From chocolate shakes for children to a cup of tea for elders, milk has been an essential ingredient of our daily routine. Many referred to it as a “wholesome ingredient” due to its nutritional profile and various health benefits, 

But the question is, have you ever thought that a cow breed can highly impact on your health? Absolutely not, or maybe. It’s a fact that cow breeds can affect your health, either making it better or else worsening it. However, the question might be crossing your mind: how can a simple white liquid cause such fluctuations in health?
