Soy peptide lunasin has anti-cancer, anti-inflammatory properties

Two new University of Illinois studies report that lunasin, a soy
peptide often discarded in the waste streams of soy-processing
plants, may have important health benefits that include fighting
leukemia and blocking the inflammation that accompanies such
chronic health conditions as diabetes, rheumatoid arthritis, heart
disease, and stroke.

leukemia and blocking the inflammation that accompanies such
chronic health conditions as diabetes, rheumatoid arthritis, heart
disease, and stroke (see also University of Illinois at
Urbana-Champaign).

In another study, the first to report lunasin’s potential
anti-inflammatory activity, they showed that lunasin blocked or
reduced the activation of an important marker called NF-kappa-B,
a link in the chain of biochemical events that cause inflammation.

Lunasin’s bioavailability in the human body was confirmed by doing a
third study in which men consumed 50 grams of soy protein–one soy
milk shake and a serving of soy chili daily–for five days.

Editor’s Note1: Note that soy flour does contain high concentrations of the peptide.
Editor’s Note2: Chronic systemic inflammation can cause or contribute to many eye conditions such as macular degeneration, diabetic retinopathy, macula edema, optic neuritis, uveitis and iritis for example. Chronic inflammation is now considered a major contributor to heart disease as well.

The Deadly Connection Between Diabetes and Alzheimer’s

For example, a 2004 Study found that high insulin levels, which are intimately connected to type II diabetes, were significantly correlated with a higher risk of developing Alzheimer’s.

Numerous studies connect diabetes and Alzheimer’s Disease.

A study in 2004 examined the association between type II diabetes, high insulin levels, and Alzheimer’s risk. A total of 683 men and women were followed and examined for signs of Alzheimer’s and increased insulin levels. As in the earlier study, the scientists found that high insulin levels, which are intimately connected to type II diabetes, were significantly correlated with a higher risk of developing Alzheimer’s.

Luchsinger JA, Tang MX, Shea S, Mayeux R. Hyperinsulinemia and risk of Alzheimer disease. Neurology. 2004 Oct 12;63(7):1187-92.

The possible mechanism by which high insulin levels are linked to Alzheimer’s was elucidated in a 2005 study published in the Archives of Neurology. Researchers showed that by mimicking high insulin levels (such as those seen in patients with insulin resistance and type II diabetes) in 16 healthy men ranging in age from 55 to 81, they were able to elevate inflammatory markers and beta amyloid levels in the brain, two characteristics of Alzheimer’s disease.

One’s Own Stem Cells May Be Key to Treating Angina

The largest national stem cell study for heart disease showed the first evidence that transplanting a potent form of adult stem cells into the heart muscle of subjects with severe angina results in less pain and an improved ability to walk. The transplant subjects also experienced fewer deaths than those who didn’t receive stem cells

The largest national stem cell study for heart disease showed the first evidence that transplanting a potent form of adult stem cells into the heart muscle of subjects with severe angina results in less pain and an improved ability to walk. The transplant subjects also experienced fewer deaths than those who didn’t receive stem cells

Out of the estimated 1 million people in the U.S. who suffer from chronic, severe angina which is chest pain due to blocked arteries, about 300,000 cannot be helped by any traditional medical treatment such as angioplasty, bypass surgery or stents.

“This is the first study to show significant benefit in pain reduction and improved exercise capacity in this population with very advanced heart disease,” said principal investigator Douglas Losordo, M.D., the Eileen M. Foell Professor of Heart Research at the Northwestern University Feinberg School of Medicine and a cardiologist and director of the program in cardiovascular regenerative medicine at Northwestern Memorial Hospital, the lead site of the study.

Vitamin D Helps Boost Immunity to Colds

A new study reinforces the role that Vitamin D plays in preventing colds and other respiratory tract infections.

Researchers using data from 18,883 participants in the Third National Health and Nutrition Examination Survey found that Vitamin D could boost immunity to colds, even after adjusting for demographic and clinical factors such as season, body mass index, and smoking history.  The study, published in the journal Archives of Internal Medicine reinforces the importance of Vitamin D in avoiding upper respiratory tract infections.

Vitamin D is produced by the body when exposed to direct sunlight.   It is crucial for people with limited sun exposure (such as during winter months) to include Vitamin D in their diet.  Good sources of Vitamin D include fatty fish, fish liver oils, and eggs.

Elevated Cysteine Levels May Be Important Indicator for Future Heart Disease

In a study of more than 1,200 people undergoing cardiac imaging at Emory because of suspected heart disease, people with high levels of cysteine in the blood were twice as likely to have a heart attack or die over the next few years.

In a study of more than 1,200 people undergoing cardiac imaging at Emory because of suspected heart disease, people with high levels of cysteine in the blood were twice as likely to have a heart attack or die over the next few years.

Cysteine could be a valuable marker of cardiovascular risk, but it also has a direct harmful effect on cells, so reducing it may be a valuable treatment strategy, according to researchers.

Cysteine is itself a short-lived precursor to glutathione, one of the main antioxidants found inside cells. We need to have a continuous supply of cysteine, but it is too reactive for us to have very much at any one time.

Smoking and alcohol consumption are also linked with higher levels of oxidized cysteine.

Editor’s Notes: Current research is showing other indicators to be much more accurate in predicting future heart disease than cholesterol levels including C-Reactive Protein levels, Homocysteine levels and possibly now oxidized cysteine levels.

Long-term exercise positively impacts cellular aging

In an article appearing in the December 1, 2009 issue of Circulation: Journal of
the American Heart Association, Ulrich Laufs, MD of Saarland University in Homburg,
Germany and his colleagues report an association between long-term intense exercise
and a reduction in the shortening of telomeres that occurs with aging.

the American Heart Association, Ulrich Laufs, MD of Saarland University in Homburg,
Germany and his colleagues report an association between long-term intense exercise
and a reduction in the shortening of telomeres that occurs with aging. Telomeres
are protective segments of DNA at the ends of chromosomes that shorten with cell
division. Shorter telomeres limit the number of cell divisions, and have been
linked with conditions associated with aging of the whole human organism, such
as high blood pressure and dementia.

Flaxseed Oil May Reduce Osteoporosis Risk

Adding flaxseed oil to the diet may reduce risk of osteoporosis in post-menopausal women and women with diabetes, according to new research published in the International Journal of Food Safety, Nutrition, and Public Health.

In a study using laboratory rats, researchers have found that flaxseed oil has a beneficial effect on bone mineral density and reduces markers associated with osteoporosis, suggesting that this dietary supplement may help women with diabetes in reducing their risk of osteoporosis.

Study authors believe that the presence of n-3 fatty acids in flaxseed oil may play a role in protecting the processes of matrix formation and bone mineralization, which are compromised by diabetes and menopause. Further trials with humans are recommended to confirm the effects on bone health, but the implications for use in osteoporosis prevention are encouraging.

New Study Shows Cinema popcorn to be a nutritional horror

Nutritional analysis of popcorn servings at some of America’s biggest cinema chains has found mind-boggling calorie counts that may surprise consumers who think of the snack as a relatively healthy treat.

Nutritional analysis of popcorn servings at some of America’s biggest cinema chains has found mind-boggling calorie counts that may surprise consumers who think of the snack as a relatively healthy treat.

The non-profit Center for Science in the Public Interest study compared some popcorn and drinks combos to consuming three McDonald’s quarter-pounders topped with 12 pats of butter.

At Regal Theatre movie chains for example, one medium popcorn and soda combination contained an eye-popping 1,610 calories and around 60 grams of saturated fat.

At AMC theaters, the second largest theater chain, a large popcorn contained 1,030 calories and 57 grams of saturated fat, equivalent at a pound of baby back spare ribs topped with a scoop of luxury ice cream.

The study said the high calorie counts could be attributed to the fact that corn was popped in coconut oil.

The study came out on the same day as new numbers in the U.S. suggested that by 2018, 40% of Americans will be obese. The most at-risk states for bursting at the waistline include Kentucky, Maryland, Mississippi, Ohio, Oklahoma and South Dakota.

Researchers Predict Number of Americans with Diabetic Retinopathy Will Soar By 2050

The number of Americans with diabetic retinopathy is expected to increase from 5.5 million to 16 million by the year 2050.  Diabetic retinopathy is damage to the retina caused by complications of diabetes, which can eventually lead to blindness.

Researchers used data from the National Health Interview Survey and the US Census Bureau to project the number of people with diabetic retinopathy (DR), vision-threatening DR (VTDR), glaucoma, and cataracts among Americans 40 years or older with diagnosed diabetes mellitus for the years 2005-2050.

Study results showed:

  • the number of Americans 40 years or older with DR will triple from 5.5 million in 2005 to 16.0 million in 2050
  • the number of Americans 40 years or older with VTDR will also triple, from 1.2 million in 2005 to 3.4 million in 2050
  • increases among those 65 years or older will be more pronounced (2.5 million to 9.9 million for DR and 0.5 million to 1.9 million for VTDR)
  • the number of cataract cases among whites and blacks 40 years or older with diabetes will likely increase 235% by 2050, and 
  • the number of glaucoma cases among Hispanics with diabetes 65 years or older will increase 12-fold.

Study authors stress the importance of efforts to prevent diabetes as well as to optimally manage diabetes and its complications.
