FRUITS RELATED WITH HUMAN BODY


CARROT – EYE

SLICE a carrot and it looks just like an eye, right down to the pattern of the iris. It’s a clear clue to the importance this everyday veg has for vision. Carrots get their orange colour from a plant chemical called betacarotene, which reduces the risk of developing cataracts. The chemical also protects against macular degeneration an age-related sight problem that affects one in four over-65s. It is the most common cause of blindness in Britain. But popping a betacarotene pill doesn’t have the same effect, say scientists at Johns Hopkins Hospital in Baltimore

WALNUT – BRAIN

The gnarled folds of a walnut mimic the appearance of a human brain - and provide a clue to the benefits. Walnuts are the only nuts which contain significant amounts of omega-3 fatty acids. They may also help head off dementia. An American study found that walnut extract broke down the protein-based plaques associated with Alzheimer’s disease. Researchers at Tufts University in Boston found walnuts reversed some signs of brain ageing in rats. Dr James Joseph, who headed the study, said walnuts also appear to enhance signalling within the brain and encourage new messaging links between brain cells.

TOMATO – HEART

A TOMATO is red and usually has four chambers, just like our heart. Tomatoes are also a great source of lycopene, a plant chemical that reduces the risk of heart disease and several cancers. The Women’s Health Study — an American research programme which tracks the health of 40,000 women — found women with the highest blood levels of lycopene had 30 per cent less heart disease than women who had very little lycopene. Lab experiments have also shown that lycopene helps counter the effect of unhealthy LDL cholesterol. One Canadian study, published in the journal Experimental Biology and Medicine, said there was “convincing vidence’ that lycopene prevented coronary heart disease.

GRAPES – LUNGS

Our lungs are made up of branches of ever-smaller airways that finish up with tiny bunches of tissue called alveoli. These structures, which resemble bunches of grapes, allow oxygen to pass from the lungs to the blood stream. One reason that very premature babies struggle to survive is that these alveoli do not begin to form until week 23 or 24 of pregnancy. A diet high in fresh fruit, such as grapes, has been shown to reduce the risk of lung cancer and emphysema. Grape seeds also contain a chemical called proanthocyanidin, which appears to reduce the severity of asthma triggered by allergy.

CHEESE – BONES

A nice ‘holey’ cheese, like Emmenthal, is not just good for your bones, it even resembles their internal structure. And like most cheeses, it is a rich source of calcium, a vital ingredient for strong bones and reducing the risk of osteoporosis later in life. Together with another mineral called phosphate, it provides the main strength in bones but also helps to ‘power’ muscles. Getting enough calcium in the diet during childhood is crucial for strong bones. A study at Columbia University in New York showed teens who increased calcium intake from 800mg a day to 1200mg – equal to an extra two slices of cheddar - boosted their bone density by six per cent.

GINGER – STOMACH

Root ginger, commonly sold in supermarkets, often looks just like the stomach. So it’s interesting that one of its biggest benefits is aiding digestion. The Chinese have been using it for over 2,000 years to calm the stomach and cure nausea, while it is also a popular remedy for motion sickness. But the benefits could go much further.Tests on mice at the University of Minnesota found injecting the chemical that gives ginger its flavour slowed down the growth rate of bowel tumours

BANANA (SMILE) – DEPRESSION

Cheer yourself up and put a smile on your face by eating a banana. The popular fruit contains a protein called tryptophan. Once it has been digested, tryptophan then gets converted in a chemical neurotransmitter called serotonin. This is one of the most important mood-regulating chemicals in the brain and most anti-depressant drugs work by adjusting levels of serotonin production. Higher levels are associated with better moods.

MUSHROOM – EAR

Slice a mushroom in half and it resembles the shape of the human ear. And guess what? Adding it to your cooking could actually improve your hearing. That’s because mushrooms are one of the few foods in our diet that contain vitamin D. This particular vitamin is important for healthy bones, even the tiny ones in the ear that transmit sound to the brain.

BROCCOLI – CANCER

Close-up, the tiny green tips on a broccoli head look like hundreds of cancer cells. Now scientists know this disease-busting veg can play a crucial role in preventing the disease. Last year, a team of researchers at the US National Cancer Institute found just a weekly serving of broccoli was enough to reduce the risk of prostate cancer by 45 per cent. In Britain, prostate cancer kills one man every hour.

Why Exercise is Good for Your Weight

A recent Time magazine article, "Why Exercise Won't Make You Thin," is misleading at best. Exercise is critical to losing weight and maintaining a healthy weight, especially when paired with healthy eating habits. Countless studies, numerous experts who study exercise, and the millions of people who have lost weight all attest to the fact that working out works.


1. Exercise zaps belly fat

Regular moderate to high intensity aerobic exercise has the greatest impact on reducing abdominal fat -- the dangerous fat that increases your risk of diabetes and heart disease.


2. Exercise controls calories

You need to burn more calories than you consume in order to lose weight. Regular exercise uses up excess calories that would otherwise be stored as fat.


3. Exercise keeps lost pounds MIA

Ninety percent of people who have successfully lost weight and kept it off for a year do about an hour of physical activity a day.

4. Exercise boosts metabolism

You'll lose fat when you diet without exercising, but you'll also lose muscle, which means you'll burn fewer calories. The more muscle you have, the higher your metabolism and the more calories you'll burn.


5. Exercise does more than the scale shows

If you gain 3 pounds of lean muscle and lose 4 pounds of fat, you've actually experienced a 7-pound improvement in your body condition, despite the scale only showing 1 pound of weight loss..


6. Exercise curbs emotional eating

Working out has been proven time and time again to help regulate mood, which has a direct effect on people who eat when they're stressed or upset.


7. Exercise creates a healthy chain reaction

Healthy habits tend to cluster together.. When people make positive changes, like getting more exercise, they tend to work on other health improvements as well, such as eating better.


8. Exercise brings on the fun

Rock-climbing is more exciting than eating a celery stick. That's why it's sometimes easier to be active to stay slim than to maintain a strict diet.


9. Exercise stops hunger

People who exercise and diet are actually less hungry than those who only diet, according to at least one study.

10. Exercise ups energy

Regular physical activity increases stamina by boosting your body's production of energy-promoting neurotransmitters. That gives you even more motivation to get moving and shed pounds.
