Science Has Spoken Grass-fed Butter Eaters Have Fewer Heart Attacks

March 19, 2016

Butter has a bad reputation associated with healthy diet and the risk of heart disease. Butter is composed of fat only, and some people tend to avoid the butter in their daily diet. However, butter contributes to human health, especially those made of milk from grass-fed cows.

Science Has Spoken Grass-fed Butter Eaters Have Fewer Heart Attacks

It turns that cow’s diet has an influence on butter made of cow milk, thus affecting the cardiovascular condition of the consumer. Basically, healthy butter contains two substances; CLA (conjugated linoleic acid) and omega-3 fatty acids. When cows are given grass instead of grain and other substances, their milk contains CLA and omega-3 in greater numbers.

Based on some well-known studies, omega-3 fatty acids are cardio protective, maintaining hearth health and reducing the risk of hyperlipidemia (high cholesterol level). The milk from grass-fed cows produces CLA up to 5 times more.

Saturated Fat Myth

Commonly believed myth is that saturated fats have a bad effect on your health. 32 studies in 2014 found that there is no link between polyunsaturated fats with heart health. The 32 studies have relevance to a study in 2010 stated that there is no correlation between high diet in saturated fats with heart attack risk. From these studies we can conclude that the myth of saturated fat doesn’t have any supporter.

Location

Two studies were conducted in 2009 and 2010 found one other factor associated with the benefits of dairy products from grass-fed cows. There are two studies on the effect of livestock location in Australia and Sweden. Two of these studies found that milk intake is inversely related to the risk of heart disease and milk intake is not directly related to the death. One interesting thing is that Australia and Sweden are two countries where grass is always given as a staple food for cows. You can view information about the cows (cow’s diet) on the label of most dairy products.
