Reader Question: "Is eating yogurt daily good for the average person?"

The short answer: Maybe... It depends... On a lot of things... like your personal biochemistry, the source of the dairy, and the ingredients in the yogurt to name a few. The longer answer: First let’s take a VERY short look at the history of dairy as a human food. Really we should not be able to digest milk beyond when we should be weaned from our mothers, by about the age of six. Waaaaaaay back during when human tribes were far flung around the globe and not in regular contact with each other, the northern European tribes, Egyptians, and other groups who were domesticating cattle began to exhibit a genetic mutation that left the gene responsible for making the lactase enzyme in the “on” position. This meant that these humans could continue to digest the lactose sugars in milk beyond childhood. The tribes who were not exposed to this mutation have maintained their “normal” adulthood lactose-intolerance. This is why many African and Asian populations are largely lactose-intolerant. Today this is changing as genetic material is rapidly mixing as we become a more global society. 



Dairy as a food has changed radically in the last 150 years with the advent of pesticides, industrial confinement dairies, growth-hormone injections, antibiotics and pasteurization. Let’s just look at pasteurization for a minute. This process was largely adopted in an effort to stop the spread of diseases such as typhoid, scarlet fever, and tuberculosis that sickened many people during the early 1900s by way of ingesting contaminated milk products. Pasteurization is now mandated in many states and dairy products must meet certain national standards to cross state lines. The two main pasteurization techniques subject raw milk to temperatures exceeding 161F for 15 seconds (high-heat-short-time; HTST) or 280F for 2 seconds (ultra-high-heat; UHT). The UHT or “ultra-pasteurized” process is becoming more popular so now you can even find milk in tetra-packs on unrefrigerated grocery shelves. 



What does this do to the milk? Consider that milk proteins, primarily whey and casein, are fragile. When they are subjected to high heat, vigorous shaking, or high-speed blending, they begin to break apart quickly into random amino-acid groups or singles in a process known as “denaturing”. The body likes to receive intact un-denatured proteins so it can break them apart into the puzzle pieces it knows how to use. Highly processed dairy products create dubious protein bioavailability for our human systems. In addition, the high heat damages the fats found in milk, including beneficial conjugated linoleic acid (CLA) which helps trigger healthy body composition balance (i.e. supports lean mass and helps the body let go of extra body fat mass). 



Keep in mind that toxins tend to travel most effectively up the food chain in fats (the subject another upcoming post) and you’ll want to avoid any non-organic dairy product as well.



So back to the yogurt question: Yes, unflavored yogurt made from whole, organic milk from grass-fed, hormone-free cows can be healthy for people who are not allergic to dairy or lactose intolerant. Highly-processed, denatured, fat-free, "squeeze-pack" yogurts with loads of sugar or sugar-substitutes and carrageenan thickeners? not so much (and especially not for children). Get the good stuff. Get as close to milk from a happy, healthy Bessie as you can. Get REAL.
