Fish high in omega-3 oils provide a rich source of the fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). DHA is a physiologically-essential nutrient in the brain and retina where it is found in high concentrations. For this reason fish oil rich in DHA is particularly beneficial for the eyes and brain. EPA is especially helpful for reducing inflammation. Together, EPA and DHA have been found to be helpful in a host of health conditions.

Recently, a couple studies have been published highlighting the visual benefits of fish oil. In one study involving 38,022 women, regular consumption of the omega-3 fatty acids EPA and DHA found in fish was associated with lower risk of developing age-related macular degeneration, which is a condition in older people that gradually destroys central sharp vision. Women who regularly consumed fish had a 42 percent lower risk.

The second study evaluated the way that omega-3 fatty acids work. The study found an effect that promotes healthy blood vessel growth while inhibiting abnormal blood vessel growth. Both retinopathy and macular degeneration involve abnormal blood vessel growth. Researchers isolated the compound which exhibited this effect—a metabolite of the omega-3 DHA.

Currently, an ongoing study through the National Eye Institute is underway looking at the benefits of fish oil supplements in people with age-related macular degeneration, and another study in Sweden is investigating the effects of omega-3 supplementation in premature infants who are deficient in omega-3 to determine if the supplement reduces the development of retinopathy. If so, this will lead to more studies.

The science behind EPA and DHA from fish oil span a wide range of health conditions, which highlights the importance of these oils for the body’s optimal function.

Anxiety, or worry, is experienced by just about everyone at some point. Some people have anxiety disorders, which are more serious conditions, but it’s safe to say that most people experience at least occasional anxiety. That’s why a new study on omega-3s found in fish oil is so exciting. It’s the first study to look at the effects of fish oil on anxiety in a healthy population—meaning, in people who don’t already have an anxiety disorder. It’s already known that fish oil can be helpful for those people. But what about people who only experience anxiety here and there?

The researchers took a group of medical students and gave them omega-3 supplements for three months. The supplements contained 2,085 mg of EPA and 348 mg of DHA. Another group got a placebo. After three months, the group taking the fish oil showed a 20 percent reduction in anxiety scores and a 14 percent reduction in the production of the inflammatory marker interleukin-6 (IL-6) over the placebo group.

IL-6 is an inflammatory cytokine. Depression and anxiety are both known to involve the production of inflammatory cytokines. This is one of the gut-brain connections, actually, since the inflammation can originate in the gut. Omega-3s were able to reduce these inflammatory compounds, highlighting just one way they may be helping mood disorders like depression and anxiety.

This week, if you tend to get anxious about things, even if occasionally, and you’re not taking fish oil, you might want to reconsider. The studies on fish oil are hard to ignore.

A study published back in May was the first to show that the Bt toxin from genetically modified corn enters the bloodstream. The study involved 30 pregnant women and 39 non-pregnant Canadian women, and found the toxin in 93 percent of the pregnant women, in 80 percent of the umbilical cord blood of their babies, and in 67 percent of the non-pregnant women.

The researchers suggest that the toxins entered the bloodstream by way of the consumption of meat from animals fed Bt corn. Certainly dairy from animals fed Bt corn, or even corn products made of Bt corn, could also be sources of the toxin. Fully 88 percent of the corn planted in the U.S. is genetically engineered. Much of this is used as animal feed, though genetically modified corn ingredients can also be found in a vast array of processed foods.

There is currently a movement to pass legislation that would require labeling of genetically modified foods. Visit the website for the Institute for Responsible Technology to sign a petition, and to see video segments from the Dr. Oz show on this topic.

When it comes to genetically engineered foods, one major fear has been that genetically modified plants could spread to the wild. Another recent study, published in the online journal PLoS ONE, has found that this is now a reality. Large populations of genetically engineered canola have been found outside of cultivation areas, and are capable of hybridizing with each other, creating yet new combinations of transgenic traits.

This week, if you think that genetically modified foods should be labeled, sign the petition here.

Many of the foods we eat, and the ways in which we eat those foods, are the result of formed habits—that is, when you eat a certain snack at a certain time (say, chips in the afternoon); or when you eat a particular dessert each night in front of the television; or even when you choose a healthy salad with lean protein every time you eat at a certain restaurant; you are indulging a habit. As you can see, not all habits are bad. That’s good news.

A recent study looked at how our environment can have an impact on eating habits. Researchers from the University of Southern California gave movie-goers either fresh or week-old popcorn upon entering the theatre. Those people who usually ate popcorn during movies ate the same amount of stale popcorn as those who ate fresh popcorn, indicating that food habits, and the environment in which these habits take place, have a big impact on how and what we eat.

In another experiment, movie-goers were asked to eat popcorn with their non-dominant hand. So, right-handed people ate with their left hands and vice versa. Doing this caused people to pay more attention to what they were eating, and so they ate less. Coincidentally, using your non-dominant hand to do anything (say, brush your teeth) helps create new connections in your brain as it tries to grasp a new way of doing things. These types of brain hemisphere-crossing activities are actually recommended to stave off Alzheimer’s.

So, this week, take note of your eating habits—especially the bad ones. Then, try to change something about those habits. Maybe you change the scenery. Maybe you switch to a healthy food (creating a good habit). Or maybe you try to eat with your other hand to reduce the likelihood of overdoing it. See how many bad habits you can turn into good habits!

It’s Monday again. Let’s start this week off right!

A recent study published in the Journal of Neuroscience performed a range of tests to analyze the effect of thinking about the healthiness and tastiness of foods when making the decision about which foods to eat. As it turns out, people who thought about the healthiness of the food choices when making a decision about what to eat chose healthier options, even if the food wasn’t perceived as tasty. When the food was also perceived as tasty, they always chose it.

So, this week make it a practice to consider the healthiness of the foods you choose. Before planning dinner, take a moment to think about how healthy the meal is. At the grocery store, shop the perimeter (where the healthiest foods are) and think about your selections as you shop. At snack time (especially) think twice before you ignore the call of healthiness.

The far-reaching effects of gluten sensitivity and celiac disease never cease to amaze me. So many conditions outside the gut are triggered by a reaction against gluten inside the gut. A recent study has brought to light one lesser-known effect of celiac disease—infertility.

It has been known for some time now that infertility and recurrent spontaneous abortion is more common among women with celiac disease. And about 4 percent of infertile women have celiac disease!  I wonder how many more of these women may have silent celiac disease or even gluten sensitivity? A large proportion of people with celiac disease are undiagnosed.

A recent study has looked a little closer at infertility and early pregnancy loss, and determined just how this may happen. It turns out that anti-tissue transglutaminase antibodies (which are antibodies that the immune system makes against gliadin, the gluten protein) bind to the developing placental lining. This can interfere with proper development of the placenta and fetus.

It is already known that these anti-tTG antibodies can attack other tissues in the body, like the thyroid, pancreatic beta cells or even brain cells. This phenomenon is known as autoimmunity. This study highlights yet one more way in which anti-gliadin antibodies can harm areas of the body that are not in the gut. And it strengthens the evidence that following a gluten free diet can benefit the entire body.

If you suspect you are gluten sensitive, you may want to be tested or try an elimination diet for a few months to see if it helps you.

In this time of scary bacterial infections, antibacterial soap would seem a regular sink-side bottle. We are told that germs are bad—and many are—and that we need to scrub them away with antibacterial soaps, scrubs and sprays. Right? Well, not completely. Handwashing for at least 15 seconds with hot soapy water is very effective at removing germs. All that is needed for this is regular old soap.

Antibacterial soap contains a chemical called triclosan (2,4,4’-trichloro-2’-hydroxydiphenyl ether). This chemical has been said to contribute to the increase in antibiotic resistant bacteria. This is because it’s in so many products and pollutes waterways, increasing its exposure to bacteria, which then become resistant.

Dr. Smith blogged in December about the link between use of triclosan and the development of hay fever and allergies in children and teens. Now comes another study published in Environmental Health Perspectives that adds to the last—children and adolescents under age 18 with the highest levels of triclosan in their urine were more likely to be diagnosed with allergies and asthma.

The head researchers stated, “Our results suggest that exposure to triclosan, particularly at times during the life course when the immune system is developing, may modify immunologic response.” They are not quite sure how that works, but suggest that applying triclosan soaps to the skin may reduce some types of microbiota on the skin, or even in the bowels. Or, the soaps may directly affect the endocrine system, which is in close communication with the immune system.

While they work out the details, I say steer clear of antibacterial soaps. Just be sure to wash your hands well. It’s enough!

A recent study published in the journal Environmental Health Perspectives and based on the National Health and Nutrition Examination Survey (NHANES) investigated the exposure of pregnant women to 163 chemicals, revealing, “ubiquitous exposure to multiple chemicals during a sensitive period of development.” The study found that pregnant women were even exposed to chemicals banned decades ago, and some of the chemicals analyzed were found in 99 – 100 percent of the women.

Health effects were not assessed in this study, but many of the chemicals found are known to have detrimental consequences on health. In another case study of one women with particularly high levels of bisphenol A (BPA) during her 27^th week of pregnancy, the infant experienced neurobehavioral abnormalities at his one-month study visit. Researchers of this study were able to trace her abnormally high BPA exposure to the high consumption of canned foods, heating of plastic food containers, and use of plastic cups. The week of her highest recorded BPA level, she consumed canned ravioli each day. It is known that acidic foods can bring out more BPA from can lining, and canned tomato foods have been found to be higher in BPA.

BPA and phthalate exposure can be reduced by purchasing fresh unpackaged foods and avoiding plastic food packaging, storage containers and utensils. In one study, again published in Environmental Health Perspectives, consuming fresh foods prepared and consumed without the use of plastic was associated with a 66 percent reduction in the amount of BPA in urine.

We can’t eliminate all toxins, but there are small things we can do try to reduce them. Replace your plastic Tupperware with glass containers. Don’t use plastic wrap and try to prepare as much food as you can from fresh, unpackaged foods. And never heat food or drink in plastic. Do what you can and know that you are at least doing something. Spread the word—pass this information on.

 Constipation is a common childhood condition, unfortunately. Even worse is the mainstream definition of constipation—less than three bowel movements per week. Say what! If you or little Johnny are only pooping three times a week, we’ve got a problem. Regular elimination helps remove toxins from the system. And the longer feces sit in the colon the more toxic it gets!

A recent study evaluated the effect of the probiotic Bifidobacterium breve in children with constipation. Twenty children between the ages of 3 and 16 took the probiotic daily for a 4-week period. Bowel movement frequency and stool consistency improved significantly in these children. That means their constipation improved. The results of this pilot trial are promising, and will lead to a larger randomized controlled trial.  

Bifidobacteria are the most prevalent probiotic bacteria in the large intestine, or colon, of children. Normal bifidobacteria colonization occurs when babies are born vaginally, and is improved during breastfeeding. Antibiotic treatment can interfere with colonization, especially during the first months and years of life. Maintaining a healthy balance of bifidobacteria is associated with intestinal health, which is the foundation of total body health.

The Standard American Diet (aptly named SAD), also known as the Western diet, is full of processed and fried foods, refined carbohydrates and sugars, and saturated and trans fats. It is low in fiber, fruits and vegetables, whole grains, lean proteins and beneficial fats (like omega-3s).

This diet has been blamed (and rightfully so) for so many different health conditions, most notably, heart disease and diabetes. But cheer up! A change in diet and increase in exercise can reverse both these conditions. 

Another recent study links another condition to SAD. Attention-deficit hyperactivity disorder (ADHC, or as it used to be known ADD) is one of the most common childhood disorders, and may continue into adulthood. It involves difficulty staying focused, difficulty controlling behavior and hyperactivity. In adolescents, consumption of a Standard American Diet was found to more than double the risk of being diagnosed with ADHD when compared to a diet low in the foods found in the SAD diet.

The suggested reasons for this difference were:

• SAD diet has a less optimal fatty acid profile (too much omega-6 and not enough omega-3)
• SAD diet may not provide essential micronutrients needed for brain function
• SAD diet contains more artificial colors, flavors and additives linked to ADHD symptoms

More studies need to be done to figure out which came first, but I simply can’t wait that long to get the word out about how detrimental the SAD diet is to our children’s health. I know that children and adolescents are picky eaters, but it is essential that they get all the nutrients they need for the best start in life – one that will carry them through the years. The earlier they begin eating well, the more likely they will eat that way for life.
