As controversial as it sounds, health organizations recommend the intake of dairy to us and push the idea that dairy products are essential to bone health and development. Although some dairy products are more beneficial than others, it is important to understand which sources of dairy products are more essential and which ones are not. This way we could gear towards making substitutions here and there for better nutrient and vitamin quality.
Lactose is the main carbohydrate in dairy. Lactose is made up of two simple sugars, glucose and galactose. Glucose is a simple sugar that circulates the blood of animals/humans as blood sugar. Galactose is a nonessential nutrient which has an affect on the aging process.
Lactase is a digestive enzyme that is released during breastfeeding for infants to breakdown lactose. This ability is lost during adulthood which is called lactose intolerant. About 3/4 of the worlds population is lactose intolerant. Calcium is the main mineral in bones. While many dairy products contain great sources of calcium, full fat dairy or grass fed cows are the best dairy sources. Grass fed cows have a greater nutrient benefit including more fatty acids and more fat soluble vitamins. Cows milk is fed to growing calves for the purpose of developing them rapidly from a calf to a cow. Humans at adulthood do not need to grow any longer, from a biological aspect, so humans should not drink cows milk.
I refrained from consuming dairy about five years ago. Dairy for me added more mucus than my body should actually produce which was detrimental to my asthma as well as overall health. Doctors told me to switch my milk back when I was a toddler from whole milk to 2%. Throughout high school I then started to realize how my body began to change and became more intolerant to lactose. I made a switch to more lactose free products and added more calcium to my diet such as green vegetables, almonds, and figs just to name some examples. Consider making small changes to rid your diet of dairy products. It will not happen in a day nor one month but patience, gaining knowledge, and having an understanding of yourself it could be done!
