Vegan Diets For Small Children: Safe Or Not?

A vegan diet is a plant-based diet that excludes meat, fish, eggs, honey, and dairy products. It can be challenging to meet a child's nutritional needs with a vegan diet, but it is possible with careful planning.

Vegan diets tend to be less energy-dense, so children may need to eat larger quantities to meet their energy needs. It is important to ensure that children on a vegan diet are getting enough calories, protein, vitamins, and minerals.

Some key nutrients to pay attention to include calcium, vitamin D, vitamin B12, iron, and omega-3 fatty acids. These nutrients are typically found in animal-based foods, so it is important to include plant-based sources of these nutrients in a vegan diet or consider supplementation.

Breast milk is recommended as the best source of nutrition for infants in the first six months of life. After six months, parents can introduce plant-based milk alternatives, but it is important to choose those that are fortified with calcium and vitamin D.

When introducing solid foods, parents should offer a variety of nutrient-dense foods such as vegetables, pulses, nuts, seeds, and fruits. It is important to ensure that children on a vegan diet are meeting their calorie and nutrient needs and monitor their growth and development.

Some organizations support vegan diets for children, while others express caution or recommend against them. It is important for parents to consult with a healthcare professional before making any significant dietary changes for their children.

Calcium and vitamin D are essential for bone health

Vitamin D is crucial for the absorption of calcium by the body. Without vitamin D, both calcium and phosphorus absorption are reduced. The body only absorbs around 10-15% of calcium without vitamin D. The absorption of calcium takes place in the intestinal tract, particularly in the lower part known as the ileum, and vitamin D enhances calcium's entry into the digestive tract.

Vitamin D can be obtained through exposure to sunlight, particularly the sun's UVB rays. When UVB radiation reaches the skin, it is converted to previtamin D, and then to vitamin D3. Spending around 10 to 30 minutes in the sun three times a week is enough for most people, though those with darker skin may need more sun exposure.

Calcium can be obtained through a vegan diet, though vegans have been shown to have a lower intake of calcium and vitamin D compared to non-vegans. Calcium-fortified plant milk contains the same amount of calcium as cow's milk, and calcium-fortified yoghurt alternatives, calcium-set tofu, and soya and linseed bread are also rich sources. Green leafy vegetables such as broccoli, cabbage, and okra are also good sources of calcium, though spinach is not as it has very poor absorbability.

It is important to ensure that children, particularly those following a vegan diet, achieve their daily calcium requirement. Inadequate dietary calcium intake during periods of growth can cause poor bone health later in life. For example, osteoporosis, a disease that can result from increased bone weakness, can be prevented by eating a diet with adequate amounts of calcium throughout childhood.

Iron is needed to produce healthy red blood cells

There are two types of dietary iron: heme and non-heme. Heme iron is found in animal products and is more easily absorbed by the body. Non-heme iron is found in plant-based foods and is not as easily absorbed.

To ensure adequate iron intake on a vegan diet, it is important to include a variety of iron-rich plant-based foods in the diet. Good sources of non-heme iron include:

• Whole wheat breads, cereals, pastas, quinoa, and oatmeal
• Cooked spinach, asparagus, and green beans
• Beans, legumes, soybeans, tofu, and lentils
• Dried apricots, raisins, and dates

Additionally, pairing iron-rich foods with vitamin C-rich foods can enhance iron absorption. Good sources of vitamin C include:

• Citrus fruits and citrus juice
• Red or green bell peppers
• Kiwi, strawberries, tomatoes, cantaloupe, and papaya

Vitamin B12 is crucial for nerve and blood cell health

Vitamin B12 is essential for nerve and blood cell health. It is a crucial nutrient that helps the body maintain healthy nerve cells and blood cells, as well as produce DNA, the genetic material found in all cells. Vitamin B12 is naturally found in animal products such as meat, dairy, and eggs, and a deficiency can lead to physical, neurological, and psychological problems.

Vitamin B12 is particularly important for nerve health, as it helps to keep nerve cells healthy. A deficiency can cause neurological symptoms such as numbness or tingling in the hands and feet, difficulty walking, and cognitive difficulties. In severe cases, it can lead to deep depression, paranoia, delusions, memory loss, and other psychological issues.

For children following a vegan diet, it is important to ensure adequate intake of vitamin B12 to support nerve and blood cell health. Fortified breakfast cereals, some low-salt yeast extracts, and fortified plant-based milk and soy products are good sources of vitamin B12 for vegans. However, supplementation may be necessary to ensure adequate intake.

Overall, while a vegan diet can be healthy for children, it requires careful planning and appropriate supplementation to ensure adequate intake of essential nutrients like vitamin B12.

Omega-3 fatty acids are needed for a healthy heart

Omega-3 fatty acids are "healthy fats" that support heart health. They are a type of polyunsaturated fat, which is considered a "good" or "healthy" fat because it supports heart health when consumed in moderation. Omega-3 fatty acids are essential nutrients, meaning that our bodies cannot produce them, so we must obtain them from our diet.

There are three main types of omega-3 fatty acids: eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (ALA). EPA and DHA are found mainly in seafood, while ALA is found in plants.

Benefits of Omega-3 Fatty Acids for Heart Health

Omega-3 fatty acids have been shown to provide several benefits for cardiovascular health:

• Lowering triglyceride levels: High triglyceride levels in the blood can increase the risk of atherosclerosis, heart disease, and stroke.
• Raising HDL ("good") cholesterol: Higher levels of HDL cholesterol are associated with a reduced risk of heart disease.
• Lowering blood pressure: High blood pressure is a risk factor for cardiovascular disease.
• Reducing the risk of cardiovascular events: Omega-3 fatty acids have been linked to a reduced risk of heart attack, stroke, and death from coronary heart disease.

Sources of Omega-3 Fatty Acids

The best dietary source of omega-3 fatty acids is fish, particularly fatty fish such as salmon and mackerel. However, for those who follow a vegan diet or are allergic to seafood, there are plant-based sources of omega-3 fatty acids, including:

• Flaxseed
• Chia seeds
• Walnuts
• Soybean oil
• Canola oil

It is important to note that the body's ability to convert ALA from plant sources into EPA and DHA is limited, so dietary sources of EPA and DHA are still essential. For this reason, some vegans choose to supplement their diet with omega-3 fatty acid supplements derived from microalgae.

Recommendations for Omega-3 Fatty Acid Intake

The American Heart Association recommends that people without a history of heart disease consume at least two servings of fish per week. For those with heart disease or high triglyceride levels, higher intake of omega-3 fatty acids may be beneficial, but it is important to consult a healthcare provider for personalized advice.

While omega-3 fatty acid supplements are available, it is generally recommended to obtain these nutrients from food sources whenever possible. If considering supplements, it is important to speak to a healthcare provider first, as they may interfere with certain medications or have side effects.

Omega-3 Fatty Acids for Children

For children, omega-3 fatty acids are important for brain development and heart health. However, children following a vegan diet may be at risk of not obtaining adequate amounts of these essential fats, as plant foods are not the richest source. In this case, supplementation with omega-3 fatty acids derived from microalgae may be recommended.

Breast milk is a good source of omega-3 fatty acids for infants, and infant formula is typically fortified with these essential fats. For older children, including a variety of plant-based sources of omega-3 fatty acids in the diet, such as chia seeds, flaxseeds, and walnuts, can help ensure adequate intake.

Omega-3 fatty acids play a crucial role in maintaining a healthy heart. They help to lower triglyceride levels, raise HDL cholesterol, and reduce the risk of cardiovascular events. While fish is the best source of omega-3 fatty acids, plant-based sources are also available, making it possible for those following a vegan diet to obtain adequate amounts. However, supplementation may be necessary in some cases, especially for children, to ensure optimal heart health.

Iodine is needed for thyroid health

Iodine is a vital nutrient for the body and is essential for thyroid function. The thyroid is a butterfly-shaped organ in the neck that plays a major role in many bodily processes, especially in maintaining body temperature and balancing metabolism. The thyroid gland produces two main hormones, T3 (triiodothyronine) and T4 (thyroxine), and dysfunction of these hormones can affect overall health.

Iodine deficiency and thyroid disorders

Iodine deficiency is the most common cause of thyroid disorders globally. Iodine is essential for the production of thyroid hormones, and since animal products tend to be rich in iodine, vegans can be at a higher risk of developing iodine deficiency. However, it is important to note that too much iodine can also be harmful.

Sources of iodine in a vegan diet

Plant-based dietary sources of iodine include fortified plant-based milk, iodised salt, and seaweed. Nori sheets, for example, contain approximately 35-40 mcg of iodine per sheet. If a vegan diet does not include these sources of iodine, a supplement of 150 mcg of iodine per day is recommended.

Iodine and thyroid medication

It is important to monitor iodine intake, especially for those with hypothyroidism or Hashimoto's thyroiditis, as soy products, which are often used as a protein replacement for meat, may adversely affect thyroid function by interfering with the absorption of thyroid medication.

Iodine and Hashimoto's thyroiditis

Hashimoto's thyroiditis is an autoimmune condition and the most common type of hypothyroidism. Research suggests that too much iodine may trigger Hashimoto's disease. Therefore, those with Hashimoto's should aim for 150-400 mcg of iodine per day and consider taking thyroid supplements that do not contain iodine.

Iodine and children

Iodine is a critical nutrient for children as well. A reliable source of iodine is important for children following a vegan diet, and a supplement is typically recommended. However, some plant-based milks may contribute to iodine intake if they have been fortified.
