47. Margarine, an artificial lubricant
Margarine has come under heavy fire of late, and with good reason. It looks like butter, in some cases even tastes like butter, but it is nothing like butter. Margarine is an artificial lubricant with artery-clogging saturated fats and loads of processed oils. It is no friend to your cholesterol. Many margarine brands use propylene glycol, which is an artificial compound.
This compound has been found to increase bad cholesterol, and it is also associated with weight gain. Those morning pancakes with syrup and margarine can be no more, lest you increase your chances of a heart attack or start growing sideways. It might cost a bit more, but you could substitute the margarine with butter or heavy oils like coconut or extra virgin olive. Unlike margarine, these fats and oils are good for your health.
