Gluten. Dairy. Sugar.

So 6 out of 10 people are lactose intolerant? I don't believe it. I've met *one* lactose intolerant person in my whole life, and I'm nearly 40.

Here you are:

Lactose intolerance is fairly common. It seems to affect guys and girls equally. Some ethnic groups are more likely to be affected than others because their diets traditionally include fewer dairy products: Almost all Asians and Native Americans are lactose intolerant, and up to 80% of African Americans and Hispanic Americans also have symptoms of lactose intolerance. Their ancestors did not eat dairy foods, so their bodies were not prepared to digest dairy, and they passed these genes on from generation to generation.

Another:

If you're American or European it's hard to realize this, but being able to digest milk as an adult is one weird genetic adaptation.

It's not normal. Somewhat less than 40% of people in the world retain the ability to digest lactose after childhood. The numbers are often given as close to 0% of Native Americans, 5% of Asians, 25% of African and Caribbean peoples, 50% of Mediterranean peoples and 90% of northern Europeans. Sweden has one of the world's highest percentages of lactase tolerant people.

This one breaks it down statistically for you:

Approximately 75 % of Earths population is lactose intolerant for a reason, that’s because it’s perfectly natural. - See more at: http://www.collective-evolution.com/2013/04/03/over-75-of-earths-population-is-lactose-intolerant-for-a-reason-dairy-is-harmful/#sthash.h0dsgNe4.dpuf

Some people have it worse then others. While some have very mild symptoms they may not even recognize. For others, it is painful and can affect their every day life.

Neither of those are primary sources. So I still don't believe it.

Just out of curiosity, which point are you doubting? 1. Whether or not lactose intolerance exists or 2. the prevalence at which it exists?

The prevalence. Six out of ten? I've met one person in my whole life that has a problem with dairy. She used to take a pill so that she could eat cheese or ice cream.

Yeah, it sounds a bit high to me, also, but I've never researched the stats, so anything's possible.

I think that there are many who COULD be diagnosed with lactose intolerance, but are not so severely impaired that they get away with some dairy. My wife can eat most anything, until you get her a large dose of ice cream or whipped cream and then I will TESTIFY to her lactose intolerance. I know many many who are like that. I don't have any sources to post for someone to call fake, I am just suggesting that its what I have seen.

Lol! Yeah, I just don't know much about the topic. I can't say either way, really.

Selection bias.

Most white people are lactose tolerant. Most non-white people are not. The vast majority of people of Asian (especially eastern and southern Asia) or African descent are not lactose tolerant.

hmmm I eat these three "evil" foods regularly and maintain 11% body fat and have lost about 60 pounds total since I started..

OP - you are losing weight because you restricted three food groups and created a calorie deficit..

Also, are you eating zero sugar? So that means no fruit, candy, carbs, etc????

Every body is different.. Some people can not diet, eat junk and never gain.. some people can eat a donut and gain 5 lbs. You can not generalize everyone as you. Losing 30 lbs in 2 months is not that crazy depending how much there is to lose of course. From experience with a lot to lose and following a steady plan 30 lbs the first 2 months of a diet is forseeable. Its when that person only has 30 to lose total its more far fetched.

Umm actually everyone is the same…if you eat in a calorie deficit, you will lose weight. Eliminating sugar, daily, gluten has nothing to do with weight loss..it is just an idiotically restrictive way to create a calorie deficit…

Eat a donut and gain five pounds, really? So that donut has 17,500 calories in it? That would be one hell of a donut…

Also interesting. Any sources for this, or is it part of what Wendy was talking about?

Not offhand. There's lots of data out there. We read a few studies on the topic in one of my public health classes.

Did they pose an evolutionary hypothesis behind this?

Oh yeah. It came up in my genetics course too, where we looked at some analyses that identified the development of the gene in a few different places at different periods in human history. Interesting stuff.
