A vegetarian diet is healthy but...
There
is no doubt that a strictly vegetarian diet is healthier than the
all-too-prevalent sugary, fat-laden, high-starch eating pattern that
characterizes the average American. It takes some careful planning to take
advantage of the benefits of the vegetarian menu and avoid its potential
shortcomings.
Persons
who avoid foods derived from animals boast of the longer lifespan and the
freedom from several chronic diseases that they enjoy and medical science backs
up nearly all of those claims. It’s clear that vegetarians, especially the
vegans, who don’t give in even for eggs and dairy products, have less heart
disease, stroke and high blood pressure. They are less likely to be obese or to
have type 2 diabetes or gallbladder disease, all of which are closely linked.
Claims of lower incidence of cancer, dementia or chronic kidney disease are controversial
although there is no doubt that they are complications of obesity. Lifestyle
factors such as exercise do matter and they tend to complicate any side-by-side
comparison between vegetarians and meat eaters.
Vegetarians
eat foods that fill them up, not fill them out. Vegetables and fruits have lots
of appetite-satisfying fiber and are calorie-sparse. Of course, a vegetarian
diet may also include pastries, candy and soft drinks, a nutritionist’s
nightmare.
When
vegetarians develop health problems on that diet it’s usually because they fail
to include some key nutrients. Iodine is perhaps the most common deficiency
because they avoid fish and may not include enough iodized salt in meal
preparation. Anemia might occur because although there is a moderate amount of
iron in many plant foods it is not as bioavailable
as it is in meat products. Except for the occasional insect that inhabits
fruits and vegetables, there is no vitamin B12, another cause of
anemia. There is less calcium in plant foods but it is absorbed more readily
than from dairy products although some plants have antinutrients that keep calcium from being utilized by the body.
Zinc deficiency may occur for the same reason.
Omega-3
fats are not abundant in plant foods. Strict vegans should take a supplement
that is derived from plant sources such as algae.
Parents
should be aware that vegetarianism may be an eating disorder in disguise. They
should always help a child to plan his or her menu and to monitor them
carefully. Anorexia nervosa and bulemia have severe long-term
consequences.
A
vegetarian diet is healthy. Just do it right.
