Core Viewpoint - The event "518 National Nutrition Festival" focuses on the importance of high-quality protein intake to address current nutritional challenges faced by the public [1] Group 1: Nutritional Challenges - 45% of adult residents in China are at risk of insufficient protein intake [1] - 55.71% of children have a single source of protein, while 89.55% of elderly individuals face intake shortages due to declining digestive absorption [1] - Nearly 60% of individuals on weight loss programs experience a sharp decline in protein intake, and over 70% of respondents are unaware of how to scientifically supplement protein [1] Group 2: Expert Insights - The president of the Chinese Nutrition Society emphasizes the need for engaging and practical public education to enhance understanding of the role of high-quality protein in health, particularly in boosting immunity and maintaining muscle mass [1] - Recommendations suggest that adults should consume 1 gram of protein per kilogram of body weight daily, with an increase to 1.2 grams for individuals aged 65 and above, and that high-quality protein should constitute over half of total protein intake [1] - The scientific combination of animal and plant proteins is highlighted for its higher nutritional value and better digestibility, which can benefit specific populations such as the elderly and athletes [1]

Core Viewpoint - The article emphasizes that soy products, when consumed correctly, can be beneficial for health, particularly for patients with kidney disease, who can select appropriate types of soybeans and soy products [1]. Group 1: Nutritional Benefits of Soy - Soybeans provide high-quality protein, which is easily digestible and has a similar amino acid profile to animal proteins, making it a complete protein source [2]. - Soy protein contains 18 types of amino acids and is rich in lysine, complementing the deficiencies found in cereal proteins [2]. - Special components in soy, such as isoflavones and saponins, contribute to various health benefits, including cholesterol reduction and antioxidant properties [2]. Group 2: Recommendations for Kidney Patients - Kidney patients should adopt a "high-quality low-protein" dietary strategy, allowing for the scientific consumption of soy and soy products to meet protein needs while reducing metabolic burden [3]. - It is crucial to distinguish between soybeans (yellow, black, and green beans) and other legumes, as only the former contain high-quality protein, while others like red beans and mung beans are considered inferior and should be limited [4]. Group 3: Suitable Soy Products - Among the various soy products, tofu and soy milk are recommended for kidney patients, while processed products high in salt and oil, such as fried tofu skin, should be avoided [5]. - Patients should ensure that the soy products they purchase are made from soybeans, particularly yellow soybeans, to maximize health benefits [5].
