Dairy
Lots of people assume that if they love it, it should be off-limitsâwhich is why dairy items like cheese and milk donât usually make the cut in many âhealthyâ diets. However, they can be a great source of calcium and potassium. Youâre only going to get that eight grammes of protein from animal milk, so youâre losing that if you switch to soy, almond, or coconut, London says. Dairy is a good source of calcium, so, donât ditch it for the wrong reasons.
