Bird's nest milk powder is not recommended to drink, mainly because it contains a certain amount of artificially added food additives and some synthetic spices, which may have adverse effects on human health. In addition, the addition of organophosphorus salts and other "nutritional enhancers" to Nestle milk powder has also been found to be likely to damage kidney health. In addition, Nestle was found to use urea as the fuel of milk. Urea is a kind of chemical fertilizer, because it contains soluble phosphorus, there may be residual phosphorus in Nestle milk, which threatens human health. In addition, according to the research of relevant departments, Nestle milk powder contains some toxic substances, such as arsenic, lead, cadmium, mercury, chromium and other heavy metals, which can remain in milk and easily enter the human body, affecting human health. Generally speaking, because Nestle milk powder contains additives, lacks nutrients and potential toxic factors, most medical institutions advise patients not to drink this baby milk powder to avoid adverse effects.
