Ancient Yogurt for Health
Yogurt has been produced for at least 4,000 years. Legend says that an angel taught Abraham how to make yogurt.
Yogurt is a cultured milk product, made by adding certain "good" bacteria to milk, skim milk, and/or cream. It wasn't always easy to come by. Making your own was a lengthy, complicated process.
Today, yogurt is available at stores and supermarkets as well as health food stores all across America.
Following are some tips on reading the labels on yogurt cartons.
- Contains active yogurt cultures means that the bacterial cultures are still present in the yogurt because it has not been heat-treated. Check to see that they are not stabilized with starch or gelatin. U.S. Government regulations require a minimum of two cultures, but some yogurts have as many as five distinct cultures.
- Whole milk yogurt must contain 3.25-percent to 4-percent butterfat, the same as whole milk.
- Low fat yogurt contains the same amount of butterfat as the low fat milks from which they are made. This amount can be between 0.5-percent to 2-percent butterfat.
- Nonfat yogurt or fat-free yogurt must contain less than 0.5-percent butterfat. If the label also says "lite" or "light," it may indicate that the yogurt has been sweetened with aspartame rather than a natural sweetener.
- Made with active cultures means that the yogurt was probably heat-treated, thereby killing the active cultures that produced it.
- "Certified organic" yogurt has been made from milk produced by cows raised under strict organic standards, including an organic diet, no routine treatments with antibiotics or growth hormones, and a healthy growth environment. See: What is Organic?
- Sundae-style yogurt has fruit at the bottom of the container, topped with plain or flavored yogurt.
- Blended yogurt, also called Swiss pudding or custard style yogurt contains pureed fruit or other flavoring ingredients, and a starch or gelatin to give the mixture body.
In the 1970's, few Americans had ever tasted yogurt. Today the average US. consumer eats about five pounds of yogurt per person in a given year. Europeans are eating twice that amount Yogurt is thought to improve our immune system defenses, reducing the risk of colon and breast cancer. There is no doubt that yogurt is a good source of calcium. Plain yogurt has 400mg per-cup more than a cup of skim milk. Yogurt is also rich in protein (8g per cup) and contains as much potassium as a banana, as well as riboflavin (vitamin B2), phosphorus, and magnesium.
Yogurt is crawling with bacteria -- and the more of it you eat, the better. Be sure to buy yogurt with a seal that guarantees it has live, active cultures. These cultures -- especially acidophilus and bifida -- colonize the lower intestines with beneficial bacteria while muscling out disease-causing bacteria. Eating yogurt may help prevent diarrhea in people taking antibiotics. Yogurt is easy to digest, especially for those who are lactose intolerant, and is an excellent source of calcium, protein, riboflavin (a B vitamin), vitamin B-12 (which may be low in vegetarian diets) and vitamin A. To avoid unwanted saturated fat, choose non-fat or low-fat yogurt.
Is Frozen Yogurt Just Yogurt Frozen?
In a word, no. Unlike refrigerated yogurt, which by law must be cultured with specific bacteria, there is no federal standard for frozen yogurt. And while yogurt is one of the ingredients, it's never the only one. Frozen yogurt is usually a mixture of milk (whole, low-fat or skim), sugar, yogurt, flavors or fruit, plus stabilizers and thickeners. Surprisingly, yogurt cultures do survive freezing. They are dormant while frozen, but reactivate once ingested. Pasteurization is more of a problem, as heat kills cultures; to remain active, they must be added after pasteurization. However, the amount of probiotics in a serving of frozen yogurt is much less than what's in a carton of refrigerated yogurt. You can check the label to see if a product contains "active" cultures. But don't count on frozen yogurt as a source of probiotics.
Dairy Dessert to Block Fat?
Finish your lunch or dinner with a container of yogurt, and you may cut the amount of fat your body absorbs from your meal, according to a study recently published in the American Journal of Clinical Nutrition. Danish scientists found that calcium from milk and low-fat yogurt can lower the level of fat in your blood after eating by nearly 20-percent. Researchers believe dairy calcium keeps your body from absorbing fat. A calcium pill with your meal won't have the same effect, however. Study results show supplements don't have the same response in your body. It has to come from dairy foods.
Cooking With Yogurt
When cooking with yogurt, the sweeter flavor of plain low fat yogurt is your best bet because nonfat yogurt has a thin, slightly sour taste. As with other high-protein, high-acid foods, spare the heat. Use low cooking temperatures and short heating periods for best results. Whenever possible, add the yogurt at the end of the cooking period, just in time to let the yogurt mixture come up to serving temperature. If the yogurt is added at the start of the cooking period, you can avoid separation or curdling by stirring a stabilizing mixture of flour or cornstarch blended with a little water into the yogurt.
To keep a thick consistency, it helps to not stir yogurt into other ingredients-instead, fold the yogurt into the mixture. When substituting buttermilk with yogurt, thin the yogurt with a little water or milk to the right consistency. When using yogurt for baking, add 1/2-teaspoon baking soda for each cup of yogurt used.
Use plain low fat yogurt as a substitute for sour cream; you'll save 280 calories per cup. Yogurt can also be used as a partial substitute for mayonnaise (use 50-percent yogurt, 50-percent mayonnaise).
Fat free plain yogurt (1 cup) gives you 49 percent of your daily calcium, 12 percent of magnesium and 18 percent potassium.
Yogurt becomes sharper with age. Stored at a refrigerator temperature of 35 to 45-degrees, yogurt will keep fresh for up to two weeks. The fresher when used, the better the flavor and consistency.
Yogurt loses all its good bacteria when it is heat treated as it is when used in baked goods such as cereal and cereal bars.
Keep live and active culture yogurt stocked in your refrigerator for a low fat or non-fat alternative to mayonnaise and sour cream in sauces, dips and dressings and more. It's so easy to use everyday that you'll discover the possibilities are endless!

- Put it in a box along with a hot water bottle and pack crumpled newspapers loosely around both.
- Turn an electric heating pad to its lowest setting and wrap it around the jar.
- Set the jar in a metal box with a glowing Christmas tree bulb.
- Put it in a gas oven with only the heat from the pilot light.

Light Yogurt. Light yogurt's have fewer calories because they're artifically sweetened. Unfortunately, some brands - like Breyer's Light, Breyers Light YoCrunch, Yoplait Fiber One, Yoplait Light Thick and Creamy, and Dannon Light and Fit 0 percent Plus -- use acesulfame potassium, which hasn't been adequately tested.

Bad: Trader Joe's Greek Style Apricot Mango Yogurt. This one goes overboard with 300 calories, 16 grams of fat, of which 8 grams are saturated, and 23 grams of sugar. Say no to this one.
Good: Dannon Light 'n Fit Greek Vanilla. Plain nonfat yogurt is a nutritional powerhouse. However, if you prefer it with a touch of sweetness, this Dannon choice lives up to its name with only 80 calories, 0 grams of fat and 7 grams of sugar per serving.
Vitamin D. Some yogurts are now fortified. That's a plus if you don't take any extra vitamin D, but the levels - typically 40 IU to 100 IU (10 to 25 percent of the Daily Value) -- don't come close to what most experts recommend (1,000 IU a day).
Greek Style Yogurt. They have more protein and less calcium than ordinary yogurts. Try the fat free versions. FAGE (pronounced FAH-yeh) Total 0 percent, for example, is so rich and creamy that you'll swear it's full fat. Greek yogurt is high in protein, with bloat-busting probiotics. It's ideal for pre-or-post workout snacking.
Nutrition Nibble: Plain low fat yogurts save calories. Add your own fruit and/or sweetener for sweetness.
