I wanted to talk about the negative health-consequences of dairy consumption early on in my blog as I think it is a critical issue. Dairy is that ‘food’ that so many of us, whether we are coming from an animal-rights, or health perspective, find so hard to give up. If you are like I was, and you are still eating dairy, you’ve probably come up with several ‘good’ reasons to not give it up. These may include:
1. But we need dairy for strong bones!
2. But dairy cows aren’t killed, so farming them is okay….(right?)
3. I can give up milk, butter and ice-cream, but I CAN’T give up CHEESE. It tastes soooo good!
4. But I’m already not eating meat. Where will I get my protein?
5. But isn’t dairy supposed to be good for me?
A combination of my clinical experience and review of dairy research studies have led me to recommend that EVERYONE should stop eating dairy for the sake of their health. If you said to me that you would be willing to give up only one animal food and asked me which to choose in order to better your health, I would tell you dairy, hands-down. Here are some of the reasons, in response the above theoretical questions:
1: Dairy for strong bones, otherwise known as preventing osteoporosis. There is some research correlating dairy intake with supporting bone density, via its calcium content, it’s IGF-I (insulin-like growth factor) and its estrogens (the latter two also increase risk of certain cancers). Of course, dairy is meant to help grow bones: a human mother’s milk aids in the growth of a human infant, while a cow mother’s milk aids (or is meant to aid) the growth of her calf. And once the infant of a species is weaned – that’s it. No more dairy for the rest of their lives. Except for us human-folk. We like to do things differently. It is interesting to note that the nutritional composition of human vs cow milk is very different. Cow milk has 3x the protein and 4x the calcium as human milk. Why? Because baby cows double their weight in 47 days whereas baby humans double theirs in 6 months. Calves need the extra protein and calcium; humans don’t (or nature would have done things differently).
However, contrary to research suggesting that ‘cow dairy builds strong bones’, there is actually much research that shows that dairy intake (as well as a high animal-protein diet in general) increases bone loss. Here are some facts:
Countries that consume large quantities of dairy and animal products (it is hard to divide the two groups), such as Canada and the USA, have a significantly higher incidence of osteoporosis than countries who have a much lower dairy intake. (click here for research article)
Pasteurized dairy, along with all animal foods, is acidic. The main way the body buffers acidity in the blood is by using calcium. And where do we find 99% of the calcium in our bodies? In bone. So, when we eat a high animal diet, including dairy, we force our physiological selves to leach calcium from bone in order to maintain a neutral blood pH. That calcium is then excreted in our urine.
I think it is interesting to note that Native Inuit, who have the highest calcium intake in the world, (above 200o mg per day from fish bones) and who also have the world’s highest protein intake at up to 400 grams per day, also have the highest incidence in the world of, you guessed it, osteoporosis.
Conversely, “The African Bantu consumes an average of 350 mg of calcium per day (current recommendations for Americans is about 1000 mg per day) yet do not have calcium deficiency, seldom break a bone, and rarely lose a tooth. (Plenty of Bantus live past age 65.) They consume very low-protein diets with sufficient calories. Osteoporosis among the Bantu is very rare until they migrate to the United States and begin to consume a typical, protein-laden American diet.” (See Reference)
Also worth mentioning is that no health organization or researcher or medical doctor has ever found, anywhere in the world, a single case of dietary calcium deficiency in a human. Never. To repeat: There has never been a reported case of dietary calcium deficiency anywhere in the world.
So, the short of it is: if you want to decrease your risk of osteoporosis, you need to decrease, or preferably eliminate your intake of dairy, and of all animal products.
2. Dairy farming doesn’t require the killing of cows. Hmmmm, I’m going to send you to my first post to explain that one. Also check out this link.
3. Yeah, cheese and maybe some other dairy products taste good – to some of us. So do sugar and deep fried potatoes, but no one recommends these as a healthy part of your daily diet. Although I don’t think there is evidence to prove this, I believe that there is some substance, in cheese particularly, that acts in an addictive kind of way in our bodies, making us believe, both emotionally and physiologically, that we ‘need’ it; that we ‘must have it’. As with any addiction, the best way to get over it is to give it up for an extended period of time. I find that three to four weeks is a time frame where-in most people can get over their craving/addiction/over-arching desire for a given food.
It also helps, when trying to give up your taste for dairy, to think of the other factors, such as the health consequences, and the animal-farming issues that I’ve already mentioned above, and those I’ll mention below. For me, if I ever have a hankering for a dairy-laden dessert, for example, I just need to replay in my mind the video of a downed dairy cow, heading for slaughter, too sick to stand, so instead being bulldozed over concrete to her death. Does the trick every time.
4. Ah, the great scheme of not enough protein. I believe that Atkins will go down in history as the guy who really f-d up our bodies by telling us we need to shove truck-loads of animal protein down our gizzards. I definitely need to do a separate blog on this topic, but let me touch on a few points now:
As mentioned above in question #1, too much protein has a negative affect on our bone density. The blood- acidity related to animal protein ingestion is also linked to cancer growth. Seems cancer cells dig an acid-environment to thrive. Too much protein is a burden on the kidneys and can lead to kidney/urinary tract disease. High protein/low carbohydrate diets are also linked to increased risk of heart disease and colon cancer.
Protein is available in abundance in plant food. The average person needs only around 50-60 grams a day (less for some, more for athletes). I’ll address this more in a later post, but a couple of examples include: 1/2 cup firm tofu: 10 g of protein; 1 cup kidney beans: 13 g; 1 cup cooked oats: 6g; 2 cups raw kale: 4 g; 1 cup mashed banana: 2 g; 2 tbsps peanut butter: 8 g; 1 cup cooked quinoa: 8g.
5. But isn’t dairy supposed to be good for me? I’m afraid to say that the answer is just the opposite. Over my years of practice, I have seen dairy, more than any other food, be the cause or contributing factor to a long list of symptoms and conditions. Here is a partial list:
– Skin conditions, including hives, eczema, psoriasis
– Asthma
– Headaches, migraines
– Chronic sinusitis, sinus infections
– Ear infections (especially in infants)
– Chronic post-nasal drip
– Digestive issues: gas, bloating, diarrhea, constipation, abdominal cramps, inflammation
– Attention deficit and hyperactivity
– Seasonal Allergies
– Fibromyalgia; chronic aches, pains, body inflammation
– Edema
– Acne
There is also an ever-growing body of research correlating dairy/animal protein intake with increased incidences of: Multiple sclerosis; Type I diabetes in genetically susceptible children; Alzheimers; Heart disease; Osteoporosis (as mentioned above); Cancer and more. Here is a link to a video presentation given my Dr. John McDougall on the Perils of Dairy . It is long, but you can skip the first 15minutes as he is mostly thanking people at the conference.
The reality is that the vast majority of the world’s population is lactose-intolerant and can’t digest dairy products – it makes them sick -yet the ‘food pyramid’ and government bodies keep pushing dairy as a healthy food/drink.
We, as a society, have been marketed up the whaazoo by the Dairy Industry’s Marketing Board: ‘Milk builds strong bones’, ‘Got milk?’ and the famous white mustache on the almost as famous actors and athletes have earned these marketers their paychecks. There was a time when cigarettes were promoted for better health, too. Keep that in mind next time you reach for a cheese slice, or go to pour ‘liquid meat’ on your cereal. Yum.
Death by Dairy? Not for me, thanks. I’ll stick to dark chocolate.
