Diabetes,
a common disease which affect
more than 20 million people in the United
States—7.0 percent of the population. For
diabetics the choice of food really can be a matter
of life and death. Diet is one of the most important ways of controlling
diabetes beside medications and exercises. This article is going to discuss in
depth the relationship of vegetarian diet and diabetes.
Introduction to Vegetarian Diet
A vegetarian is a person who
avoid meat and/or animal products.
Vegetarian diet includes
only foods from plants: like
fruits, vegetables, plenty of leafy greens, whole grain products, nuts, seeds,
and legumes
(dried beans
and peas).
There are several categories of vegetarians:
Part-Vegetarian or Semi-Vegetarian
Semi-vegetarians do not eat red or white meat
(beef, pork, venison, etc) but include chicken and fish with plant foods,
dairy products, and eggs.
The only animals that semi-vegetarians eat are fowl and fish, although they
usually eat by-products of red meat, like fats, oils, gelatin etc. and wear
clothes from animals.
Ovo-Lacto Vegetarians
Do not eat meat or flesh of any kind, but do
eat eggs and dairy products. Sometimes ovo-lacto vegetarians eat meat
by-products (e.g. fats, bonemeal, gelatin) and use animal-derived products
(leather etc.).
- The Ovo vegetarians eat eggs but not dairy
products.
- The lacto vegetarian diet includes plant foods
plus cheese and other dairy products but not eggs.
Vegans
Vegan or
total vegetarian
are strictly vegetarians. They eat only plant foods:
includes fruits, vegetables, plenty of leafy greens, whole grain products, nuts,
seeds, and legumes
(dried beans
and peas). Vegans, in addition to
being vegetarian, do not use other animal products and by-products such as eggs,
dairy products, honey, leather, fur, silk, wool, cosmetics, and soaps derived
from animal products.
Despite such dietary restrictions, a balanced vegan diet is perfectly healthy,
although too inconvenient for many vegetarians.
Macrobiotic Vegetarians
A macrobiotic vegetarian diet excludes all
meat, poultry, dairy produce and eggs, but at initial levels may include fish. A
macrobiotic vegetarian aims to maintain a balance between foods seen as ying
(positive) or yang (negative). The macrobiotic diet progresses through ten
levels, and becomes more and more restrictive. Not all levels are vegetarian,
though each level gradually eliminates animal products. The highest levels
eliminate fruit and vegetables, eventually reaching the level of a brown rice
diet.
A macrobiotic vegetarian diet is not recommended
from a nutritional viewpoint.
Studies show that vegetarian diet which
emphasis on low fat, high carbohydrate and high
fibre foods has
a
beneficial effect on carbohydrate metabolism, lowering
blood sugar levels. Therefore can
substantially lower risk of type II diabetes and other health problems like
obesity, coronary heart disease, high blood pressure
and some forms of cancer than
non-vegetarians.
A
carefully planned healthful and nutritionally sound
vegetarian
diet should include
essential nutrients,
Protein - Almost all foods except for alcohol, sugar, and fats
are good sources of protein.
Proteins from plant alone can provide sufficient of the essential and
non-essential amino acids, as long as sources of dietary protein are varied and
caloric intake is high enough to meet energy needs. Whole grains, legumes,
vegetables, seeds and nuts all contain both essential and non-essential amino
acids. Soy protein has been shown to be equal to proteins of animal origin. It
can be your sole protein source if you choose.
Iron - Dried beans, spinach, enriched products, brewer's yeast and
dried fruits are all good plant sources of iron.
Vitamin B-12 (cyanocobalamin) - This vitamin is plentiful in meat
poultry, fish, eggs and daily products- that is foods from animal sources.
Vegans can get B-12 from soy products, such as soy drinks, that are fortified
with this vitamin.
Vitamin D - Vitamin D is produced by exposure to sunshire. Provided the
ultraviolet light is not affected by smog, dust, or cloud, about 15 minutes a
day or 1 - 2 hours a week will ensure adequate amounts are produced. you can
also get it from dairy foods, like full-cream milk, cheese and cream.
Calcium - Studies show that vegetarians absorb and retain more calcium
from foods than nonvegetarians do. Calcium
Vegetabis found in dark green vegetables
such as spinach, kale and broccoli, and some legumes and soybean products, are
good sources of calcium from plants. Many dairy foods, especially milk and
yoghurt, are also excellent sources of calcium. The recommended intake
for calcium for adults 19 through 50 years is 1000 milligrams/day.
Zinc
- Zinc is needed for growth and development. Good plant sources include
grains, nuts and legumes. Shellfish are an excellent source of zinc. Take care
to select supplements containing no more than 15-18 mg zinc. Supplements
containing 50 mg or more may lower HDL ("good") cholesterol in some people.
Fat - Vegan diets are free of cholesterol and
are generally low in fat. High-fat foods, which should be used sparingly,
include oils, margarine, nuts, nut butters, seed butters, avocado, and coconut.
Recommended Meal Plan for Vegetarian
-
Minimum intake of sweets and fatty foods to a
minimum as these foods are low in nutrients and high in calories.
-
Choose whole or unrefined grain products when
possible, or use fortified or enriched cereal products.
-
Variety intake of fruits and vegetables, including
foods that are good sources of vitamins A and C.
-
If you use milk or dairy products, choose
fat-free/nonfat and low-fat varieties.
-
Eggs are high in cholesterol (213 mg per yolk), so
monitor your use of them. Limit your cholesterol intake to no more than 300
mg per day.
Note : A
vegetarian diet can be unhealthy if it contains too many calories and not enough
important nutrients. Ensuring adequate amounts of essential nutrients in
vegetarian diet is vital in the case of diabetes.
