      I was discussing with a colleague a diet he is doing called the Paleo diet, which is based on eating the stuff that our hunter gatherer ancestors would have available (meat, and fruit mainly) on the assumption that this is the diet we evolved to eat, and so is therefore better.

      I argued that wheat and dairy farming have been around for 1000s of years, so we’ve had plenty of time for our bodies to evolve to eat these (or rather the people who couldn’t stomach them die out). He countered that human evolution stopped with anatomically modern humans.

      Who is right?

      Why would he think that humans are exempt from evolution?

      An example of dietary evolution is persistance of lactase production in dairy-use populations.

      he just thinks human evolution has been negligible since we were hunter gatherers – and therefore the paleo diet (no milk or cereals) must be better suited to us. I do see the simple appeal of that logic.

      Great information… really appreciate this forum.

      So as agriculture adjusted nutrients levels in food (not always in a predictable or single-nutrient way, there would be selection for those best able to mobilize and use those nutrients. As our diets have changed, it’s likely that our abilities to best use those diets has changed as well.

      Google "skeptic paleo diet" and you’ll find lots of cool stuff that explains this nonsense.

      The claim the human evolution has stopped is completely false. Humans to this day continue to evolve, for example there’s the recent mountain natives who have larger lungs because they’ve lived in an elevated area but have only been living there for less than 300 years. That’s pretty fast adaptation/evolution if you ask me.

      The paleo diet however is the best diet to turn on the body’s natural fat burning mode, not because it’s what hunter gatherer’s ate but rather because it’s high in fat, protein and low in carbs. The exact macro combination to put the body into it’s fastest fat burning mode. It’s not a healthy diet to exceed longer than a month though.

      Here’s a better explanation of the Paleo diet: What’s the Paleo Diet?

      Here’s a Paleo diet broke-down and its nutrition explained: Paleo Diet Foot List and Breakdown

      Human dietary has remained almost the same since the agricultural revolution, but the human body hasn’t been put to the test yet. What if food was poisoned with a slow-killing mineral. Overtime many of years, the body’s digestive system would evolve because if not humans would face certain extinction. We haven’t evolved because we haven’t had a need too, yet…

      Hm, u know, i find counting calories a very boring and annoying routine. Dont you? I got so sick of always tracking my data that one time bought, here are some phen375 reviews and stopped worrying. My friends are all dont believe in diet pills but honestly, you’ll never know until you try it. But as for me i think meat cant be diting enough. We can absorb all the needed vitamins through froots and vegetables easily. And i highly doubt that our ancestors were dieting much

      personally i’ve found that eating no carbs, high protein and high fat, is the best macro diet to follow. basically you only eat foods that match that criteria! Dieting can be a pain if you’re micro dieting, cooking and counting calories sucks. So just macro diet and eat as you please but only stuff with those macro requirements!

      They say not to give chocolate to a dog… But if you give small amounts to a puppy, that same puppy will grow up to be a dog immune to the toxins in the chocolate. This is not really evolution in my book, it is how bodies of humans and animals adapt. It is adaptation. We didn’t need to evolve anything to be able to digest milk, our bodies just needed to adapt to it. If that makes sense.

      You can’t make a dog "immune to toxins" by giving them chocolate as a puppy. Please do not feed chocolate to dogs.

      I believe that our ancestors except for eating whatever being in their reach, exchanged know-how with each other concerning the positive results of each diet. e.g a diet that produced little stamina, poor nails, weak muscle etc was prompt to be abandondoned and be replaced with another one (or elements of many others) that would help our race to prevail. People just had some clues of common ingredients in different foods but acted with wisdom by categorising their common results/impact, forming super diets that protected our species and aided surpass its vulnerable nature. The fact that such ingredients are being isolated -or even bottled- today by food and pharmacy industry and sold as chemical diets isn’t really strange but just an evolution of this longlasting selection process.

      I ‘m really confused reading all that stuff. Is there any approach with common approval? Do we currently evolve? Probably yes. Our foods contain parts of our technology and medicine, therefore creating a new super-immune or super-vulnerable species.
