So fun fact. I bought this organic whole pineapple at Whole Foods in Beacon Hill for $2.50. It yielded about 3-4 c (since I ate some in the process and can’t get an accurate reading). If you buy pre-cut pineapple pieces, it’s $4-7 depending on how many cups you bought. To save some many and reap all of the benefits, here’s How to Cut a Pineapple. Pineapples are high in vitamin C, fiber and other vitamins and minerals. Grill it, freeze it, keep it raw, transform it into a salsa. They’re also high in natural sugar and a great sweetener for smoothies, muffins, bowls, oats — anything.
