Animal proteins versus plant proteins


by Tammy Fry Kelly, Marketing Director – Fry’s Family Foods

Most people really believe that the only way you can get protein is from animals – think meat, eggs, and dairy!  And the age-old myth that Vegans cannot be as strong and as healthy as their meat-eating counterparts is exactly that – an age-old myth!

Let’s talk more about plant proteins – where are they found, and why are they better for you than animal protein. Big statement, but I am sticking to it! In order to understand protein, you need to know some of the basics.

Proteins are made up of amino acids.  There are said to be 9 essential amino acids, or in simple terms, amino acids that our body needs but cannot “manufacture” itself.  We need to get these from the food we eat.  When we consume protein, our body breaks down the protein into its components and then “manufactures” the right strands of protein for what our body requires at that particular time. This is not a difficult job for our bodies to do – it is what we are designed to do.

It is critical to note that plant proteins contain all of these 9 essential amino acids, and in levels often higher than meat.  In fact, most plants have protein levels equal to that of meat.  About 15% of the calorie level of plants is protein!  (And I bet this is news to you!)

But here’s the catch.  Animal Protein is closer in its make-up to human protein, hence the preconceived idea that it is a better source.  However, this does not mean that it is of better quality or good for long-term health.

Animal Protein has in fact been shown many times over to be detrimental to human health.

There have been many epidemiological studies and clinical research conducted, most notably, The China Study, that have proved this.

A collaboration between the Chinese Academy of Preventive Medicine, Cornell University, Oxford University, resulted in the most comprehensive study of diet, lifestyle and disease that has ever been conducted in the history of medical research. In the study, researchers surveyed a wide range of diseases, diet, and lifestyle factors across rural China and Taiwan, and produced more than 8,000 statistically significant associations between various dietary factors and disease – this was published as the China Study.

Some of the findings were:
Animal Protein in the diet (all sources – incl milk/egg or meat) is linked to:

Higher Cholesterol levels

Increased heart disease

Increase Type 1 Diabetes

Increased cell division – faster growth of cancer tumours, Alzheimer’s, and other diseases.

Increased osteoporosis 

I would like to share this graph which comes from T Colin Campbell Centre of Nutrition Studies:

The same results were not prevalent with plant protein!  In fact plant proteins were shown to have the opposite effect:

Lower cholesterol levels
Reversal of heart disease
Lower rates of both types of Diabetes
Lower cancer growth (even reversed cancer)
Lower risk of osteoporosis

What was even more incredible is that even when people had a genetic predisposition to one or other of these diseases, a plant based diet prevented the actualisation of the disease.

So, no.  Plant proteins and animal proteins are not equal.  Plant proteins are better for your health than animal protein.
