Lifestock’s Long Shadow

Dr Henning Steinfeld is an agricultural economist working at the UN as the head of the livestock analysis and policy section. In 2005, he was the lead author of a 400 page UN report Livestock’s Long Shadow.

It stated that the biggest contributor to environmental damage was livestock agriculture. Livestock agriculture includes poultry - both meat and egg production. It is a bigger contributor than transport.

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.

Where do You Get Your Protein

“Where do you get your protein?” (or iron of calcium) is a frequent question for those on a vegan diet. Well, the same place as gorillas, elephants, the grumpy extinct aurochs, brontosaurus and Argentinosaurus- the largest ever land animal weighing more than 15 elephants. From eating plants.

Milks are complex lipid emulsions in water containing protein, fat, lactose, vitamins and minerals, as well as enzymes, hormones and immunoglobulins which provide initial immunity functions.

There is approximately 5,500 species of mammals which initially supply their young with milk. There are vast differences in milk composition among the mammal species. Of all the mammals, humans have the lowest protein content.

Mammals have evolved over millions of years to provide nutrition for their infants in the first stage of life. There are significant difference between species depending upon factors such as rates of growth.

Proteins in human milk provide sufficient of protein to sustain infants for the first six months without any additional food, as well as supplying the means of establishing suitable environment for the growth of healthy intestinal bacteria and providing the proteins involved in the immune system.

Human milk is supplied to babies when the need for protein is at the greatest. Babies double in size during the first 6 months of our lives. The ideal food for a baby is mum’s milk where 5% – 6.5% is protein. This should offer reassurance that as long as we a consuming an adequate diet, we do not need a high protein diet.

How to Survive a Pandemic by Michael Greger

How to Survive a Pandemic by Michael Greger is essential reading for those who wish to understand the history of pandemics and how to minimise their impact on ourselves and our society. The book describes the causes of these diseases and most importantly, how to prevent these events from occurring.

The majority of infectious diseases (and all viral diseases) result from our interaction with animals. This book, with thousands of references, gives detailed descriptions of our greatest diseases from bubonic plague, smallpox, the deadly influenza of 1918 and the deadly viral diseases SARS, MERS and COVID-19.

Zinc, Selenium and the Immune System

Zinc and selenium are important micronutrients required for the immune system to function effectively along with vitamins A, C, E, B6, B12, C, D, E and folic acid and the trace elements iron and copper.

Both insufficient and excessive intakes of zinc and selenium can have negative consequences on the immune status.

For the majority of people, low selenium intake is not a major issue. Whole-grains provide provide a more than adequate supply for vegans.

A serum selenium test shows a short-term status of selenium whilst red blood cell selenium reflects a long-term status.

Before consuming large amounts of selenium in foods or supplements, it is important to know the true status of your selenium.

Lessons from The China Study

Colin Campbell was a nutritional biochemist at Cornell University. In the 1960s, he was involved in nutritional programs in the Philippines to help families provide for their critically undernourished children. Peanuts were one of their preferred sources of protein. It is a legume— great for improving the soil, easy to grow, and is nutritious and tasty.

At the same time, children younger than 10, were dying at alarming rates from liver cancer. Normally liver cancer is an adult disease— and the children dying from the disease were from the most affluent suburbs in Manila. These are the families that could afford the best housing and the best food.

Whilst in the Philippines, he read a paper in an obscure medical journal. Rats were fed aflatoxin— one of the deadliest carcinogens known. One group of rats was given a diet of 20% protein —and they all died of liver cancer. The second group was given a diet of 5% protein— and they all lived. 100% deaths compared to zero deaths. They were all fed aflatoxin— but only those rats that had a high protein diet died.

A 20% diet of wheat protein, gluten, or pea protein did not result in liver cancer deaths whereas casein, which comprises of 80% of the protein found in cow’s milk, and albumin, which is found in egg white, did result in liver cancer deaths. Plant-based diets are often considered to be lysine deficient. However, adding the amino acid lysine to the wheat protein to match the level found in casein also resulted in cancer deaths.

Significantly, peanuts and corn in the Philippines were often contaminated by aflatoxin— and the wealthy ate Western-style diets, one rich in protein.

Dr James Muecke Australian of the Year in 2020

Dr. James Muecke is the Australian of the Year in 2020 which was awarded for his work as an eye- surgeon and his work in preventing blindness.

He is trying to convince Australians to eat more meat, eggs and dairy. Australia is ranked number 2 in meat consumption, just behind United States but in front of Argentina, Uruguay, Brazil and New Zealand.

Dr. Muecke has declared that we need to “Declare war on type 2 diabetes and cut back on sugar” in order to reduce the incidence of blindness.

He believes that it is the introduction of sugary drinks and highly processed foods are the cause of diabetes – not a high-fat, high-protein diet as shown by numerous papers dating back to 1927.

Rural Indian Regional Diets

Despite India's reputation for a healthy, vegetarian cuisine, it is not justified. Only 1.6% of Indians are vegan, 24% are lacto-vegetarian. 3% add eggs to their lacto-vegetarian diet which leaves 72% consuming meat.

The Indian population has the highest prevalence of diabetes worldwide and exhibits high-risk metabolic profiles at younger ages and lower body mass index than their Western counterparts. There are significant regional variations to this observation.

The reasons why Asian populations exhibit diabetes at a lower threshold than western populations are not known.

According to WHO mortality statistics, India is ranked 17 for Low Birth Rate, 37 for Diarrhoeal Diseases, 40 for Tuberculosis, 60 for Malnutrition and 62 for Influenza & Pneumonia out of 183 countries.

Given the current increase in consumption of meat and oils and a decrease in grains, the prevalence of obesity and diabetes is likely to continue.

Are Healthy Diets More Harmful to the Environment

On December 14, 2015 an article titled Vegetarian and “Healthy” Diets Could Be More Harmful to the Environment was published on the Carnegie Mellon University website.

The article quotes Paul Fischbeck, a professor of social and decisions sciences and engineering and public policy at the institute.

He was a co-author of a paper Energy use, blue water footprint, and greenhouse gas emissions for current food consumption patterns and dietary recommendations in the US.

Professor Fischbeck is quoted in the website article, stating:

“Eating lettuce is over three times worse in greenhouse gas emissions than eating bacon. Lots of common vegetables require more resources per calorie than you would think. Eggplant, celery and cucumbers look particularly bad when compared to pork or chicken.”
