Improving the levels of essential nutrients in the Asia-Pacific region can help improve health, especially for older adults. Factors like age, diseases, and medications can affect how well people get these nutrients. Interventions like changing diets, adding nutrients to food, or taking supplements can help. However, there is not enough data on what people are eating in these countries. Many countries in the region have low levels of vitamins A, D, E, C, B-6, B-12, folate, and zinc. Using average and standard deviation data can help estimate how many people are lacking these important nutrients.
