It is recommended that 80-90 year olds drink high-calcium, low-fat milk powder to replenish the organism with the required nutrients. 1. High calcium: for the elderly, due to the decline of physiological functions, there is a general lack of calcium intake. The daily calcium intake of the elderly needs to be about 1000mg, so high-calcium milk powder is beneficial to meet the needs of the elderly for calcium. 2. Low-fat: The digestive function of the elderly is weak, the absorption of fat decreases, and obesity or hyperlipidemia is easy to occur at the same time. Therefore, the consumption of low-fat milk powder will not bring too much physical burden to the elderly, but also can avoid the rise of blood fat and cholesterol. There are a variety of formulas of high-calcium low-fat milk powder on the market, so you can choose according to your own situation. It should be noted that milk powder is beneficial to the body, but it should be consumed in moderation, and those who are allergic to milk powder should also avoid consuming it.
