Dietary standards are guidelines that help individuals understand the types and amounts of food they should consume for optimal health. These standards are often based on scientific research and aim to prevent nutritional deficiencies and chronic diseases. They consider factors such as age, sex, and activity level to provide tailored recommendations. Organizations like the World Health Organization (WHO) and the Food and Agriculture Organization (FAO) develop these standards to promote healthy eating habits. They often include recommendations for daily servings of fruits, vegetables, grains, and proteins, as well as limits on sugar, salt, and unhealthy fats.
