Back in 1997, an epidemiological study found that increased fish consumption was linked to a lower risk of Alzheimer\u2019s Disease (1).<\/p>\n

Then in 2005, a pre-clinical study showed that a diet rich in the poly-unsaturated omega-3 fatty acids slowed the progression of Alzheimer\u2019s type brain pathology in an aged mouse model (2).<\/p>\n

Three years later, a relatively small clinical trial found that small doses of omega 3\u2019s led to some improvements in patients with mild cognitive impairment, although not with Alzheimer\u2019s Disease (3).<\/p>\n

All this boosted sales of fish oil supplements, and triggered another, larger trial headed by Joseph Quinn which was published in 2010 \u2013 with disappointing results. According to that study, daily supplements of docosahexaenoic acid (DHA), one of the two omega 3\u2019s in fish oil, did not reduce cognitive decline in patients with mild-to-moderate Alzheimer\u2019s disease (4,5).<\/p>\n

According to the researchers, \u201cThe hypothesis that DHA slows the progression of mild to moderate Alzheimer disease was not supported, so there is no basis for recommending DHA supplementation.\u201d\u00a0<\/em><\/p>\n

Here is a prime example of research using concepts and trial designs more suited to testing drugs than nutritional interventions.<\/p>\n

The first self-evident truth is that Alzheimer\u2019s Disease (AD) is clearly avoidable<\/strong>; many individuals reach ripe old ages without any signs of cognitive decline, and although genes are important, they have only been identified in less than 10% of cases of this disease.<\/p>\n

The second self-evident truth is that the biochemical imbalances that have been identified in AD are far too many, and too complex, to be amenable to single, simple input solutions such as a single<\/span> DHA supplement<\/strong>.<\/p>\n

They are, however, amenable to diet, which contains thousands of different compounds, many of which are known to interact with brain chemistry.<\/p>\n

The protective Mediterranean Diet<\/strong><\/h4>\n

At Columbia University, Professor Nicholas Scarmeas has been studying the relationship between diet and AD for many years. He has published a series of papers that show, unequivocally, that the risk of developing this cruel disease is diminished by consuming a Mediterranean diet (6).<\/p>\n

\"Fish<\/a>

This is a diet that contains high levels of a range of bioactive compounds, including the anti-inflammatory flavonoids<\/strong> \u2013 which are also strongly linked to a reduced risk of AD (7), and have plausible mechanisms of action (8, 9).<\/p>\n

The current anti-AD drugs are of limited use, and have a range of adverse effects. If you want to protect yourself or a loved one against AD, the logical way forward is not drugs, or pharma-style single compound supplements, but by dietary improvement supported by a comprehensive, broad spectrum micro- and phyto-nutritional support programme<\/span>.<\/p>\n

Nutritional support<\/h4>\n

The programme should contain omega 3\u2019s<\/strong>, which after all play a key role in neuronal defence mechanisms (10); but they must<\/span> also contain flavonoids<\/strong> and a wide range of anti-oxidants<\/strong>. This is critical; omega 3 supplements taken alone, without anti-oxidants, are oxidised in the body producing toxic and pro-inflammatory lipid oxidation products which shorten life span in pre-clinical models (11); and exacerbate AD (12)!<\/p>\n

No wonder the big Quinn trial failed. When the researchers must have known, from the National Health and Nutrition Examination Survey (NHANES), that their patients were suffering from dysnutrition and poor anti-oxidant status, why did these so-called experts design such a bad trial?<\/p>\n

Conclusion:<\/strong> Mono-supplementation with single nutrients is not going to lead to better health. Only a comprehensive combination of natural compounds, reproducing the elements of an ideal Mediterranean-style diet, can be expected to support long-term health and longevity.<\/p>\n
