Diseases Related to Drinking Cow’s Milk

· August 16, 2015

Cow’s milk and its derivatives are currently one of the most consumed foods in the world; all the properties, delicious flavor, and content of vitamins and minerals that cow’s milk provides your body with have been valued for centuries, especially calcium. However, recent studies have questioned the supposed benefits of cow’s milk a lot, because in contrast to what was thought, excessive consumption of cow’s milk may worsen your health and cause different diseases.

Why Is Cow’s Milk Bad for Your Health?

Many people ask why is cow’s milk bad for your health if we have consumed it for centuries? To answer this, we have to go back in time a little bit, to the sixties more or less, when they started to artificially modify the natural growth of cows. Studies show that around the 1800’s, cows started to produce around 9 liters of milk a day. Nowadays, they have applied new techniques of artificial animal growth — for example, the use of antibiotics, genetic selection, change in diet, and  use of growth hormones — that have made cows able to produce up to 24 liters of milk a day. It is amazing to see how cows went from producing 2 liters of milk to 24 or even more a day.

Although the artificial growth techniques have given a lot of economic benefits to dairy and meat industries, the truth is that this change from what’s natural has consequences that are affecting consumers because the milk is affected by how the animal is raised, antibiotics, hormones, diet, etc. As a consequence, it can cause different health issues over the years.

Studies on the impact of cow’s milk on health have been done over many years and coincide as to how this product can affect people’s health. Recently, a study from Harvard University recognized what happened from cow’s milk and stated that there is a relationship between excessive consumption of this product and the development of different diseases.
