Until now, it is still a constant topic on how much milk should we really drink as different studies show varying results. One of the most common debate is that why do we need to drink cow's milk when it's actually meant for calves.
Although a lot of experts argued that we do not need to drink milk, others still suggest that our genes have evolved enough to handle cow's milk.
Milk contains a variety of vitamins and minerals. It is also considered the primary source of calcium in the American diet, wherein it packs with vitamin D, magnesium, potassium, protein, etc.
However, milk does have its downsides. The majority of the world's population some degree of intolerance toward consuming milk, as well as other dairy products. Some people can experience diarrhea, bloating, nausea, and other related symptoms depending on the severity.
A research also suggested that dairy consumption is linked to acne. Milk likely contains certain hormones that could increase the oil production in skin. This could trigger breakouts in susceptible individuals.
Still, the impact of milk in our body is still unclear due to inconsistent findings. It may have to do with different factors like the amount of fat, the health of the cow, and the role of other dairy products in the diet.
This has been reflected in the recent meta-analysis led by Maciej Banach, a professor at the Medical University of Lodz in Poland. His research team found a link between higher milk consumption and a higher risk of coronary heart disease, and also found a lower risk of cerebrovascular mortality.
At the moment, federal guidelines advise to only consume 3 cups of foods from the dairy group every day.
"In light of the protective effects of dairy products, public health officials should revise the guidelines on dairy consumption," Banach said.
Still, emerging evidence states the opposite. The best way to get around this is to make sure your overall diet is balanced.
