The Benefits of Yogurt ------------------------------------------------------------------------------ QUESTION: My boyfriend is on a new health kick, and this time it is yogurt. Every conversation seems to turn to the marvels of this food (boring!). Can you please discuss this in your column so that I can set him straight, and put a stop to these endless lectures on "long life through yogurt"? I would be very, very grateful. ------------------------------------------------------------------------------ ANSWER: Ever since a bacteriologist, Elie Metchnikoff, credited yogurt for the long lives of yogurt eating Russians who live in the Cactuses region, the legend has grown, supported by innumerable articles in health magazines and journals. From a strictly scientific point of view, there are some interesting nutritional points that can be offered. Yogurt is made from milk, and contains many of the nutritional benefits of this liquid food. It is converted into yogurt by the action of two bacteria, Lactobacillus bulgaricus and Streptococcus thermophilus through a process known as "lactic acid fermentation". Depending upon the production techniques used in bringing the final product to the market, the bacteria may still be found alive and active in the yogurt, or are no longer present, destroyed by a heat treatment after culturing. While different yogurt may contain different amounts of nutrients, all contain substantial amounts of protein, calcium, and lactose. Different categories of yogurt, whole milk, low fat, and non-fat yogurts contain varying amounts of fat from a high of 7 grams per serving to the non-fat low of 1 gram or less per serving. Caloric values of servings also vary depending upon the amount of added sugar contained in many of the fruit flavored varieties. Current research is looking at the possible role of the live bacteria variety and the lactic acid they produce. It seems that these bacteria do survive the digestion process and may have a role in reducing blood cholesterol levels and the incidence of intestinal tumors. It may not be the road to long life, but the nutritional value of yogurt in a balanced diet can not be disputed. This may not turn off your boyfriend, but at least now you have a bit more knowledge about the subject. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
