Omega-3 and Omega-6 Fatty Acids Improve Reading Skills in Healthy Children

reading

Previous research has shown positive effects of essential fatty acids (omega-3/6) in children with attention and reading difficulties. New research shows that these fats could improve reading ability in mainstream schoolchildren.

Foods high in omega-3 include fish, vegetable oils, nuts, flax seeds, and leafy vegetables. Most omega-6 fatty acids in the diet are obtained from vegetable oils. The modern diet is particularly low in omega-3 fatty acids which are important for signal transmission between nerve cells and the regulation of signaling systems in the brain.

The study group included 154 schoolchildren from western Sweden who were in grade 3 (between 9 and 10 years of age). The researchers then measured their reading skills using a computer-based test, called the Logos test. It measured reading speed, ability to read nonsense words, and vocabulary.

The children were randomly assigned supplements with omega-3/omega-6 or a placebo of palm oil which they took for 3 months (3 capsules per day). The study was double-blinded so neither the researchers nor parents knew which treatment the children were taking. After 3 months all the children received the real omega-3/6 capsules for the remainder of the research study.

Researchers saw a significant improvement in reading skills after the first 3 months in children taking the omega-3/6 acid compared to the placebo. While no children diagnosed with ADD/ADHD were included in the study, those children with mild attention problems achieved greater improvements in certain tests, such as faster reading, after taking the real supplements.

All About Hormones: How they Function to Keep You Healthy

If your circulatory system is a superhighway, your hormones are some of the most important traffic traveling those critical thoroughfares. Likening hormones to cars shows these complex molecules as simply vehicles. And that’s exactly what they are. Hormones are constantly driving through your internal highways to transport messages and signals between your body systems and organs. For example, when you’ve eaten a meal, the hormone insulin enters the highway from the pancreas. Then it races through the bloodstream to collect glucose and deliver it to your cells for energy. Let’s broaden this driving metaphor. If hormones are various vehicles, then the glands that produce them are like car manufacturers. These manufacturers are all a part of the larger controlling body—your endocrine system. The endocrine system employs vehicle (or hormone) manufacturers throughout the body: the pancreas, thyroid, adrenal, ovaries, and testes to name a few. Let’s take a closer look at the major hor...

Foods That Fuel You: Understanding the Glycemic Index

You want to eat right and don’t know where to start. So, you find yourself surfing the web for examples of “good” and “bad” foods. A list of healthy options is essential for paving the road to a healthy diet. But lists do little to educate you on why good foods are, in fact, good for you. You can pick better ingredients for healthier meals if you understand how the food you eat creates usable energy in your body . The glycemic index can be just the tool you need to build a better understanding of how food works in your body. You already know that the food you eat becomes energy. But learning how to use the glycemic index can illuminate just how much energy you can derive from certain foods. It can also teach you about the quality and dependability of that energy. Glucose—Derived from Food to Fuel the Body The energy currency for your body is glucose. This simple sugar is an abundant carbohydrate in your diet. Not all of the carbohydrates you consume are in th...

The 8 Pillars of Holistic Health and Wellness

Health is often understood as the absence of disease or sickness. While this definition is valid, it lacks the comprehensiveness of a broader approach. So start assessing your holistic health and wellness on a wider spectrum. This means wellness depends on more factors than simply avoiding the flu each year. Holistic health and wellness is sustained by eight pillars: physical, nutritional, emotional, social, spiritual, intellectual, financial, and environmental. The pillars will give you a sense of how to work toward your optimal wellness, but it’s by no means prescriptive. The path to wellness is not one-size-fits-all. The journey is unique and different for each individual. Your biology, personality, and environment will determine what wellness means to you. That’s why your approach should be personalized. The common thread for everyone is that wellness requires a holistic approach. So, let’s learn more about each pillar and how you can strengthen each one. Physical Most...
