Skimmed milk powder fortified with vitamin D is recommended for ages 50 to 60. You can also choose other products according to your situation. Men between the ages of 50 and 60 are gradually entering old age and the risk of osteoporosis is intensifying. Women are very susceptible to osteoporosis and other problems as their body’s absorption of calcium drops considerably after they enter menopause due to estrogen levels. Evidence shows that five years after menopause, half of women are at risk of osteoporosis. So this is the time to choose a milk powder fortified with vitamin D to boost the absorption of calcium in the gut to counter the threat of osteoporosis. Next, use skim milk powder. The vast majority of the problems of modern people are over-nutrition and high-fat and high-cholesterol problems. Whole milk powder is actually not low in fat. Generally speaking, there are about 5 grams of fat per 100 milliliters of milk powder in a well-brewed milk powder, which means there is a 5% fat rate. Cows are ruminants, and ruminant fat contains trans fatty acids, which increase the risk of cardiovascular disease in humans. Skimmed milk powder can solve these two problems. So for all these reasons, skim milk powder fortified with vitamin D is recommended for people aged 50 to 60. You can also choose other products according to your special situation, such as lactose intolerant people choose lactose-free milk powder and so on.
