原、脂肪、蛋白质，这些营养物质都可以提供能量，但消耗的比例会因运动类型的不同而有所区别。 在短距离赛跑、举重等高强度、短时间运动中，糖原是主要的能量来源。在慢跑、游泳、爬山等中低强 度、长时间运动中，脂肪的供能比例会更高。蛋白质则会在糖原不足和长时间运动的情况下，少量参与 供能。因此，运动后的饮食也应有所侧重。 《国际运动营养学会杂志》介绍，每1公斤体重摄入0.8克至1.2克碳水化合物与0.2克至0.4克蛋白质较为 合适。由于大部分碳水化合物是合成糖原的"原料"，针对运动中糖原的消耗，应该摄入富含碳水化合物 的食物，如荞麦面包、香蕉、燕麦等，能快速补充能量。对于运动中脂肪的消耗，虽然不少人努力运动 ...

不少人有这样的疑问：想要减肥，运动后如何进食？目标增肌，练完不吃是否影响增肌效果？ 运动固然能促进新陈代谢、燃烧热量，但同时也消耗了大量营养。若运动后饮食不当，也可能导致运动 效果大打折扣。 糖原、脂肪、蛋白质，这些营养物质都可以提供能量，但消耗的比例会因运动类型的不同而有所区别。 在短距离赛跑、举重等高强度、短时间运动中，糖原是主要的能量来源。在慢跑、游泳、爬山等中低强 度、长时间运动中，脂肪的供能比例会更高。蛋白质则会在糖原不足和长时间运动的情况下，少量参与 供能。因此，运动后的饮食也应有所侧重。 《国际运动营养学会杂志》介绍，每1公斤体重摄入0.8克至1.2克碳水化合物与0.2克至0.4克蛋白质较为 合适。由于大部分碳水化合物是合成糖原的"原料"，针对运动中糖原的消耗，应该摄入富含碳水化合物 的食物，如荞麦面包、香蕉、燕麦等，能快速补充能量。对于运动中脂肪的消耗，虽然不少人努力运动 是为了减脂，但出于维护机体免疫系统的考虑，最好不要完全避开脂肪的摄入，在运动后可适当吃一点 坚果、牛油果等。在运动后适量补充鸡蛋蛋白、精瘦肉等富含优质蛋白的食物，能促进肌肉恢复，提升 身体机能。对于有科学减重需求的人群和希望 ...

Group 1 - The article emphasizes that many popular health practices may not be beneficial and could even be harmful to health [1] - Drinking honey water in the morning can raise blood sugar levels, which is detrimental for diabetics, and may not effectively prevent constipation for most people [2] - Consuming salt water in the morning is unnecessary for detoxification and can lead to excessive salt intake, increasing the risk of osteoporosis and hypertension [3] Group 2 - Drinking plain water at a temperature between 20°C and 40°C is recommended as the best choice for the first drink in the morning, as excessively hot water can increase the risk of esophageal cancer [4] - White rice porridge is nutritionally poor and may exacerbate malnutrition if consumed exclusively, while incorporating whole grains can improve nutritional intake and stabilize blood sugar levels [6] - Bone broth is often believed to be a good source of calcium, but its actual calcium content is minimal, making it ineffective for calcium supplementation [7] Group 3 - While pig's trotters are rich in collagen, they do not effectively contribute to collagen synthesis in the body compared to other protein sources [8] - The high saturated fat content in pig's trotters can be detrimental to cardiovascular health, suggesting limited consumption [9] - Drinking red sugar water for menstrual pain relief is based on psychological effects rather than any specific nutritional benefit, and it is ineffective for pain caused by underlying medical conditions [10] Group 4 - Juicing fruits leads to a loss of nutrients, particularly vitamin C, and can significantly increase blood sugar levels due to the release of free sugars [12][14] - Cooking oil that smokes can produce harmful trans fats and carcinogens, and it is advised to use a method that prevents this [15] - Consuming food while it is still hot can pose risks, as temperatures above 65°C are classified as carcinogenic, and can also affect the glycemic index of starchy foods [16] Group 5 - Allowing food to cool at room temperature before refrigerating can promote bacterial growth, increasing the risk of foodborne illness; it is safer to store hot food directly in sanitized containers [18]

Hydration - It is essential to drink water regularly and consume water-rich foods to maintain hydration during high temperatures. The amount of water intake should be based on sweat loss, temperature, and activity level [1] - Sweet beverages do not provide necessary electrolytes like sodium and potassium, making options like fruits, vegetables, nutritious porridge, soup, and lightly salted water better choices for hydration [1] Salt Supplementation - Sodium and potassium are lost through sweat, so it is important not to overly restrict salt intake in hot conditions. Light saltwater is recommended for replenishment [2] - Dietary sources should be prioritized for salt intake, with a variety of soups suggested to enhance daily salt consumption. In cases of high sweat loss, electrolyte-rich beverages may be necessary [2] Increased Vegetable and Fruit Intake - The need for vitamins B1, B2, C, and β-carotene increases in high temperatures, making it important to consume more fruits and vegetables to replenish lost nutrients [3] - Daily recommendations include at least 500g of vegetables and 400g of fruits, focusing on potassium and vitamin-rich options [3] Quality Protein Intake - Protein requirements slightly increase in hot weather, with a recommended energy contribution of 12%-15% from protein, half of which should be high-quality sources [4] - Foods rich in quality protein such as fish, shrimp, eggs, dairy, and lean meats should be included, with specific daily intake recommendations for dairy and soy products [4] Carbohydrate Consumption - Carbohydrates are a vital energy source, and it is advisable to choose complex carbohydrates like whole grain bread and brown rice to provide sustained energy without causing blood sugar spikes [5] Appetite Stimulation - Due to reduced digestive secretions in high temperatures, meals should be visually appealing and varied to stimulate appetite. Light soups before meals can help enhance digestion and appetite [6][7] - Cold dishes and small amounts of cold drinks can also aid in appetite stimulation, but should be consumed in moderation to avoid gastrointestinal discomfort [7] Food Safety - High temperatures accelerate food spoilage and bacterial growth, necessitating strict food hygiene practices. Freshly prepared foods should be prioritized, and stored foods must be checked for quality before consumption [8]
