EDIBLE IQ: Part 1

Forgotten what you did last week? Yesterday? These foods can help boost your brain power and charge up your memory.
Monday morning and the crew have gathered in the kitchen for coffee, shooting the breeze about the weekend’s misadventures. The circle gets to you. Wide stare. Nervous laugh. You can’t remember a thing about Friday night. There is much laughter – they think you were on a bender. But you know the truth. You were perfectly sober. You just can’t remember. Forgetfulness is unnerving, but it is not necessarily a symptom of early-onset Alzheimer’s disease.

The cumulative effect of environmental toxins and stress can also leave your brain tired and memory foggy, as can nutritional deficiencies: research shows that human brain continues to grow and develop throughout life. The better you feed it, the more efficiently it performs. According to Jean Carper, nutritional expert and the author of Your Miracle Brain, brains cells can malfunction because of damage caused by free radicals – unstable chemicals that are produced when oxygen is burnt to make energy for cells. The brain also needs specific nutrients to build neurotransmitters, explains Carper – nutrients you either give it or you don’t.

For example, the neurotransmitter acetylcholine, which is critical for memory, needs choline, which is concentrated in egg yolk. “The type of neurotransmitters your neurons make and release, and their ultimate destiny within the brain, depend greatly on what you eat,” says Carper. “When brain cells don’t get enough of the right nutrients, neurotransmitter systems can go awry, with disastrous consequences.” Our Stone-Age forefathers had the ideal diet: nuts, roots, berries, eggs, fish, and the occasional slice of free-range woolly mammoth. They must have had their problems, but it is safe to bet that memory loss was not one of them.

PILE ON THE ANTIOXIDANTS
Antioxidants, found in an army of fruits and vegetables, fight free radicals and reduce inflammation and oxidation in the cells. “Overwhelmingly, research shows that animals fed antioxidants over a lifetime have better mental abilities and live longer,” says Carper. “Loss of brainpower begins years before it is diagnosed and mainly results from gradual, undetectable hits on brain cells, hits that go unrepaired and lead to screw-ups in the brain’s circuitry, possibly neuronal death.” Denham Harman, MD, of the University of Nebraska, is the forefather of the free radical theory of ageing. He points to a critical age of 28 when antioxidant defenses decline significantly, making you vulnerable to age-related damage. So if you have not been conscientious in caring for your brain before then, it is definitely time to start.

BEST SOURCES: Berries (especially blueberries and strawberries) contain the phytochemicals anthocyanin and quercetin, which have been shown to reverse memory deficits in laboratory animals. Cruciferous vegetables (such as broccoli and cabbage); leafy greens (such as raw spinach and kale); prunes, raisins, garlic, avocado, oranges, red peppers, baked beans, and onions are all rich sources. Goji berries, which are low in sugar and high in antioxidants, are very good as well.
