Is A Vegetarian Diet Safe For My Child?

If you are vegetarian parent, you have probably considered putting your child on a vegetarian diet. Not only would it save time and make meal-planning easier, but for dietary and ethical reasons, you believe it is a better choice for your child.

Conversely, you might not be a vegetarian yourself, but have a child who is going through a vegetarian "phase," where she rejects meat, but doesn’t consume enough healthy foods to compensate for the nutritional gap.

Whatever the case is, you may have wondered whether or not a vegetarian diet is sustainable, healthy choice for your child. You may have heard that putting your child on a vegetarian diet could potentially stunt her growth.

These concerns probably prevented you from putting your child on a vegetarian diet up to this point.

And all of these concerns are legitimate. In fact, if a vegetarian diet is poorly planned, it can cause serious short and long term health problems, especially for children, who are growing and developing--and who do not yet have sufficient stores of vitamins.

If you aren’t well-prepared to put your child on a vegetarian diet, you definitely shouldn’t. However, if you have done your nutritional research and you are familiar with the nutrients vegetarians commonly lack, then you know that these problems can easily be overcome with some meal planning.

You also know that putting your child on a healthful vegetarian diet can greatly improve her health in both the short and long term. It can also reduce her exposure to animal products that contain hormones and preservatives, which have been linked to developmental problems and cancer.

If you haven't researched vegetarian diets thoroughly, but you are anxious to start your child on one now, you should start by ensuring that you plan meals to boost amounts of the following nutrients (that most vegetarians lack):
  1. Protein. Make sure your child is consuming enough protein by adding additional sources, such as wheat, soybeans, isolated soy protein, and nuts.
  2. Calcium. Ensure your child is consuming enough calcium by adding calcium-fortified processed foods and leafy green vegetables to his diet.
  3. Iron. Add more iron to your child’s diet by increasing servings of soybeans, pinto beans, tofu, and cereals.
  4. Zinc. Enhance your child’s zinc intake by increasing his servings of almonds, peanut butter, and mushrooms.
If you concentrate on compensating for all of these common nutritional deficiencies, you absolutely can put your child on a vegetarian diet without any negative health consequences.

Just ignore the mythology surrounding vegetarian diets and instead focus on research and meal-planning.

The Top Five Nutrients Vegetarians Lack

Both vegetarian and non-vegetarian diets have advantages. Vegetarian diets tend to be rich in antioxidants, certain vitamins, and healthy fats. Non-vegetarian diets, by contrast, tend to contain more protein, iron, zinc, calcium, and vitamin B-12.

If you already decided to adopt a vegetarian diet, it is essential you learn how to increase your intake and absorption of these nutrients to avoid short-term and long-term health complications.

In the next few paragraphs, I will explain how you can regularly assimilate larger portions of these nutrients into your regular diet:

1. Protein. Different types of protein are made up of different permutations of amino acid chains. In order to create a "complete protein" or a protein that can be assimilated into the human body as tissue, you must consume foods that contain complementary chains of amino acids.
Wheat, nuts, and beans are three types of vegan-friendly incomplete proteins; however, wheat is hard to digest and up to 50% of its protein is lost during the process.
Isolated soy protein, which you can get from a number of sources (including soy milk), can be digested efficiently-enough to match the animal protein yields.

2. Iron. Plant sources contain a significant amount of iron, but in nonheme form, which is more sensitive to inhibitors than iron that comes from animal products. You should do two things to increase your blood-iron levels:
a) consume more plant iron; and
b) avoid absorption inhibitors, such as tea, coffee, and fiber.

3. Zinc. Whereas non-vegetarian diets seem to enhance the absorption of zinc; vegetarian and vegan diets do the exact opposite--they inhibit it.

Nutritionists suggest that you can overcome this by consuming more foods that contain zinc, such as soybeans, cashews, and sunflower seeds while reducing your intake of inhibitors by washing vegetables and grains.

4. Calcium. While vegetarians can easily consume an adequate amount of calcium without any dietary additions, it is important that vegetarians avoid consuming certain foods that are high in oxalates, which inhibit calcium absorption.

Dietitians suggest that vegetarians do not consume spinach, beet greens, and swiss chard as the calcium component of a meal plan. While they are rich in calcium, they also contain high amounts of oxalates.

Rather than consuming those foods for calcium, vegetarians should consider other options, such as soy yogurt, tofu, beans, almonds, and calcium-fortified foods.

5. Vitamin B-12. Many vegetarians lack vitamin B-12 simply because it does not exist naturally in any non-animal forms. Vegetarians should seek out vitamin B-12 fortified foods, such as certain soy milks and cereals to supplement what they lack.

As I outlined, there are a number of nutrients vegetarians can lack of they do not research and plan. This is not meant to discourage people from becoming vegetarians, but instead to encourage them to spend time planning a health approach to their vegetarian diet before starting it.

When planned adequately, a vegetarian diet can not only make up for what it lacks from animal products, but it can far exceed the healthfulness of most non-vegetarian diets.

Important Non-Meat Sources Of Protein For Vegetarians

Although most vegetarians consume a considerable amount of protein, they often do not absorb as much as they would on a nonvegetarian diet. This is because plant proteins are considerably less digestible than animal proteins, which contain amino acid chains that are closer or identical to human amino acid chains.

Consuming animal proteins might yield close to a 1:1 absorption ratio, while consuming plant proteins, such as wheat, might only yield 50% of the amino acids needed to build a "complete protein" or a protein that can readily be assimilated into the human body.

In order for vegetarians to absorb a healthy amount of protein, they must consume a variety of plant proteins to form complete amino chains. By eating vegetables, legumes, seeds, nuts, fruits, and whole grains, vegetarians can increase the amount of complete proteins they create by combining a number of varieties of amino acid chains.

Vegetarians must also consume more foods that contain proteins because plant proteins are generally harder to digest. While a nutritional label may suggest that pasta has 5 grams of protein per serving; you may only be able to digest 2-3 grams of that protein, which means you must complement the pasta with other sources of protein.

In addition to natural sources of protein, vegetarians should also seek foods that are "protein-fortified"-- or artificially-infused with protein.

For example, many supermarkets offer a variety "protein-fortified" pasta and bread. I have seen pasta that contains as much as 12 grams of protein per serving.

Soy milk is also a good source of protein for vegetarians. Studies on isolated soy protein show that it can be absorbed nearly as well as animal proteins, yielding close to a 1:1 protein absorption ratio.

For non-vegan vegetarians, yogurt, milk, and eggs (which contain complete proteins) are all excellent sources of protein.

As a vegetarian you have a number of options to boost your protein intake - and you should consider taking advantage of all of them. You should diversify your food selections, drink more soy products, and eat "protein-fortified" breads and pasta.
