Eight Nutrients That Protect An Aging Brain

April 16, 2015 8:03 am 0 comments

We’imagesll worry about aging bodies another day. Today, we pass along, from Science Daily, a list eight nutrients that experts at the Institute of Food Technologists (IFT) believe will protect an aging from, well, aging.

1. Cocoa Flavanols: Cocoa flavanols, yes they’re found in cocoa, have long been know to improve circulation and heart health, and preliminary research shows a possible connection to memory improvement as well. Where to find them? Chocolate, and especially cocoa powder.

2. Omega-3 Fatty Acids: A study on mice found that omega-3 polyunsaturated fatty acid supplementation appeared to result in better object recognition memory, spatial and localizatory memory (memories that can be consciously recalled such as facts and knowledge). Where to find them?  Salmon, flaxseed oil, and chia seeds.

3. Phosphatidylserine and Phosphatidic Acid: Two pilot studies showed that a combination of phosphatidylserine and phosphatidic acid can help benefit memory, mood, and cognitive function in the elderly. Where to find it? Soy lecithin.

4. Walnuts:  Researchers believe walnuts may reduce the risk, delaying the onset, or slow the progression of Alzheimer’s disease — in mice. Where to find them? You know the answer to that one.

5. Citicoline: Citicoline is a natural substance found in the body’s cells that helps in the development of brain tissue. It is believed to regulate memory and cognitive function, enhance communication between neurons, and protect neural structures from free radical damage. Where to find it? Citicoline is sold as a supplement under a variety of brand names: Ceraxon, Cognizin, NeurAxon, Somazina, Synapsine,

6. Choline: Choline helps with the communication systems for cells within the brain and the rest of the body, and it may support the brain during aging and help prevent changes in brain chemistry that result in cognitive decline and failure. Where to find it? Eggs.

7. Magnesium: Magnesium supplements are recommended for people who have had a concussion. Where to find it? Avocado, soy beans, bananas and dark chocolate.

8. Blueberries: Blueberries have antioxidant and anti-inflammatory powers, mainly because of their high concentration of anthocyanins, a flavonoid that could also offer neurocognitive benefits such as increased neural signaling in the brain centers. Where to find them? That’s an easy one.


 

Wide Hips Don’t Slow Runners

April 14, 2015 4:12 pm 0 comments

It’s not true, as is often said, that people (yes, women) with wide hips make lousy runners. Now comes a researcher at Boston University whose research suggests that wide-hipsters can run just as well as narrow-hipsters. A BU Research storyh_research_Lewton-PLOS-ONE-treadmill-participant1 reports that scientists at the school recruited 38 undergraduate men and women, and had them walk and run on a treadmill while gauging how hard they were working by measuring their oxygen consumption. The runners’ motion was tracked by eight cameras trained on infrared markers attached to the participants’ hips, knees, ankles, thighs, and shanks, and the researchers estimated the subjects’ hip width using the results from the infrared trackers. The researchers expected to find that people with wider hips run and walk less efficiently than those with narrow ones, but that wasn’t what they found. In fact, they found no connection at all between hip width and efficiency: wide-hipped runners moved just as well as their narrow-hipped peers.

Muscle-Building Supplements Linked To Cancer

No, it’s not imgresbetter to look good than to feel good, especially if looking good requires muscle-building supplements that contain creatine or androstenedione, two additives that may increase the risk of testicular cancer. How do we know? Because a Brown University news release reports that researchers at the school interviewed nearly 900 men, 356 of whom had been diagnosed with testicular germ cell cancer, and 513 who had not, asking not only about their supplement use but also about a wide variety of other possible factors such as smoking, drinking, exercise habits, family history of testicular cancer, and prior injury to their testes or groin. The envelope please….The researchers found that the men who used supplements had a 1.65 odds ratio (a 65-percent greater risk) of having developed testicular cancer compared to the men who did not use supplements. Wait, there’s more. The risk was particularly high for men who began taking the supplements before they turned 25.

The Health Problem For Night Owls

April 10, 2015 8:45 am 0 comments

Night owls may be the cool people, but according to a new study imgresby researchers at the Korea University College of Medicine, they are also the unhealthy people. Writing in the New York Times, Nicholas Bakalar reports that the researchers recruited 1,620 men and women, ages 47 to 59, and surveyed their sleeping habits to distinguish the morning people from the night owls. Then they collected data about glucose tolerance, body composition and waist size, as well as other health and behavioral characteristics. What did they find? The envelope please….. Men who were night owls were far more likely to have diabetes, and women night owls were more than twice as likely to have metabolic syndrome — high blood sugar levels, excess body fat around the waist, and abnormal lipid readings. Why? Bakalar tells us that the researchers don’t really know, but they suggest that consuming more calories after 8 p.m. and exposure to artificial light at night can both affect metabolic regulation. Want to know if you’re a night owl? The Times offers short questionnaire to help you find out.

Why Women Like Long Distance Runners

April 9, 2015 8:58 am 0 comments

Why do women like long distance runners? Don’t ask a woman; ask a biological anthropologist, specifically, a biological anthropologist at the University of Cambridge, where researchers think the reason is deep in our past: better runners make better hunters, and better hunters are nicer people. A University of Cambridge news releaseimages reports that researchers at the school studied marathon runners, using finger length as a marker for hormone exposure, and found that people who experienced higher testosterone in the womb are also better at distance running – a correlation particularly strong in men, although also present in women. So what? The researchers believe that the finding demonstrates that males with greater “reproductive potential” from an evolutionary standpoint are better distance runners and suggests that females may have selected for such athletic endurance when mating during our hunter-gatherer past, perhaps because ‘persistence hunting’ – exhausting prey by tirelessly tracking it – was a vital way to get food. Wait, there’s more. Because previous studies have shown that those exposed to more prenatal testosterone have a longer ring finger (4th digit) in comparison to their index finger (2nd digit), the researchers analyzed 542 runners (439 men; 103 women) at the Robin Hood half marathon in Nottingham by photocopying hands and taking run times and other key details just after runners crossed the line. The envelope please…They found that the 10 percent of men with the most masculine digit ratios were, on average, 24 minutes and 33 seconds faster than the 10 percent of men with the least masculine digit ratios. The correlation was also found in women, but was much more pronounced in men, suggesting a stronger evolutionary selection in men for running ability. The 10 percent of women with the most masculine digit ratios were, on average, 11 minutes and 59 seconds faster than the 10 percent with the least masculine.

 

 

Many Diet Supplements Contain Dangerous Chemicals

April 8, 2015 8:13 am 0 comments

In Decemimgresber, Canadian authorities banned the sale of diet and workout supplements that contain BMPEA, calling the chemical, which is nearly identical to amphetamine, a “serious health risk.” Curiously, in the United States, the FDA took no such action, even though it had found that nine of 21 supplements tested contained the same chemical as long as two years ago. Strange? It gets more strange. Writing in the New York Times, Anahad O’Connor reports that the federal agency never made public the names of the products or the companies that made them, did not recall the products or warn consumers of the danger. O’Connor says the F.D.A. said in a statement that its review of supplements containing the stimulant “does not identify a specific safety concern at this time.” Wait, there’s more. When Dr. Pieter A. Cohen, the lead author of the new study published Tuesday and an assistant professor at Harvard Medical School tested the supplements, he and other academics found the dangerous chemical in 11 of 21 products. Cohen says companies often spike weight-loss and exercise supplements with amphetamine-like chemicals, then hide them on their labels under the names of obscure plants, such as acacia rigidula, a shrub native to Mexico and southern Texas. See which supplements were found to contain BMPEA in the New York Times.

No, You Won’t Have A Heart Attack While Exercising, Probably

April 7, 2015 7:52 am 0 comments

The next time yimagesour spouse warns you not to push too hard while exercising because you might have a heart attack, remind him or her of the findings of this recent study by the Cedars-Sinai Heart Institute study. Researchers at the institute studied the 1,247 people aged 35-65 from the Portland, Oregon, metropolitan area who had a sudden cardiac arrest between 2002 and 2013. The envelope please… they found that just 5 percent, or 63 people, had a sudden cardiac arrest during sports activities.  Eighty-seven percent of those who had a sudden cardiac arrest while engaged in sports received cardiopulmonary resuscitation. Fifty-three percent of patients who had a sudden cardiac arrest while not playing sports received cardiopulmonary resuscitation.  Science Daily reports that the survival rate of 23 percent was markedly higher for those who had a sudden cardiac arrest while exercising compared to just 13 percent for those who had a sudden cardiac arrest during other activities.  Men were seven times more likely than women to have a sports-related sudden cardiac arrest. Translation, you probably won’t have a heart attack while exercising, but if you do, you’ve got a much better chance of survival than someone who had a heart attack doing something other than exercising.

Nuts May Be The Ultimate Health Food

April 6, 2015 8:29 am 0 comments

imgresWriting in the New York Times, Jane Brody tells us something remarkable about nuts: the more you eat, the less likely you are to die at any given age, especially of cancer or heart disease. How does she know that? Brody cites a series of large studies, including the Nurses’ Health Study of 76,464 women and the Health Professionals Follow-Up Study of 42,498 men, sufficient evidence for most readers, but perhaps not for Brody herself, who points out that these studies involved well-off and well-educated people, who are likely to live longer no matter what they eat. But wait, there’s more: a new study of more than 200,000 men and women in the Southern United States and Shanghai, found that the more nuts people consumed, the lower their death rates from all causes and especially from heart disease and stroke. And more: contrary to what many believe, nuts do not make you fat. Brody points out that people in studies that included nuts in a weight-loss regimen lost more weight and ended up with a smaller waist and less body fat than participants who did not eat nuts.

Fish Oil Does Nada For Your Heart

April 3, 2015 8:43 am 0 comments

Yikes! According to Anahad O’Connor in the New York Timesimgres, about ten percent of Americans take fish oil regularly, and most of them think it’s good for their heart. Oops. As O’Connor reports, the vast majority of clinical trials involving fish oil have found no evidence that it does anything to lower the risk of heart attack and stroke. And they looked hard. Between 2005 to 2012, at least two dozen studies looked at whether fish oil could prevent cardiovascular events in people who had a history of heart disease or strong risk factors for it, like high cholesterol, hypertension or Type 2 diabetes. What did they find? The envelope please… O’Connor reports that all but two studies found that compared with a placebo, fish oil showed no benefit.

The More You Sweat, The Better You Smell

April 2, 2015 8:46 am 1 comment

The more youimages-1 sweat, the better you smell. That, at least, is the claim of researchers at Queen’s University in Belfast, who have come up with a perfume delivery system that releases more of its aroma when it comes into contact with moisture. Hence, the more you sweat, the more aroma is released, and the better you smell, if you happen to like the aroma. A Queen’s University news release reports that the perfume system also has the ability to remove the bad odors that come from sweat, because the sweat’s bad smelling ‘thiol’ compounds are attracted to the liquid, attaching themselves to it and losing their potency. Sounds great; how do we get some? Here’s the answer: Researchers are currently working with a perfume development company to identify a number of product ideas that could eventually be sold in shops.
