Dairy, Good or Bad...What does the Research have to Say?

I'm often asked my opinion on several topics Dairy being one of them.  If I do give my opinion which is rare, It is usually intertwined with the research that I'm citing and that, it's not my opinion at all I'm just parroting what the research has to say.  

I look forward to reading any feedback and/or contrary research for my edification.  So please feel free to email me at drkosmo@gmail.com  I have also cited many references. Dr. Willits appears to have done the most Research on the topic that I could find. He states.

1. Milk doesn't reduce fractures.(i) Contrary to popular belief, eating dairy products has never been shown to reduce fracture risk. In fact, according to the Nurses' Health Study dairy may increase risk of fractures by 50 percent.

2. Less dairy, better bones. Countries with lowest rates of dairy and calcium consumption (like those in Africa and Asia) have the lowest rates of osteoporosis.

3. Calcium isn't as bone-protective as we thought. Studies of calcium supplementation have shown no benefit in reducing fracture risk.Vitamin D appears to be much more important than calcium in preventing fractures the best source is the sun...

4. Calcium may raise cancer risk. Research shows that higher intakes of both calcium and dairy products may increase a man's risk of prostate cancer by 30 to 50 percent.(iii) Plus, dairy consumption increases the body's level of insulin-like growth factor-1 (IGF-1) -- a known cancer promoter.

5. Calcium has benefits that dairy doesn't. Calcium supplements, but not dairy products, may reduce the risk of colon cancer.  Dark greens are high in usable calcium.

6. Not everyone can stomach dairy. About 75 percent of the world's population is genetically unable to properly digest milk and other dairy products -- a problem called lactose intolerance.  dairy also contains a very difficult to digest protein, sodium caseinate a very poor quality protein.

Based on such findings, Dr. Willet has come to some important conclusions:

• Everybody needs calcium -- but probably not as much as our government's recommended daily allowance (RDA) and calcium from diet, including greens and beans is better utilized by the body with less risk than calcium supplements.

• Calcium probably doesn't prevent broken bones. Few people in this country are likely to reduce their fracture risk by getting more calcium.

• Men may not want to take calcium supplements. Supplements of calcium and vitamin D may be reasonable for women.

• Dairy may be unhealthy. Advocating dairy consumption may have negative effects on health.

If all that isn't enough to swear you off milk, there are a few other scientific findings worth noting. The Federal Trade Commission (FTC) recently asked the UDSA to look into the scientific basis of the claims made in the "milk mustache" ads. Their panel of scientists stated the truth clearly:

• Milk doesn't benefit sports performance.

• There's no evidence that dairy is good for your bones or prevents osteoporosis -- in fact, the animal protein it contains may help cause bone loss!

• Dairy is linked to prostate cancer.

• It's full of saturated fat and is linked to heart disease.

• Dairy causes digestive problems for the 75 percent of people with lactose intolerance.

• Dairy aggravates irritable bowel syndrome.

Simply put, the FTC asked the dairy industry, "Got Proof?" -- and the answer was NO!  Plus, dairy may contribute to even more health problems, like:

• Allergies (vi)

• Sinus problems

• Ear infections

• Type 1 diabetes (vii)

• Chronic constipation (viii)

• Anemia (in children)

Due to these concerns, many have begun to consider raw milk an alternative. But that isn't really a healthy form of dairy either ...

Yes, raw, whole, organic milk eliminates concerns like pesticides, hormones, antibiotics, and the effects of homogenization and pasteurization -- but to me, these benefits don't outweigh dairy's potential risks.

From an evolutionary point of view, milk is a strange food for humans. Until 10,000 years ago we didn't domesticate animals and weren't able to drink milk (unless some brave hunter-gather milked a wild tiger or buffalo!).

If you don't believe that, consider this: The majority of humans naturally stop producing significant amounts of lactase - the enzyme needed to properly metabolize lactose, the sugar in milk -- sometime between the ages of two and five. In fact, for most mammals, the normal condition is to stop producing the enzymes needed to properly digest and metabolize milk after they have been weaned.

Our bodies just weren't made to digest milk on a regular basis. Instead, most scientists agree that it's better for us to get calcium, potassium, protein, and fats from other food sources, like whole plant foods -- vegetables, fruits, beans, whole grains, nuts, seeds, and seaweed.

So here is my advice for dealing with dairy.

6 Tips for Dealing with Dairy

• Take your Cow for a Walk. It will do you much more good than drinking milk.

• Don't rely on dairy for healthy bones. If you want healthy bones, get plenty of exercise and supplement with 2,000 IU of vitamin D daily. The Sun is the best source but the USDA does not list it.

• Get your calcium from food. These include dark green leafy vegetables, sesame tahini, sea vegetables, and sardines or salmon with the bones.

• Try giving up all dairy. That means eliminate milk, cheese, yogurt, and ice cream for two weeks and see if you feel better. You should notice improvements with your sinuses, post-nasal drip, headaches, irritable bowel syndrome, energy, and weight. Then start eating dairy again and see how you feel. If you feel worse, you should try to give it up for life.

• If you can tolerate dairy, use only raw, organic dairy products. I suggest focusing on fermented products like unsweetened yogurt and kefir, occasionally.

• If you have to feed your child formula from milk, don't worry. The milk in infant formula is hydrolyzed or broken down and easier to digest (although it can still cause allergies). Once your child is a year old, switch him or her to real food and almond milk.
