• Vegan Diet and Athletic Performance

  A 2007 study shows the results of a vegan diet on a sedentary group of subjects. This group is compared with committed long-distance athletes and sedentary omnivores.

  The athletes and the sedentary vegans were matched on their BMI.

  Long-distance slim athletes who ran an average of 48 miles (77 km) per week for 21 years had a blood pressure a significant 17% higher than sedentary vegans.

  The authors' conclusions are that long-term consumption of a low-calorie low-protein vegan diet or regular endurance exercise training is associated with low cardiometabolic risk. Moreover, our data suggest that specific components of a low-calorie low-protein vegan diet provide additional beneficial effects on blood pressure.

• Egg Consumption, B12, Lutein and Zeaxanthin

  B12 is a group of cobalt-containing vitamins. Hydroxocobalamin and cyanocobalamin are synthetic forms of vitamin B12. The two forms of vitamin B12 naturally occurring in foods are methylcobalamin and adenosylcobalamin. These forms are biologically equivalent.

  B12 is produced by a number of different species of bacteria which is found in the soil, on the surface of some plants and some red and green algae.

  Lack of vitamin B12 can have serious consequences as does high levels of homocysteine. Determining the status of vitamin B12 and homocysteine can be difficult and can be determined by measuring serum vitamin B12, homocysteine and methylmalonic acid (MMA).

  A number of products contain riboflavin, pyridoxine, folate, B12 and methionine way in excess of dietary requirements in an attempt to resolve B12 metabolism problems.

  Many magnesium supplements contain pyridoxine which is usually unnecessary and possibly detrimental.

  Vitamin B12 is not made by plants or animals but by microbes. In today’s world, the water supply is commonly chlorinated to kill bacteria. We don’t get much B12 in the water, we also do not get much cholera.

• Egg Consumption and Diabetes

  A number of popular authors and websites advocate eating eggs as a way of preventing type 2 diabetes. However, this is not substantiated by the evidence. To assess the impact of egg consumption on type 2 diabetes in China, a survey was performed among 2849 adults in Jiangsu Province, China. Jiangsu is a coastal Chinese province north of Shanghai.

  There are many more medical journal articles that associate egg consumption with a greater risk of type 2 diabetes.

• Historical Advocates of Plant Based Diets

  Whilst they are in the minority of the general population, there have been advocates for diets devoid of animal products for centuries in populations such as ancient Rome and the Italian Renaissance.

  In The Republic, Book 2, Plato describes a “rustic picture” of a way of life. The inhabitants “spend their days in houses which they have built for themselves; they make their own clothes and produce their own corn and wine. Their principal food is barley-meal and flour of wheat, and they drink in moderation. They live on the best of terms with each other, and take care not to have too many children. […] They will have salt and olives and cheese, vegetables and fruits, and chestnuts to roast at the fire.”

  Plato continues that those “who want the comforts of life”, will create a state where “living in this way we shall have much greater need of physicians than before. […] Then a slice of our neighbours’ land will be wanted by us for pasture and tillage, and they will want a slice of ours.”

  Sotion of Alexandria was a 1st-century Roman stoic philosopher who is best known as a teacher of Seneca the Younger.

  Sotion believed that avoiding animal flesh was beneficial for the soul and body and that killing of animals is immoral.

  Some 500 years later, in Plutarch’s Morals. Vol. V, Plutarch writes at great length against the mistreatment, exploitation and killing of animals.

  “But for the sake of some little mouthful of flesh, we deprive a soul of the sun and light, and of that proportion of life and time it had been born into the world to enjoy.”

• Brief Overview of WFPB Diets

  Humans (or apes) did not evolve to eat any animal-derived products. Chimpanzees are the most omnivorous of all the apes and derive 5% of the diet from animals – mostly live termites which we do not find very appealing.

  On the right panel of every page of my website, there is a green “Videos” button with several videos explaining why a whole-food, plant-based nutrition works.

  If you view them it will show what is possible. Consider Katherine Lawrence story. She cured her endometriosis (which has the same cause as breast cancer) within 7 weeks by changing what she ate.

  Dr. Tony Sattilaro cured his aggressive cancer. After 10 years, he decided he was cured and he could revert back to his old diet. It did not work.

• Ruth Heidrich, Hawaiian Athlete and Breast Cancer Reversal

  At the age of 47, Ruth Heidrich was diagnosed with breast cancer. The cancer had spread throughout her breast and into her bones and one lung. The prognosis was not good.

  As a result of a 1982 study instigated by Dr. John McDougall, Ruth commenced a low-fat, vegan diet without chemotherapy, radiation or hormone blockers. The results of the dietary change were profound and the cancers were completely reversed.

• Antimicrobial Resistance, Antibiotics and Endometriosis

  In a video (available from my website), Neal Barnard tells the story of Katherine Lawrence who was an Air Force officer working as an aerospace engineer. In 2003, she was one of the first group of people in Iraq, building air bases.

  Cheese was one of her favourite foods, so when she returned from Iraq she devoured large quantities of cheese and cheese dishes.

  As a result she gained a substantial amount of weight and started getting pain in her abdomen that become much worse over time. A doctor performed a laparoscopy – the body is examined through a scope inserted into an incision below the belly button. This resulted in a diagnosis of endometriosis.

  Her doctor stated that her only option was a hysterectomy – an operation that removes the uterus and in this case the ovaries and fallopian tubes.

  Before the operation, Katherine removed all animal products and started consuming a low-fat diet in an attempt to control the severe pain that she was suffering. She started to feel much better. Six weeks later, she had her procedure performed on the appointed day. The doctor opens her up and an hour later Katherine woke up in the recovery room.

  Katherine's endometriosis had gone.

• Gut Bacteria, TMAO and Whole-food, Plant-based Diets

  It is well established that microbes in the intestines are essential for the breakdown of complex carbohydrates, the production of short chain fatty acids and synthesis of vitamins. More than 1000 different species have been identified. Despite the vast number of bacteria species and people, there are only two types of bacteriological ecosystems in the gut (enterotypes).

  Enterotype 1 dominated by Bacteroides genera bacteria which is strongly associated with high-fat, high-protein, animal-based diet.

  Enterotype 2 dominated by Prevotella genus bacteria which is associated with high-fibre, plant-based diets.

  Microbiome composition changed within 24 hours of initiating a high-fat/low-fiber or low-fat/high-fiber diet. However, it takes a longer period of time to change the enterotype from one state to the other.

  Gut bacteria dominated by Prevotella are associated with healthier outcomes.

• Amber Bryant – Raising Money for Endometriosis Research

  The article, "Amber Bryant - Raising Money for Endometriosis Research", was written by Bill Ormonde and published on Tue 22 April 2025 at 0607.

  Amber, at 28-years-old, can barely get out of bed some days due to her endometriosis, ran to raise the awareness of the disease for Endometriosis Australia — a disease she has struggled with since she was 16, but was only diagnosed with in April 2023.

  As Amber states, her treatment from the medical profession was appalling. "I dreaded going to the doctors because I thought that they felt like I was making it up."

  Unfortunately her efforts are in vain because she is not treating the fundamental cause, that is an excess of sex-hormones, in particular estradiol.

  The good news is that the cause is already known. I have contacted Amber and provided her with references from peer-reviewed medical journals and the remarkable story of Katherine Lawrence who cured her endometriosis in 7 weeks by changing her diet. This did NOT require the purchase of supplementary products. Her story is accessible from the right panel of my website by clicking on the green VIDEOS button.

  I have contacted Endometriosis Australia and Amber on several occasions but have not received a response

• Over-exploitation of Ocean’s Resources

  Of the straddling stocks nearly two-thirds of the stocks (64 per cent) are classified as over-exploited, depleted or recovering, 23 per cent are fully exploited, 12 per cent are moderately exploited.

  Straddling stocks are stocks of fish which migrate between the economic exclusive zone of one or more regions and the high seas. These are highly migratory fish stocks.

  80% per cent of the world’s fish stocks are reported as fully exploited or over-exploited.

  Fishing subsidies greatly distort the fisheries market.

  Global fisheries subsidies were estimated to be US$35 billion. The total revenue from the industry is US$90 billion.

  Harmful subsidies constituted US$20 billion each year consisting of fuel subsidies, management, port and harbour tax relief and equipment modernisation. So US$20 billion each year are subsidising an industry to catch more fish that are over-exploited.
