Men and meat is one of the stereotype that’s prominent today, dating back the the stories of prehistoric men (the hunters) going off to kill wild animals, while women (the gatherers) would hang around collecting fruits, nuts, and berries. But if you’re a someone who believes real men eat meat, then I’m here to share with you 17 science based reason why man doesn’t need to eat meat.

I grew up believing meat was the REAL source of protein, it’s what I needed to be strong. It seems meat in our culture has long been associated with strength and virility. However you might be surprised to hear that there are some very powerful and influential men who eat a plant based diet including David Haye ex world WBO, IBO & IBF heavyweight boxing champion, Bill Clinton, Al Gore, Paul McCartney, New York Mayor Cory Booker, the founder of Def Jam Records Russel Simmons, the co-founder of Twitter Biz Stone, Sammuel L Jackson, lead singer of Radiohead Thom Yorke to name but a few.

So it seems men don’t need to eat meat to succeed in sport or in life. Since I’ve been exploring the optimum diet for myself – a predominantly whole food, plant based diet. I have been finding more and more scientific evidence proving meat really isn’t a food group humans should or need to be consuming, at least from a health point of view.

In fact the American Academy of Nutrition & Dietetics, the U.S.’s oldest, largest and foremost authority on diet and nutrition, has also recognised that humans have no inherent biological or nutritional need for animals products, whether this be meat or dairy.

17 Reasons Why It’s Healthier To Avoid Meat

With that in mind, here’s 17 scientifically based reasons why you may want to consider, if you’re not already, choosing a whole food, plant based diet. As always it’s your choice what you do with this information, if anything at all.

1. Humans easily get sick if they eat raw meat, a sign that neither our stomach or our immune system is designed for meat. Real carnivores swallow their food whole, relying on their extremely acidic stomach juices to break down flesh and kill the dangerous bacteria in meat that would otherwise sicken or kill them. Our stomach acids are much weaker in comparison because strong acids aren’t needed to digest pre-chewed fruits and vegetables.

2. Humans cannot digest meat well, in the main it needs to be cooked prior to consumption. Obviously carnivores don’t or can’t cook. It wasn’t until the widespread use of fire around 300,000 years ago, that humans began eating meat on a larger scale. Biologically however, our stomachs and digestive systems are pretty much the same as 1 million years ago. We are not designed to eat meat.

3. Humans are the only primates that eat meat. Any animal can eat meat in small quantities, but no primate eats meat on a regular basis. Chimpanzees, the only other primate to eat meat (3% of diet) only eats meat when their normal plant based diet is out of season.

4. We are led to believe that essential human vitamins and minerals such as B12 and oils such as omega 3 are only found in fish and meat. The truth is, they are only present in animal flesh because of the plants or algae they consume contain them.

5. Meat is an acid forming food, which if eaten in abundance will take the blood Ph level below the optimum slightly alkaline levels of 7 – 7.45. An acidic balance of 6.9 or below will decrease the body’s ability to absorb minerals and other nutrients, decrease the energy production in the cells, decrease it’s ability to repair damaged cells, decrease it’s ability to detoxify heavy metals, make tumor cells thrive, and make it more susceptible to fatigue and illness. A blood pH of 6.9, which is only slightly acidic, can induce coma and death.

6. Vegetables, wholegrains and nuts are alkali forming, which the human digestive system can process far easier than meat. These foods are also packed with vitamin and mineral-laden water, which is more easily absorbed than plain bottled water. This allows you to hydrate the body from food and not just from drinking water.

7. Alkaline foods offer many health benefits over meat including improved digestion and less flatulence and bloating of the abdomen. Improved skin tone, as seeds, nuts and their oils are rich in the essential fats that make up the matrix of the skin, better memory, focus and concentration, as blood sugar levels tend to be regulated over a longer period of time. Improved happiness, as many of the grains satisfy the serotonin receptor sites in the gut, which in turn help to elevate mood. Greatly improved energy levels, as many alkaline foods are slow-release carbohydrates and vegetarian proteins, which help to keep blood sugar balanced more evenly. Reduced cravings for sugar, alcohol, coffee and other stimulants.

8. The World Cancer Research Fund states that vegetables and fruits protect against a wide range of cancers, including mouth, pharynx and larynx, esophagus, stomach. lung. However consuming animal protein has been linked to cancer of the bowel, colon, breast, prostate, and pancreas. According to Dr. T. Colin Campbell, the director of the Cornell-China-Oxford Project on Nutrition, Health, and the Environment, “In the next ten years, one of the things you’re bound to hear is that animal protein … is one of the most toxic nutrients of all that can be considered.”

9. People who eat a predominantly wholefood, vegetarian diet live a longer life. Humans who eat a lot of meat get heart disease, cancer, diabetes, osteoporosis, and all sorts of degenerative diseases. In defense of this carnivore animals who eat a lot of meat live healthy lives.

10. Humans need to sleep about the same amount of time as other herbivores but foods that are hard to digest, such as red meat will make you feel tired after eating because they cause your body to increase the blood flow to your stomach to be able to digest properly. This is why carnivores sleep more than we do.

11. Canine teeth do not make us meat eaters – all mammals, including most herbivores, have canine teeth. The large, fierce canine teeth of herbivores such as hippos, baboon or gorillas has nothing to do with a need to eat meat. Carnivores’ jaws move only up and down, requiring them to tear chunks of flesh from their prey and swallow them whole. Humans and other herbivores can move their jaws up and down and from side to side, allowing them to grind up fruit and vegetables with their back teeth. Like other herbivores’ teeth, human back molars are flat for grinding fibrous plant foods. Carnivores lack these flat molars.

12. During many years in India, Sir Robert McCarrison observed the varying patterns of health among different groups on the subcontinent. He noticed a striking difference in general well being and physical strength of the Sikhs in the north, who eat whole foods and fresh fruit and vegetable to people consuming a Southern Indian diet; consisting mainly of white rice and meat. His findings later tested in the laboratory on rats, showed that the Sikh diet kept the rats living longer, happier and completely disease free. Whilst the Southern Indian diet led to more disease and ill health. (source)

13. It is fairly easy for a meat-eater to become a vegetarian; it is difficult for a vegetarian to start eating meat. This is because the human digestive system has to be trained from childhood to digest meat.

14. Most humans are disgusted by dead animals. If you see a dead cat or dog or badger in the road, with its brains and entrails splattered all over, you’d be more likely to turn away rather than salivate the way a real carnivore would.

15. We consume twice as much protein as we need when we eat a meat-based diet, and this contributes to osteoporosis and kidney stones. Animal protein raises the acid level in our blood, causing calcium to be excreted from the bones to restore the blood’s natural pH balance. This calcium depletion leads to osteoporosis, and the excreted calcium ends up in the kidneys, where it can form kidney stones or even trigger kidney disease.

16. Eating meat can also have negative consequences for stamina and sexual potency. One Danish study indicated that “Men peddling on a stationary bicycle until muscle failure lasted an average of 114 minutes on a mixed meat and vegetable diet, 57 minutes on a high-meat diet, and a whopping 167 minutes on a strict vegetarian diet.” Besides having increased physical endurance, men who are vegetarian are also less likely to suffer from impotence.

17. Since we don’t have strong stomach acids like carnivores to kill all the bacteria in meat, dining on animal flesh can also give us food poisoning. According to the USDA, meat is the cause of 70 percent of foodborne illnesses in the United States because it’s often contaminated with dangerous bacteria like E. coli, listeria, and campylobacter. Every year in the United States alone, food poisoning sickens over 75 million people and kills more than 5,000.


I could have added many more scientific facts that support the argument that humans are best suited to a plant based diet, but I think these 17 points do all the talking and make it a no brainer…at least to me.

You can of course, find evidence contrary to this, but to really know you have to experiment in your own personal laboratory and find out experientially.

Personally, even though BBQ’s will never be the same again, since eating a well balanced, plant based, whole food diet, I haven’t had a cold or any illness, I’m lighter, feel healthier, have more energy and I’m running faster. That is all the evidence I need.

If you’re curious I invite you to try it for yourself. If you have any experience or views on this topic it would be great to hear them. We are all here to learn from each other.
