Milk myths and vegan propaganda

url

You know that I’m no great lover of milk. I have written a number of times about chocolate milk (for my newer readers here are just a few of those posts: The chocolate milk and exercise myth, Is chocolate milk essential to good nutrition?, Don’t cry over chocolate milk). Chocolate milk is delicious because it is essentially a liquid candy bar. White milk is definitely a better choice from a nutrition stand-point. Personally, I loathe a glass of milk (my mum can vouch for my life-long efforts to avoid milk consumption) but I’m more than happy to put it on my cereal, add it to a smoothie, or use it in a recipe. Despite my distaste for milk as a beverage, and a food group, I still think that it has nutritional merits and that people who enjoy it should not be discouraged from drinking it. Putting my personal opinions about milk aside, I was frustrated to read the article 5 Ridiculous Myths About  Cows Milk this week.

Myth 1: You need cow’s milk to get calcium

It’s true, you don’t need milk to get calcium. There are plenty of other food sources of calcium. However, the statements that, “the calcium contained in cow’s milk is barely absorbable to the human body” and, “The most calcium-rich foods on the planet comes from plants, especially leafy greens such as kale, spinach, and broccoli” are not entirely true.

It seems that calcium absorption from milk products and kale is similar (1) – about 30-35%. Spinach is notorious for being loaded with calcium that is not bioavailable to us – about 5% (2).

Myth 2: Cow’s milk will give you strong bones

Contrary to the claim that cow’s milk will actually result in weakened bones, there is no reason to believe that it will hinder bone strength. Although, there’s also no reason to believe that milk consumption will strengthen bones either. The best way to ensure strong bones is to engage in regular exercise, especially strength training.

Myth 3: Cow’s milk isn’t cruel

Here’s where the article really goes off the rails. The discussion of veal is irrelevant to the discussion of milk. Dairy cows and cows raised for meat are not one and the same. Yes, we have all seen the recent mistreatment of dairy cows. I’m willing to bet that this was the exception and not the norm. Just like humans, cows need to be relaxed to produce milk. Most dairy farmers treat their cows with love and respect.

Myth 4: Cows need to be milked

I can’t argue with this one. Obviously this is a matter of supply and demand. If cows are regularly milked, they will continue to produce milk, even without calves to feed. If cows are not regularly milked, and do not have offspring to feed, they will cease milk production. I’m not sure how this factors in as an argument against milk consumption by humans.

Myth 5: Cow’s milk is for humans

The argument is that cow’s milk is intended to feed baby cows and that no other species consumes the milk of another. Honestly, there was a time when I was like, “yeah, this makes sense. It’s so unnatural for us to drink milk from another species.” Then I thought about it a little more. We do A LOT of things that no other species do. Just from a food standpoint alone: we cook our food in a variety of ways, we preserve food in a number of ways, we eat at restaurants, we combine ingredients to make a recipe… Just because no other species does these things doesn’t mean that we should cease doing them as well.
