Omega 3 & Alzheimers

A major scientific report has revealed that omega 3 could combat the onset of Alzheimer’s and dementia. For anyone with a regular portion of fish in their diet or omega 3 supplements in their nutritional regimen, you’re already fighting the good fight.

The research revealed that eating fish once or twice a week is highly effective, with seafood prolonging your mental function by boosting the blood flow to your brain. The study adds to past evidence that oily fish can battle conditions like Alzheimer’s.

Another survey revealed that dementia is among many people’s greatest fear. Around 850,000 people living with the cruel brain disease in Britain.

American scientists claim polyunsaturated fatty acids improve the amount of blood in areas of the brain that are key for memory and learning.

The study saw participants divided into two groups, each consuming high or low levels of omega-3. Scans were then carried out on 128 regions of the brain with each volunteer carrying out tests to measure mental skills.

Professor Daniel Amen, of Amen Clinics in Costa Mesa, California, said: “This is very important research because it shows a correlation between lower omega-3 fatty acid levels and reduced brain blood flow to regions important for learning, memory, depression and dementia.”

What Is Omega 3?

Omega 3 is an essential fatty acid sourced from fish oil, which is rich in EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). The human body is able to turn ALA into usable DHA and EPA to some degree, but this isn’t as efficient as getting DHA and EPA directly from food sources that provide it. It’s one reason why nutrition experts recommend consuming wild-caught fish several times per week since many kinds of seafood are naturally high in DHA and EPA.

Humans are incapable of synthesising omega 3 and so it is essential that you consume them through food sources.
The study suggests that just a few dietary changes can have a considerable, lasting effect on your brain function and health.

Health Benefits of Omega 3

Omega 3 Deficiency

Previous studies have drawn links between diets that are high in omega 3 and a lower risk of dementia, with Mediterranean cuisines coming highly recommended for good health with their servings of fish and olive oil.

The highest ranking fish for omega-3 content, in order from the most, is mackerel, salmon, cod liver oil, herring, tuna, white fish, sardines and anchovies.

If you’re looking for new ways to get omega-3 into your diet, as well as for your supper you could start opting for salmon, mackerel or kippers for your breakfast along with egg yolks.

Many dairies, meat and poultry products now incorporate higher levels of omega-3s as it is added to animal feed.

As well as oily fish, there are many other food sources for your recommended dose of omega 3. Worry not, vegetarians. Walnuts, chia seeds, flaxseeds, hemp seeds, natto and egg yolks are also high in omega-3 content.
Other risks of an omega-3 deficiency include inflammation, a higher risk of heart disease, high cholesterol, allergies, joint and muscle pain, digestive disorders and depression.
