Nutritional Pros and Cons
of Meat-based and Vegetarian Diets
Most individuals who have switched to a vegetarian lifestyle73 at some point in their lives (who were not born
into it), have done so following some form of perceived enlightenment, or after the realization that consuming
animal products is either anti-religious, anti-earth (to save the planet), against animal rights, or that it is
simply unhealthy. I have been testing and treating many vegetarian patients for more than three decades, so
I am presenting arguments for and against the consumption of animal-based products strictly from a health-
point of view.
Contrary to vegan-based reviews or commentaries, people following a strict vegetarian diet are not healthier
than their omnivorous counterparts. In fact, based on clinical records, they suffer from just as many or more
medical problems as compared to non-vegetarian individuals, who include meat or eggs in their diet.
There is absolutely no question that the average individual does best health-wise by consuming a mixed diet
that is as fresh, and hopefully as unprocessed as possible. Beyond that, an individual assessment is required
to provide the necessary information to help make a decision of whether one's diet should be adjusted with
greater emphasis toward
• specific food groups,
• a change in the percentage of the carb, protein, or fat content of a meal, or
• toward a more vegetarian or non-vegetaria diet - to achieve a more optimal approach to health.
Mineral ratios (potassium / sodium, or calcium / phosphorus...) of common foods or beverages consumed
also deserve attention as they can have a favorable or unfavorable effect on someone's health problems.
Kidney and liver chemistry are the chief resources to base the decision on of whether a patient would benefit
more from an omnivorous, or vegetarian lifestyle. Individuals who predominately exhibit lower levels of iron,
protein, phosphorus, sodium, and manganese, and higher levels of potassium and zinc are better candidates
for diets with a greater emphasis on meat, while those with a tendency for higher levels of the above (iron,
protein, phosphorus, sodium, and manganese), and lower levels of zinc and potassium, are better candidates
to adopt vegetarianism, and they should reduce, or avoid animal-based food sources accordingly.
Suffering from liver diseases, such as hemochromatosis (iron overload), is a prime example where avoiding red
meat and/or adopting a more vegetarian-based lifestyle would have a more favorable effect on that condition,
while certain other medical situations (e.g. kidney disease), would equally benefit from vegetarian-based diets,
but even then, oxalic acid-rich vegetables, which worsen kidney functions, would have to be avoided, while
kidney failure would prohibit the consumption of potassium-rich diets altogether.
At the same time, individuals already exhibiting very high levels of cellular potassium or zinc, and as such are
at a much greater risk to develop genitourinary conditions, including ovarian or testicular cancer, also have to
avoid strict vegan-types of diets that tend to provide much higher levels of both of these elements.
One of the misconceptions perpetuated by some sources is that eating meat causes cardiovascular disease,
while vegetarian diets prevent it. We all know that the body cannot exist without cholesterol, and that dietary
cholesterol has little, or no impact on serum cholesterol, so that leaves oxidation of fats and simple sugars
(once converted in the liver) as contributing factors with atherosclerosis. However, this effect is not meat,
nor vegan / vegetarian-specific, and neither are antioxidants, which can be animal and/or vegetarian-based.
I have patients, who as a result of following a strict vegan lifestyle enjoy optimal health, and I have patients
who, as a result of eating mostly meat, enjoy optimal health as well. The secret is not always the type of diet
itself, but frequently the avoidance of what is generally conceived as being junk food, which can be part of
a vegetarian and omnivorous lifestyle. At the same time, diets should be based on genetic requirements,
to complement one's individual chemical make-up, but should not be based on dogmas or agendas. ¤
There are no vegetarian sources of Vitamin B12, which is why herbivores (e.g. rabbits) meet their Vit B12
requirements by eating plants that are infested with insects, or by eating their own feces, while in ruminants
(sheep, cows), the microbes fermenting and digesting plant material in the rumen (the first stomach)
incorporate cobalt into Vitamin B12, which is subsequently absorbed and utilized. (see also "Nickel & Cobalt").
Vit B12 liver reserves in adults may last for several years before becoming depleted as a result of switching
to a strict vegan or vegetarian diet, however Vitamin B12 deficiency in vegetarian children is much more
serious since symptoms do not always become obvious or acute until some damage has resulted. While it is
recommended to supplement extra amounts of Vitamin B12 with vegetarian adults, it is mandatory with vegan
or vegetarian children!
Because of improved sanitation, this is much more important in Western societies, since in lesser developed
parts of the world, insect or feces-contaminated fruits or vegetables have generally been sources of Vit B12
for those growing up in a predominantly vegetarian environment or culture.
It may also be advisable to supplement a very small amount (DRI / RDA) of the active form of Vitamin B6
(pyridoxal-5-phosphate), since vegetarian sources of Vit B6 only supply the inactive form (pyridoxine), which
will have to be converted to the active form by the liver, however the efficiency of the liver to do so may be
compromised with certain types of liver diseases. Ideally, when supplementing Vitamin B6 as pyridoxine, a
brand should be purchased that supplies a small percentage of Vitamin B6 as pyridoxal-5-phosphate (P5P)
as well.
Both, Vitamin B12 and Vitamin B6 (along with folic acid and others) are also able to lower artery-damaging
homocysteine levels, which tend to be on the high side with many vegetarians. Research74 has shown that
only 5% of omnivores, but 28% of vegetarians and 53% of vegans presented with hyperhomocysteinemia,
so the addition of these vitamins would have a favorably affect on a vegetarian's cardiovascular system also.
The decision to supplement additional iron (particularly with vegetarian women), or protein, may have to be
made based on actual lab tests, whereby low protein and/or iron frequently - but not always, may suggest low
sodium levels also. Using normal amounts of table salt will on average resolve that situation, however in low
aldosterone types, where using salt alone will not bring up sodium levels, supplementing choline bitartrate or
licorice may be a consideration.
When iron levels test below normal, then manganese supplementation is frequently indicated as well, being
the associated mineral of iron, which may help with low estrogenic-types of PMS, or hypoglycemic / low blood
sugar-types of symptoms. This tends to develop when high potassium intake - being more prevalent with
vegetarianism - gradually depletes manganese levels in the body.
Why do vegetarian diets worsen cholesterol or triglyceride profiles in some people?
A high potassium / manganese ratio is generally responsible for total cholesterol levels to rise following the
switch to a vegetarian lifestyle, while lower sodium can be the cause of LDL fractions to go up. Likewise, a
rise in zinc is common when switching to vegetarianism, being partly supported by a decrease in iron (high
zinc / low iron ratio), which may result in raised total triglyceride levels.
At the same time, lower protein and/or phosphates would be the cause for VLDL triglyceride fractions to go
up - which of course can also happen following an increase in the consumption of simple carbohydrates
(sugar, honey, dates figs, sweet fruits or fruit juices), or a greater intake or retention of calcium.
