The findings of a new study suggest walking six miles a week is good for both :DDbody and mind...

Healthy people who walk at least six miles (9.7km) a week have bigger brains, better memories and improved mental function compared with couch potatoes, a study has found.

Among older people showing signs of forgetfulness, walking even five miles a week - a daily 20-minute trip to the shops - slowed the progression of their condition.

The findings suggest that walking is the best way of preserving both mental and physical health in old age. Research has shown that it is an ideal form of exercise for maintaining physical fitness and warding off heart disease.

Now scientists have found that it can maintain mental fitness and ward off Alzheimer's disease as well.
A 10-year study of more than 400 elderly people found that greater amounts of physical activity were associated with greater brain volume.
Dr Cyrus Raji, of the department of radiology at Pittsburgh University, who led the study, said: "Volume is a vital sign for the brain. When it decreases that means brain cells are dying. But when it remains higher brain health is being maintained."

Dr Raji added: "We found that walking five miles a week protects the brain structure over 10 years in people with Alzheimer's and mild cognitive impairment."

Healthy adults needed to walk at least six miles a week to maintain brain volume and reduce their risk of mental decline.
The results are due to be presented to the Radiological Society of North America today.

Studies have not established the effect of kiwifruit on breast cancer

Kiwifruit (Actinidia deliciosa or Actinidia chinensis deliciosa), also know as kiwi fruit, kiwi, and Chinese gooseberry, is a native of Asia rich in vitamin C, fiber and potassium, and also contains significant vitamin A and vitamin E. In addition, kiwifruit has other biologically active components, including lutein, β-carotene, fisetin, caffeic acid, alpha-linolenic acid, actinidin, coumarin, kiwellin, actinidin, quercitrin, kaempferol, and some other flavones and flavonols. Kiwifruit has been shown to improve the cholesterol profile of human subjects. Kiwifruit has also been shown to have antioxidant, laxative, antifungal, antiviral, antibacterial, and cardiovascular protective effects.

Cancer-related effects of eating kiwifruit

Kiwifruit consumption has been found to enhance markers of immune response in laboratory mice. Regular kiwifruit consumption has also been shown in several studies to significantly increase the ability of the body to repair DNA breakage by free radicals. Fisetin, a component of kiwifruit, has been found to induce apoptosis of human colon cancer cells. Various extracts of kiwifruit have been found to have selective cytotoxic activity against human oral cancer cells.

Additional comments

Kiwifruit sold in the U.S. normally has green flesh when ripe. However, there exist some cultivars with red pigments in the flesh, and these are likely to contain more cancer-fighting anthocyanins and carotenoids than regular kiwifruit.

Kiwi should not be consumed with warfarin (Coumadin) or other blood thinners since it contains a natural blood thinner.

THE GRAPEFRUIT DIET IS ALIVE AND WELL AND WORKS...


I don't know about you folks, but I carry a bit of middle age weight that is difficult to get rid of. I was listening to a talkback radio program just last night, and a caller there praised the virtues of the humble grapefruit. It brought back memories of a popular diet of a quarter of a century ago - the grapefruit diet. So off to Google I went!

A new study by Nutrition and Metabolic Research Centre researchers at Scripps Clinic has confirmed that a simple act of adding grapefruit to your diet can result in real weight loss.

The grapefruit diet is not a myth. No, it is actually something an older generation knew 25 years or so ago. Grapefruit has a high fibre content and low glycemic load, and is a not so secret weight loss weapon. I didn't have a weight problem back then; I was a smoker and that was responsible for controlling my weight. Since then I have successfully given up smoking...and suffered the major side affect of giving up smoking - weight gain. Its all to do with a change in your metabolism.

The advice given last night has me seriously considering adding grapefruit to my diet - basically eating half a grapefruit or drinking grapefruit juice with every meal.It apparently takes a couple of weeks before weight loss becomes evident.

Diet tips for men only...

Diet tips for men only...


Diet tips for men only

When we say that men and women are different, we're not telling you anything you didn't know already.

But what many of us don't realise is that men and women are different when it comes to losing weight, as well as in more obvious ways.

Our bodies have different needs and our minds have different motivations. Which means that if you want to lose weight sensibly, you can't just piggyback onto your girlfriend's diet plan and expect it to work.

"Men and women are totally different when it comes to weight loss — different body issues, different hormonal issues, different psychological issues," says nutrition consultant Kate Arnold.

"And the image of dieting — that it's all down to cottage cheese and a lettuce leaf - is really quite girly and not attractive to men."

With that in mind, we've gathered together a few handy hints on how to diet like a man, so you can lose the love handles without losing the will to live.

The basics
In some ways, of course, we're exactly the same as women. Like them, most of us should be aiming for a Body Mass Index (BMI) of between 18.5 and 24.9.

But it's not quite that simple. Men tend to have a higher percentage of muscle than women, and if you're very well built the BMI number may describe you as overweight mistakenly.

So it's worth measuring your waist circumference too. Over 37 inches and you start to become more at risk of health problems; over 40 inches puts you in the high-risk category.

Get help
If you have a wife or girlfriend, make sure she knows you're looking to eat more healthily. Women can be very good weight loss companions.

"I've seen men's health turn around purely because the cooking was done by the female in the house and they had no options as to what to eat," says Arnold.

But she adds a proviso. This requires a strong, supportive and respectful relationship. If we feel bullied or henpecked most men will simply stop taking orders and march straight back to the beer and greasy food diet.

Mate weight
It's worth telling your mates that you want to lose weight, too, if only to hear some uncomfortable truths. Because when a woman announces her intention to diet her friends fall over themselves to tell her how little she needs to diet.

And when a man announces his intention to diet his friends fall over themselves to tell him how much he needs to diet — and spend the next hour laughing at his insipient moobs.

Which is both cruel and kind. It tells it how it is. And if, in the coming weeks and months, the man fails to present a leaner, trimmer figure, his mates will make sure he knows about that, too.

The beer and kebab diet
But mates who drag you to the pub can also be trouble. To lose weight, men need to reign in their weekend excesses to an extent few women do.

The hard truth is that beers are packed with more calories than the shorter drinks women prefer. Kate Arnold suggests you offer to be the Saturday night driver for a few months and stick to lime and soda.

If you must drink alcohol, single measures of spirits with low calorie mixers are the best choice.

The same advice goes for the post-pub takeaway. The healthiest option is not to have one at all, but if that's occasionally out of the question, go for a chicken skewer rather than kebab meat, a tomato-based dish rather than a creamy option, and boiled rice rather than fried.

Don't diet
But weekends aside, perhaps the most crucial diet tip for men is to, well, stop dieting. "Diets aren't sustainable long term," says Arnold. Evidence suggests men fall off diets more easily than women.

And don't be fooled into thinking that low-carb meat-fest diets like the Atkins are exactly what men need. Men are already at higher risk of heart disease than women, and diets packed with red meat, eggs, cheese, butter and fried food will be high in artery-clogging saturated fat.

Eat like a man
So what should you eat — day-to-day — to lose weight? Some of the advice crosses genders, of course. Eat more fruit and veg, less fried and processed foods, and watch your portion size.

After that, Kate Arnold believes that sensible eating is not the nightmare of self-sacrifice some men think it will be, and that men simply need to change their perception.

"For instance, fat is seen as bad, but tell men they can have a scrape of butter and grilled bacon on wholemeal toast and breakfast becomes a completely different ballgame," she says.

More generally, men should eat protein when hungry, rather than carbohydrates and sugar. Protein fills you up, especially on top of small portions of wholegrain carbs like whole-wheat pasta, brown rice and wholemeal bread.

Kate Arnold suggests an ordinary day's eating for men might include scrambled eggs on toast for breakfast, a jacket potato and tuna salad for lunch and salmon or grilled chicken with sauteed potatoes and steamed vegetables for supper. Nuts and fruit make great snacks.

Repeat that sort of regime often enough and you'll lose weight, feel healthier and gain energy. Given those benefits, it really doesn't seem like such a great sacrifice at al

Research shows smoking doubles the risk of getting dementia in old age...


Research from the US shows that smoking in middle age more than doubles the risk of alzheimers disease and other dementia later in life, according to one of the first long-term studies that have examined this issue.
Smoking definately has a clear effect on heart and lungs, but whether it also damaged the brain has been controversial. After looking at other factors that can contribute to dementia - such as race, age, diabetes, heart disease and substance abuse, the study published in the ARCHIVES OF INTERNAL MEDICINE recently found a significant link with heavy smoking at middle age.

Compared with non-smokers, those who smoked two packs a day or more had a 114 % increased risk of dementia (more than double), while those who smoked a half pack to one pack had a 37% increased risk. Middle aged former smokers did not appear to have an increased risk of later dementia
.
Researchers in Finland and Sweden followed 21,123 middle-aged members of a health plan who took part in a survey between 1978 and 1985
.
The subjects were then followed for an average of 23 years. Giving up smoking appeared to improve chances of avoiding increased chances of getting dementia in old age.
