Sales of Omega 3 supplements are growing faster than any other nutritional dietary supplement in history.

Lets examine exactly what Omega 3 supplements are and what they do.

DHA (docosahexaenoic acid) is one of the long chain polyunsaturated fatty acids known as essential fatty acids. It is, however, not the only essential fatty acid. Others include EPA (Eicosapentaenoic acid) and ALA (alpha-linolenic acid), and more. These are known as Omega 3 fatty acids.

They are known as essential fatty acids because scientists and health professionals who research our health consider them to be essential for the maintenance of good health, and to help prevent, or ameliorate a range of common health problems.

We have been brought up to believe that fats are bad for us. And in some cases this is true. For example saturated fat, most commonly found in animal products, is not good for our health. However it’s not true that all fat is bad for us and the Omega 3 fatty acids, particularly DHA and EPA, are considered essential to good health. They are polyunsaturated fatty acids.

Unlike some nutrients our bodies are unable to create DHA, or the other essential fatty acids, itself. Rather we must rely on dietary intake for our supply of these Omega-3 fatty acids.

Whilst in the past there was a range of sources of DHA in our diet these sources have reduced over the past hundred years. Fish oil from oily fish was the single biggest source of DHA in our diets, however during the last century the amount of fish in the average American diet has reduced dramatically.

However there are other sources of DHA as well. For example meat has been a good source of DHA and EPA in the past, however is now not so. This is because most of our meat is now sourced from grain fed animals, and grain fed beef is low in these Omega 3 essential fatty acids. Grass fed beef is much higher in Omega3 fats however grass fed beef is now relatively rare in our diets.

Over the last 30 years research has established clearly that adequate supplies of  DHA and EPA, the 2 most important of the omega 3 essential fatty acids, is essential to a wide range of health issues. Research has shown that the average American diet is inadequate in Omega 3 intake and increasing our intake can offer a wide range of health benefits including a reduction in heart disease, including fatal heart attacks, a reduction in the risk of stroke, a wide range of brain benefits including improved memory and brain function and a wide range of other improvements in our health.

However to make the statement that Omega 3 supplements are possibly one of the most important health measures of our generation might be drawing a long bow. Or is it?

A study published in April 2009 performed by a group of Harvard University researchers the study examined your likelihood of dying from one or other of a series of various lifestyle factors. Read the rest of this entry

If you’re not taking DHA supplements you should be.

One of the biggest breakthroughs that science has discovered in recent years in naturally improving your health is the role of DHA (and EPA) in so many aspects of our general health. Today we would like to examine exactly what DHA is, and why DHA is considered so important to many areas of health, including infant health.

DHA stands for Docosahexaenoic acid. It is what is known as a long chain fatty acid, or otherwise known as an essential fatty acid. DHA makes up a large proportion of the fats in our brain and is one of the most important fats in the development of the fetal brain.

Many people assume that eating fat is bad for you. This is far from the truth and there are a number of fats, known as essential fatty acids, that are in fact extremely important for your health. Evidence is that our diets are low in these fats, particularly in DHA, and that increasing our intake of essential fatty acids can have important positive impacts on so many areas of our health.

Certainly there is clear evidence that eating some kinds of fat is bad for you. Saturated fats for example, normally found in meat and dairy products, should only be consumed in smaller quantities than is now the case for most of us. However essential fatty acids have been found over and over again in studies to be very important to our health and our consumption of these should be increased.

The most important of these essential fatty acids is DHA, however EPA (Eicosapentaenoic acid) is also important. Neither of these fats is manufactured in our body and both must be taken from our food. Current science shows that the average American diet is largely deficient in both DHA and EPA.

Both of these fats are known as Omega 3 fatty acids. You may have heard of the benefits of Omega 3, this refers to the benefits of DHA and EPA. There are a number of sources of DHA and EPA but for our purposes they are primarily found in fish and in particular fish oil, and for various reasons are best taken as DHA supplements, in fact the best way is to take Omega 3 supplements which combines the 2.

Studies are showing significant health benefits, particularly for children, from increasing the intake of DHA specifically in certain circumstances, and suggest that low levels of DHA, (as well as arachidonic acid (AA), a polyunsaturated Omega 6 fatty acid), may well benefit young children with specific paediatric conditions including attention deficit hyperactivity disorder, cystic fibrosis, phenylketonuria, unipolar depression, aggressive hostility, and congenital metabolic disorders, amongst others.

The Omega 3 fat DHA is an unsaturated (healthy) form of fat. Other forms of fat, known as saturated fats, are not good for the health.

Lets consider in a little more detail the difference between saturated and unsaturated fats.

Probably the simplest way to differentiate between a saturated and an un-saturated fat is to consider the state of the substance at room temperature.

Saturated fats are fats which form a solid at normal room temperatures.

Think about the last time you cooked roast beef. If you left the resultant fat in the oven tray until the next morning it would be solid, and you could scrape it out. And yet when it came out of the oven it was liquid.

Saturated fats are found predominantly in animal products, including all meat.

Now think about some plant-based oils. Olive oil for example. Even if you cook with olive oil, at which time it will be liquid, it will remain as a liquid even at room temperature. It will be a liquid in the bottle in your cupboard right now.

Unsaturated fats are fats which remain a liquid at normal room temperatures.

Unsaturated fats are generally found in plants. They are also found in fish and other seafood. Read the rest of this entry
