TAG | Cognitive Function
From piling on wrinkle creams to dying those nagging grays, it seems Americans are obsessed with preserving youth, but what about age-proofing your brain? New science reveals a smarter way to keep the brain young; fish oil. According to a new study published in the journalNeurology, diets lacking in omega-3, the essential fat found in fish oil, could lead to memory loss and dementia and cause the brain to age faster.

In addition to supporting brain health and cognitive function, the main omega 3 fats found in fish, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), have also been shown to support a healthy mood, normal inflammatory response in the body, immune health, eye health and heart health.
Wondering how much to supplement? As Dr. Snyderman points out in the video above, current national guidelines suggest at least 2 servings of fatty fish per week or a minimum of 500 mg combined EPA/DHA per day. However, some people, like those with heart disease or other health issues, may need to take up to double that dose.
If you’re thinking it might be tough to fit fatty fish into your weekly meal plan, you’re not alone. Whether it’s personal taste, limited availability or the increasing concern about the high levels of mercury in fish, many people are much happier getting the benefits of omega 3 fats in one convenient softgel rather than head to the fish counter at the grocery store. Just be sure that you choose a high quality fish oil that offers high concentrations of EPA and DHA, and has been purified to remove contaminants and is third-party tested for freshness.
An unexpected toxin was recently found to have a strong association with intellectual ability in children — manganese. Where is this manganese coming from? Surprisingly, from tap water that contains manganese concentrations below the current guidelines for safety. Kids with the most exposure to manganese through tap water were found to have lower IQs than those children who were not exposed.
Workplace manganese exposure has been known to have neurotoxic effect, but this is the first study to look at lower concentrations of manganese from drinking water and food sources and its effects on cognitive function.
Manganese is a naturally occurring toxin found in soils in certain regions, which can then leach into groundwater sources. This is especially true in parts of Canada where this study took place. Hopefully more studies will be done and awareness will be raised about filtering this toxic element out of our drinking water.
