Before now, vegetarianism was usually
found among those who had eating disorders, especially in adolescents.
Not so again, as people adopt vegetarian diets for various reasons,
ranging from religious to medical.
Nutritionists say being a vegetarian
means your diet is restricted to foods of vegetable origin, excluding
all meats of animal origin. Experts note that, generally, most
vegetarians eat eggs and dairy products (milk products).
In extreme cases, there are those who
don’t eat any animal protein at all – not even eggs, dairy, or honey.
Such people are known as vegans. Our focus, however, is on vegetarians;
and the idea is to help you make informed choices about your dietary
needs.

Benefits of vegetarian diet
A scientist at the Institute of
Nutritional Sciences, University of Giessen, Germany, Mr. Claus
Leitzmann, in a study reveals that there are many accruable health
benefits one can derive from eating wholly vegetarian diet.
The Leitzmann research notes that “A
growing body of scientific evidence indicates that wholesome vegetarian
diets offer distinct advantages, compared to diets containing meat and
other foods of animal origin.”
He goes further to say that with a
vegetarian diet, you take low quantity of saturated fat, cholesterol and
animal protein; while it also exposes you to higher intakes of complex
carbohydrates, dietary fibre, magnesium, folic acid, vitamins C and E,
carotenoids and other phytochemicals.
“All these impact positively on health
on the long run,” says the Nutrition Specialist at MART-Life Detox
Clinic, Lagos, Mrs. Idowu Ashiru.
Ashiru explains that well-balanced
vegetarian diets are appropriate for all age groups, including children,
adolescents, pregnant and lactating women, the elderly and even
athletes.
She says, “As part of the modern Mayr
medicine, for instance, in most cases, vegetarian diets are beneficial
in the prevention and treatment of certain diseases, such as
cardiovascular disease, hypertension, diabetes, cancer, osteoporosis,
renal disease and dementia; as well as diverticular disease, gallstones
and rheumatoid arthritis.”
She discloses that the antioxidant
effects of eating more vegetables and fruit are commendable, as they
help the body to combat harmful naturally-occurring chemicals in the
body.
A recent work by researchers at the Loma
Linda University in California, and published in the JAMA Internal
Medicine, even claims that vegetarian diet can confer longevity.
Study leader, Dr. Michael Orlich,
enthuses that in a study of more than 70,000 people, researchers found a
cut in death rates for people eating vegetarian diets, compared with
non-vegetarians.
Orlich says, “Over a six-year period,
vegetarians were 12 per cent less likely to die from any cause, compared
with non-vegetarians.”
The scientists also note that the
benefits come from lower blood pressure and improved cholesterol levels
in people eating low-fat diets based on vegetables, whole grains and
fruit; and partly through avoidance of red meat.
Indeed, another scientific study of
45,000 British subjects earlier in the year found that vegetarians have
healthier hearts than people who eat meat or fish.
Avoiding pitfall
Despite the medical benefits of
vegetarian diet, though, experts say poor meal planning can lead to
deficiency in several nutrients, including protein, iron, zinc, calcium,
vitamin B12 and A, omega-3 fatty acids and iodine.
Scientists at Brown University warn that
even a vegetarian diet can be high in fat if it includes excessive
amounts of fatty snack foods, fried foods, whole milk dairy products,
and eggs.
“Therefore, a vegetarian diet, like any
healthy diet, must be well planned in order to help prevent and treat
certain diseases,” the scientists counsel.
Nutritional needs
Dieticians fear that it is possible for
vegetarians to miss out on what they call “nutrients of concern,” hence
the need for them to eat foods that contain the following nutritional
values:
Vitamin D. Scientists say vegetarians
may not eat enough D vitamin foods except they are aware that they could
get the recommended quantity through dairy products (milk) and eggs,
breakfast cereals, fruit juices and margarine.
Vitamin B-12. Nutritionists say since
Vitamin B-12 is found almost exclusively in animal-based foods, it is a
nutrient of potential concern for those following a vegetarian diet.
They warn that anyone who significantly limits intake of animal-based
foods requires vitamin B-12-fortified foods or supplements, in order to
prevent the consequences of B-12 deficiency.
To get enough of this vitamin,
nutritionists advise vegetarians to eat mushrooms, eggs, cheese, yogurt
and fortified foods, like cereals.
Calcium. The online portal, care2.com,
says you can get calcium from all sorts of plant-based sources, and that
they’re often better for your bones than dairy products. “Unlike milk,
plant-based calcium sources contain vitamins C and K and the minerals
potassium and magnesium, which are all important for bone health,” the
portal claims.
Calcium-rich vegetarian foods include fortified orange juice, soya-based foods, broccoli, oranges, dark green vegetables, etc.
Meat-free protein
Studies have shown that vegetarians can
easily meet their protein requirements by simply eating a variety of
vegetables, especially leafy greens. Plant-based protein sources include
beans (cooked or made into soup), nuts and seeds (though high in fat
and calorie, they’re also an excellent protein source and full of
vitamins and minerals).
Other sources of meat-free protein are
peas, raw milk, cheese and yogurt, and whole grain, which is also full
of healthy fibre. When combined with nuts or beans, it provides a
protein-heavy dish every time.
Non-animal iron sources
Ordinarily, eating red meat and organ
meat is the most efficient way to get iron; but for vegetarians,
obviously, that’s not going to happen. Here are some plant-based foods
with some of the highest iron levels: cooked soya beans, tofu
(cheese-like food from soya), tempeh (fermented soya bean cake),
lentils, home-made tomato paste, white beans, cooked spinach, dark
chocolates, etc.
Nutritionists advise eating iron-rich
foods along with foods that contain vitamin C, which helps the body to
absorb the iron. Again, they say, since calcium hinders the absorption
of iron, avoid high-calcium foods for a half hour before or after eating
iron-rich foods.
Potassium
Experts note that potassium is essential
for normal body functioning, for the prevention of excess fluid
retention and for the metabolism of carbohydrate and protein. “Too much
potassium or less potassium is harmful to the body,” scientists say. For
a vegetarian, get your potassium need from raw or cooked plantain,
guava, avocado, banana, white beans, soya beans, carrot juice, melon,
fresh orange, baked potato, sweet potato, yam, cooked spinach, tomato
juice, pineapple juice, tangerine, mashed potatoes with margarine,
yoghurt and skimmed milk.
Essential fatty acids
Experts say the body needs quality fats
to help it absorb the ‘fat soluble’ vitamins A, D, E and K, to regulate
cholesterol, provide energy, and to maintain heart health, among others.
They recommend using extra virgin olive oil, raw butter, and coconut
oil.
Supplements
Experts advise that you consult a physician before taking food supplements.
