An article published in the Journal of Alzheimer’s Disease reveals a decreased rate of cognitive deterioration in Alzheimer’s disease patients who had higher levels of omega-3 fatty acids.*
The study included 174 men and women with Alzheimer’s disease who were randomized to receive a low-does omega-3 supplement that provided 150 mg EPA and 430 mg DHA per day or a placebo for six months, followed by a six month period during which all participants were supplemented with omega-3. Plasma omega-3 fatty acid levels and cognitive performance were assessed at the beginning of the study, and at six and 12 months. (more…)
Your favorite cold medicine could be shrinking your brain.
A new study reveals that drugs used to treat colds and a range of other common health issues, including allergies, heartburn, hypertension, insomnia, and depression, may erode gray matter and increase the risk for dementia and other cognitive problems in older adults.
Over-the-counter and prescription medications, such as Tylenol PM, Benadryl, Claritin, Dimetapp, Paxil, Xanax, Zyrtec, Lasix, and Coumadin, belong to a class of drugs known as anticholinergics. They work by blocking acetylcholine, a chemical that transmits electrical impulses between nerve cells. Using PET and MRI scans, researchers from Indiana University School of Medicine examined the brain structure and metabolism of 451 people with an average age of 73. The study found those taking anticholinergic drugs had smaller brains and lower levels of glucose metabolism, particularly in the hippocampus – a brain region involved with memory that is vulnerable to early-stage Alzheimer’s disease. People on anticholinergics also performed less well on tests measuring short-term memory and executive functions, including planning, verbal reasoning, and problem solving.
Alzheimer’s patients are deficient in acetylcholine, which is why, the researchers warn, these drugs could trigger or worsen the disease. If taking them is absolutely necessary, study author Shannon Risacher tells Time.com, “I’d suggest that doctors monitor medications and their effects, and use the lowest dose that’s effective.”
If you are serious about tackling the effects of growing older, the findings of research from the University of Guelph may cause you to change your approach to nutrition. The new study has revealed how omega-3 fatty acids fight aging and can help ward off disease and both physical and mental impairments associated with advancing age. The omega-3 fatty acids used in the study were those most abundant in fatty fish and typically provided in fish oil supplements: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
The researchers set out to see how fish oil supplements containing EPA and DHA impacted changes associated with aging, such as decrease in metabolic rate and muscle mass and increase in body fat, as well as on vital factors, including blood pressure, heart rate, and measures of c-reactive protein, glucose, insulin, and triglycerides. Twenty-four healthy, older women (mean, 66 years) were given either 3 grams of EPA/DHA or a placebo daily for 12 weeks. Here’s what they found. (more…)
A recent study verified what researchers suggested 24 years ago: that sperm concentration and the percentage of normal-looking sperm are declining dramatically. What are the reasons for these changes in the viability of sperm? A first-of-its-kind study from Harvard researchers has identified one reason and explains how diet can impact your sperm count and quality, which is especially important if you are trying to conceive.
First, however, let’s look at what’s happened to the state of sperm over the past few decades. (more…)
The findings of a new review suggest that dietary omega-3 fatty acids from fish oil fight prostate cancer on several levels. Although this is not the first study to show a positive relationship between fish oil and the growth and progression of prostate cancer, it does, according to the authors, “underscore the potential of fish oil in modulating the clinical course of human prostate cancer through the immune system.” (more…)
Results of a new meta-analysis and review suggest that the presence of benign prostatic hyperplasia (BPH) increases the risk of prostate and bladder cancer. The study evaluated both case-control studies (16 in total) and cohort studies (10 in total), and the findings are useful for clinicians and men for screening and prevention of these types of cancer.

If you are looking for natural treatments to enhance your sexual function, then you may want to consider eating these foods that have been shown to help with erectile dysfunction (ED).
Certain foods can boost testosterone levels and nitric oxide levels, resulting in better erectile function without exposing you to the side effects of erectile dysfunction drugs.
Here are our top 3 foods to eat for better sexual health based on the studies and clinical trials: (more…)
The best foods for men over 60 include foods that are going to support the heath of your heart, prostate, bones, sexual performance, and brain. Eating a healthy balanced diet is going to help keep you healthy and help you maintain a good quality of life. Men over age 60 generally require fewer calories than younger men, but vitamin and mineral requirements remain the same. So it’s more important than ever to choose nutrient-dense foods to give you the most bang for your buck and your caloric intake. (more…)
When you open your medicine cabinet, there’s a good chance the contents staring back at you are pretty hazardous to your health. Disguised in the canisters, tubes, bottles and sprays are insidious toxic ingredients that the federal government allows manufacturers to use in products men put on, and (when they penetrate your skin), in your body every day. These personal products can smell great, and that’s a big part of the problem.
Two thirds of the chemicals used by the fragrance industry have not undergone safety testing. In addition, more than three dozen chemicals not listed on the labels of big-name brand men’s personal care products were found to be either not tested or to be associated with allergic reactions, damage to sperm (and resulting infertility), and disruption of hormone levels, including testosterone, other male hormones, and thyroid hormones, according to a recent study.

How To Optimize The Way Your Body Digests Food and Turns It Into Fuel (reprinted)
The math is pretty simple: The more you exercise, the more calories you burn and the less you have to worry about eating whatever you damn well please. How our metabolism changes as we get older, though – that’s what makes things tricky.
Most of us are born with a resting metabolic rate—the number of calories we burn just to stay alive—and that baseline dictates how often we have to exercise in our twenties to offset any benders, hangovers, et al. Some of us have a fast resting metabolic rate and therefore require little to no exercise (thanks, Mom and Dad!), while others of us have a slower one and therefore require more exercise and/or patronage of a local Big & Tall emporium (add it to the list of grievances). It’s the luck of the genetic draw, and there’s not a lot anyone can do about it beyond working out and watching what you eat. (There is nothing to hack here, folks.) (more…)
