Could salmon and sunshine prevent brain damage?

Brain-damageWant to keep your brain in tip-top condition? Then you may want to put mackerel and mushrooms on your menu or start eating your salmon in the sun!

That’s because a new study led by University of Kentucky researchers suggests that a diet low in vitamin D causes damage to the brain.

In addition to being essential for maintaining bone health, new evidence shows that vitamin D serves important roles in other organs and tissue, including the brain.

The study, published in Free Radical Biology and Medicine showed that middle-aged rats that were fed a diet low in vitamin D for several months developed free radical damage to the brain. Additionally, many different brain proteins were damaged.  The vitamin D deficient rats also showed a significant decrease in cognitive performance on tests of learning and memory.

“Given that vitamin D deficiency is especially widespread among the elderly, we investigated how during aging from middle-age to old-age how low vitamin D affected the oxidative status of the brain,” said lead author on the paper Allan Butterfield, professor of Chemistry, director of the Center of Membrane Sciences, faculty of Sanders-Brown Center on Aging, and director of the Free Radical Biology in Cancer Core of the Markey Cancer Center. “Adequate vitamin D serum levels are necessary to prevent free radical damage in brain and subsequent deleterious consequences.”

vitamin D bookPreviously, low levels of vitamin D have been associated with Alzheimer’s disease, and it’s also been linked to the development of certain cancers and heart disease.

The elderly are particularly prone to have low vitamin D levels.

Butterfield recommends that people consult their physicians to have their vitamin D levels determined. If they turn out to be low it’s important to normalize them either through diet or sunlight exposure to help protect the brain.

low that they eat foods rich in vitamin D, take vitamin D supplements, and/or get at least 10-15 minutes of sun exposure each day to ensure that vitamin D levels are normalized and remain so to help protect the brain.
Surprisingly few foods contain vitamin D.  That’s because your body is built to get it from sunlight skin rather than from food. However, if your body has enough, it doesn’t matter whether you got it through your skin or through your stomach.

SalmonThere are three vitamin D super foods:

  • Salmon (especially wild-caught)
  • Mackerel (especially wild-caught)
  • Mushrooms (exposed to ultraviolet light)

Other food sources of vitamin D include:

  • Cod liver oil
  • Tuna canned in water
  • Sardines canned in oil
  • Milk or yogurt – fortified with vitamin D
  • Beef or calf liver
  • Egg yolks
  • Cheese

sunlightIf all that sounds a little too fishy for you, then you can boost your vitamin D from 10-15 minutes of sun exposure a day.

I’m off to get mine now!

Keeping Extra Pounds off your Holiday List

expanding SantaAlthough by now you’ve hopefully now finished the last of the Thanksgiving turkey and pumpkin pie, the holiday eating season has just begun. And, as a result, over the next month, the average American will gain one or two pounds. While that might not sound like much, the annual weight gain adds up from year to year and can lead to significant gains as the years goes by.

So, if the seams on your favorite holiday outfit are already bursting ahead of the onslaught of holiday parties, all-you-can-eat buffets, peppermint bark and eggnog, now’s the time to consider strategies to maintain your current weight and still enjoy the season.

At this time of year, most of us are bombarded with food. High calorie treats appear everywhere you look. Tables are filled with home-made cookies, gingerbread, hot apple cider, and irresistible savory appetizers. But resist you must, says Amy Moore, Ph.D., assistant professor of nutrition and dietetics at Saint Louis University.  Here’s her advice to keep you lean this holiday season:

holiday weight cartoonBe picky about your splurges. You can eat crackers and cheese any time, but the holidays are a time to sample special seasonal treats that people have spent a lot of energy preparing. So, if you’re at a holiday buffet, browse before you graze to size up your best options. If that delectable chocolate dessert beckons, enjoy a slice but pass on the brownies or soda. Allow yourself to indulge, just choose where you want to spend your calories.

Be mindful. When there’s a bowl of chips right in front of you, you are more likely to keep munching without really thinking about it. So pay attention to what you’re eating. Slow down and savor every bite, taking the time to appreciate what you’re putting into your mouth. Watch your portion size.

Plan ahead. If you know you are going to a party in the evening, eat a healthy breakfast and lunch. Don’t starve yourself; in fact, consider eating a snack to take the edge off of your hunger. Bring something healthy to potlucks so at least you can count on one healthy option being offered. Seasonal fruit such as pomegranates, clementines and cranberries are terrific holiday dishes because they are pretty, festive and, best of all, guilt free.

Conversation is calorie-free. Once you’ve taken a plate of food at a holiday gathering, step away from the table. Find a comfy space where you can talk to others. Fill up on fellowship, which is calorie-free!

Water is calorie-free, too. So, drink up. Alternate a glass of water with every alcoholic beverage to pace yourself as you celebrate and prevent a next day hang-over. Consider creating a wine spritzer by adding flavored sparkling water to your wine. Instead of drinking lemonade or soda with a meal, choose water. Not only does water fill you up, it’s also good for your digestive system, skin, muscles and kidneys.

Christmas fitness woman wearing santa hatIn addition to watching what you eat and drink, you should offset holiday calories by becoming more active. Saint Louis University associate professor of physical therapy and athletic training, Ethel Frese, DPT, offers the following tips:

Be realistic.  Becoming more active is a great way to mitigate a few extra calories, but it is not license to add massively to your diet. So, suppose you splurged and ate a 350 calorie pastry, on top of your normal daily calories. If you want to burn off all of the excess, you’ll need nearly an hour of intense exercise. While it’s not necessary to count every calorie, it is good to have a rough idea of how your calorie intake corresponds to your exercise, and know that it can take more exercise than you might think to balance out your food intake.

Everything counts. That said, don’t be discouraged. Exercise offers many overall health benefits, and burning off even an extra hundred calories a day makes a significant difference. In some cases, extra activity may be a natural part of your routine this season. Walking from the back of a packed parking lot at the mall and scouring stores for the perfect gift provides good exercise. House cleaning for company can burn calories, as can shoveling snow, playing with children and putting up decorations.

Fight the urge to hibernate. If rainy or snowy days tempt you to stay at home watching movies and reading books, be sure you don’t make a habit of avoiding outings. Bundle up and get out for fresh air and exercise. Run errands, stop by to see friends and neighbors, drop off canned goods at a food pantry, check out an exhibit at a museum or build a snowman!

Be consistent. The secret to success is to add a little bit of exercise each day. The effort really does add up, and you’ll find that daily activity makes you feel healthier, more alert, and happier in general. You’ll enjoy the season more without the sluggish feeling brought on by too many sedentary hours. Even if you don’t burn off all of the extra calories through exercise, you’ll limit the damage and in January, you’ll appreciate having only one pound to lose, instead of five.

Remember that the secret to controlling your weight is balancing the calories you take in (food) with the calories you burn. “Even the healthiest eaters need to exercise and the best exercisers need nutrition,” says Moore. “Nutrition and exercise provides the one-two punch of holiday weight management.”

Holiday DietMake your weight management mantra for the season to maintain not gain.

The Real Horror of Trick-or-Treating

halloween kidsAlthough historically All Hallow’s Eve was dedicated to remembering the dead, including saints (hallows),martyrs, and all the faithful departed believers, these days for most kids Halloween is all about the candy.

It is estimated that by the end of the evening, each child’s bag of goodies contains about 4,800 calories and has 3 cups of sugar and 1 ½ cups of fat. The real horror in the Halloween trick-or-treat bag is the contribution it plays to an already scary epidemic of childhood obesity.

halloween candyKids and teens love Halloween. It’s filled with fun parties and costumes, and free candy. Halloween can be a great time as long as parents make sure their child doesn’t go overboard eating all that candy,” said Garry Sigman, MD, director of the pediatric weight management program at Loyola University Health System.

So how can you balance healthy and happy for your kids this Halloween? Here’s some great tips from Dr. Sigmam:

  • Focus on fun, not candy. Find fun activities for your kids to do instead of just walking door-to-door getting candy. Plan a party with fun games or have a pumpkin-carving contest. You could watch a scary movie or have a costume parade.
  • Set limits. Limit the time your kids are out trick-or-treating. Instead of the pillowcase look for a small bag that they can use to collect candy. When they get home let them pick out two pieces to eat and then put the rest away in a freezer or hidden place to save for another day. All children should eat no more than one or two pieces of candy a day. If a child is obese he or she should not eat more than one or two pieces of candy a week.
  • Host a candy trade-in party. When the kids get back from trick-or-treating the candy in each child’s bag is weighed. Kids can exchange their candy for prizes based on the bag’s weight.

jack-o-oranges healthy halloween treatsAdults can also help by providing healthier alternatives to candy.  For example: Fruit leathers, packs of sugarless gum, boxed dried raisins, 100-calorie packs of cookies or snacks, granola bars, snack-sized bags of popcorn or non-food treats such as play-doh, spider rings, bubbles, temporary tattoos, sidewalk chalk or cookie cutters.

How are you planning on making your Halloween healthier?

Dying for an energy drink?

early-morning-workout-tips-300x200As someone who gets up at 4:30 am most days to go to the gym and who rarely, if ever, eats carbs, I know there is no easy way to stay fit and healthy.  But, there are others who may be tempted to look for an easier or quicker way…and to them we say- beware!

Before you reach for a weight loss supplement, or energy drink, you may want to think again. According to four separate case reports just presented at the American College of Gastroenterology’s 78th Annual Scientific Meeting in San Diego, consumption of some of these can lead to hepatitis, severe liver damage, liver failure and even death.

energy drinksUse of herbal and dietary supplements is widespread for a variety of reasons. But many patients don’t disclose supplement use to their physicians, and as such important drug side effects can be missed.

The first case report documented a case over liver toxicity and fulminant liver failure associated with the use of SlimQuick™, a weight loss supplement containing green tea extract.

A 52-year old female patient was admitted to the emergency room after one week of vomiting and progressive jaundice. The patient reported she had ingested SlimQuick™ for two days, while fasting three weeks prior to admission. Her liver biopsy was consistent with hepatic necrosis She was started on steroids but these were discontinued after two days, as liver function worsened and mental status deteriorated to the point she needed to undergo liver transplantation two days later.

In the second paper, Khadija Haroon Chaudrey, MD, presented a rare case of black cohosh-induced hepatotoxicity leading to early cirrhosis. Black cohash is often used by menopausal women to control hot flashes and other associated symptons

A 44-year-old female had developed jaundice for one month, and initial lab work revealed elevated liver function tests (LFTs). The patient had no history of alcohol intake, IV drug use, unprotected sex, recent travel outside the United States, NSAID ingestion or blood transfusions. After an unsuccessful outpatient trial of steroids, she was referred for inpatient evaluation because of gradual progression of her symptoms.

cirrhosis1The patient then reported she had started taking black cohosh about one month prior. “Her ultrasound abdomen showed nodular contour of liver consistent with cirrhosis,” said Dr. Chaudrey. “Given patient’s history of black cohosh use and the timing of her abnormal liver chemistries, it was clinically evident the culprit agent was black cohosh.”

Once the patient stopped taking black cohosh, her symptoms improved and her LFTs normalized.

The third case described acute liver failure following consumption of Rockstar® Sugar Free energy drink.

Brian Huang M.D., Chief Resident of the Internal Medicine Residency Program at Cedars Sinai Medical Center, presented a case involving a 36-year-old male without prior medical history. He sought medical attention after symptoms of right upper quadrant abdominal pain, jaundice and fatigue. After abnormal lab work, he was brought to the hospital. The patient admitted to binge drinking (10 beers in a three-hour period) prior to symptom onset. He denied consuming herbal supplements, but admitted to having three Rockstar® Sugar Free energy drinks, on a daily basis for the past year. He too, required a liver transplant.

According to Dr. Huang, “The patients’ pathology reports showed massive hepatocellular necrosis and parenchymal collapse consistent with drug-induced liver injury. We believe his prior history of binge drinking may have provided initial damage on his liver, making him more susceptible to develop liver failure. Although the patient had a history of weekend binge drinking, his liver biopsy was not consistent with alcoholic hepatitis. Thus, they determined that the liver failure was linked to the long-term energy drink consumption.

A fourth case of drug-induced liver injury was found to be associated with the advanced weight loss supplement, Ripped Fuel®. This supplement contains herbal extract with 60% flavinoids, caffeine and cacao.

scleral icterusA 36-year old female with history of depression and no prior liver disease was seen after having one week of abdominal pain, anorexia and nausea. On physical examination, she had jaundice and yellowing of her eyes. The patient had started to take Ripped Fuel® three weeks prior to developing these symptoms, to lose weight. She denied use of other herbal medicine, supplements or acetaminophen. There had been no recent changes in her depression medication.

There is a lack of knowledge about the status of Food and Drug Administration regulation of dietary supplements,” said Dr. Halegoua-De Marzio, author of the first paper. “Currently, dietary supplements are not required to have safety or efficacy studies before they are marketed to the public, and they remain popular among consumers despite reports of hepatotoxicity. 

These cases serve as a reminder of how even minimal use of dietary supplements can lead to liver failure and liver transplant. It is important that patients talk with their doctors before starting any new dietary supplements.

Or better yet, stick with the old fashioned way of healthy diet and exercise.  So who wants to join me in the gym at 5am tomorrow?

10 Brain Damaging Habits

brain damageAccording to the World Health Organization here’s 10 habits that can severely damage your brain:

No Breakfast1.  No BreakfastSkipping breakfast in order to lose weight or save time is totally wrong and directly affects our brain. Those who don’t take breakfast or take unhealthy breakfast having lower blood sugar level and sometime it may cause overweight.

2. Overreacting – causes hardening of the brain arteries, leading to a decrease in mental power.

3. High Sugar consumption – Too much sugar will interrupt the absorption of proteins and nutrients causing malnutrition and may interfere with brain development by reducing the production of Brain Derived Neutrotrophic Factor, without which the brain cannot learn.

Smoking4. Smokingcauses brain shrinkage, damages memory, judgment, learning and thinking powers and may even lead to dementia and Alzheimer’s disease.

5. Air PollutionThe brain is the largest oxygen consumer in our body. Inhaling polluted air decreases the supply of oxygen to the brain, bringing about a decrease in brain efficiency.

6. Sleep Deprivation Sleep allows our brain to rest. Long term deprivation from sleep will accelerate the death of brain cells.

7. Head covered while sleeping – Sleeping with the head covered decreases available air space and forces you to start breathing carbon dioxide instead of oxygen. This leads to a rise in intracranial pressure and results in brain hypoxia which may lead to brain damaging effects.

8. Working your brain during illness – Working hard or studying with sickness may lead to a decrease in effectiveness of the brain. When we are sick the brain is at its weakest and becomes more easily stressed. This stress can also affect memory.

9. Drinking too little water – Water is the main source of energy and is essential for brain function and activity of neurotransmitters. Dehydration can lead to anger, stress, exhaustion, depression and lack of mental clarity.

Talking Rarely10. Rarely Talking – Intellectual conversations help to train and promote efficiency of the brain. Conversely, lack of stimulating thoughts may cause brain shrinkage. Reading SRxA’s Word on Health and discussing the content with friends is an excellent way to avoid this!  So grab a glass of water and subscribe today. Consider it free brain fuel!

A Call to End Religious Nutrition

lowcarbQ: “How can you tell if a friend is on a gluten-free diet?”

A: “They’ll tell you.”

Again and again and again… Same joke goes for paleo, low-carbvegan and pretty much any organized dietary strategy that has a defining name and movement behind it.

Along with politics, gun rights, religion and abortion, is one of those areas where people feel comfortable not only sharing their views but do so with incredible conviction, passion and certainty. And yet, nutrition is anything but certain.  Sure, we know there are patterns of eating that help in minimizing the risk of various chronic diseases, but those patterns are far broader and less drilled down than most nutrition gurus and zealots believe.

So, we were very interested in fellow blogger –Yoni Freedhoff’s – recent blog in which he calls for an end of nutrition as religion.  More so, because Yoni is not just another disillusioned dieter. No siree!  He is the Medical Director of the Bariatric Medical Institute and assistant professor of family medicine at the University of Ottawa.  Dr. Freedhoff has also been called Canada’s most outspoken obesity expert and his award winning blog, Weighty Matters, has at times been ranked the world’s top health blog by blog ranking service Technorati.

So what does Dr Freedhoff have to say?

First, he suggests that practitioners of dietary religion risk alienating friends through strict adherence to their religious commandments.  Second, he states that diet adherents tend to use their online platform to frown upon any and all dietary strategies beyond their house of worship. To question their program or guru’s plans is akin to questioning their religious beliefs; and yet, unlike actual religious questioning (which would almost certainly lead to a thoughtful discussion), question dietary dogma online, and you can bet it will lead to a highly heated debate where anger and indignation can easily descend into name calling and personal attacks.

jesus toastAnd even if you religiously avoid all cyber nutrition nuts, you may still be at risk. According to Freedhoff, although you may not have a stranger’s zealous scrutiny to watch out for, you’ve still got yourself. Dietary dogma, almost by definition, dictates blind faith and absolute loyalty, where breaking a dietary commandment is akin to committing a sin. And with sin, comes guilt. And if you feel guilt often enough, you might well decide to abandon your entire healthier-living, guilt-inducing effort.

Nutrition as religion demands perfection, yet perfection is an impossible goal. Remember, food is not simply fuel. Since the dawn of humankind, food has been used for comfort and celebration, and if your newly found dietary religion forbids foods you enjoy, my bet is you’re not long for that diet.

diet tapemeasureSo what’s the solution?  Freedhoff advises : the easiest question to evaluate any dietary plan or religion is simply, “Could I happily live like this for the rest of my life?” where the most important word in that question is “happily.” If the answer’s “No,” you’ve either got to get comfortable with adding in some sinning, or find another way to go.

Add in some sinning in the form of thoughtful, “worth-it,” dietary imperfections, and suddenly new lifestyles may transform from the merely tolerable to the actually enjoyable. Enjoy your lifestyle, albeit imperfectly, and maybe you’ll even stick with it.

Nutrition isn’t religion. Eat the healthiest diet that you can enjoy, because if you’re not enjoying it, it isn’t going to last, and tolerable isn’t good enough.

Go on, sin a little, on us. The good doctor will forgive you enough to forgive yourself.

In Vino Veritas?

GEICO camelHappy Hump Day!

While we may not be able to make you laugh quite as much as the GEICO camel, we do bring you news that should at least make you smile.

A new Spanish study suggests that drinking wine might help you avoid depression.

Although drinking a lot of wine or other alcohol may be a sign of depression or other mental health problems, alcohol in moderation may benefit mental health according to the study authors.

One drink a day, preferentially wine, may help prevent depression,” said lead researcher Dr. Miguel Martinez-Gonzalez, chair of the department of preventive medicine and public health at the University of Navarra, in Pamplona.

red-wine_0Researchers followed more than 5,500 light-to-moderate drinkers, aged between 55 and 80 for up to seven years.  None of the individuals had suffered from depression or had alcohol-related problems at the start of the study. Over seven years, with medical exams, interviews with dietitians and questionnaires, the researchers kept tabs on participants’ mental health and lifestyle.  Wine was the most popular drink and participants who drank two to seven glasses a week were the least likely to suffer from depression, compared to nondrinkers. These findings remained significant even after the researchers took factors such as smoking, diet and marriage into account.

But before you start reaching for the corkscrew, we need to warn you that not all experts agree with the findings and even the research team, only saw benefit in moderate drinkers.

Martinez-Gonzalez thinks the apparent benefit of wine in preventing depression may work the same way that moderate drinking helps prevent heart disease.

Depression and heart disease seem to share some common mechanisms because they share many similar protective factors and risk factors,” he said. However, he added that depression prevention is not a reason to start drinking.

If you are not a drinker, please don’t start drinking,” he said. “If you drink alcohol, please keep it in the range of one or less drinks a day and consider drinking wine instead of other alcoholic beverages.”

Tony Tang, an adjunct psychology professor at Northwestern University, in Evanston, Ill., said the new research “is consistent with other studies suggesting modest health benefits of very modest drinking.”

red wine glassesBut, Tang said other factors may be at work in the potential connection between wine and depression. He noted that compared to nondrinkers, those in the Spanish study who drank a moderate amount of wine were more likely to be married men who were also physically active.  Being single or divorced, living alone and being sedentary are well-established risk factors of depression. Thus, he suggests, the correlation between modest drinking and depression is a coincidence caused by these other known factors.

An adequate social life is the most important factor we know that protects people from depression,” Tang said. “Perhaps not drinking is a sign of serious social isolation in Spain while drinking a glass of wine a day is simply a sign of having a normal social life.”
