The paleo diet is designed, to eat like a caveman. You’ll fill your plate with lots of meat, seafood, vegetables, nuts, and fruits while skipping over any grains, dairy, or legumes.
Since this movie was published, it became very popular, to argue almost every human behavior like that:
“Some 10,000 years ago our ancestors were living and eating in that way …
… and that’s why you should act as the cavemen did.”
The caveman argumentation, that our digestion system works as it does, because of cavemen’s eating habits, is simply idiotic. Because our body replaces almost all cells within 3 years. Genetically we have with a caveman as much in common as with a cockroach! And our digestion system is able to adapt to new eating habits in a much shorter time. Try it out: Go to a third world country, and eat local food. You might experience diarrhea in the first week. And after that it is fine, to eat the local food, which is prepared at low hygienical standards and does not get stored in a refrigerator. You will experience, that your digestion system has adapted itself to it in less than 10 days.
Paleo Diet – high in protein, and fat, but low in carbs
The Paleo Diet implies changing from a Western diet high in packaged convenience foods to a diet that is high in protein, and fat, but low in carbs, grounded in-home cooking, and unprocessed foods. It has several benefits. You may lose weight and improve your heart health, and due to that your life expectancy.
Rich in Nutrient-Dense Foods
The paleo diet emphasizes many nutrient-dense foods like:
- Vegetables – provide fiber, vitamins, and minerals
- Fruits – act as a naturally sweet treat and they are packed with phytochemicals
- Nuts – fill you up with healthy, satiating fats
- Seafood – packed with protein and omega-3 fatty acids
The paleo diet can lead to weight loss if there is an overall calorie deficit. Indeed, research published in 2020 has shown, that implementing a paleo diet leads to reduced body weight. It may reduce waist circumference, and BMI, similar to any other type of slim-diet.
A 2019 meta-analysis in Advances in Nutrition linked the outcome of the paleo diet to lower blood pressure, LDL cholesterol, and triglycerides.
How does Paleo Diet Influence Longevity?
In 2017, researchers compared people, whose diets most closely matched the attributes of a Paleo diet. They found, compared to those whose diets least matched with it, a lower risk of all-cause mortality, and lower cancer mortality.
Keep in mind, this also could be explained by a higher overall diet quality between the groups. Certainly, a group that eats more vegetables and less processed foods experience better health outcomes. Regardless of if they follow a Paleo diet or not.
Possible Benefits for Patients with Multiple Sclerosis
For people with multiple sclerosis are appreciated to consume a modified Paleo diet. The modified version follows many tenants of paleo, such as the elimination of most grains and dairy. However, this version adds an emphasis on eating nine servings of fruits and vegetables daily. And it calls for a somewhat lower intake of meat and fish.
Are there negative aspects of the Paleo diet?
The paleo diet eliminates major food groups like grains and dairy. Further, it excludes other nutritious foods like beans, lentils, and peanuts. Though it’s still possible for you to meet your nutritional needs without these foods, it’s more challenging to do so. For example, you’ll need to prioritize other sources of calcium when you cut dairy from your diet. Unless you have a medical reason, like food intolerance, to remove these foods. But there’s no scientific evidence, that excluding grains and dairy, benefits your health.
Unclear Impact on Gut Microbiome
The species and amounts of good bacteria in your digestive system. Which is also known as your gut microbiome, which can be changed by altering your diet. Traditional hunter-communities, like the Hadza tribe, have greater microbial diversity, compared to standard diet controls. Theoretically, this seems like a win for paleo proponents.
