Apple Health Benefits

To answer this question, researchers from the Australian CSIRO have been reviewing the growing body of research that applies to health benefits of apples and the role they play in human health. In this post I summarise the key findings for you.

General Information

Nutritional Analysis

Apples are highly nutritious and a great source of fiber.
The peel of an apple has very high concentrations of anti-oxidants, with higher levels of antioxidant capacity generally found in darker, redder coloured apples. So do not peel your apples.

Another point of interest – According to principal component analysis, the lighter the colour of an apple’s flesh, the more nutritious it is.

Storage of Apples

Keep your apples in the fridge instead of the fruit bowl in order to retain their antioxidants and have them stay crisp for longer.

Specific Health Benefits of Apples

Heart Disease

There is ever increasing evidence of the role of fruits and vegetables (specifically including apples) on protecting you from cardiovascular diseases, such as heart attack and stroke.

Cholesterol

Apples have been shown to have a cholesterol lowering effect. In one study the researchers found that eating three apples resulted in the reduction of the cholesterol level of about 5-8%.
Incidentally, the consumption of apple juice showed no such effect. So skip the juice and get the real thing – you know, an apple a day…

Weight Loss

Consuming whole fruits has been shown to produce a more positive effect on satiety than the same energy from juice or puree.
In fact, a study found that the energy level from fruits, independent of the firbe amount may reduce energy consumption and body weight over time.
Research further suggests that the polyphenols found in apples may regulate the fat metabolism in healthy people with relatively high body mass index (BMI).

Type 2 Diabetes

A large study of nearly 38,000 women over nine years found that women who were consuming one apple a day had a 28% reduction in their risk of type 2 diabetes, compared to women who consumed no apples.
Apples also have a low GI (Glycaemic Index), in the range of 28-44, which may be a contributing factor to the prevention of diabetes.

Allergy

You guessed it – apples have been linked to reducing the incidence of atopic dermatitis. The health benefits of apples include that they may alleviate some of the symptoms of respiratory allergy such as sneezing.

Asthma

Your good apples have been reported to be associated with lower incidence of asthma and bronchial hyperactivity.
In fact, a related study found that pregnant women who consume apples (and fish) may provide their unborn babies protection against developing childhood asthma and allergic diseases.

Health Benefits of Apples for Cancer

While the evidence for the role of fruit and vegetables in generally reducing cancer risk is not as strong as it once appeared, this does not rule out the significant potential for specific fruits and vegetables.
Laboratory cell-based studies have shown that apple peel extract possesses strong anti-proliferative effects against cancer cells. So, make sure you do not peel your apples.

There is particularly strong evidence for the consumption of apples in preventing mouth, oesophagus, lung and stomach cancers.

So in conclusion, an apple a day will not just keep your doctor away, but also a multitude of specialists, surgeons, drug companies and intensive care units. Please do yourself a favour and consider having an apple today, and every day following – because the health benefits of apples are too great to ignore.

Research by the Australian Bureau of Statistics reveals that since the late 1980’s life expectancy has increased by 6 years for men and 4 years for women, with men living until 79 while women until 83.7 years. This is good news indeed!  Unfortunately this does not mean we are healthier than previous generations!  Quite on the contrary, we are actually just sick for longer.  That was the message during the Australian Lifestyle Medicine Association Conference held in Sydney last month.
They say Australia is the lucky country.  However, the fact remains that despite a decade of unprecedented wealth, limitless choices, advanced healthcare, we are not as “well” as we should be.  We are staring down the barrel of a chronic disease crisis of unprecedented proportion.  Obesity, heart disease, stroke, type 2 diabetes and cancer are leading causes of preventable death.
To date, the health impact of overweight and obesity are yet to be experienced in this country.  Our current health infrastructure is ill-equipped to handle the fast rising “tsunami”.  So what should we do about this burgeoning problem?  The answer is not to have more doctors to meet the needs of a rapidly ailing population.  Instead, we have to take responsibility for our health.  The onus is on each of us to make sure we keep as healthy as possible by making life-enhancing lifestyle changes.
Did you know that during World War II, health improved in the general population in England?  This was because the English were forced to a basic daily diet of wholemeal bread, potatoes and home-grown vegetables.  Eggs, milk, butter, salt, sugar and meat were strictly rationed.  Food restrictions actually brought on unexpected health improvement!
During the Australian Lifestyle Medicine Conference, Professor Garry Egger echoed the same view when he spoke about the inverse relationship between the state of the economy and population health. He showed a graph depicting predictable improved state of health with each economic crisis over the last century.  It is ironic that improved economic conditions is consistent with bad health outcomes.  This is a clear sign that we are victims of excesses or “the good life”.
What do you think?  What active steps are you taking to improve your state of health?

NB: Professor Egger is also the Director, Centre for Health Promotion and Research, Sydney, and author of ‘Health, ‘ill-th’ and economic growth: Medicine, environment and economics at the cross-roads’, a soon-to-be published paper in the American Journal of Preventive Medicine.

Not all fatness indicates disease risk. Not all leanness indicates lack of disease risk. So what is the one factor that is a potent indicator of disease risk? It is an inflammatory process called metaflammation, para-flammation or smouldering inflammation. This condition appears to be inextricably linked with individual lifestyle behaviours like:

1. poor diet
2. inactivity
3. excessive exercise (modern endurance events)
4. inadequate sleep (due to deprivation, insomnia or sleep disorders like sleep apnoea)
5. mental states like anxiety or depression
6. environmental stressors
7. excessive alcohol
8. smoking

Markers of inflammation are expressed through a range of immune mediators such as cytokines, chemokines, adipokines, myokines and transcription factors. Recently, C-reactive protein has gained more attention than NFkB, TNF alpha and Il-6 but overall, these are common markers used to identify unhealthy inducers of metaflammation. It seems, the lifestyle-related inducers listed above are associated with oxidative stress, insulin resistance and eventual development of disease states.
Regularly consuming high glycaemic foods or large quantities of highly processed carbohydrate foods leads to inflammation and aging of cells. As Professor Jennie Brand Miller, world leading authority on the glycaemic index puts it very simply, “High GI foods lead to high inflammatory markers due to oxidative stress. What happens is that the high glucose load overwhelms the power-house (mitochondria) in the cell causing lots of free radicals to be generated. This leads to death of the mitochondria and eventual cell death.” In essence, aspire to eat like traditional natives and regularly choose low GI foods.
Regular moderate level physical activity, approximately ½ to 1 hour per day most days of the week is anti-inflammatory. Getting 8 hours of good quality sleep daily is also vital. It appears that the “stress-like’’ effects of sleep deprivation and the accompanying hormonal changes are associated with obesity.
In an advanced society like ours, mental states associated with stress, anxiety and depression seem to generate acute inflammatory responses accompanied by elevated levels of cytokines. Smoking also elicits a parallel reaction. Both of which are linked to degenerative diseases.
In a nutshell, the maintenance of a disease-free state lies squarely in our hands. Health is about consistently choosing pro-life behaviours through good nutrition, exercise, good quality sleep, relaxation and powerfully choosing joy-filled states. What are your views? Please post you comments below.

Foods containing pungent flavour are often rich in sulphur content. These foods not only are great mould deterrents, they also play vital roles in DNA repairs. Cruciferous vegetables like broccoli, garlic and onions are sulphur rich and powerful inducers of protective enzymes like superoxide dismutase and glutathione peroxidase. They are also high in indoles and can inhibit colorectal, bladder, lung, mouth, throat, stomach and breast cancers.

Cruciferous vegetable are particularly rich in isothiocynates.  Isothiocyanates have amazing anti-aging properties; this is because they are potent inhibitors of enzymes that promote glycation.  Glycation occurs when oxidation of sugars coating the surface of proteins like collagen result in the formation of Advanced Glycated Endproducts – AGEs. As the name implies, AGEs literally cause premature aging with the formation of saggy, wrinkly skin.  Note that any external signs of aging are accompanied by the aging of  internal organs as well.  The external and internal are never mutually exclusive. 

This aging process is even more pronounced in diabetics as AGEs form more quickly with elevated blood sugar levels.  It is not uncommon for a diabetic diagnosed at the age of 30 to have a physiological age of 75 by the time they reach the chronological age of 60.  It is a well-known fact that accelerated aging comes with poorly controlled blood sugar levels.  Hence, to reduce age-related cell damage, diabetics should tuck into large quantities of these vegetables to decelerate the glycation process and its accompanying premature aging.
In conclusion, these vegetables protect you from DNA damage, stimulate cancer cell death (cell apoptosis) and keep you looking and feeling young. Why would you not eat heaps more of them daily?

Australians are among the fattest people in the world. This has caused a host of chronic diseases to develop. A cluster of some of the above-mentioned conditions is commonly called metabolic syndrome. It is often said that obesity is harder to cure than cancer! For over 10 years, it has been known that obesity is directly associated with inflammation.

More and more experts are seeing body weight or fat as potential ‘markers’ of other health problems, like cancer, heart disease and diabetes. Low grade form of inflammation commonly called metaflammation seems to result from certain lifestyle behaviours. Some of these behaviours are responsible for making us fat.

Certain food choices and lack of activity are now known to contribute notoriously to ‘metaflammation’. According to studies, merely changing or reducing weight without adopting all aspects of lifestyle changes aimed at reducing inflammation are doomed to fail in the long run. To achieve better overall health outcomes, all aspects of lifestyle that contribute to reducing inflammation should be adopted.
Sleep is a factor that is largely neglected in our modern society. We now know that less than 7 hours sleep a day has been shown to raise inflammatory makers. This is related to psychological stress which has been known to cause pro-inflammatory responses. Chronic stress causes a chronic rise in stress-related hormones like cortisol and the concurrent reduction in the ‘feel-good’ hormones – endorphins. Chronic stress and depression are directly associated with metaflammation. Metaflammation leads to numerous disease states as a result of insulin resistance! In other words, science has shown that you can sleep yourself and relax yourself slim! Wow, how awesome is that? If you did nothing else but get good quality sleep and adopt deep relaxation, you could be a few kilograms lighter than you are now! How is that for good news?

Hence the winning formula for keeping trim involves a complete lifestyle overhaul combining:
1. Good sleep
2. Stress management (so you have little or no stress in your life)
3. Plenty of exercise – take every opportunity to move!
4. Good solid ‘anti-inflammatory’ diet filled with back-to-basics ‘earth foods’
5. No smoking

All of these health-enhancing factors have not changed since the time of Hippocrates. How remarkable is that? These 5 simple factors make up the entire prevention armoury. They say the more things change the more they stay the same, this must be one of those things!

In this article, we look more closely at the benefits of Shiitake mushrooms and how to prepare them in a quick and tasty stir-fry.

Mushrooms are often regarded as vegetables but they are really a fungus. Shiitake mushrooms have been used medicinally by the Chinese for over 5,000 years. They are commonly known as the ‘symbol of longevity’ in Asia because of their health promoting properties.

Shiitakes’ legendary benefits can be attributed to an active compound called lentinan. Lentinan appears to confer healing benefits that boost the immune system and strengthen its ability to fight infection by reducing inflammation. Lentinan is a polysaccharide which is also known as branched chain beta-glucan. Branched chain beta-glucan has also been demonstrated to confer anti-cancer activity particularly in gastric cancer, stimulating cancer cell apoptosis.
Another active compound called eritadenine is also found in shiitake. This compound appears to lower cholesterol levels by up to 12% when consumed regularly.
A powerful antioxidant has been discovered in mushrooms, it is L-ergothioneine. In 2005, the American Chemical Society meeting in Washington, D.C., revealed that mushrooms contain higher concentrations L-ergothioneine than chicken liver and wheat germ (two food items previously erroneously nominated as highest in this antioxidant). The shiitake may contain up to 13 mg of ergothioneine in a 3-ounce serving. This is almost forty times as much as that found in wheat germ. What is even more wonderful is that L-ergothioneine is not destroyed with cooking!

Stir-fried Shiitake and Asparagus Recipe

Ingredients

• Garlic, 8 cloves, chopped
• Asparagus, 3 bunches, cut into 15cm pieces
• Shiitake, 2 trays, quartered
• Water
• Chicken stock powder, 1.5 teaspoon

Preparation
Fry chopped garlic; add asparagus and then shiitake followed by some water. Lastly add 1.5 teaspoon of chicken stock powder.

Couscous Salad

In 2001, an anticancer drug hailed ‘a miracle’ was approved by the Food and Drug Administration Department (FDA). This drug is called Gleevec.

Gleevec seems to be able to arrest the formation of new blood vessels (angiogenesis) needed for cancer cell growth. Did you know that herbs and spices rich in fatty acids of the terpene family also act along the same lines as Gleevec?
Terpenes seem to stimulate cancer cell death (apoptosis) thereby limiting cancer cell growth, containing tumours. Armed with this knowledge, lets look at preparing a dish that is low in glycaemic index and rich in herbs.

The following recipe is prepared with couscous as the principal ingredient. Couscous has a glycaemic index of 61 and glycaemic load of 8.7. The glycaemic index of a food item measures how it affects your blood glucose level (low glycaemic index <55, 56<moderate glycaemic index<69, high glycaemic index >70). You can think of this as a number which represents the glycaemic/glucose ‘potency’.
In this instant, couscous is considered a moderately high glycaemic index food. Adding lemon and lime to couscous will reduce the glycaemic index of the meal as the acidity of these citrus will reduce the rate at which food goes into the small intestine from the stomach, thus lowering the rate of rise of blood sugar level even more. Achieving a flatter blood sugar response long term is the mainstay for management of insulin resistance. Studies have shown that frequently choosing low glycaemic index and glycaemic load food items in one’s diet will enhance insulin sensitivity and even prevent some cancers (preliminary studies seem to indicate that high insulin levels are associated with some tumours)!
Turmeric has powerful anti-inflammatory properties. Its absorption increases a thousand fold by adding olive oil and pepper in the recipe. The following is a low glycaemic index, ‘anti-inflammatory’ and terpene- rich meal. Enjoy!

Ingredients

Couscous, 1cup
Cherry tomatoes, ½ punnet
Chickpeas, 1cup (soaked, boiled and drained)
Cold pressed olive oil, 1 tablespoon
Mint, ½ a bunch
Parsley, ½ a bunch
Coriander, ½ a bunch
Lemon, ½ whole
Lime, ½ whole
Sugar, 1 teaspoon
Turmeric, 1 teaspoon
Water
Pepper
Chicken stock

Preparation

Put couscous in a bowl, pour boiling water and then add chicken stock and turmeric and set aside for 10 minutes. When liquid has been absorbed, separate couscous grains with a folk.
Add chick peas, tomatoes, mint, parsley, coriander, lemon, lime, sugar, pepper and cold pressed olive oil. Mix well and serve.

It is not uncommon for Japanese to use mushrooms as an adjunct to chemotherapy in cancer treatment with measurable positive outcomes. The rate of stomach cancer is 50% lower among Japanese who consume large amounts of mushrooms. Researchers in Kyushu University have shown that colon cancer patients given mushrooms with chemotherapy live longer.
