Lutein Increases Skin Hydration and Elasticity

Lutein, a carotenoid known to be involved in eye health, has been found to also play a role in skin health.

Results indicated that oral lutein supplementation increased skin hydration by 38 percent, skin elasticity by 8 percent, and the level of superficial lipids by 33 percent compared to placebo. Lutein also decreased oxidation of lipids by 55 percent, indicating it could help the lipids in skin from deteriorating due to free radical damage. Volunteers who received both oral and topical lutein experienced a 60 percent increase in hydration, a 20 percent increase in elasticity and a 50 percent increase in skin lipids.

Curcumin Helps Lower Cholesterol Levels

One health-promoting property of curcumin gaining attention is its ability to help lower cholesterol within the normal range. Unfortunately, the mechanisms behind curcumin’s health benefits, including that of lowering cholesterol, are still unclear. This study may have found a possible mechanism on just how curcumin lowers cholesterol within the normal range.

The researchers found that treatment with 4 mg of curcumin (10 micromoles) caused an up to sevenfold increase in LDL-receptor mRNA while also causing a significant activation of both LXR and RXR genes, all of which cause a decrease in cholesterol synthesis.

The researchers concluded, “curcumin caused changes in gene expression in HepG2 cells that are consistent with the [cholesterol-lowering] effects of dietary curcumin.”

Omega-3 Fatty Acids Reduce Incidence of AMD

In a study published in 2006 Archives of Opthalmology, 2335 elderly patients were screened for dry (early) and wet (late) age-related macular degeneration (AMD) (maculopathy).

The screening showed that low fat diets (less than 27% calories from fat) increased the likelihood of early ARM by 50-70%. A low omega-3 unsaturated fat diet also slightly increased the likelihood of both dry and wet ARM. Diets high in omega-3 unsaturated fats decreased the incidence of wet ARM by 60%.

Researchers concluded that consuming three or more fish meals per week may help keep elderly eyes healthy. Alternatively, fish oil supplements are available. There are a number of good fish oils on the market, but one of the best new ways to get omega-3 polyunsaturated fats is from krill oil.

Omega-3 Fatty Acids Plus Exercise Reduce Body Fat

Participants were assigned to either daily supplementation with vegetable oil with or without an exercise regimen or daily fish oil supplementation (providing 2 grams of DHA/EPA omega-3 fatty acids) with or without exercise.

Body compositions revealed that the only group to exhibit a significant reduction in percent body fat was that combining exercise with fish oil supplementation. This improvement appeared to reflect an enhanced fat oxidation during exercise.

This research indicates the potential for fish oil supplementation to enhance the efficacy of exercise programs in overweight subjects. There are a number of good fish oils on the market, but one of the best new ways to get omega-3 polyunsaturated fats is from krill oil.

Omega-3 Fatty Acids Reduce Arrhythmia 75%

Sudden cardiac death is any death from cardiac causes within one hour of the onset of symptoms. It is almost always due to arrhythmias known as ventricular tachycardia or ventricular fibrillation.

Patients with heart disease either received an omega-3 fish oil supplement each day for at least four weeks while others served as controls. All patients were subjected to arrhythmia testing by electrical impulses to induce sustained ventricular arrhythmias.

After fish oil supplementation, 75% of the patients were either no longer inducible or required extra stimulation to induce the arrhythmia as compared to only 14% in the control group.

Omega-3 Fatty Acids Reduce Progression of AMD

Higher dietary DHA/EPA Omega-3 Fatty Acids associated with lessened progression in age-related vision loss.

In this study, called the Age-Related Eye Disease Study (AREDS), participants who had early or intermediate age-related macular degeneration in at least one eye at entry were followed up for 8 years. During follow-up, Dr. San Giovanni reported that people with the highest levels of dietary DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) were less likely by 20% and 25%, respectively, to progress to visual loss.

There are a number of good fish oils on the market, but one of the best new ways to get omega-3 polyunsaturated fats is from krill oil.

Vitamin D Cuts Pancreatic Cancer Risk by 43%

Consumption of Vitamin D tablets was found to cut the risk of pancreatic cancer nearly in half, according to a study led by researchers at Northwestern and Harvard Universities.

The study examined data from two large, long-term health surveys and found that taking the U.S. Recommended Daily Allowance of Vitamin D (400 IU/day) reduced the risk of pancreatic cancer by 43 percent. By comparison, those who consumed less than 150 IUs per day experienced a 22 percent reduced risk of cancer. Increased consumption of the vitamin beyond 400 IUs per day resulted in no significant increased benefit.

A number of new studies have led researchers to recommend increasing the vitamin D RDA to 1,000 to 2,000 IU/day.

Green Tea Extract Slows the Progression of Huntington’s Disease

A new study indicates that the green tea polyphenol, epigallocatechin gallate (EGCG), may slow the build up of proteins that are implicated in Huntington’s disease and may slow the motor function decline that occurs in Huntington’s patients.

Once the disease has developed it is incurable, so stopping the buildup of damaging proteins as well as stopping the proteins from misfolding could slow or prevent the development of the disease.

The study authors discovered that the green tea extract could strongly interfere with the early events leading up to the buildup of mutant proteins in a dose-dependent manner.

Omega-3 Fatty Acids Prevent More Deaths than Defibrillators

Omega-3 fatty acids may prevent more sudden deaths than automated external defibrillators in homes and public places or implanted defibrillators, according to the results of a new study.

Raising blood levels of omega-3 fatty acids in individuals after a cardiac event such as a heart attack could save 58 lives a year in this simulated city of 100,000 people, according to the simulation’s predictions. Only seven lives per year were saved by automated external defibrillators, while implantable defibrillators prevented 30 deaths each year. Projected to the US population of 300 million people, eating omega-3 fatty acids would save 174,000 lives per year. Another perspective, nearly 3,000 people perished in the 9/11 attack. What is it worth to encourage people to consume omega-3 fatty acids to save 174,000 American lives per year?

Omega-3 Fatty Acids Protect Skin Against Sun Damage

A review study by researchers at Baylor College of Medicine indicates that omega-3 fatty acids can protect the skin from the inflammatory response caused after sun exposure and that these fish-derived nutrients can reduce the risk of non-melanoma skin cancer.

Omega-3 fatty acids inhibit the cancerous changes that occur after ultraviolet radiation, including decreasing tumor growth and reducing tumors’ ability to multiply. However, equivalent levels of omega-6 fatty acids increase the cancerous changes that occur after exposure to ultraviolet radiation. Omega-6 fatty acids are found in margarine, vegetable oils such as corn oil, safflower oil, and salad dressing. The richest sources of omega-3 are fish oil and krill oil.

CoenzymeQ10 Improves Cardiovascular Functional Capacity

The results of a Coenzyme Q10 (Q-absorb™ brand), an enhanced-absorption CoQ10 formula, study on chronic heart failure patients was published in the September 2006 European Heart Journal.

Scientists measured the effects of 300 mg per day (100 mg T.I.D.) CoQ10 Q-absorb™ on the cardiovascular functional capacity of 23 heart patients. Results were an improved functional capacity (peak volume of oxygen consumed VO2), improvement in endothelial-dependent vasodilation, and tripling of plasma coenzyme Q 10 levels.

Pine Bark Extract Speeds Up Diabetic Ulcer Healing

A daily supplement of the French maritime park bark extract, Pycnogenol, could speed up the healing of diabetic foot ulcers by 75 per cent, says a new Italian-German study.

At the end of the study the researchers found that patients supplemented with oral and topical pine bark extract experienced a 74.4 per cent decrease in leg ulcer size. Groups taking either oral or topical pine bark extract experienced a 41.3 and 33 per cent decrease in ulcer size, while the control group's ulcers decreased by only 22 per cent. No adverse effects were reported, said the researchers.

Omega-3 Index Proposed for Cardiovascular Health

Another scientific review has concluded that omega-3 fatty acids are beneficial to heart health, and proposes a new measure of cardiovascular risk called the “omega-3 index”. The measure, merely a quantification of the fatty acid status of a person, similar to the measurement of cholesterol, could help physicians and heart patients achieve levels of omega-3 that are reported scientifically to provide cardiovascular benefits.

Using data from the scientific literature, the reviewers calculated that an omega-3 index value of eight per cent or above is associated with a 90 per cent reduction in the risk of sudden cardiac death, compared to a value of four per cent or less. The “omega-3 index” is defined as the percentage of EPA plus DHA in red blood cell membranes, relative to all other fatty acids.

Washing Produce in Vinegar + Hydrogen Peroxide Kills E. Coli

Here is a timely article that has not been reprinted in the mass media. With the current scare of contaminated spinach, it seems that spinach processors and food distribution facilities, as well as consumers would find this of interest.

Susan S. Sumner, a food scientist at Virginia Polytechnic Institute and State University (Blacksburg, Virginia), has found that misting fruits and vegetables with vinegar and three percent hydrogen peroxide (commonly sold in stores) kills attached microbes, including E. Coli, Salmonella and Shigella.

Studies performed in the 1990s showed that rinsing produce in water or even using a detergent does little to remove microbes. Sumner used simple laundry spray bottles to mist produce with vinegar and then with hydrogen peroxide. The combination is highly effective and causes little effect on the food's taste. Which solution is applied first makes no difference, but using the two in combination is key.

Chromium Helps Control Weight and Improve Insulin Sensitivity in Diabetics

A new study published in the August 2006 issue of Diabetes Care has found that chromium picolinate helps diabetics maintain normal weight and improve insulin sensitivity. In the study, 37 patients with type 2 diabetes were given a common type 2 diabetes prescription drug and a placebo for three months. Patients were then randomly assigned to one of two groups and either kept on the sulfonylurea-placebo regimen or given 1,000 micrograms of chromium picolinate for six months.

Compared to those in the sulfonylurea -chromium picolinate group, those in the sulfonylurea-placebo group had a “significant increase” in body weight (4.84 lbs vs. 0.9 lbs), body fat (1.17% vs. 0.12%), and total abdominal fat (32.5 cm2 vs. 12.2 cm2) over the course of the study.

Decreasing Omega-6 to Omega-3 Ratio Improves Prostate Health

The two classes of polyunsaturated fatty acids that influence prostate cancer are omega-6 and omega-3 fatty acids. Pro-inflammatory omega-6 fatty acids stimulate prostate cancer cell growth, while anti-inflammatory omega-3 fatty acids inhibit this growth. Omega-6 fatty acids are found in vegetable, corn, safflower, and cottonseed oil. Omega-3 fatty acids are found in flaxseed, fish oil and krill oil.

A new study has found that the key to promoting prostate health may lie in maintaining a healthy ratio of n-6 to n-3 fatty acids in your body. The researchers concluded, “dietary intervention trials incorporating omega-3 supplements (DHA and EPA) with reduced dietary omega-6 fatty acid . . . may play an important role in primary and secondary prostate cancer prevention.”

Omega-3 Fatty Acids Show Long-Term Benefits Against Depression

Depression has been found to be caused by a number of conditions, including osteoporosis, stroke, and type 2 diabetes. It effects an estimated 18 million Americans. While supplements like St. John’s Wort reduce minor to moderate depression, the fact that depression’s root causes reside in the brain leaves omega-3 fatty acids as perhaps the best way to help promote mental health.

Previous research has shown that omega-3 fatty acids found in fish oil (called EPA and DHA), promote mental health by helping decrease inflammatory proteins.

The researchers found that depressed males had significantly lower levels of DHA and EPA in fat tissue than non-depressed males while no significant differences were seen in the blood measurements. The fact that researchers found measuring fat tissue levels to be better predictors of depression than blood levels is thought to be due to the slow rate of deposition of omega-e fatty acids in the brain.

Mediterranean Diet Reduces Heart Disease Risk Factors

The health benefits of the Mediterranean Diet have been shown to be very diverse, including helping maintain normal blood pressure levels, improving blood lipid profiles, reducing systemic inflammation, and supporting normal blood vessel function. Mediterranean Diets have also been found to increase antioxidant levels.

The researchers found that compared with a low-fat diet, the Mediterranean diet produced beneficial changes in most of the risk factors for heart disease, including significant decreases in blood sugar, as much as a 7.1 mm Hg drop in systolic blood pressure, improvements in the ratio of total cholesterol to HDL cholesterol, and a significant (0.54 mg/L) decrease in C-reactive protein, a marker of inflammation.

Soy Helps Maintain Healthy Bone Density in Women

As a health concern that faces one in three postmenopausal women, osteoporosis causes 90% of all hip fractures, results in more than 2.5 million physician visits, 432,000 hospitalizations, and 180,000 nursing home admissions each year and costs the US healthcare system more than $15 billion each year.

The researchers found that higher dose of isoflavones had a significant effect on helping slow bone loss compared to placebo and that the bone-specific urine biomarker of bone loss, called Dpd, was significantly decreased in both soy groups compared to placebo. But the significant decrease in bone loss in the higher soy group caused the researchers to suggest that “the optimal intervention dose might be larger than 80–90 mg isoflavones per day for the prevention of bone loss in this population.”

Vitamin E Alpha-Tocotrienol Helps Maintain Nervous System Health

Tocotrienols, a form of vitamin E, may help maintain the health of the nervous system, explaining the inconsistent results of previous Parkinson's studies and drawing attention to this least studied form of vitamin E.

There are eight forms of vitamin E: four tocopherols (alpha, beta, gamma, delta) and four tocotrienols (alpha, beta, gamma, delta). Alpha-tocopherol is the form found in most supplements, while gamma-tocopherol is the most common form in the American diet, and dl-alpha tocopherol is the synthetic form found in cheap supplements. It has also been found that high-dose alpha-tocopherol (usually from older-science based supplements) inhibits the uptake of gamma and delta tocopherols and possibly tocotrienols.

The researchers found that alpha-tocotrienol, but not alpha-tocopherol, “completely inhibited” HCA toxicity, thereby “demonstrating increased neuroprotective ability” of alpha-tocotrienol compared to alpha-tocopherol.

Vitamin D Limits Falls in Elderly

Poor vitamin D status is independently associated with an increased risk of falling in the elderly, particularly in those aged 65–75.

Conducted by researchers in The Netherlands, the study involved 1,231 men and women aged 65 and older. They were tracked for one year, during which time 33% fell at least once and just over 11% fell two or more times.

Overall, men and women who were deficient in vitamin D at the outset were 78% more likely than those with adequate levels to fall at least twice. Their risk of falling three or more times was more than doubled.

Obesity Rates Continue to Increase

According to a report by Trust for America’s Health (TFAH) in September 2006, adult obesity rates continued to rise in 31 states over the past year.

Jeff Levi, executive director of TFAH said, “Quick fixes and limited government programs failed to stem the tide. The ‘fad diet’ approach does not work for individuals, and it’s not going to work for our nation’s obesity crisis either."

Consider stevia as an alternative zero-calorie, zero-glycemic sweetener and pinolenic acid as a natural appetite suppressor. For a comprehensive weight management program, view Dr. Nicholas Perricone's weight loss diet.

Low Vitamin E Intake During Pregnancy Can Lead to Childhood Asthma

Children whose mothers had a low intake of vitamin E during pregnancy are more likely to develop wheezing and asthma by age five.

The researchers studied respiratory status in 1,253 mothers and children during a five-year period. They reported that children's airways are fully developed by 16 weeks after conception and, consequently, vitamin E exposure in early pregnancy may be more likely to influence airway function than exposure later in pregnancy.

According to the authors, children born to mothers from the lowest quintile of vitamin E intake were over five times more likely to manifest early persistent asthma than children whose mothers were in the highest quintile.

70% of Teenage Girls Vitamin D Deficient

Over 70 per cent of seemingly healthy teenage girls may be vitamin D deficient, says a British study, and they are at increased risk of osteoporosis and other health problems later in life.

“Vitamin D deficiency during childhood and adolescence might impair the acquisition of peak bone mass at the end of skeletal growth and maturation, thereby increasing the risk of osteoporotic fracture in later life,” explained the researchers from Saint Mary's Hospital for Women and Children in Manchester.

The researches report that 73 per cent of the girls were vitamin D deficient, with levels of 25(OH)D below 30 nanomoles per litre of serum. Nine girls (17 per cent) had levels below 12.5 nanomoles per litre. These low levels are typically associated with rickets and osteomalacia.

L-Arginine May Help Prevent Malaria in Children

The amino acid L-arginine may be helpful in preventing and treating children with malaria, according to a research letter in The Lancet.

The body uses arginine to produce nitric oxide (NO). In vitro experiments have shown that NO is anti-parasitic. It may also protect against malaria by decreasing pro-inflammatory cytokines and by lessening endothelial cell surface adhesion, thereby preventing protozoa from adhering to cells.

The researchers identified an inverse correlation between plasma L-arginine concentrations and severity of malaria in Tanzanian children.

CLA Promises Benefits for Diabetics

Conjugated linoleic acid (CLA) shows promise to improve insulin action, and decrease circulating glucose levels, with rat and human studies both reporting significant benefits.

Professor Jack Vanden Heuvel, co-director of Penn State's Center of Excellence in Nutrigenomics, has suggested that incorporating CLA as a dietary supplement or from enriched foods, in addition to a balanced diet, could be a suitable way of helping diabetics control their blood glucose and insulin levels.

“The eight-week number that was quoted actually comes from examining the review articles on the human studies. By eight-weeks of CLA [supplementation] you see a reduction in body fat (in most studies); since body fat is causally related to diabetes, I interpret this to mean that there is an improvement in diabetes,” Vanden Heuvel said.

Bone Death in Women Taking Osteoporosis Drugs

Harvard Women's Health Watch, in the September 2006 issue, reports that a connection between certain bone-strengthening drugs and the death of bone tissue. The drugs, known as bisphosphonates, include Fosamax, Actonel, Boniva, Skelid, Didronel, Zometa, Aredia, and Bonefos.

They are widely prescribed for osteoporosis and are also used to treat bone pain and other complications in cancer patients. Bisphosphonates increase bone density in the short run, but in the long run they may impair new bone formation. Scientists think this may reduce the jawbone’s capacity to heal after traumas such as dental extractions or implants.

Researchers at Harvard say the best treatment is prevention. We suggest you prevent this terrible condition by not taking these drugs. There are so many less expensive alternatives that help increase bone density naturally. Here is one recent article Vitamin K Supplementation Increases BMD and Reduces Hip Fracture 80%.

L-Arginine Enhances Endurance Exercise Tolerance in Heart Failure Patients

Heart failure patients who consume supplements of the amino acid L-arginine experience enhanced exercise endurance, according to French researchers.

The researchers set out to determine whether six weeks of oral L-arginine supplementation could affect endurance exercise performance, an important determinant of daily-life activity, in chronic stable heart failure (CHF) subjects.

The researchers concluded, “In heart failure patients, six weeks’ oral L-arginine supplementation enhances endurance exercise tolerance, reducing both heart rate and circulating lactates. This suggests that chronic L-arginine supplementation might be useful as a therapeutic adjuvant in order to improve the patient's physical fitness.”
