The media has been reporting that eating pineapples can prevent SARS, so the price of pineapples has immediately skyrocketed, and everyone is rushing to buy them. In fact, because my family runs a fruit shop, I've known for a long time that pineapples can boost immunity. In the past, whenever I had a cold, fever, or felt a bit unwell, I would eat some pineapple or drink a glass of pineapple juice, and it would alleviate the symptoms quite a bit. Because I've always had the habit of eating pineapples, I rarely catch a cold. Pineapples have always been my favorite.
