1. Grain-fed beef
It just so happens that the digestive systems of cows are designed to process grass, not grains. So why are farmers shoving their cattle into sheds and force-feeding them things like soybeans, corn or rapeseed? The answer lies in productivity — cows that are fed grains fatten up faster, meaning they’re ready for the slaughter quicker than grass-fed cows. This means greater productivity for the farmer, but it means the cows are far less healthy.
The result is beef which is pro-inflammatory, high in omega-6 fatty acids and low in heart-healthy omega-3s, and which often has residual antibiotics and pesticides from the feed they’re given. Nasty!
