Cancer prevention diet tip #3: Cut down on meat

Research shows that vegetarians are about fifty percent less likely to develop cancer than those who eat meat. So what’s the link between meat and cancer risk? First, meat lacks fiber and other nutrients that have been shown to have cancer-protective properties. What it does have in abundance, however, is fat—often very high levels of saturated fat. High-fat diets have been linked to higher rates of cancer. And saturated fat is particularly dangerous. Finally, depending on how it is prepared, meat can develop carcinogenic compounds.
Making better meat and protein choices

You don’t need to cut out meat completely and become a vegetarian. But most people consume far more meat than is healthy. You can cut down your cancer risk substantially by reducing the amount of animal-based products you eat and by choosing healthier meats.

    1. Keep meat to a minimum. Try to keep the total amount of meat in your diet to no more than fifteen percent of your total calories. Ten percent is even better.
    2. Eat red meat only occasionally. Red meat is high in saturated fat, so eat it sparingly.
    3. Reduce the portion size of meat in each meal. The portion should be able to fit in the palm of your hand.
    4. Use meat as a flavoring or a side, not the entrée. You can use a little bit of meat to add flavor or texture to your food, rather than using it as the main element.
    5. Add beans and other plant-based protein sources to your meals.
    6. Choose leaner meats, such as fish, chicken, or turkey. If possible, buy organic.
    7.  Avoid processed meats such as hotdogs, sausage, deli meats, and salami.

Cancer prevention diet tip #2: Bulk up on fiber

Cancer prevention diet tip #2 – Bulk up on fiberAnother benefit of eating plant-based foods is that it will also increase your fiber intake. Fiber, also called roughage or bulk, is the part of plants (grains, fruits, and vegetables) that your body can’t digest. Fiber plays a key role in keeping your digestive system clean and healthy. It helps keep food moving through your digestive tract, and it also moves cancer-causing compounds out before they can create harm.

Fiber is found in fruits, vegetables, and whole grains. In general, the more natural and unprocessed the food, the higher it is in fiber. There is no fiber in meat, dairy, sugar, or “white” foods like white bread, white rice, and pastries.
Simple ways to add more fiber to your diet:

    Use brown rice instead of white rice
    Substitute whole-grain bread for white bread
    Choose a bran muffin over a croissant or pastry
    Snack on popcorn instead of potato chips
    Eat fresh fruit such as a pear, a banana, or an apple (with the skin)
    Have a baked potato, including the skin, instead of mashed potatoes
    Enjoy fresh carrots, celery, or bell peppers with a hummus or salsa, instead of chips and a sour cream dip
    Use beans instead of ground meat in chili, casseroles, tacos, and even burgers (bean burgers can taste great)

High-fiber, cancer-fighting foods

Whole grains
   

whole-wheat pasta, raisin bran, barley, oatmeal, oat bran muffins, popcorn, brown rice, whole-grain or whole-wheat bread

Fruit
   

raspberries, apples, pears, strawberries, bananas, blackberries, blueberries, mango, apricots, citrus fruits, dried fruit, prunes, raisins

Legumes
   

lentils, black beans, split peas, lima beans, baked beans, kidney beans, pinto, chick peas, navy beans, black-eyed peas

Vegetables
   

broccoli, spinach, dark green leafy vegetables, peas, artichokes, corn, carrots, tomatoes, Brussels sprouts, potatoes

Cancer prevention diet tip #1: Focus on plant-based foods
Why plant-based foods are cancer-fighting powerhouses

It comes down to this: Plants have less fat, more fiber, and more cancer-fighting nutrients. These three elements work together to support your immune system and help your body fight off cancer. 

The best diet for preventing or fighting cancer is a predominantly plant-based diet that includes a variety of vegetables, fruits, and whole grains. A plant-based diet means eating mostly foods that come from plants: vegetables, fruits, nuts, grains, and beans.

The less processed these foods are—the less they’ve been cooked, peeled, mixed with other ingredients, stripped of their nutrients, or otherwise altered from the way they came out of the ground—the better.

There are many ways to add plant-based foods to your diet. A nice visual reminder is to aim for a plate of food that is filled at least two-thirds with whole grains, vegetables, beans, or fruit. Dairy products, fish, and meat should take up no more than a third of the plate. Keep in mind that you don’t need to go completely vegetarian. Instead, focus on adding “whole” foods, which are foods close to their original form. Just as important, try to minimize or reduce the amount of processed foods you eat. Eat an apple instead of drinking a glass of apple juice, for example. Or enjoy a bowl of oatmeal with raisins instead of an oatmeal raisin cookie.
Simple tips for getting more plant-based foods in your diet

    Breakfast: Add fruit and a few seeds or nuts to your whole grain breakfast cereal (such as oatmeal).
    Lunch: Eat a big salad filled with your favorite beans and peas or other combo of veggies. Always order lettuce and tomato (plus any other veggies you can) on your sandwiches. Order whole grain bread for your sandwiches. Have a side of veggies like cut up carrots, sauerkraut, or a piece of fruit.
    Snacks: Fresh fruit and vegetables. Grab an apple or banana on your way out the door. Raw veggies such as carrots, celery, cucumbers, jicama, peppers, etc. are great with a low-fat dip such as hummus. Keep trail mix made with nuts, seeds, and a little dried fruit on hand.
    Dinner: Add fresh or frozen veggies to your favorite pasta sauce or rice dish. Top a baked potato with broccoli and yogurt, sautéed veggies, or with salsa. Replace creamy pasta sauces, with sautéed vegetables or tomato sauce made with healthy olive oil.
    Dessert: Choose fruit instead of a richer dessert. Or a single square of dark chocolate.

Departments / Should We worry about nuclear power?
« on: April 09, 2014, 12:49:58 PM »
Nuclear power stations are not atomic bombs waiting to go off, and are not prone to "meltdowns".
There is a lot of U-238 in there slowing things down - you need a high concentration of U-235 to make a bomb.
If the reactor gets too hot, the control rods are lowered in and it cools down.
If that doesn't work, there are sets of emergency control rods that automatically drop in and shut the reactor down completely.
   
With reactors in the UK, the computers will shut the reactor down automatically if things get out of hand (unless engineers intervene within a set time). At Chernobyl, in Ukraine, they did not have such a sophisticated system, indeed they over-rode the automatic systems they did have. When they got it wrong, the reactor overheated, melted and the excessive pressure blew out the containment system before they could stop it. Then, with the coolant gone, there was a serious fire. Many people lost their lives trying to sort out the mess. A quick web search will tell you more about this, including companies who operate tours of the site.

If something does go wrong in a really big way, much of the world could be affected - some radioactive dust (called "fallout") from the Chernobyl accident landed in the UK. That's travelled a long way.

With AGR reactors (the most common type in Britain) there are additional safety systems, such as flooding the reactor with nitrogen and/or water to absorb all the neutrons - although the water option means that reactor can never be restarted.

So should I worry? I think the answer is "so long as things are being done properly, I don't need to worry too much. The bit that does worry me is the small amount of high-level nuclear waste from power stations. Although there's not much of it, it's very, very dangerous and we have no way to deal with it apart from bury it and wait for a few thousand years..


 Advantages


    Nuclear power costs about the same as coal, so it's not expensive to make.

    Does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect.

    Produces huge amounts of energy from small amounts of fuel.

    Produces small amounts of waste.

    Nuclear power is reliable.

Disadvantages

    Although not much waste is produced, it is very, very dangerous.
    It must be sealed up and buried for many thousands of years to allow the radioactivity to die away.
    For all that time it must be kept safe from earthquakes, flooding, terrorists and everything else. This is difficult.

    Nuclear power is reliable, but a lot of money has to be spent on safety - if it does go wrong, a nuclear accident can be a major disaster.
    People are increasingly concerned about this - in the 1990's nuclear power was the fastest-growing source of power in much of the world. In 2005 it was the second slowest-growing.

Is it renewable?

Nuclear energy from Uranium is not renewable.
Once we've dug up all the Earth's uranium and used it,
there isn't any more.

Departments / Nuclear power: Energy from splitting Uranium atoms

Nuclear power:

Energy from splitting Uranium atoms




Nuclear power is generated using Uranium, which is a metal mined in various parts of the world.

The first large-scale nuclear power station opened at Calder Hall in Cumbria, England, in 1956.

Some military ships and submarines have nuclear power plants for engines.

Nuclear power produces around 11% of the world's energy needs, and produces huge amounts of energy from small amounts of fuel, without the pollution that you'd get from burning fossil fuels.
How it works:

The main bit to remember:

Nuclear power stations work in pretty much the same way as fossil fuel-burning stations, except that a "chain reaction" inside a nuclear reactor makes the heat instead.

The reactor uses Uranium rods as fuel, and the heat is generated by nuclear fission: neutrons smash into the nucleus of the uranium atoms, which split roughly in half and release energy in the form of heat.

Carbon dioxide gas or water is pumped through the reactor to take the heat away, this then heats water to make steam.

The steam drives turbines which drive generators.
   

Modern nuclear power stations use the same type of turbines and generators as conventional power stations.

In Britain, nuclear power stations are often built on the coast, and use sea water for cooling the steam ready to be pumped round again. This means that they don't have the huge "cooling towers" seen at other power stations.

The reactor is controlled with "control rods", made of boron, which absorb neutrons. When the rods are lowered into the reactor, they absorb more neutrons and the fission process slows down. To generate more power, the rods are raised and more neutrons can crash into uranium atoms.

More:

Natural uranium is only 0.7% "uranium-235", which is the type of uranium that undergoes fission in this type of reactor.

The rest is U-238, which just sits there getting in the way. Modern reactors use "enriched" uranium fuel, which has a higher proportion of U-235.

The fuel arrives encased in metal tubes, which are lowered into the reactor whilst it's running, using a special crane sealed onto the top of the reactor.

With an AGR or Magnox station, carbon dioxide gas is blown through the reactor to carry the heat away. Carbon dioxide is chosen because it is a very good coolant, able to carry a great deal of heat energy. It also helps to reduce any fire risk in the reactor (it's around 600 degrees Celsius in there) and it doesn't turn into anything nasty (well, nothing long-lived and nasty) when it's bombarded with neutrons.


You have to be very careful about the materials you use to build reactors - some materials will turn into horrible things in that environment. If a piece of metal in the reactor pressure vessel turns brittle and snaps, you're probably in trouble - once the reactor has been built and started you can't go in there to fix anything..

Uranium itself isn't particularly radioactive, so when the fuel rods arrive at the power station they can be handled using thin plastic gloves. A rod can last for several years before it needs replacing.
It's when the "spent" fuel rods are taken out of the reactor that you need the full remote-control robot arms and Homer Simpson equipment

Departments / Quantum Yoga
« on: April 09, 2014, 12:31:57 PM »
                     Quantum Yoga is the exercise for smart people. It yields optimum output but requires minimum input. Most forms of exercise only strengthen muscles. Quantum Yoga tones the muscles, keeps internal glands and organs healthy, makes the mind keen and alert, and initiates mental and physical healing.

This simpler version of ancient yoga has the added benefits of visualization and is good for your mind, body and soul.
Meditation keeps our mind tranquil and joyful. As a result the bodies healing process is accelerated. However, it is nearly impossible to attain optimum health of mind, body and spirit without some form of physical exercise. This is why the ancient spiritual masters incorporated various forms of exercise in their lifestyle.

Departments / The Five Pillars of Quantum Health
« on: April 09, 2014, 12:23:19 PM »
These five vital functions set the rhythm for the rest of our physiological activities.
 
Breathing:
Breathing is the fundamental rhythm of life. This fundamental rhythm controls every other rhythm in our body. Breathing exercises or pranayama were an integral part of the daily health regimen of the yogis.
For abundant oxygen supply breathe in the following manner 19 times in a row, five times a day. First, slowly inhale through your nostrils while gradually expanding your chest. After your chest has expanded completely, exhale through your mouth. Count one. Repeat the whole process, count 2. After counting up to 19 in this way, return to your normal breathing. If you practice this five times a day, every cell in your body will get an abundant supply of oxygen. All your lethargy and weariness will be disappear. You will be lively, energetic and able to work longer hours.
 
Eating:
The second Quantum foundation of health is eating. You can eat anything that your faith and your taste allow. However, natural and healthy food, which we call Quantum food, will greatly improve your health. The section on Healthy Eating Habits discusses in detail what to eat, how much to eat, and also when and how to eat.
 
Exercise:
In the recent years many of us have become more conscious about the importance of exercise. However, the wrong kind of exercise can harm us instead of helping us. The best kind of exercise is Quantum yoga, which is the latest version of yoga. The second best is walking. Exercise or walk for about 25/30 minutes everyday. When you walk, try to walk at a speed of at least four miles per hour.
 
Digestion:
Proper digestion is vital for Quantum Health. For those of us who face problems with digestion it is important to realize that the cause of indigestion in most cases is mental rather than physical. The acid created in the stomach is so powerful that it can eat through iron. It is so powerful that the inner lining of the stomach is renewed every five days so that the stomach itself is not digested.
So everyday, before you eat, say, “I will enjoy whatever I eat, and I will digest everything perfectly.”
Also, after you have eaten rich food, chew a piece of lemon rind, which is a natural digester.
 
Excretion:
To ensure that the body is able to remove all it waste eat lots of leafy and fibrous vegetables and drink lots of water. This will also lessen chances of intestinal cancer.
When you take a shower or bath, always keep the water temperature cooler then your body temperature. Based on 19 years of research, Dr. Kakker has found that taking baths in hot water weakens the body’s immune system, while bathing in cool water has the opposite effect. Even during winter, or in areas with cold weather, make sure the temperature of the water is slightly cooler than normal body temperature.

How To Prevent Old Age And Maintain Youthfulness
Problems of Ageing:
Death is certain. But everybody would like to maintain good Health till the last breath. The current of life is discharged from the body from the right arm. The control point of this current is wrist and the elbow. By giving two minutes treatment intermittent pressure on this point, the excess discharge of youthfulness for longer period and delay old age. This treatment is must for all men and women after the age of 40.
It is interested to note that regular treatment on this point even by aged people will greatly benefit them and they will start felling more energetic, younger and less tired.
Planning:
You have learnt how to prevent old age and remain youthful, it is almost necessary to have proper plans for the retirement. Activities of your choice must be increased; new hobbies common to both or complimentary to each other must be developed. Start taking interest I reading, writing, and fine arts, music, painting, gardening, much more.  Moreover move around a lot and see the world and meet people. You will feel a sense of oneness with them.
The most important is that, up till now, your activities were centered on you; start taking interest in other welfare and find new avenues of great joy. Reduce your expectation and try to fulfill others expectations.
Food:
It is observed by the medical world that after the age 60 years, the heart and liver start functioning slower and slower. As such, rest after meals is most necessary. And a change in diet is a must. Try to reduce cooked food as much as possible. Increase the intake of green juices, fruit juices, green salads, fruits and yoghurt, etc. which are easily digestible and which will give you enough energy. Moreover, light exercise, walking/ swimming for 40 minutes are must. Very soon you will be near nature and every morning will bring you new joys and new meaning of life. And you will feel young, sing merrily like a bird and will feel confident, of living for 100 years.
