You Are What You Eat.


Depending on what you want from your body, you must


put in it the right food. You need to pay special


attention to what you


eat. That’s right: Your shopping



list can help with your to-


do list. That’s because the


right foods are a kind of clean-burning fuel for your


body’s biggest energy hog


/pig:


Your brain.


A study in


the Journal of Physiology makes the point that, though


your brain represents only 2 percent of your body


weight, it makes 20 percent of the energy demands on


your

metabolism


/


food


/


energy


/


fuel.



Imagine your body is a car, if you only use your car on


the weekends then you will not have to put a lot of fuel


or oil into it, you will not have to replace the tiers very


often, the battery will last a longer, and so on. But if


you use your car fifteen hours a day then you will have


to put more fuel and oil into it and the tiers, battery,


lights, seats and engine will all wear- out quicker. If you


want to be an Athlete in the Olympics you will have to


eat the right foods to build your muscles and if you


want to be an Einstein you will have to put in different


foods to build your brain.



On


our new Eat This, Not That! Web site


, we rounded


up the best foods to munch/eat on when you need a


mental boost



and found studies that show, in fact,


that you can be up to


200 percent



more productive


if


you make the right eating choices. Stock up on these


items to, jog your memory, sharpen your senses,


improve your performance, activate your feel-good


hormones, and protect your quick-witted sharpness,


whether you’re 15, 40


years old.



WATER:



The Body’s


Most Important Nutrient.


Water is your body's most important nutrient, it is


involved in every bodily function, and makes up around


80% of your total body weight. Water helps you to


maintain body temperature,


helps


in digestion,


lubricates/oils


and cushions organs, transports nutrients,


and


flushes/wash-out


toxins from your body.


Everyone should drink at least 2 liters per day, and if


you exercise or are overweight, even more. Your


blood



is approximately 90% water and is responsible for


transporting nutrients and energy to muscles and for


taking waste from tissues.


Not enough of water will make a person get tired


quickly and have low concentration powers.





FOR SHORT-TERM MEMORY



Drink This!: COFFEE



Fresh-brewed coffee is the ultimate brain fuel. Caffeine


has been shown to


retard/slow


the aging process and


enhance short-term memory performance.


In one study, British researchers found that just one


cup of coffee helps improve attention and problem-


solving skills.



Naturally do not drink it before bedtime


and don’t drink


too much.



FOR LONG-TERM MEMORY



Eat This!: BLUEBERRIES



Antioxidants


in blueberries help protect the brain from


free-


radical damage and cut your risk of Alzheimer’s


and Parkinson’s diseases


when you get older. They


can also improve cognitive processing


(translation



thinking). Wild blueberries, if you can find them, have


even more brain- boosting antioxidants than the


cultivated variety.


Not That!: THE UNRIPE AND UNREADY



Here’s a cool tip: if your favorite berries are out of season,


buy them frozen. The freezer locks in peak flavor and


nutrients, so the


berries’ antioxidant capacity is maxed out.


Those pale, tough, and expensive off- season berries usually


ripen on a truck, rather than on the bush, so they’re


nutritional imposters compared to the real thing.





TO THINK FASTER



Eat This!: SALMON OR MACKEREL



So put salmon or mackerel on the grocery list. The


omega-3


fatty acids


found in fatty fishes are a primary/major building


block


of brain tissue, so they’ll


boost up your thinking power.


Salmon is also rich in niacin, which can help ward off


Alzheimer’s


disease and slow the rate of ageing.



Not That!: FULL-FAT ICE CREAM



Not all fats are created equal: Beware foods high in


saturated


fats


, which can clog blood vessels and prevent the flow of


nutrients and blood to the brain. Ice cream is not a brain-


health food.



TO ENERGIZE:



Eat This!: HIGH-PROTEIN SALAD WITH VINEGAR and


OLIVE OIL.



The oil in the dressing will help slow down digestion of


protein and carbohydrates in the salad, stabilizing blood-


sugar levels and keeping energy levels high. Build your


salad on a bed of green spinach for an added boost in


riboflavin, and add chicken and a hard- boiled egg for more


energizing protein.

the Eat This, Not That!


ultimate salad selector


.





TO CALM DOWN



Eat This!: LOW-FAT YOGURT OR MIXED NUTS



Yogurt and mixed nuts are some of the best food sources of


lysine; nuts pack loads of arginine which will make you alert


and quick thinking.



Not That!: SODA



A study from the American Journal of Public Health found


that people who drink 2? cans of soda daily are three times


more likely to be depressed and anxious, compared with


those who drink fewer. So Coca Cola is a Mental No No.



TO CONCENTRATE



Eat This!: PEPPERMINT TEA



The scent of peppermint helps you focus and boosts


performance, according to researchers. Need to reach


Chicago before nightfall, and you’r


e stuck in traffic around


Cleveland? One study found that peppermint makes drivers


more alert and less anxious.



Not That!: CANDY



Sugary foods incite sudden surges of glucose that, in the


long term, cause sugar highs and lows, leading to a fuzzy


state of


mind. So you’ll need to avoid all the attention


-


busting sugar bombs on this list of the


20 most sugar-


packed foods in America


.



FOR GOOD MOODS AND SMILES



Eat This! ARUGULA OR SPINACH SALAD



Leafy greens



arugula, chard, spinach



are rich sources of


B vitamins, which are key components on the assembly line


that manufactures feel-good hormones such as serotonin,


dopamine, and nor-epinephrine. According to a study


published in the Journal of Neuroscience Nursing, a lack of


B6


can cause nervousness, irritability, and even depression.



Not That!: WHITE CHOCOLATE



White chocolate isn’t chocolate at all, since it conta


ins no


cocoa solids. So it won’t stimulate the euphoria


-inducing


mood boosters like serotonin, as real chocolate does. Grab


the real thing, the


darker


the


better


. More cacao means


more happy chemicals and less sugar, which will eventually


pull you down


.



FOR SHARPER SENSES



Eat This!: 1 TBSP OF GROUND FLAXSEED DAILY



Flax is the best source of , or ALA





alpha linolenic


healthy


fat that improves the workings of the cerebral cortex, the


area of the brain that processes sensory information,


including that of pleasure. To meet your quota, sprinkle it on


salads or mix it into a smoothie or shake.
