Helen was brought to Dr. McBride’s clinic by her worried aunt. Helen was 21 years old, and was dangerously underweight and getting thinner by the day. She was a tall girl – 185 cm (over 6’ 6”) in height with a weight of 51 kg (112 lbs.). She looked emaciated, pale, her eyes were dull and her voice feeble. Her menstruations have stopped seven months ago.
Helen grew up abroad and came to England to study at a university. Helen was brought up on home-cooked wholesome meals made from fresh locally produced ingredients; fresh meat, fresh eggs and fresh whole milk constituted a large percent of her diet. She was always very healthy. When she came to England she soon developed a dislike for the processed junk diets her fellow students lived on. Short research in popular literature lead her to the idea that the ‘healthiest diet’ isa vegetarian one and a low-fat one.So, Helen started cooking her own meals out of whole grains, beans, lentils, nuts, lots of vegetables and fruit. She drank only water and fruit juices. The only fat she had was some olive oil and peanut butter. She consumed no animal foods at all and tried to eat everything organic.
After a few months on this diet Helen’s menstruations stopped and she started loosing weight. But she ‘felt well’. When she went home for a visit her family were horrified by the way she looked and contacted her aunt in England asking for help.
So, what happened to Helen? What about all the research showing that following a vegan diet reduces high blood pressure, helps to recover from diabetes and many other chronic diseases? What about cancer-treatment protocols most of which are vegan? These protocols and approaches show a record of success.
Let us try and understand the whole issue.
Thankfully, Helen stopped eating all processed foods. They are at the root of all modern epidemics of degenerative disease. Mother Nature took billions of years to design our bodies while at the same time designing all the foods suitable for our bodies to use. To have good health we need to eat foods created by Mother Nature, not man.
Mother Nature has provided us with two groups of food: plant foods and animal foods. These two groups work differently in the body and both are important to be consumed. Human beings are omnivores: we have evolved on this planet eating everything we could find in our immediate environment from both plants and animals. Let us have a look at these two groups of natural foods in more detail.
All energy on our beautiful planet gets recycled, while new energy comes from the sun. In order to capture the energy of the sun and convert it into solid matter Mother Nature has designed plants – they have photosynthesis, which converts the sunlight into chlorophyll building the plant matter. The next group of creatures on the planet to consume the energy of the sun in the form of plants are herbivorous animals – animals designed to eat plant matter. In order for herbivorous animals to digest plants and extract nutrients from plants Mother Nature equipped them with very special digestive systems, called rumen. It is very long with several stomachs full of special plant-breaking bacteria. So, it is not the cow (or any other herbivorous animal) that digests the grass but the bacteria in her rumen.
In order to consume the energy of the sun in the form of herbivorous animals Mother Nature has designed the next group of life – predators. Wolves, lions, tigers, foxes, etc., which cannot digest plant matter because they are equipped with a very different digestive system. Human digestive system is similar to the gut of predatory animals: we have only one small stomach with virtually no bacteria in it. In fact our human stomach is designed to produce acid and pepsin, which are only able to break down meat, fish, milk and eggs. As the food moves out of our stomachs into the intestines, pancreatic enzymes and bile are added to the mix to break down the food further and absorb it. In short our digestive systems have been designed to best cope with animal foods. Early mankind knew that the most nourishing foods for them came from animals; they would only eat plants as a supplement to meat or when animal foods were in short supply.
But what about all the research published in popular nutrition books, which shows that plants are full of nourishment? Yes, when we analyse different plant foods in a laboratory, they show good amounts of vitamins, proteins, fats and minerals. Confusing? Why? Because, in a laboratory we can use all sorts of methods and chemicals for extracting nutrients from plants: methods, which our human digestive system does not possess. Human gut has a very limited ability to digest plants and to extract useful nutrients from them. Early mankind knew that plant foods are hard for humans to digest, that is why all traditional cultures have developed methods of food preparation to extract more nutrition from plants and to make them more digestible, such as fermentation, malting, sprouting and cooking. Unfortunately, in our modern world many of these methods have been replaced with profitable commercial products from the food industry.
If we cook and prepare the plant foods properly, can’t we live on them? That is exactly what Helen tried to do: she prepared all her food at home from natural plant ingredients. She cooked rice, oats, quinoa and buckwheat, she made her own bread, she cooked beans and lentils, she snacked on nuts and fruit and consumed lots of vegetables. Why did she get into trouble? Let us see.
Human body (without water) is largely made out of protein and fat (almost half and half), these are the ‘bricks and mortar’ from which your bones, muscles, brain, heart, lungs, liver and all other organs are made. Laboratory analysis of plants and animal foods show that the best protein and fat for human physiology comes from animal foods. The amino acid profile of animal protein is correct for the human body, while amino acid profile of plant-derived proteins is incomplete and unsuitable for human physiology. The same with fat: animal fat has the right fatty acid composition for human body to thrive on, while plant oils are unsuitable. So, when it comes to FEEDING your body and BUILDING your bodily tissues and structures animal foods are the best and the only suitable ones.
Human body has a wonderful process, which goes on from the moment of conception till death, called Cell Regeneration. Cells in your body constantly get old, die and get replaced by newly-born cells. This way the body maintains itself, rejuvenates itself and heals any damage. In order for your body to give birth to those baby cells to replace the old ones building materials are needed – proteins and fats. The best building materials to feed your cell regeneration process come from animal foods: meats, fish, eggs and dairy. Growing children need large amounts of building materials for their bodies not only for cell regeneration but for growth, so animal foods must be a very important part of their diet. Apart from feeding, animal products provide the body with energy; in fact the best source of energy for most cells in your body is fat.
One of the hungriest organs in the human body is the brain: it ‘sponges up’ around 25 – 45 % of all nutrition floating in your blood. Your body spends a lot of effort on feeding the brain 24 hours a day, every day. Contrary to popular beliefs there is much more your brain needs than just energy in the form of glucose; it is a physical organ and it requires feeding its own cell regeneration processes with good quality protein and fat.
The brain is a very fatty organ, so it requires a lot of good quality fat to be fed properly. On top of that your brain manufactures neurotransmitters, hormones and hundreds of other active molecules, which are largely proteins; the brain needs building materials to make them from. Again the best building materials to feed your brain come from animal foods. In the clinical practice Dr. McBride sees the degeneration of the brain function in people on purely vegan diets: first the sense of humour goes, the person becomes ‘black-and-white’ in their thinking and behaviour, the sharpness of the mind goes, memory suffers, depression sets in and other mental problems follow. These are all the signs of a starving brain.
