In another hadith, the Prophet (salAllahu 'alayhi wa sallam) said, "Raise cows, because their milk is a cure (from disease) and their butter is a medication. Their meat, however, is (a cause of) illness"

I came across these ahadith a few days back and I decided to do some research to see whether what the Prophet Muhammad (PBUH) told us so long ago, has been 'scientifically proven' by the medical professionals.

I'd like to point out that the hadith doesn't necessarily say that red meat is haraam but instead reminds us to be cautious of our consumption of this type of meat. We all know the health benefits of red meat, especially now since it's been stressed on so much but what we tend to overlook is - moderation!
Excessive consumption of red meat can result in clogged arteries, boost blood pressure, and allow cancer cells to sneak past the bodies own self defense mechanism. Diets high in red meat are known to shorten life span & lead to diabetes, Alzheimer's disease, ulcers, pneumonia, influenza, liver disease, tuberculosis, chronic obstructive pulmonary disease and more.
Look after yourselves, follow a nutritious diet and a healthy lifestyle and make the most of what you've been blessed with. Good health is a blessing from Allah, don't take it for granted.
