How Nutrishield helps support Cognitive Health
Dementia is perhaps the most feared of the age-related diseases. In this – as all illnesses – early action is very definitely the best defence.
The brain is a fatty organ and metabolically very active. Which means it is vulnerable to oxidation – free radical damage to the fats that form the sheath protecting brain neurons.
So the anti-oxidants in NutriShield are important defences – and include vitamins C, D3 and E and zinc, and the phyto-nutrients in green tea, grapeseed extract2 and curcumin1.
These nutrients also powerfully reduce inflammation which we know is a major factor in Alzheimer’s3. Indeed, the MIND diet created by Rush University in USA is rich in exactly this type of phytonutrients and has been shown to reduce the risk of Alzheimer’s by over 50%.
You also need a supply of quality fatty acids in your diet to build the membranes around your brain cells - which is why Omega 3 is important to brain health5.
You also need to ensure that arteries are functioning well to supply enough oxygen to the brain – so the advice in How NutriShield Supports a Healthy Heart is important - because strokes and high blood pressure are triggers for dementia and Alzheimer’s. That’s why curcumin and betaine are so important for cognitive health as well as cardio-health.
Brain ‘plaques’ and ‘tangles’
Alzheimer’s brains are characterised by ‘plaques’ and ‘tangles’. Plaques consist of dead brain cells and a protein called beta amyloid which is toxic. Tangles are made up of another protein called tau, which becomes abnormal, and clumps together leading to neuron cell death and inhibited neural communication.
The science on Alzheimer’s is still evolving, but nutrients that may help prevent the development of these plaques and tangles include carotenoids like beta carotene, lycopene and lutein6 and, again, curcumin. An important article in the Journal Science Direct6 summarised them as “exemplary neuroprotection”
Nutrishield includes all these nutrients to support long-term cognitive health. There is a genetic factor in Alzheimer’s and dementia (linked to a gene called APOE). But there is a lot you can do to reduce the risk – including staying physically active, engaging in mentally challenging tasks and being social.
