A new study appearing in the British Journal of Nutrition showed that increased blood levels of lutein and zeaxanthin may reduce the risk of cataracts by about 40% in older individuals. Cataracts are one of the leading causes of blindness among the elderly.
For the study, 1,689 participants between the ages of 61 and 80 were followed for a period of four years. There was a 42% lower risk of being diagnosed with cataracts among those whose lutein levels were among the top one-third of participants, and a 41% lower risk for those whose zeaxanthin levels were among the top third, as compared to subjects whose blood levels were in the lowest third.
Studies have repeatedly shown that these two powerful antioxidants are beneficial for eye health. Most of the research in the past has been directed toward lutein and zeaxanthin’s role against age-related macular degeneration, but this analysis shows that they are equally effective against cataract formation.
Lutein and zeaxanthin are found together in many foods. Dark green leafy vegetables are the primary source of these antioxidants, but they are also present in other colorful fruits and vegetables, such as broccoli, peppers, carrots, oranges corn and peas.

A study appearing in Annals of Neurology last week showed that increasing the consumption of blueberries and strawberries appeared to slow cognitive decline in older women. The research focused on 16,000 women over the age of 70 who were followed for a period of 6 years. The results demonstrated that those who consumed two or more servings of berries per week were able to delay memory decline by two-and-a-half years.
Another study published in The American Journal of Clinical Nutrition confirmed that flavonoids from blueberries lowered the risk of type 2 diabetes. Blueberries are capable of increasing the production of a key hormone, called adiponectin, which prevents the liver from developing insulin resistance that leads to type 2 diabetes.
This large study followed nearly 200,000 participants for who were free of diabetes, heart disease and cancer, and were tracked for a period of twenty years. Higher consumption of berry flavonoids was associated with a lower risk of type 2 diabetes “after adjusting for age, body weight, lifestyle and dietary factors.” By comparison, blood sugar levels rise in reaction to a diet consisting of highly refined carbohydrates, sugar, and the over-indulgence of processed foods.
These two studies show that increasing berry intake is a simple dietary modification that can bring about positive change in overall health.
But did you know that some common medications can cause high blood pressure? A recent study published in the American Journal of Medicine showed that the chemical components of certain drugs can raise blood pressure and doctors remain dangerously unaware. Researchers involved in the study commented that just because something can be purchased ‘over-the- counter’ doesn’t mean it’s necessarily harmless.
Many of the medications that are linked to a rise in blood pressure are quite widely used. For example, NSAIDs (nonsteroidal anti- inflammatory drugs) were shown “to produce a clinically significant increment in mean BP of 5 mm Hg.” Similarly, several studies linked acetaminophen with a notably higher incidence of elevated blood pressure in those patients with coronary artery disease.
The study also showed that decongestants and cough medicine containing pseudoephedrine, epinephrine and phenylephrine have been reported to cause severe high blood pressure in some individuals. Antidepressants were responsible for causing a mild dose-dependent increase in blood pressure among those taking them, and they were also capable of triggering high blood pressure in those who tended specifically towards panic disorders.
Hypertension develops in at least 20 percent of patients taking synthetic corticosteroids. Oral cortisol at prescribed doses of 80-200 mg/day can raise systolic BP as much as 15 mm Hg within 24 hours. Oral contraceptives can cause elevated blood pressure in roughly 5 percent of those who take them, where combined doses contain at least 50 ug of estrogen and 1-4 mg of progestin. The increased BP is usually minimal, however severe hypertensive episodes can occur.
Hypertension is a leading cause of heart attack and stroke and many people are not even aware they may have it. High blood pressure is considered anything over 140/90. So if you regularly take any of these medications, make sure to get your blood pressure checked at each doctor’s visit and let your physician know what drugs you take and how often you take them.
Eye tremors are common in Parkinson’s and can be an early warning sign of the nervous- system disease, according to a recent study published in the Archives of Neurology.
The research examined 112 Parkinson’s disease patients and compared them to 60 healthy controls. Those with Parkinson’s had trouble tracking moving targets on a computer screen, compared with only 2 of the age-matched participants used as controls.
The findings suggest that analyzing this specific eyeball movement called “oculomotor testing” can offer an early clue for identifying the nervous system disease. Used as a screening tool, this test could be close to 100% accurate, which is significant because usually eye tremors are too small to notice clinically without the use of specialized equipment.
These findings are important when it comes to identifying those who may possibly benefit from treatment, as new alternatives become available that could possibly slow the progression of this disease.
Trying to find a cure for baldness has been about as easy as trying to find a needle in a haystack. But this may all be about to change because scientists have identified a protein called PGD2 in the scalps of men with male pattern baldness. Researchers say if they can find a way to keep this protein from attaching to hair follicle receptors, they could prevent baldness.
The study, published in the Science Translational Medicine journal, examined samples from 17 men with hair loss and found that their bald scalp tissue had three times the levels of PGD2 compared with the hair-covered tissue from the same individual. PGD2 causes baldness through a receptor called GPR44. The hope is to develop a way to block this receptor.
Male pattern baldness affects 8 out of 10 men under the age of 70, and causes hair follicles to shrink and create microscopic hairs, which grow for shorter time periods than normal follicles.
The scientists in the study wrote that this discovery could very well lead to new treatments for the most common cause of hair loss in men.
While high-fat foods taste good to most of us, some people don’t enjoy the flavor of rich, fatty food at all. New research appearing in this month’s issue of the Journal of Food Science confirms that two distinct genes might have very specific functions when it comes to enjoying dietary fat. By understanding the part that these two genes play, researchers may be able to assist those who have difficulty managing the amount of fat they consume.
Investigators established the fat preference of more than 300 adults who possessed the CD36 “fat receptor “gene. They found that 21 percent of these study participants had a higher preference for added fats like salad dressings and oils.
The researchers also investigated another gene — the TAS2R38 gene — which controls bitter taste. About 70 percent of the population are “tasters” of these compounds, while the rest of the population are “nontasters.” Results of this research imply that nontasters of these compounds have a difficult time detecting dietary fat in foods and may consume higher-fat foods to compensate.
While the reason for weight gain has always been multifactorial, health professionals continue to examine the role that genotypes may play in weight management.
According to a new study published in the Journal of Alzheimer’s Disease, scientists have identified the particular mechanism regulated by vitamin D3 that helps clear the brain of the plaques that cause this brain-wasting disease.
In the past, both vitamin D and curcumin, the main component in turmeric, have been shown to help fight Alzheimer’s disease separately, but research now shows they may be even more effective when used together.
To test their hypothesis, scientists took blood samples from Alzheimer’s patients and healthy controls. They then isolated the macrophages – the part of the white blood cells known to target and eliminate plaque and other cellular debris that build up in the brain and can cause disease. Researchers found that the activity of the macrophages improved significantly by the synergistic action of the vitamin D3 and curcumin collectively.
“It is too early to recommend a definitive dosage of vitamin D3 to help with Alzheimer’s disease and brain health,” the researchers said; however, obtaining optimal vitamin D3 levels in the blood is simple and inexpensive to do. If one isn’t able to get their vitamin D from the sun, supplementing with vitamin D3 would be prudent. Adding curcumin to the diet using curry-enriched foods or supplementing with turmeric may be a safe way to help prevent Alzheimer’s disease.
