veg diet 20120 - Part 7

When Milk Is Not A Healthy Food
Milk is often praised as a perfect food which contains all the protein, fats and minerals that are needed for a healthy life. It is often recommended that we drink a pint of milk a day.
Milk is, after all, the only food for the young of mammals. It seems natural that we should rely on it and other dairy produce manufactured from milk as a source of nutrition.
But matters are not so straightforward. Cows' milk is not a natural food for human beings. For human infants it can be harmful unless modified as it is infant formula.
Older children can often tolerate milk, but many adults lose the stomach enzyme that allows them to digest milk. In northern latitudes many adults retain that enzyme and they can digest milk. But in other parts of the world adults seldom have the ability to do so.
As societies become more diverse it is not uncommon to encounter individuals who cannot tolerate milk in their diet.

Even those of us who can drink milk need to be aware of health concerns that are linked to a high consumption of milk and dairy produce. Full cream milk can help to raise the body's level of cholesterol because it contains animal fat. This is even more true of cheese, butter and cream, which contain a higher proportion of fat.
Skimmed milk may be answer to this problem but a high consumption of dairy foods has been associated with various forms of cancer. Breast cancer, ovarian cancer and prostate cancer have all been linked to dairy foods. A Harvard study showed that if too much dairy produce is consumed the body's enzymes may not be able to break down the lactose that milk contains. This can build up in the blood stream and contribute to cancer formation in the body's organs.
Milk produced under modern factory farming conditions is a long way from the milk that used to be available. Cows do not necessarily graze on grass. They may be kept indoors and fed on concentrates. This has several consequences for their milk. Milk from grass fed cattle is typically high in vitamin D. But milk from cattle reared indoors is not.

Vitamin D is essential if we are to utilize calcium in bone growth and repair. We may be drinking milk in the belief that it helps us avoid osteoporosis when in fact it does not. Milk is not a reliable source of either vitamin D or calcium.
Milk can also contain high levels of hormones such as IGF-I. This substance has been linked to a number of cancers.
It is possible to avoid milk and still obtain sufficient nutrients from a variety of other sources. Leafy green vegetables and whole grains are a good source of calcium. Vegetables such as carrots are a good source of vitamin D. Soya products contain no animal fat and are often fortified with both vitamin D and calcium.

The Importance Of Eating A Healthful Vegetarian Diet
So often when people say they are vegetarian they mean that they do not eat meat. But being a vegetarian is about more than just not eating meat. It is possible to be a vegetarian in the sense of not eating meat and eat a very unhealthy diet indeed.
A vegetarian diet may by high in cholesterol if it relies too much on cheese and eggs. It may be low in fibre if it is based on refined grain products like white bread, white pasta and white rice. If it lacks fresh vegetables you diet will be deficient in vitamins and minerals. You may vegetarian but you may not be eating a healthful vegetarian diet.
Going vegetarian is about more than just not eating meat. It means taking a positive decision to eat a wide range of foods that provide a balanced mixture of nutrients.
It is important to plan the change to a vegetarian diet. This may mean buying some new equipment for your kitchen. If you are used to eating convenience foods you may need to buy some basic items.
The next step is to plan your meals. Not all vegetarian meals rely on cheese, eggs and milk for protein. These are useful ingredients in a vegetarian diet but not by any means essential. It is perfectly possible to get enough protein by combining grains with pulse such as peas, beans and lentils. A bowl of lentil soup with a slice of bread provides all the essential amino you need. Chili beans and rice combine in the same way to create what is called a complete protein.
A diet based on pulses and whole grains has the immense of advantage of providing you with enough fibre. This is important to maintain colon health. Cancer of the colon is most common among people who eat a diet based on over-refined processed foods. Fibre is one of the key ingredients in a healthful vegetarian diet.
Switching to a high fibre diet takes a little time. Your body needs to adjust. So take things slowly at first.

A healthful vegetarian diet based on whole grains, pulses, nuts, fruits, and vegetables will also be good for your heart as it is low in fat. The fats you use in vegetarian cooking should be vegetable fats and oils such as olive oil, coconut oil or groundnut oil. There is no reason to exclude butter from a vegetarian diet especially if most of the fat you are consuming is of vegetable origin.
One of the great things about a healthful vegetarian diet is that it helps to maintain you weight at the right level. You will still pile on the pounds if you binge on ice cream but a really healthful vegetarian diet leaves you feeling satisfied so that you are less likely to overindulge in sweet things.

Don't Be A Lazy Vegetarian
Vegetarianism has become big business. The shelves of our supermarkets are full of products aimed at the vegetarian. They all look so convenient and we all need to save time. We are inevitably tempted to be a bit lazy sometimes and cut corners.
But vegetarians need to be aware what is in those handy little packages or they could be putting their health at risk. So don't be a lazy vegetarian in the supermarket: read those labels.
You need to check how much sugar is in the product, how much fat and whether refined carbohydrates have been used. A little bit of refined flour, the occasional sweet or fatty treat are not in themselves bad for a vegetarian. But these substances become a problem when they make up a large part of the vegetarian diet.
Even a vegetarian can get fat if they eat enough fat, sugar and refined carbohydrate. As a vegetarian, you should train your palate and that of your children to expect less of these foods and the instant sugar rush that goes with them.
Many of the fats used in commercial vegetarian foods are what is called transfatty acids. These are associated with an elevated risk of cancer. So even if the fats used in a vegetarian product are derived from vegetable sources they may have been modified so much in the manufacturing process that they are no longer healthy.
Of course, vegetarians lead busy lives and there are times when we need a quick snack or a meal in hurry. In these situations opt for healthy alternative. A bowl of whole meal cereal will fill that hungry gap before the evening meal when you come home. Keep a good range of fresh fruits on hand. This is natural grab and go vegetarian food.
Vegetarian food does not always take a long time to cook and prepare. Red split lentils take 10 minutes to cook and can become the basis of all kinds of curries, soups, stews and burgers.

If you keep some cooked pulse on hand in the fridge you can rustle up a vegetarian meal very quickly. Or cook twice as much as you need when you have the time and freeze it for later. A little planning allows a vegetarian to be lazy in a healthy way.
May be when you feel that vegetarian cooking it just too slow you should ask yourself "What's the hurry?" Vegetarian food should not be a quick refueling stop. Set out a platter of vegetable sticks and olives with a hummous dip. Cut up a loaf of whole meal bread. Take time to discuss the events of the day. By the time you have done that your main vegetarian meal of the evening will be ready.

Alternative Sources Of Protein For The Vegetarian
In a conventional diet protein is obtained from meat, fish, eggs, milk and dairy products such as cheese. These all contain complete proteins that contain all the essential amino acids that are needed for the human body. A vegetarian diet must derive protein from other sources.
Protein is found in many vegetable sources. Some of these vegetable proteins are complete in that they contain all the essential amino acids just like animal protein. Others are incomplete and must be combined together to produce a complete protein that the body can use.
Most plant foods contain some protein. A vegetarian who eats a wide variety of foods will consume sufficient protein in the course of day.
Nuts and seeds are an under appreciated source of protein. They can be added to a wide range of sweet and savory vegetarian dishes.
Soya beans are source of complete protein and for that reason soya products are an important part of a vegetarian diet. Commercially manufactured soya based meat substitutes are now widely available in supermarkets. They come in variety of forms and are often made into pies, burgers, sausages and other ready prepared products that offer the busy vegetarian a convenience food.
Soya milk can be found in most chiller cabinets next to the cows' milk. You will also find soya yoghurts and soya cheeses. A more traditional soya product is tofu which has long been used in Chinese cooking.
Another meat substitute is mycoprotein which is made from a variety of fungus. Like soya protein it is sold in various forms that can be used in a range of recipes. You will also find it in ready made products often sold under the brand name "Quorn."
Beans, peas and lentils, known collectively as pulse, make up one of the major sources of protein for a vegetarian. They are incomplete proteins and must be combined with other incomplete proteins, such as grains, or complete proteins, such as eggs or milk, to make a complete protein food. Usually this is done in one dish such as beans and rice or beans on toast, but this is not always necessary as the body can store protein and combine it later.

Three Health Advantages Of A Vegetarian Diet
A vegetarian diet offers a number of health advantages when compared to the typical diet that is eaten by the majority of people in the rich industrial countries. The healthy character of a vegetarian diet derives from the fact that it is rich in fruit and vegetables, contains large amounts of fibre and is low in animal fat.
In recent years the problems of heart disease, obesity, diabetes, the degenerative diseases of old age and cancers have been on the increase. Provided it is well planned, a vegetarian diet addresses all the modern health problems.
It is possible to become obese on a vegetarian diet, but an overweight vegetarian is a rarity. A vegetarian diet is likely to include many slow release carbohydrates, such as brown rice, whole meal bread and root vegetables, that raise the body's blood sugar level slowly. This has major implications for both obesity and type 2 diabetes.
Much of the fat in a vegetarian diet is derived from nuts and seeds which contain essential fatty acids known as omega 3, 6 and 9. These essential fatty acids do not raise cholesterol levels and so benefit the heart. They play a vital role in the brain and help to maintain the suppleness of joints, as well as ensuring good skin and hair.
Soya products make up an important component of a vegetarian diet. Studies show that soya actively reduced the body's cholesterol levels and so contributes to heart health.
One of the key health advantages of a vegetarian diet is its high fibre content. Fruit, vegetables and whole grains all contain fibre. Fibre is essential to maintain the health of the colon and bowels. Studies have shown that a high fibre diet is linked to a low incidence of pre-cancerous growths in the colon.
The fruit and vegetables that a vegetarian consumes contain important anti-oxidants which combat the free radicals that can cause cancer.

The Top Five Nutrients Vegetarians Lack
When you are beginning the process of converting to a vegetarian diet it is important to plan carefully. You need to make yourself familiar with the nutrient value of your food and how foods interact with one another.
A vegetarian diet can be lacking in five essential nutrients unless it is planned. These are protein, iron. calcium, zinc and vitamin B-12. In a meat based diet these are easily obtained from animal products. If dairy produce and eggs are included in a vegetarian diet these essential nutrients should not be in short supply.
If you have decided to eat a vegetarian diet, whether for reasons of health or because of ethical considerations, you need to consider where you will obtain these nutrients. It is perfectly possible for a vegetarian to derive these nutrients from vegetable sources with a little thought.
A vegetarian can obtain protein from beans, peas, lentils and other pulses. These vegetarian staples need to be mixed with grains such as rice, barley or wheat, which also contain protein, because only together do they make what is called a complete protein. A complete protein contains all the essential amino acid that are found in meat and other animal products.
Soya beans are unique among beans in containing all the essential amino acids without the addition of grains. Soya products make up an important part of a vegetarian diet for that reason. Soya milk, soya yoghurt, soya cheeses, tofu and soya meat substitutes make up an important part of a healthy vegetarian diet.
A vegetarian diet need not be lacking in protein if it contains a variety of pulse, grains, nuts and seeds. Sprinkling a few sesame seeds on a meal will increase its protein content.
It is not even necessary to include different incomplete vegetable proteins in the same meal to create a balanced protein. The body is capable of storing amino acids and combining them later.
page28image21496
Many of the commercially available soya products have calcium, zinc and vitamin B-12 added in the manufacturing process. But a vegetarian should also ensure that these nutrients are present in the rest of their diet.
Soya beans are also a good source of iron as are seeds such as pumpkin seeds. Quinoa, a seed that cooks like rice and can be used as the starch component of a meal contains iron.
Zinc is vital for growth and cell division. It is essential for reproductive health. for liver function and insulin activity. It is present in dairy foods as well as beans, lentils nuts and seeds. Chick peas are a good source of zinc, as is tahini paste. A hummous dip is more than a tasty snack it is valuable source of a nutrients in a vegetarian diet.
Calcium need not be a major problem in a vegetarian diet. If a vegetarian diet includes dairy produce it will provide enough calcium. Even for vegans it is possible to obtain calcium from plant sources. Whole meal bread is a fairly good source of calcium as are dried apricots. Baked beans and broccoli are both good sources of calcium.
Where vitamin B-12 is concerned it is only necessary to resort to supplements if eggs and milk are excluded from a vegetarian diet.

Ideas For Adding Some Variety To Your Vegetarian Lifestyle
Variety is not only good for vegetarians because the same old food can become boring but it is also necessary. Making sure that your vegetarian diet is varied is the best way to ensure that your get enough of the right nutrients.
You should never stick to one or two recipes and never be tempted to confine yourself to a few commercial products because they seem easy to prepare. If you do that you simply will not get a balanced diet and you will become bored. That is why so many vegetarians give up after a short time.
When you visit the supermarket spend time in the fresh produce section. If your usual store does not carry fresh produce go to another one or find a local supplier. Fresh fruit and vegetables are the main stay of a healthy and varied vegetarian diet.
Get to know what is in season and how to prepare it. A vegetarian should learn what fresh fruit and vegetables look like, feel like and smell like. Vegetarians who can shop in farmers' markets have an advantage. But many supermarkets are improving the range of fruit and vegetables they stock.
If you choose a variety of colors of fruit and vegetables you will automatically have a range of nutrients. Vegetarian meals should not be colorless.
The look of food is often underestimated by vegetarians. But we eat with our eyes. The sight of a plate of beautiful food sets out mouth salivating as much as the smell of new baked bread.
Speaking of new baked bread, vegetarians should learn to bake bread. A sourdough rye loaf fresh from the oven or a crusty whole meal with poppy seeds can make a simple vegetarian meal into a gourmet feast. A simple vegetarian sold or a bowl of lentil can become a complete meal with good bread.
