Healthy Vegetarianism


A philosophy of eating, like vegetarianism, has to be understood in the context of the motivation for doing it. The reason for adopting a vegetarian or vegan way of life may be: ethical, animal welfare, environmental, health, economic, world hunger issues or religious beliefs.

In the broadest sense, a vegetarian is a person who does not eat meat, fowl or fish or products containing these foods. However within this broad term, there are a number of sub-groups of vegetarianism. Some of these include:

Demi-vegetarian - the only restriction is red meat

Partial vegetarian - eat fish and poultry

Ovo-lacto-vegetarian - eat animal products such as egg and dairy

Lacto-vegetarian - only dairy products are eaten

Vegans - eat no animal products at all. These are the most dedicated vegetarians.

Vegans eat no animal meat or by products of animals, and avoid making use of animal derivatives (like leather shoes) and animal tested products (like cosmetics) in their lifestyle. Many people who have chosen a vegan lifestyle have done so for ethical reasons, especially the cruelty and exploitation involved in the making of animal products.

Vegetarianism -The health benefits of a plant-based diet

There is little disputing that an appropriately planned vegetarian diet has a wide range of health benefits. Vegetarians are reported to have a lower body mass index than non-vegetarians. They experience lower rates of death from ischaemic heart disease, show lower blood cholesterol, lower blood pressure, and lower rates of hypertension, type II diabetes and prostate and colon cancer. These are some of the adverse effects of animal products eaten in excess over a lifetime.

A vegetarian diet offers a variety of nutritional benefits. It is a diet low in saturated fat, cholesterol, and animal protein, whilst being higher in carbohydrates, fibre, magnesium, potassium, folate, boron and the antioxidants vitamins C and E, and cancer-preventing phytochemicals, or plant chemicals. Due to the emphasis on fresh fruits and vegetables, this diet tends to be more alkaline unlike the acidity produced by eating animal proteins. Acidity in the body causes calcium to leach from the bones to act as a buffer, thereby contributing to bone demineralisation. Poor quality animal proteins can contain hormones and antibiotics, adversely affecting our health.

Vegetarianism -Nutrient deficiencies to watch out for in a vegan/ vegetarian diet

Whilst a vegetarian based diet has many advantages, it can also contain low amounts of certain essential nutrients, if it is not sufficiently balanced:

Vitamin B12

It has been argued that vegans are no more vulnerable to vitamin B12 deficiency than meat eaters. This is because vegans have a more favourable balance of gut flora that produces sufficient B12.

Sources - Occurs naturally only in animal products. Can obtain it from dairy foods and eggs. Soil is a rich source of vitamin B12, and it is thought that lightly washed, freshly harvested vegetables were a viable source. However modern food practices and the sterile nature of food and the environment do not make this a viable source.

Required for -DNA synthesis, red blood cell production, energy production, insulation of nerve cells, homocysteine metabolism, fat burning, bone building, neurotransmitter and hormone production

Deficiencies - pernicious anaemia, can raise homocysteine levels, increasing the risk of heart disease

Vegetarian sources - fortified foods, yeast extract, fortified soya milk. Micro-algae (spirulina, chlorella and blue-green algae) is thought to be an excellent source of B12 although there is debate as to whether it is in a bio-available form to the body.

Vitamin D

Infants, children and older adults synthesize vitamin D less efficiently

Sources - primarily comes from the action of sunlight on the skin. Normally present in animal sources - butter, eggs, oily fish, milk, liver. Also present in some fortified margarine.

Required for - bone formation - maintenance of plasma calcium levels. It is important in the prevention of osteoporosis.

Deficiencies - rickets (in children), osteoporosis, diarrhoea, insomnia, nervousness and muscle twitches

Vegetarian sources - sunshine, supplement with a daily multivitamin

Vitamin A

Preformed vitamin A is only found in animal foods. Vegetarians rely on vitamin A from consumption and conversion of dietary beta carotene. The inclusion of 3 servings per day of yellow/ orange fruit and vegetables or dark green leafy vegetables is thought to be sufficient to meet Vitamin A requirements.

Vitamin B2

Animal meat is a good source of vitamin B2 and non-meat eaters might have a deficiency of this vitamin. Non meat sources of vitamin B2 include: almonds, mushrooms, asparagus, bananas, beans, broccoli, figs, kale, lentils, peas, sesame seeds, sweet potatoes, tofu, tempeh and wheat germ.

Calcium

Calcium is a mineral vital for nerve transmission and muscular contraction and healthy teeth and bones. A strict vegan diet can be deficient in this mineral, if a wide-enough range of calcium-rich greens, vegetables, nuts and beans are not consumed. Boron, a mineral which is effective in reducing calcium loss, is found mainly in fruits, vegetables and nuts. Higher intake of potassium and vitamin K amongst vegetarians is a benefit in safeguarding against bone loss.

Vegetarian sources of calcium- broccoli, collards, kale, bok choy, turnip greens, okra, nuts, seeds, pulses, fortified soya products, tofu, figs, blackstrap molasses. A number of these foods are also excellent sources of magnesium which is needed for calcium absorption.

Iron

Haem-iron found in animal blood, especially red meat, is absorbed five times more efficiently than plant sources which contain only non-haeme iron. However, excess haem iron can act as a pro-oxidant. This possibly explains the link between arterial damage and colorectal cancer seen in meat eaters.

The main inhibitor of iron absorption in a vegetarian diet, is phytates found in wheat. However, vitamin C which is typically higher in a plant based diet, consumed at the same time as iron, can help to improve absorption.

Vegetarian sources - tofu, kidney beans, lentils, pumpkin seeds, quinoa, watercress, parsley, mushrooms, dried fruits, potato skin, asparagus, beetroots, oatmeal, blackstrap molasses

Zinc

Animal protein is believed to enhance the absorption of zinc, whereas phytates (in wheat products) bind to and excretes zinc. It is thought that zinc is likely to be lower in a vegetarian diet.

Vegetarian sources - aduki beans, navy beans, cashew nuts, pumpkin seeds, sunflower seeds, ginger root, Brazil nuts

Iodine

Studies suggest that vegans who do not consume iodise salt or sea vegetables are at risk of iodine deficiency. The fact that vegan diets are also often high in goitrogens (foods which inhibit thyroid function), such as soya products and cruciferous vegetables, suggests a possible issue in relation to thyroid insufficiency.

Vegetarian sources - kelp, sea vegetables and iodised salt

Omega 3 EFA's

Vegetarian diets can be low in Omega 3 fatty acids and their derivative EPA and DHA, sourced directly from fish oils. It is therefore recommended that vegetarians include good sources of Omega 3 sources such as flaxseed, pumpkin and walnut in their diets. Zinc is one of the co-factors required for the conversion of omega 3 fatty acids to DHA and EPA. If there is a deficiency of zinc in the body, it is now possible to obtain vegan sources of DHA, derived from micro-algae.

Protein

There is absolutely no reason why a vegan diet cannot satisfy the protein needs of the body. Vegan sources of protein include beans and pulses, soya based products, nuts and seeds and grains. Some vegan foods such as quinoa are a good source of all eight essential amino acids. A combination of a complex carbohydrate and a plant protein (i.e. brown rice and beans) at the same meal, or eaten over the course of the day, will create a complete protein.

A well-planned vegan or vegetarian lifestyle has many benefits and can be suitable for all stages of life. However, it is important to ensure a balanced diet that supplies all the nutrients needed to stay healthy. Blood tests can be done to assess mineral levels if deficiencies are suspected. Good quality, suitable supplements can be taken to address any nutrients that may be lacking.

Introduction to Vegetarianism


If you're reading this article, you're probably thinking about becoming a vegetarian, or maybe you're just curious about a vegetarian diet since you've started to hear about it so much. Vegetarian diets are increasingly being considered healthier than meat-based diets, and nutritionally adequate. Vegetarian diets also provide benefits in the prevention and treatment of certain diseases, apart from offering general nutritional benefits like lower levels of saturated fat and cholesterol.

The founders of the British Vegetarian Society coined the word 'Vegetarian' in 1847. It comes from the Latin word "vegetus", which means "whole, sound, or fresh". Originally the word vegetarian meant a kind of lifestyle that was balanced and moral. However, the word has now evolved to mean a kind of diet in which meat, fish, or fowl are excluded.

There are several variants of the vegetarian diet. Some exclude eggs; some also exclude animal products like milk and dairy products, honey, etc. Veganism is an example of a kind of diet that excludes all animal products from the diet, and even from attire (for example leather, silk, feathers, wool, etc.). The primary types of vegetarian diets are as follows:

• Ovo-lacto vegetarianism: The vegetarian diet that includes eggs, dairy products, and honey falls in this category.

• Lacto vegetarianism: This vegetarian diet excludes eggs, but includes dairy products and honey.

• Ovo vegetarianism: People following this category of vegetarian diet exclude dairy products from their diets, but include eggs and honey.

• Veganism: This type of vegetarian diet excludes eggs, milk and dairy products, as well as honey.

• Other variations include fruitarianism, which is a diet only of fruits, nuts, and seeds, and raw veganism, which is a diet of fresh and uncooked fruits, vegetables, and nuts.

There are many reasons for people to be vegetarian. For many, it is part of their religious and cultural traditions. For example, Hinduism holds vegetarianism as the ideal, because of its emphasis on non-violence. Hindus also believe that non-vegetarian food is detrimental to spiritual development, and hence a large number of Hindus are vegetarians. Jainism and Buddhism also instruct their followers to avoid meat. Some people choose vegetarianism because they were raised in a vegetarian household, or because their partner was vegetarian.

Many people choose vegetarianism for health reasons. According to the American Dietetic Association of Canada, vegetarian diets lead to lower levels of saturated fat, cholesterol, and animal protein in the body, while increasing carbohydrate, fiber, magnesium, potassium, and vitamin C and E levels (www.dietitians.ca/news/downloads/Vegetarian_Food_Guide_for_NA.pdf). Some studies have suggested that a vegetarian diet keeps body weight under control and reduces the risk of heart disease. Research also suggests a link between cancer of the colon, rectum, and breast to meat eating.

In developed countries, many people are converting to vegetarianism because of ethical and environmental reasons. Many people are against the factory farming of animals, and their treatment as commodities. A belief in animal rights, and an aversion to inflicting pain on other living creatures is leading people to vegetarianism. Others are concerned that the production of meat for mass consumption is environmentally unsustainable and hence take up vegetarianism. It is pointed out that animal farming leads to extremely high consumption of fossil fuels and water resources, and leads to emissions of greenhouse gases. One study estimated that animal farming produces 65% of human-related nitrous oxide, and 37% of all human-related methane ([http://www.virtualcentre.org/en/library/key_pub/longshad/A0701E00.htm]), which have far greater potential for global warming than carbon dioxide.

Many vegetarians also make vegetarianism a basis in their choice of textiles. Such people eschew the use of leather, silk, and even wool. Because these textiles form such an important part of most footwear, clothing, and accessories, alternatives made of synthetic materials, like Vegan leather, or polar fleece as a substitute for wool, are available in the market.

A vegetarian diet can be extremely healthy and nutritious. If one includes a lot of variety-lots of whole grains, vegetables, fruits, nuts, and seeds- it can provide all the essential nutrients required for a healthy body. Vegetarianism is the way to go for a healthy body, and a healthy, sustainable environment on the planet.
