I would like to know the truth about milk as a nutrition. I have recently met several people how were strongly against milk consumption saying that milk contents were hard to digest and had no nutrition value. In childhood I was told that milk is essential to people of all ages and was really important as a contrapoison (antidote) in some cases. Milk contains fat, cholesterol which is not really good for any one, but also it has calcium and others minerals which are necessary for in humans. This is all what I know about it. Is there any body to tell me more about milk in a simple language with a conclusion how good it is or not as a nutrition. Thanks

It isn't as simple as that.
1. Some cholesterol is necessary for good health.
2. Most of the body's cholesterol is manufactured from ingested
carbohydrates (sugar, etc.).
3. Whether cholesterol is good or bad is apparently determined
by what type of protien it is bound to - low density lipoprotiens are
the baddies, high density ones are the good guys.

Low-fat milk is a rather nutrition dense food. That means that, for the calories, it provides a lot of nutrition. There are a few caveats to be attached to milk: 1) Many adults, and some children, are unable to easily digest the carbohydrate component of milk - lactose. This is refered to as lactase insufficiency, lactase being the enzyme that breaks lactose down to it's component simple sugars: glucose and galactose. The result is gas and diarrhea from the intestinal bacteria feasting on the unabsorbed lactose. Lact-Aid is either a product that can be added to milk or the milk itself with the product (don't remember which) that will "pre-digest" the lactose. 2) Cow's milk, of any fat content, is not a good substitute for human milk. If my memory serves me correctly cow's milk is too high in protein for human babies. 3) With the exception of skim milk all milk contains cholesterol and saturated fatty acids. Most authorities agree that adults should avoid these in their diet and many nutritionists feel that children should have a low intake of cholesterol and saturated fats. 4) Many teens drink excessive amounts of milk to the exclusion of other foods. This is probably better then loading up on candy and chips but can result in an unbalanced diet. -- Jerry Natowitz Bell Labs - HR 2A-214 201-615-5178 (CORNET 295-5178) ihnp4!hropus!jin

The body utilizes in any given day just short of a gram of cholesterol. Of that about 600 mg is synthesized by the body itself, primarily in the liver. The remaining 300 mg is extracted from the diet (that's an american diet). There is indeed quite a bit of fat and cholesterol in milk, and one would EXPECT that serum cholesterol (the only number that really matters) would rise with milk intake. It doesn't. It actually goes down a very small amount. Paradoxical yes, but biology is stranger than nature. And milk is a complex homogeneous suspension. Oh, this is not without precedence. It is generally agreed that high sodium intake causes increased blood pressure in suseptible humans. At least that's true for Sodium Chloride (normal table salt). However, Monosodium glutamate (one molecule Sodium, one molecule glutamate) causes a slight fall in blood pressure. Again paradoxical, and please no flames about Chinese Restaurant Syndrome. While I'm at it, let me talk about Fish Oils. The claims of these new wonder supplements (that is omega-6 fatty acids) is that they lower serum cholesterol. They don't. The Eskimos have a high serum cholesterol. What they lack is the expected mortality rate from cardiovascular disease that generally goes with a high serum cholesterol. There's a subtle difference there, and I thought I'd point it out. Furthermore, it is not generally appreciated that these pills are fatty acids. And the daily dose of these supplements provides about 300 calories. So one wonders if any of these studies can really be applied to the american population in other than a clinical trial situation (where those 300 calories replaces 300 calories of other fat, instead of supplementing it.) -- Craig Werner (MD/PhD '91) !philabs!aecom!werner (1935-14E Eastchester Rd., Bronx NY 10461, 212-931-2517) "If I don't see you soon, I'll see you later."

In response to one of the points that have been made, namely, avoidance of cholesterol in the diet : As usual, there are no simple answers. A friend of mine in the medical profession tells me of some research that seems to show that people with abnormally low cholesterol levels should be considered high cancer risk. One perhaps should balance, therefore, the risk of a (usually) lingering, painful end against the risk of a heart attack (painful, but probably quicker) :-(. = = = = = = = = = = = | Philip J.
