Jul 3, Belly Fat And Lifespan

Thu, 03 Jul 2008 17:12:22 GMT

Belly fat, also called abdominal or visceral adipose tissue, is associated with many aging health problems including metabolic syndrome.

A new animal study compared animals on a regular diet where they were allowed as much food as they wanted; animals on a calorie restricted, optimal nutrition diet; and animals who had their belly fat surgically removed and then were allowed as much food as they wanted.

As expected, the calorie restricted animals had the greatest mean and maximum lifespan.

While removal of the belly fat only increased maximum lifespan slightly, there was significant increase in mean lifespan compared to the regular diet animals (Muzumdar R, Visceral adipose tissue modulates mammalian longevity, Aging Cell, June 2008.

Both green tea, and certain diets have shown improvements in belly fat, while at the same time providing low calorie selections for calorie control.

Jul 2, Tea Extracts Help Radiation Damaged Skin

Wed, 02 Jul 2008 14:06:09 GMT

One of the side effects of radiation used to treat cancer patients is skin toxicity. A slow recovery from this skin damage can delay future treatments, increasing the risk to the cancer patient.

A study tested the application of inexpensive green tea extract on head and neck cancer patients being treated by radiation. The tea extract helped shorten the skin toxicity recovery period by 5 to 10 days.

The tea extract application tests showed that tea was effective by inhibiting inflammatory chemical pathways rather than antioxidant action. Green tea was more effective than black tea extract for many patients (Pajonk F, The effects of tea extracts on proinflammatory signaling, BMC Medicine, December 2006).

Jun 30, Safer Produce

Mon, 30 Jun 2008 20:26:02 GMT

Commercially available produce can be contaminated with disease-causing bacteria like Salmonella or E. coli, then distributed widely.

One way to help clean produce is commercial washing. Food plants frequently use flume water washing, but this method can make controlling bacteria difficult.

A new study shows that the addition of chlorine dioxide to flume water kills only 90 of the disease-causing bacteria.

In contrast, a commercially available produce wash (FIT) containing natural ingredients like grapefruit extract and citric acid, kills 99.9999 of the bacteria in flume water almost instantaneously.

Out of a million bacteria, chlorine dioxide would leave 100,000 alive while FIT leaves only 1 alive.

In addition, FIT does not have the same risk for plant workers as chlorine (Park et al, Efficacy of FIT produce wash and chlorine dioxide on pathogen control in fresh potatoes. Journal of Food Science, June 2008).

Many liquid soaps with grapefruit extract and citric acid are available for home use from your local health food store.

Jun 29, New Test For Early Detection Of Ovarian Cancer

Sun, 29 Jun 2008 17:39:09 GMT

Currently 75 of women are not diagnosed with ovarian cancer until they are in the later stages. By that time, it has become difficult to treat and more women die.

New research has found that combining a simple four-question screening questionnaire with the CA 125 ovarian cancer blood test can increase early detection to 80 and later stage ovarian cancer to 95.

These early detection rates are approximately 30 higher than each procedure (questionnaire and blood test) used separately (Andersen MR, Fred Hutchison Cancer Research Center, Cancer online, June 2008).

Early detection of cancers is the most powerful way to increase the efficacy of treatments. For more information about cancer screening, please consult with your personal physician.

Jun 28, High Fat Meals Unhealthy For Young Adults

Sat, 28 Jun 2008 22:44:18 GMT

Another study found that eating just one high-fat meal caused young adults to have markedly increased blood pressure when stressed.

Young adults ate a high-fat meal (42 grams fat) or a very low-fat meal (1 gram fat) with the same number of calories.

When additional stress was applied (e.g. putting the elbow into cold water), those who had eaten the high fat meal had higher systolic and diastolic blood pressure, as well as increased peripheral vascular resistance (Jakulj F, A high-fat meal increases cardiovascular reactivity to psychological stress in healthy young adults, Journal of Nutrition, April 2007).

A chronic high-fat diet is associated with a wide variety of health problems, including high blood pressure, heart attack, stroke, cancers, obesity, and others.

Jun 27, High Fat Meals Unhealthy For Older Adults

Fri, 27 Jun 2008 19:40:48 GMT

A new study found that eating just one high-fat meal caused memory loss.

Researchers tested adults over the age of 50 years who also had type 2 diabetes.

During the study, they were tested with three different meals: a high-fat meal of danish pastry, cheese, and yogurt with whipped cream; the same high-fat meal with added antioxidants (1000 mg Vitamin C plus 800 IU Vitamin E); and a meal of water only.

After eating, they were tested for word and paragraph memory recall.

There was consistently significant memory loss after eating the high-fat meal. Memory performance was similar with the water-only meal and the high-fat meal with added antioxidants of Vitamin C and Vitamin E (Chui MH, Baycrest Centre for Geriatric Care, June 2008).

More research is needed to learn if only oxidative stress pathways were involved and if other stronger antioxidants like EGCG would provide stronger protection.

Jun 26, Not 42?

Thu, 26 Jun 2008 15:04:44 GMT

According the The Hitchhiker's Guide To The Galaxy, the answer is 42.

However, new research has discovered that half the answer is 143.

Chemists from Ohio have analyzed the scaffolding from 24 million organic compound molecules known to exist.

They found that 12 million of them had molecular shapes that could be described by just 143 structural frameworks.

They also found that a top heavy "power law" was associated with the minimized shapes. In other words, a small number of successful shapes appeared in a large number of compounds.

By identifying successful shapes researchers hope to reduce the labor involved in developing new chemical products (Lipkus AH, Structural Diversity of Organic Chemistry. A Scaffold Analysis of the CAS Registry, Journal Of Organic Chemistry, June 2008).

This message was brought to you by oceans that still have fish.

O.K., Douglas Adams, you're right..."A cup of tea would restore my normality."

Jun 24, Green Tea Powder Storage

Tue, 24 Jun 2008 17:20:00 GMT

A new study tested the impact of humidity and added chemicals during storage of dry green tea powder.

During a three month storage test, they found that catechin (including EGCG, or epigallocatechin gallate, as well as epicatechin, epicatechin gallate, and epigallocatechin) stability could be maintained at 43 relative humidity at 22 degrees C for three months, despite caking.

Higher humidity caused chemical degradation.

The addition of sucrose, citric acid, and ascorbic acid to green tea powder during storage also significantly increased catechin degradation (Ortiz J, Interaction of environmental moisture with powdered green tea formulations: effect on catechin chemical stability, Journal of Agricultural and Food Chemistry, June 2008).

Green tea catechins are the primary antioxidants associated with risk reduction for many health conditions. They are very reactive chemicals, leading to their health benefits, but also making them fragile.

People using green tea powder such as matcha should buy amounts that they can use within a few months after opening.

People buying powdered green iced tea mixes may want to avoid those with sucrose, citric acid, or ascorbic acid if they want to be more certain of antioxidant stability.

Or make their own green iced tea from freshly brewed green tea.

Jun 24, Long Life, Exercise, And Calories

Tue, 24 Jun 2008 02:53:27 GMT

Regular exercise is necessary to maintain quality of life and can increase the average life span.

But only an anti-aging diet of calorie restriction with optimal nutrition increases the maximum life span.

Now a new study compares sedentary, treadmill exercised, and calorie restricted animals.

After 24 weeks, the sedentary mice who ate as much as they wanted were the fattest. Exercised mice had higher heat shock protein levels, but did not accumulate DNA damage from the oxidative stress.

The lowest levels of insulin and IGF-1 were only found in the 18 calorie restricted mice, leading the researchers to conclude that exercise may not be able to create the same hormonal and metabolic response that calorie restriction creates in the body (Huffman DM, Effect of exercise and calorie restriction on biomarkers of aging in mice, American Journal of Physiology, Regulatory, Integrative, and Comparative Physiology, May 2008).

Jun 22, Green Tea, Vitamin E, And Vitamin C

Sun, 22 Jun 2008 16:31:33 GMT

A new study has explored mixing green tea polyphenol antioxidants with Vitamin E and Vitamin C.

Researchers tested the antioxidant strength of EGCG, or epigallocatechin gallate, as well as EC or epicatechin, EGC or epigallocatechin, ECG or epicatechin gallate, and GA or gallic acid, all from green tea, with alpha-tocopherol (Vitamin E) and ascorbic acid (Vitamin C) against lipid peroxidation or free radical damage to fats (linoleic acid).

Results showed that the green tea polyphenols, Vitamin E, and Vitamin C could work synergistically to prevent peroxidation damage to fats.

Further study showed that the synergy was due to enhanced molecular regeneration.

Vitamin C helped regenerate green tea polyphenols and green tea polyphenols helped regenerate Vitamin E (Dai F, Antioxidant synergism of green tea polyphenols with alpha-tocopherol and l-ascorbic acid in SDS micelles, Biochemie, May 2008).

Jun 21, More news about Salmonella

Sat, 21 Jun 2008 17:55:27 GMT

The recent Salmonella outbreak in the United States has been traced to contaminated tomatoes. It has infected over 550 people in more than 30 states.

One of the ways Salmonella causes food poisoning is by using proteins to invade the cellular walls of the stomach and intestines. However, once this happens, our immune systems begin fighting the bacteria.

Now researchers have found a new protein in Salmonella called AvrA that stabilizes our intestinal cell wall and avoids alerting the immune system (Liao AP, Salmonella type III effector AvrA stabilizes cell tight junctions to inhibit inflammation in intestinal epithelial cells. PLoS ONE, June 2008). This allows the bacteria to increase in numbers safely for a longer time, leaving us with a larger, more dangerous infection to fight.

There are many ways to protect ourselves from Salmonella infection, with good sanitation practices at every level from farm to dinner table.

Here's some additional ways that green tea could help fight Salmonella infections.

Jun 16, Happy 100th, Teabags

Mon, 16 Jun 2008 15:54:55 GMT

In June 1908, a New York merchant, John Sullivan, sent out tea samples in silk sachets to his retailers. He was trying to save money and avoid sending larger amounts of loose leaf tea.

But he didn't include instructions to open the sachet and put the tea directly into hot water. So people dunked the whole "teabag" and they loved it.

An inexpensive gauze was quickly introduced and by 1930, a sealed paper fiber bag was being used. The paper basically served as an inexpensive infuser. The Americans loved the idea.

While people complained of lost flavor and low quality tea dust, others promoted the convenience.

As the 20th century began to speed up, convenience won, and teabags are now available everywhere.

The British waited a few generations to accept the tea bag, but Tetley Tea now sells over 200 million teabags a week using perforated paper.

Tea bags come in square, round, pyramid, and flow-through shapes to enhance extraction, and with whole leaf tea as well as tea dust for better flavor. You can even buy reuseable tea bags to make your own.

While tea bags will never replace the experience of sitting down with a pot of fresh whole leaf green tea, they can't be beat for traveling or a quick cup of tea to get you through a busy day.

Look for these green teas to try in a teabag or loose leaf.

Jun 13, Women And AIDS

Fri, 13 Jun 2008 16:40:50 GMT

As of 2007, 62 of all people living with HIV are women or adolescent girls, according to the United Nations.

Many social habits have promoted this high rate of infection, including:

illiterate and uneducated women (if women and girls acquire knowledge of sexually transmitted diseases, they are accused of promiscuity)

poverty (women may be forced into sex work to stay alive, sold as child prostitutes, or be forced to stay with their husbands in spite of high risk behavior on his part)

marriage customs including polygamy or older men with child brides (older men are more likely to be sexually experienced and possibly exposed to STDs than young girls>

violence (women and girls are more often victims of sexual violence and rape which increases the risk of STDs)

These factors have led to a dramatic increase in female HIV infections, not only in Africa, but also Latin America, Asia, and Eastern Europe. In the United States, AIDS is the leading cause of death for African-American women age 25-34.

Global efforts include women's education, economic choices, and equal access to treatment.

Without this action, the infection rates will only get worse.

Here's research on HIV prevention

Tea Chemicals Reduce Lung Cancer In Smokers

Wed, 11 Jun 2008 17:39:00 GMT

Smoking and second-hand smoke significantly increase the risk of lung cancer. The Center for Disease Control states that 90 of lung cancer deaths in men and 80 of lung cancer deaths in women of the United States are due to smoking.

While the best prevention is to stop smoking, now a new study has shown that a high intake of flavonoid chemicals found in tea, fruits, and vegetables also substantially reduces the risk of lung cancer in smokers.

In a case-control study of 558 lung cancer patients and 837 controls in Los Angeles, California, researchers analyzed dietary intake.

After adjusting for other influences, they found that higher consumption of flavonoid catechins, epicatechins, quercetins, and kaempferols reduced the risk of lung cancer in smokers from 32 to 56. Other flavonoids including thearubigins, hesperetin, naringenin, and myricetin showed no association.

Catechins and epicatechins are high in green tea, while quercetin and kaempferol are found in apples, onions, Brussels sprouts, and beans.

The scientists plan more studies to determine optimal intake of these flavonoids (Cui Y, Dietary flavonoid intake and lung cancer--a population-based case-control study, Cancer, May 2008).

According to a story in the Washington Post June 2 (also referring to the New York Times), Barak Obama, the Democratic candidate for the U.S. presidency in 2008, drinks green tea.

In fact, Obama loves green tea so much that his staff has been known to clean out stores of his favorite flavors during his primary campaign.

What's his favorite?

According to reports, he loves bottled green tea made by Honest Tea, a Maryland company specializing in organic tea.

His favorite used to be Community Green Tea. Then it was Green Dragon Tea. Now he's drinking Black Forest Berry.

Since the tea was hard to find everywhere in the U.S., the company owner has sold 40 of the company to Coca-Cola to assure distribution.

Green tea...a winner for 5000 years.

I always fear that creation will expire before Tea-time.

Rev. Sydney Smith

While there's tea, there's hope.

Sir Arthur Pinero

(described himself as) a hardened and shameless tea drinker, who has for twenty years diluted his meals only with the infusion of this fascinating plant; whose kettle has scarcely time to cool; who with tea amuses the evening, with tea solaces the midnight, and with tea welcomes the evening.

Samuel Johnson (famous for the first English Dictionary and drinking 40 "saucers" of tea a day)

The first bowl sleekly moistened throat and lips. The second banished all my loneliness. The third expelled the dullness from my mind, sharpening inspiration gained from all the books I've read. The fourth brought forth light perspiration, dispersing a lifetimes troubles through my pores. The fifth bowl cleansed every atom of my being. The sixth has made me kin to the Immortals. The seventh... I can take no more.

Jun 3, Tomato Powder For Prostate Cancer

Tue, 03 Jun 2008 16:45:01 GMT

A new study has shown remarkable prevention of prostate cancer with enhanced tomato powder.

Animals given chemically-induced prostate cancer survived for 40 weeks. If they were given plain dehydrated tomato powder in their food, they survived for 50 weeks. And, if they were given tomato powder enhanced with FruHis, they survived 51 weeks.

FruHis is a fructose-histidine ketosamine compound from many dried fruits and vegetables that has metal chelating and antioxidant properties.

Only 10 of the tomato powder plus FruHis animals had prostate cancer tumors on autopsy. 30 of the tomato powder animals had tumors and 60 of the control animals had tumors.

Further evaluation has shown that FurHis and lycopene (from tomatos) together prevent 98 of prostate cancer cell growth (Mossine V, Interaction of Tomato Lycopene and Ketosamine against Rat Prostate Tumorigenesis, Cancer Research, June 2008).

Green tea shows 91 prevention of prostate cancer

Jun 1, Mesothelioma And Chemotherapy

Sun, 01 Jun 2008 16:22:42 GMT

Mesothelioma is a malignant cancer almost always caused by asbestos exposure.

This cancer, once diagnosed, is rapidly fatal in spite of current therapies.

A new study from the UK examined three different therapies with mesothelioma patients.

Researchers divided 409 patients with malignant pleural mesothelioma into three groups in a highly controlled study with consent.

One group of patients received active symptom control which could include steroids, pain-killing drugs, bronchodilators, and radiation. A second group received the same symptom controls with the addition of chemotherapy. A third group received the same symptom controls with an injection of vinorelbine weekly for 12 weeks.

Average survival after diagnosis was 7.6 months for active symptom control only, 8.5 months for symptom control plus chemotherapy, and 9.5 months for symptom control plus vinorelbine. These differences were not statistically significant.

There were also no significant differences in quality of life as defined by activity levels, pain, breathing difficulty, or general health.

The authors conclude that chemotherapy did not offer significant improvement of mesothelioma regarding survival time or quality of life, but the addition of vinorelbine deserves further research (Muers MF, Active symptom control with or without chemotherapy in the treatment of patients with malignant pleural mesothelioma (MS01): a multicentre randomised trial, Lancet, May 2008).

Have you been exposed to asbestos at work, at home, or in your community?

May 31, How Long Have You Taken HRT?

Sat, 31 May 2008 18:27:36 GMT

Research shows that hormone replacement therapy (HRT) increases breast cancer risk.

A new study of 3464 women with breast cancer compared to 6657 matched controls found almost double the risk of breast cancer while women were taking HRT.

Estrogen-only HRT only raised the risk slightly while progesterone-estrogen combinations were associated with the greatest risk of breast cancer.

When women stopped taking HRT, their risk of breast cancer returned to normal after five years (Flesch-Janys D, Risk of different histological types of postmenopausal breast cancer by type and regimen of menopausal hormone therapy, International Journal of Cancer, May 2008).

This research confirms the US and UK studies, Women's Health Initiative and Million Women Study.

What's the breast cancer survival rate?

Can green tea help prevent breast cancer recurrence?

May 29, The Return Of Leptin

Thu, 29 May 2008 18:24:18 GMT

Leptin is a hormone that helps govern appetite in the brain.

When it was first discovered, many hoped that normalizing leptin would solve the problem of overeating and overweight.

But overweight people and animals proved to be resistant to any benefit from leptin.

Now a new preliminary study has found that moderate exercise overcomes the resistance to leptin in overweight animals and prevents obesity.

Animals were raised on either a standard or high-fat diet. Then they were given leptin and separated into an exercise group and controls.

With animals on a standard diet, both leptin and exercise reduced any weight gain and the effects were additive.

With a high-fat diet, leptin briefly reduced weight gain, but then immediately doubled the weight gain.

But when these high-fat diet animals were allowed to exercise at the same time, all weight gain was prevented (Shapiro A, Synergy between leptin therapy and a seemingly negligible amount of voluntary wheel running prevents progression of dietary obesity in leptin-resistant rats, Diabetes, March 2008).

Currently, researchers are considering too much leptin to be a cause of obesity rather than a cure. Now it be turn out to be beneficial as long as people exercise.

Other research shows the benefits of synergy. For example, EGCG from green tea and ibuprofen together were almost four times more powerful against prostate cancer cells than alone. And diet and exercise alone showed no effects on breast cancer recurrence, but together showed 50 less recurrence.

On the other hand, sometimes synergy can be negative. A study showed that taking ibuprofen eliminated any benefit from aspirin in preventing strokes.

Here's more benefits from exercise

May 28, Green Tea Reduces Damage To Older Brains

Wed, 28 May 2008 16:42:30 GMT

Aging brains show reduced capacity to protect brain tissue against free radical (oxidative stress) damage, tissue atrophy or shrinkage, and subsequent loss of memory and learning capacity.

Now several studies show that green tea catechin antioxidants can reduce this damage to the brain.

One of the brain's antioxidant enzymes is glutathione peroxidase which is reduced with age. Green tea catechins protected glutathione peroxidase levels and activity in age-acccelerated animals compared to untreated animals (Kishido T, Decline in glutathione peroxidase activity is a reason for brain senescence: consumption of green tea catechin prevents the decline in its activity and protein oxidative damage in ageing mouse brain, Biogerontology, August 2007).

Another report found that daily green tea for 14 months prevented memory loss and DNA oxidative damage to age-accelerated animals (Unno K, Daily consumption of green tea catechin delays memory regression in aged mice, Biogerontology, April 2007).

An earlier study showed that long-term usage of daily green tea catechins showed reduced damage to DNA from oxidation, protection against atrophy in the brain, and protection of learning capacity and working memory (Unno K, Suppressive effect of green tea catechins on morphologic and functional regression of the brain in aged mice with accelerated senescence (SAMP10), Experimental Gerontology, July 2004).

These improvements in brain structure, physiology, and function in aged animals were all achieved with daily green tea for most of their lives.
