DOES MILK DO YOUR BODY GOOD?

Some experts say it is a health hazard. Other say it is the most nutritious food you can find. We investigate all the claims about milk to find out if you should have a glass of milk.

“Milk is a deadly poison,” according to the Dairy Education Board, in the US. In fact, if you peruse this special interest group’s website, www.not-milk.com you will find dozens of articles about the purported evils of this popular beverage.

One claim, for example, is that milk from cows contains cancer-causing hormones and dairy industry money had kept the fact bottled up. All of which may leave you second-guessing your next sip.

However, as a nurse, I have found out that most men thrive on milk, whether their goal is to lose fat or build muscle. So, to be sure it is safe, I have investigated all the anti-milk claims, sifting through the research while also turning a critical eye to pro-milk propaganda. After all, the only agenda I have is my client’s health. The result: all your milk questions, answered.

IS MILK REALLY A FAT-BURNING FOOD?

Maybe. In a 6-month study, University of Tennessee researchers found that overweight people who downed three servings a day of calcium-rich dairy lost more belly fat than those who followed a similar diet minus two or more of the dairy servings. In addition, the researchers discovered that calcium supplements did not work as well as milk. Why? They believe that while calcium may increase the rate at which your body burns fat, other active compounds in dairy (such as milk proteins) provide an additional fat-burning affect. Of course, the key to success is following a weight-loss diet to begin with. After all, downing your dairy with a box of doughnuts is no way to torch your gut.

DOES IT BUILD MUSCLE?

Absolutely. In fact, milk is one of the best muscle foods on the planet. You see, the protein in milk is about 80 percent whey and 20 percent casein. Both are high quality proteins, but whey is known as “fast protein” because it is quickly broken down into amino acids and absorbed into the bloodstream. That makes it a very good protein to consume after your workout. Casein on the other hand, is digested more slowly. So it is ideal for providing your body with a steady supply of smaller amounts of protein for a longer period of time – like between meals or while you sleep. Since milk provides both, one big glass gives your body an ideal combination of muscle-building proteins.

COWS ARE GIVEN HORMONES. DOESN’T THAT MAKE THEIR MILK UNHEALTHY?

Not unless you are injecting the milk.  Here is the full story: In 1993 the US FDA approved the use of recombinant bovine growth hormone (rBGH) in cattle. This practice is resulted in greater milk production at less cost to the dairy farmer, a savings that have been passed on to you at your local market. But it has also sparked much controversy, because rBGH boosts milk’s concentration of insulin-like growth factor (IGF), a hormone that has been linked to cancer.

Unlike steroid hormones, which can be taken orally, rBGH and IGF must be injected to have any effect. That is because the process of digestion destroys these “protein” hormones. So drinking milk from hormone-treated cows does not transfer the active form of these chemicals to your body. However, there is one ethical downside to consider. It is not good for the cows. Canadian researchers discovered that cows given hormones are more likely to contract an udder infection called mastitis.

WHAT ABOUT ANTIBIOTICS?

No one really knows. Some scientists argue that milk from cows given antibiotics leads to antibiotic resistance in humans, making these types of drugs less effective when you take them for an infection. But this finding has never been proved. If you are uneasy, you can purchase organic milk at any convenient store.

SKIM OR WHOLE?

It depends on your taste. While you have probably always been told to drink reduced fat milk, the majority of scientific studies show that drinking whole milk actually improves cholesterol levels, just not as much as drinking skim does. One recent exception: Danish researchers found that men who consumed a diet rich in whole milk experienced a slight increase in LDL cholesterol (six points). However, it is worth noting that these men drank six 8-ounce glasses a day, an unusually high amount. Even so, triglycerides – another marker of heart-disease risk – decreased by 22 percent.

The bottom line: Drinking 2-3 glasses of milk a day, whether it is skim, 2 percent or whole, lowers the likelihood of both heart attack and stroke – a finding confirmed by British scientists.

 If you are dieting, the lower-fat option is an easy way to save a few calories. When it comes to building muscle, though, whole milk may be your best choice: Scientist at University of Texas medical branch in Galveston found that drinking whole milk after lifting weights boosted muscle protein synthesis – an indicator of muscle growth – 2.8 times more than drinking skim did.
