Choosing health via food – in detail

This article is not about a “diet”. I prefer to avoid the word “diet”, which often implies restrictions, sacrifice, or even deprivation. It also implies something temporary. Many people who start a “diet” lose weight and then stop. They return to their previous habits, and then they re-gain the weight. The key is to think for yourself, to be prepared to break your routines, and to modify your eating habits permanently – for your health. This can be difficult, but if you think about it, it is possible. What do you value more – your health or your habits?

If you put your health first, then weight loss is merely a side effect. The goal is to improve digestion. For health, and longevity, again the key concept is first to find or develop eating habits that are healthy for you. When you truly listen to your body, you receive messages that indicate what foods are healthy for you or not. These may or may not be healthy for your friend, family member, or neighbor. 

The difference with the ideas, methods, and recipes of this site is that you can eat as much as you want without counting calories. You can still gain health, live longer, and reach a healthy weight. This process begins in the mind – for health. It continues with a permanent change of eating habits – for your health.

Regarding health via food, my intention is to publish independently and freely on the vegan-paleo question. I tend to follow paleo eating habits myself, but I recognize that these eating habits are not healthy for everybody. Some people, possibly most of all those with blood types A and AB, may be healthy by being vegan. Other people, possibly most all those with blood type O or B, may be healthy by eating small portions of eggs, fish, or meat occasionally. This article is to present specific ideas for health via food and not to offer individual advice.


Veganism can be very healthy, even therapeutic, for some people, but not all vegans are in good health. Some vegans are gaunt, scrawny, lethargic, and almost emaciated, with sagging skin, sallow faces, and baggy eyes. Many also have uncomfortable digestion. Ask them. Tofu, peanuts, beans, lentils, chickpeas, quinoa, and cereals can be healthy sources of protein for many people, but not for everybody. Could the blood type be a factor?

For my heallth, I was a vegetarian for about two years, occasionally eating eggs, fish, and chicken, but no meat. Then I became a vegan for about six months, eating no dairy nor animals. I attended some of the local vegetarian society meetings. Some vegans are particularly vocal at these meetings about their ideas and philosophy. I agree with the pacifist philosophy and the idea of living in harmony with life on earth.

I read of the various possible nutrient deficiencies that vegans can have, such as protein, iron, zinc, and vitamin B12. I learned to offset these possible deficiencies by eating plants that contained these nutrients, such as lentils, beets, pumpkin seeds, and miso or tempeh, respectively. I also took vitamin B12 supplements. By trial and error, I learned to cook and eat rice, tofu, lentils, quinoa, adzuki beans, buckwheat, and millet, all with vegetables. Also by trial and error, I learned to use spices and herbs, which contain minerals and vitamins.

I lost weight, but for my health, veganism stopped working for me. I started to feel pain in the knees, walking upstairs. I was not willing to die for the cause, so I made a change. I started to eat eggs again, with onions and spinach, two or three in an omelet. After a day or two, the pain in the knees went away. If I stopped eating eggs, the pain returned after a day. I repeated this experiment. I went back to eating eggs, liver, sardines, turkey, and meat, in small portions, at breakfast and often at lunch, almost every day. This works for me for my health, but certainly not for everybody. 

I am not alone, having been a failure as a vegan. Why? Many though not all vegan failures, who tried veganism and then went back to eating animals, have blood type O. Many though not all healthy, happy vegans have blood type A. This is consistent with blood type eating, according to Drs. D’Adamo and Mozzi. For my health, I have no qualms about the fact that I regularly eat eggs, sardines, turkey, and beef for my health (in the morning and at lunch, in small quantities, no more than one hundred and fifty grams per meal, or four to six ounces).

Many vegans were not born vegans, but they become vegans for spiritual or esoteric reasons. They see a unity of life on earth, and they see eating meat or even eggs or honey as violence towards other creatures on earth. They believe that this violence results in an accumulation of unhealthy spirit that they will later regret. They also point out that chickens, pigs, and cows butchered in confined animal farming operations (CAFO) are often contaminated with a steady supply of:


  • genetically modified animal feed (either corn or soy),
  • antibiotics,
  • growth hormones, and
  • painkillers.

CAFO carries risks, such as antibiotic resistance, pollution of local water, and waste processing. These animals may indeed be unhealthy to eat, compared with organic, grass-fed eggs, beef, or game if available.

In the wild, lions, tigers, and bears would all be happy to have you and me for lunch without qualms. Why should I have qualms about eating meat or eggs? “Nature is red and tooth in claw,” as the poet Tennyson wrote. Except for the Jain tradition in India, which goes back to the sixth century BC, there is no vegan tribe on earth. Even the Jains kept animals for dairy. 

Many vegans are in good health, in their nineties, and tolerant of carnivores. By looking and listening, I found that the healthiest vegans were the least dogmatic and the most tolerant of carnivores.

Vegans also run risks of nutrient deficiences, such as protein, iron, vitamin B12, and zinc. Again, veganism can be very healthy, even therapeutic, for some people, but it is not healthy for everybody all the time.

If you have blood type A or AB, if you eat red meat, why not at least try to exclude the meat, or else try veganism – for your health? Try it for one to three weeks, and see how you feel.

Blood type A recipes tend to be vegan recipes, though eggs are not strictly vegan. Eggs can be a healthy source of protein for all blood types, depending on how they are raised. On the other hand, some people do not digest eggs well. Optimally, eggs you eat were produced by happy chickens eating grass, not grains, and free to roam, not confined in a cage. Many people find that being lacto-vegetarian, eating eggs  and goat or sheep dairy, is healthy for them. These people tend to have blood type A or AB. You can often substitute tofu for eggs to make them vegan recipes.

On the other hand, if you are a vegan, if you have blood type O, if you are unhealthy, feel tired or weak, or have uncomfortable digestion, are you willing to die for the cause? Why not try eating small portions of eggs, fish, or beef, in the morning, for your health, and see how you feel?


Paleo eating habits are also known as a “caveman” or “stone age” diet. This is not a new idea. Dr. Walter L. Voegtlin MD wrote his book, “The Stone Age Diet“, in 1975, and the idea surely goes back even further. The idea is to eat how our ancient ancestors ate before agriculture, cities, and the cultivation of wheat, rice, corn, and soy. Contrary to popular belief, it does not advise large quantities of meat, fish, or eggs, merely moderate quantities, even daily. There are many misinterpreations of the paleo idea. It works for some people, but it is not for everybody. According to blood type eating, paleo is consistent with blood type O but not with blood type A. Paleo or mostly paleo eating habits work for me. I have blood type O. If you have blood type O, paleo may or may not work for you, but why not try it for a week and see how you feel – for your health, to live longer, or for weight loss? Blood type O recipes also tend to be paleo recipes. Paleo excludes grains, beans, legumes, dairy, and all refined foods. It includes vegetables, fruit, eggs, fish, meat, nuts, seeds, herbs, and spices.

omeletA few noisy paleo advocates have found that eating paleo is very healthy for them. Some of them try to impose this idea, demanding or expecting that everybody eat paleo. This does not need to be. They overlook biochemical individuality. Veganism does work for many people, but not for all. The blood type may indicate probable healthy eating habits. If you are a vegan and have blood type O, if you often feel tired or in pain, why not try paleo for a week and see how you feel? Again, “nature is red in tooth and claw,” as the poet Tennyson put it.

The following websites have paleo recipes:


To recover and to maintain health, some medical doctors recommend ketogenic eating habits. It may be useful for some people but not for everybody all the time.

Ketones are molecules of energy that are lipids, in other words fat. Ketogenic eating avoids sugar of all sorts, including sugar in red beets, carrots, bananas, apples, and pears. It is intended to avoid peaks and valleys of blood sugar and insulin. You can obtain nourishment and energy from vegetables, protein, and lipids. Eating nuts and seeds can bring more energy than fruits, grains, and cereals, though some people digest nuts better than others. Healthy fats do not make you fat. Sugar does. For details, read the book by Dr. Mark Hyman, MD, “Eat Fat. Get Thin.“. Also, be aware that the calorie theory is a myth.

For an overview of eating ketogenically read Dr. Joe Mercola – A Beginner’s Guide to the Ketogenic Diet. Ketosis is the process of making energy from lipids (nuts, seeds, oil, or fat) not carbohydrates (vegetables, fruits, or starch). You produce ketones from the lipids. You then burn the ketones for energy. Even advocates of ketogenic eating habits suggest that you use caution when you first make the switch and then occasionally alternate between ketosis and burning vegetables, fruits, or starch. 

Using mostly shredded coconut, coconut oil, nuts, seeds, chocolate, eggs, and stevia, Dr. Jockers has a list of recipes for keto snacks. Healthy nuts and seeds include almonds, walnuts, pumpkin seeds, flax seeds, and chia seeds. He also describes possible side effects of eating ketogenically.

First Do No Harm” is a touching drama that also makes the point that some doctors have used a ketogenic diet to prompt some young people to heal themselves of epilepsy.

Dr. Ron Rosedale MD was an early advocate of a high-fat, ketogenic diet for health and longevity.


Macrobiotic eating habits have their origin in Japan and ancient China. George Ohsawa became ill with tuberculosis, when he was twenty. This prompted him to retreat to the mountains and to study ancient Chinese medicine. He then changed his eating habits, according to what he read, and he healed himself. Ohsawa was a pacifist who was imprisoned by the Imperial Government of Japan and later freed.

He traveled to France, where he started to promote his ideas and methods in the form of what was later called macrobiotic eating. To describe his ideas and methods, he wrote “Zen Macrobiotics: The Art of Rejuvenation and Longevity“. It is based on the idea of a balance between “yin” foods, such as vegetables, and “yang” foods, such as grains. This idea is similar to the idea of an alkaline-acid balance. His book has his ideas and observations, including the idea that food causes illness and food can cure illness. This is not a new idea, yet it is still current today. Many other authors have interpreted his ideas.

Specifically, macrobiotic eating includes soup, seaweed, vegetables, whole grains such as rice, buckwheat, or millet, beans, soy, some fruits, and small portions of fish or seafood, with horseradish, wasabi, ginger, or daikon. Sugar, honey, molasses, chocolate, and carob are excluded from a macrobiotic eating, but sweeteners such as rice syrup, barley malt, and amazake are included. Ohsawa was not dogmatic. He recommended that each person try things for himself or herself and listen to their body. For example, some people include animal foods, such as fish, in their macrobiotic practice and others do not. For details, read more by the George Ohsawa Macrobiotic Foundation

Macrobiotic eating also became popular after the publication in 1981 of the book by Michio Kushi, “The Macrobiotic Approach to Cancer“. A summary of Kushi’s macrobiotic recommendations are here.

Ohsawa further specified: 

  1. Do not eat chemical white sugar and avoid everything that is sugared.
  2. Look for the minimum quantity of water that is necessary to your existence and that will require you to
    urinate no more than three times per day.
  3. Use the least possible amount of animal products, especially if you reside in a warm climate or if you are
    going to visit one.
  4. Avoid industrial foods, particularly those with food coloring or imported from afar. 
  5. Avoid fruit.
  6. Include sixty to seventy per cent of cereals and twenty to twenty-five per cent of well cooked or baked vegetables.
  7. Avoid potatoes, tomatoes, and eggplants (the “nightshade” family, that is Solanaceae) .
  8. Season dishes with salt and use vegetable oil in a tropical climate.
  9. Cook using French, Chinese, or Indian methods.
  10. Use no vinegar.
  11. Chew food as thoroughly as possible, on average of about thirty times each mouthful.

Macrobiotic eating habits work for many people, but they do not work for everybody. In this clear essay, Carl Ferré describes why he stopped eating macrobiotic. For my health, I usually avoid cereals and grains, except oatmeal and buckwheat porridge now and then.

green smoothie with foamGerson

Max Gerson was a medical doctor. When he was a young man, he healed himself of migraine headaches by changing his eating habits. He found he could apply his method to others, whom he promptêd to heal themselves of other maladies. He wrote a book about his experience, “A Cancer Therapy – Results of Fifty Cases“. His methods included:

  • frequent organic green vegetable juices, similar to green smoothies,
  • a high potassium/sodium balance via food, and
  • coffee enemas for rapid detoxification and stimulation of the liver.

Gerson’s ideas and methods are not accepted by the medical authorities. Some doctors question the details of pathology in his book. Others point out that nobody has ever done a clinical trial of Gerson’s methods. Gerson’s daughter, Charlotte Gerson, was a strong advocate of his methods in the form of the Gerson Institute. They are truthful enough to acknowledge contra-indications and cautions. They also explain the biological basis of Gerson Therapy. Gerson clinics operate freely in Mexico and Hungary. For more details, read the book, and decide for yourself.

Reviewing Gerson’s methods and nutritional therapy is beyond the scope of this website. Do your own research. You can see an eighty-minute review of his methods in the film Dying to Have Known. This is not an offer of services nor an endorsement of any service providers. If you have a medical condition, see a doctor. Another related film is The Beautiful Truth.


Joanna Budwig was another medical doctor with an unconventional treatment of cancer in the form of a mixture of cottage cheese and flax oil. Her book, “Flax Oil as a True Aid Against Arthritis, Heart Infarction, Cancer and Other Diseases“, describes her method. The authorities tend to have a low opinion of the Budwig method, similarly to the Gerson methods. For details, read her book, and think for yourself.

There is much controversy about the methods of Drs. Gerson and Budwig and other non-patented methods, such as small doses of apricot kernels., which may contain laetrile, also known as vitamin B17. Do your own research, and then decide for yourself. If you have a medical condition, see a doctor.

Weight Watchers

Weight Watchers appears to be a fad diet that caught on and became a marketing and financial colossus. By counting calories and applying social pressure to conform, the Weight Watchers organization tries to prompt people to eat less and exercise more. They believe in the calorie theory of weight loss. In the short-term, this method works, but most people who start a restrictive “diet” stop, and then they gain the weight again.

On the other hand, people who choose to put their health first and then to modify their eating habits can have lasting results. Nowadays, Weight Watchers appears to be more interested in selling packaged food with their label on it than in offering ideas or methods for health and long life. Recently, I noticed a package of Weight Watchers cookies in a supermarket in Belgium! The label listed ingredients that included sugar, wheat flour, and ground sunflower seeds, none of which are healthy for me. Weight Watchers appears to be a fine example of the power of modern marketing methods and publicity.
