Garlic Is Good For Your Brain

April 1, 2015 7:55 am 0 comments

imgresNo. Garlic won’t make you smarter, but according to researchers at the University of Missouri School of Medicine, it might protect your brain against aging and disease. A U of Missouri news release reports that researchers at the school focused on a carbohydrate derivative of garlic known as FruArg and the role this nutrient plays in protective responses, paying particular attention the nutrient’s ability to inhibit ― and even possibly reverse ― brain cell damage caused by environmental stress. What did they find? The envelope please…..When FruArg was applied to model microglial cells, the cells adapted to the stress by reducing the amount of nitric oxide they produced. That’s important because excessive production of nitric oxide leads to brain cell damage and promotes neurodegenerative diseases such as cerebral ischemia, Parkinson’s disease and Alzheimer’s disease. Wait, there’s more: FruArg promoted the production of antioxidants, which offered protective and healing benefits to other brain cells.

Air Pollution Shouldn’t Stop You From Exercising

L_ber_ved_s_erne_250Forget about putting off running because there’s too much air pollution. A new study from the University of Copenhagen finds that the benefits of exercise trump the negative effects of air pollution, at least when the measure is mortality. A news release from the University of Copenhagen reports that researchers at the school studied the exercise habits of more than 52,000 people, 50 to  65 years old, and living in two cities: Copenhagen and Aarhus. The researchers then measured air pollution at the addresses of the study subjects. The envelope please…… The researchers observed about 20 percent fewer deaths among those who exercised than among those who didn’t exercise, even for those who lived in the most polluted areas, in central Copenhagen and Aarhus, or close to busy roads and highways.

Can Sweet ‘N Low Stall Cancer?

March 30, 2015 7:43 am 1 comment

Remember when Sweet ‘N Low and other foods with saccharin caused cancer? Scratch that. New research from the University of Florida suggests that saccharin can actually inhibit the growth of some cancers. It’s true. imgresA University of Florida news release reports that Brian Mahon, a curious UF graduate research assistant wanted to know how saccharin might affect the enzyme, carbonic anhydrase IX, which is found in aggressive cancers. “So we just went to a coffee shop and got some Sweet ‘N Low. I said, ‘Let’s just try it’ and we did and collected some data,” Mahon recalled. After doing some initial experimenting, he and his fellow researchers found that saccharin disrupts carbonic anhydrase IX’s ability to regulate the cancer cell’s pH level — its hydrogen ion concentration, which makes it harder for the cancer cell to grow and metastasize. Targeting carbonic anhydrase IX is also an attractive option, according to the news release, because it’s not expressed in most other cells throughout the body, meaning that healthy tissue should remain unaffected even as cancer cells are weakened. What’s next? The researchers want to further test saccharin’s effectiveness in cancer cells and eventually move to mouse models.

Fitness Cuts (Some) Cancer Risk In Half

March 27, 2015 7:33 am 0 comments

First, the numbers: 13,949 men were given a treadmill test to determine cardiorespiratory fitness (CRF). During an average 6.5 years, 1,310 of them were diagnosed with prostate cancer, 200 with lung cancer and 181 men with coloimagesrectal cancer. Researchers found that men with a high CRF in midlife had a 55 percent lower risk of lung cancer and a 44 percent lower risk of colorectal cancer compared to men with low CRF. And now the bad news: the same association was not seen between midlife CRF and prostate cancer. Why? Science Daily reports that the researchers don’t really know, but they speculate men with high CRF may be more prone to undergo preventive screenings and therefore have a greater opportunity to be diagnosed with prostate cancer. Wait, there’s more: The study also found that high CRF in midlife was associated with a 32 percent lower risk for cancer death among men who developed lung, colorectal or prostate cancer at Medicare age compared with men with low CRF.

Don’t Get Angry: It’s Bad For Your Health

March 26, 2015 9:05 am 0 comments

How bad, exactly, isimages-1 anger for your health? Let this article in the Wall Street Journal count the ways. The journal reports that anger releases adrenaline and cortisol, which can trigger an increase in heart rate, blood pressure and sugar metabolism. That’s great if you’re being attacked by a saber-toothed tiger, but it’s not so great when you’re sitting in traffic. Long term health effects can include damage to the heart, and increased blood pressure and blood flow can damage the lining of arteries. Want studies? Here you go: A study of 300 heart attack patients published in March in the European Heart Journal: Acute Cardiovascular Care found that those who had experienced intense anger had an 8.5 times greater risk of heart attack in the two hours after the outburst than they would normally. Yes 8.5. And this: a review of nine previously conducted studies on anger and cardiovascular problems found a higher rate of problems including strokes, heart attacks and arrhythmia, or irregular heartbeat, in the two hours following an outburst of anger. Read more in the Wall Street Journal, and relax.

To Live Longer, Eat Whole Grains

March 25, 2015 7:43 am 0 comments

imagesReaders who would prefer a longer life should note well: Researchers at Harvard Medical School tracked about 370,000 people -all aged from 50 to 71- from the mid-1990s, when they took surveys, through the year 2009. The envelope please… the researchers found that those who ate the most fiber were 17 percent less likely to die during the study period than those who ate the least. But wait, the risk of death during the study was pretty low to begin with; only about 12 percent (just over 46,000) of the people died during the study period. HealthDay reports on a few other things that might influence the findings: Those who ate the most fiber were more likely to be educated, less likely to be obese and less likely to smoke than those who ate the least. The whole grain eaters also ate much less red meat. OK, how many whole grains does one have to eat to be a whole grain eater?  The researchers defined heavy eaters of whole grains — those with the greatest life span benefits — as those who ate 34 grams of whole grains for every 1,000 calories they consumed per day. That’s the  equivalent of five slices of whole wheat bread or 5 cups of whole-grain breakfast cereal.

More Exercise = Better Sex

March 24, 2015 7:54 am 0 comments

Let’s gobc-a+case+for+romance right to the numbers: How much exercise does a man have to do to have noticeably better sex? Answer: Two hours of strenuous exercise, 3.5 hours of moderate exercise, or six hours of light exercise a week. For those readers interested in more information, there’s this: HealthDay reports that researchers at the Cedars-Sinai Center for Integrated Research in Cancer and Lifestyle in Los Angeles surveyed nearly 300 men about  their physical activity levels and their ability to have erections and orgasms, the quality and frequency of erections, and their overall sexual function. The envelope please…. the researchers found that better sex was reported by those who engaged in the equivalent of two hours of strenuous exercise, 3.5 hours of moderate exercise, or six hours of light exercise a week. Wait, there’s more: the men who exercised less had lower sexual function scores.

Vitamin D May Slow Some Prostate Cancer

March 23, 2015 9:02 am 0 comments

imgresOver the years, vitamin D has been hailed, and often unhailed, as a cure for several unpleasant conditions. Now comes research from the Medical University of South Carolina suggesting that it can slow the progression of some non-aggressive prostate cancers. Science Daily reports that researchers at the school conducted a randomized, controlled clinical trial, which assigned 37 men undergoing elective prostatectomies either to a group that received 4,000 U of vitamin D per day, or to a placebo group that didn’t receive vitamin D. The men’s prostate glands were removed and examined 60 days later. The envelope please… Preliminary results show that many of the men who received vitamin D showed improvements in their prostate tumors, while the tumors in the placebo group either stayed the same or got worse. Note well: all of the men in the study had low-grade prostate cancers, with Gleason scores of 6 and below. There is no evidence that vitamin D can slow aggressive prostate cancer.

Drinking Milk May Stave Off Alzheimer’s

March 20, 2015 7:46 am 2 comments

Drinking wine may beimgres good for your heart, but for brain health, you may need another beverage: milk. Researchers at the University of Kansas Medical Center who asked 60 people about their milk consumption and took scans of their brains are convinced that people who drink a lot of milk have higher levels of glutathione in their brains. Why do we care? Because glutathione could help stave off oxidative stress and the resulting damage caused by reactive chemical compounds produced during the normal metabolic process in the brain. And why do we care about that? Because oxidative stress is associated with a several unpleasant diseases and conditions, including Alzheimer’s disease and Parkinson’s disease. Got milk?

For Women, More Sleep = More Sex

March 19, 2015 7:52 am 0 comments

At least two good images-2things often happen in bed, and now researchers at the University of Michigan Sleep and Circadian Research Laboratory believe they are related. HealthDay reports that scientists at the sleep lab surveyed 171 college-age women, who kept diaries of their sleep for 14 consecutive days and reported whether they engaged in sexual activity the next day. The envelope please….yes, longer sleep time was linked with greater sexual desire the next day. Wait, there’s more: women with longer average sleep duration said they had better genital arousal than women with shorter sleep time. How long is long? On average, the women reported sleeping 7 hours, 22 minutes.
