Milk
Placed in the same category as eggs, milk is another kitchen staple you should avoid when on sale. In general, milk is an excellent source of good quality protein and vitamins like vitamin D, vitamin B12, and riboflavin. In fact, milk is also a pretty good source of thiamine, vitamin A, magnesium, and zinc.
Sadly, all those health benefits you get from milk’s nutrients and vitamins can go to waste if you’re not buying a good product. Before buying a discounted carton of milk, make sure to check its expiration date. You could buy a carton of milk that’s actually spoiled.
