Lactose, commonly referred to as milk sugar, is a disaccharide composed of linked glucose and galactose molecules, naturally present in human breast milk, the milk of mammals—including cows—as well as in non-fermented dairy products. The underlying cause of lactose intolerance frequently stems from a congenital deficiency of the enzyme lactase, which is responsible for hydrolyzing lactose into an absorbable form within the digestive tract. Beginning from the second year of life, a gradual decline in the enzyme’s activity is observed, eventually reaching just 5% of its original efficiency. While infants and young children rarely exhibit symptoms of this condition, adolescents and adults may experience its full spectrum of effects, necessitating the complete exclusion from their diet of not only milk itself but also all dairy derivatives to prevent adverse gastrointestinal reactions.
Goat's milk
Goat milk is an easily digestible product as opposed to cow's milk. Both are a good source of calcium, vitamins D, A, and B. Goatmilk contains a lot of volatile fatty acids, mainly capron, caprine, and caprylic, which are produced by lipoprotein lipase. Compared with cow milk and goat milk, they are very similar. However, it also contains many exogenous amino acids that are well absorbed by the human body. Additionally, whether the fat in cow milk is dihydroxy (dihydrocarboxylic acid) can cause significantly less allergic reactions in the milk.
Goat's milk and lactose
Lactose is a very important sugar that supports the absorption of calcium, phosphorus, magnesium and other elements, and is also a source of galactose that affects the proper structure of the nervous system. Cow's milk and females are rich in large amounts of this sugar. Goat's Milk contains a much smaller amount of it. It is only about 10% of its composition. However, even small amounts can cause side effects and lead to irritation of the baby's intestines, which can result in diarrhea, stomach pain and bloating.
Goat's milk is for babies
Despite the many positive components that contribute to infant growth, malnutrition and lower lactose content, goat's milk is not recommended for children under the age of one year. A much higher mineral content can significantly strain the child's kidneys, and folic acid deficiency can lead to nervous system problems. Lactose intolerance, especially in young children, is a serious problem because milk is the primary food in the first few months of life of the child. Even the smallest amounts of sugar can cause intolerances and food insecurity on the part of the diet.
