Yogurt tolerated better than milk by lactose intolerant individuals
(17-March-2005) Researchers now say people with lactose intolerance--in other words, those who are allergic to milk products--can usually tolerate yogurt. It’s just one more reason to reach for a yogurt after your workout. Dieticians note that yogurt is low in fat but high in calcium. Yogurt also contains plenty of vitamins and minerals, including B-12, riboflavin, potassium, magnesium, and zinc.
Although yogurt is a popular food product, many people are unaware of exactly what it is.
Yogurt is a milk product that has undergone fermentation.
The lactic acid present in the milk is fermented by various bacteria.
As a result of this process, live bacteria -- lactic acid bacteria -- are present in the yogurt, frequently the same bacteria that are present in the body's gastrointestinal system.
The lactic acid bacteria snthesize or produce various products including an enzyme called lactase.
Lactase decreases the amount of lactose, a sugar, present in the yogurt which is helpful to people who are lactose intolerant.
Individuals who are lactose intolerant, and there are many, have difficulty digesting lactose.
As a result, they develop symptoms of excessive gas production, feel bloated and have diarrhea and abdominal pain.
Since yogurt does not contain much lactose, it is a food people with lactose intolerance can usually consume.
It is high in calcium but the amount varies depending upon the type of yogurt.
It also contains vitamin B-12, riboflavin, potassium, magnesium and zinc.
Many contain fruit jam which adds as much as seven teaspoons of sugar per cup.
The amount of calories per cup of yogurt varies depending upon the type of yogurt.
Some yogurts, such as low-fat coffee yogurt, contain as much caffeine as a half a cup of brewed coffee.
Yogurt is generally a nutritious food product, but what is added to it may vary.
