Mind your brain, keep it active

Dr Shikha Sharma

Keeping the mind active and the brain healthy is one of the most important aspects of health in the older years of your life. Body degeneration is an active and constant process, but then the body also works just as actively and constantly to regenerate. This also applies to the brain. However, if the brain does not get the raw materials it requires, the regenerative process suffers.

There are certain things that the brain requires to stay healthy:

1. Brain-specific nutrition: The brain is literally made of ‘good’ fats – a lot of its nerve coverings are manufactured from good fats and oils. Physically, brain development is very rapid from the moment of birth to the age of two years. So a baby needs lots of good fats to ensure that it has the necessary supply of essential oils for brain development.

wellnessGood fats are also responsible for neurons and the entire nervous system. Good fats include unprocessed, unrefined oils from nuts and oil seeds. Seeds are a treasure trove of healthy minerals, B vitamins and folic acid. They are a naturally rich source of iron and zinc, and are also good sources of healthy protein.

Sesame seeds are an excellent source of calcium – particularly important during adolescence, childbirth and menopause. All seeds are a source of vitamin E. So eat almonds, walnuts, pine nuts, chilgoza, hazel nuts and pistachios. Add sunflower and flax seeds to the mix. Unhealthy oils and fats are transfats, over-processed and refined fats, deep fried and refried oils, adulterated oils and excess saturated fats.

Antioxidants are very important for the brain. This is because the brain is susceptible to tissue problems due to its high level of work and regeneration. Antioxidants ensure that the brain has enough cleansing and detoxifying agents to keep it clean and healthy. Good antioxidants for the brain are organic fruits and fresh vegetables, green tea (without milk and sugar) and some herbs.

Good proteins are just as important for brain development. These include sprouts of organic dals like mung, channa, lobhia, moth and so on. Tofu, soya milk and organic lean fish are good sources too. The brain requires a lot of carbs to function effectively. Starving makes the brain dull, but be warned – so does gluttony. Good carbs are fruits, dry fruits like dates, figs and raisins, whole grains like dalia, oats (not the instant variety), unpolished rice, barley, whole corn and millets.

2. Herbs that facilitate brain regeneration: These include yastimadhu (liquorice or licorice), guduchi, shankhapushpi, mandukaparni, chitrak root, brahmi, vacha, haritaki, kustha and shatavari.

3. Oxygen: Oxygen is vital for brain health. Aerobic exercise, pranayams, dancing, active playing… all of these contribute to lung expansion, thus ensuring that oxygen reaches the brain.

Nuts4. Mental exercise: Challenging, enjoyable problem-solving puzzles, learning new languages, learning a new skills… all this creates a very healthy and active brain.

5. Physical exercise: Physical exercise promotes blood circulation to the brain and helps the regenerative process.

6. The moderation of certain lifestyle hazards: Food and alcohol addictions, lack of sleep, too much anxiety, nicotine, over-medication and a sedentary lifestyle make us dull.

Brain health is a combination of all the factors above. Keeping your brain healthy also promotes overall health.

Know your brain
1. Your brain forms 2 per cent of your total body weight but uses 20 per cent of your body’s energy – enough to light a 25-watt bulb.
2. The brain uses glucose as fuel. When you work late, eat fruits and dried fruits like raisins, prunes, dates and apricots. They provide healthy sugar and minerals.
3. Alcohol weakens connections between neurons. Take multivitamins and detox the liver frequently if you drink alcohol regularly.
4. The brain produces 70,000 thoughts a day on an average.
5. Humans make new neurons throughout their lives in response to mental activity. So join hobby classes or a social welfare activity.
6. A study of one million students showed that students who ate lunches that did not include artificial flavours, preservatives and colours did 14 per cent better on IQ tests than students who ate lunches with these additives.

Antioxidants and Brain Health

by: Dr. Paul Gross

Your brain is your greatest asset but it is also your body’s most vulnerable organ. It requires constant support from other major organs and is your most susceptible organ to oxidative stress during aging.

Here are some brain facts:

1. Your brain makes up only 2% of your total body weight but requires 20% of your heart’s output of blood to sustain the amount of oxygen that it needs.

2. Your brain is the most oxygen-demanding organ in your body.

3. Your brain uses chemicals (neurotransmitters) to relay important messages to other parts of your body. These same chemicals are also involved in chemical reactions that produce damaging free radicals.

4. If your brain cells become weak or die they cannot repair themselves. Their functions then can be permanently lost if cell death or damage occurs.

Given these susceptibilities, your brain is especially vulnerable to conditions that threaten oxygen supply, such as in head injury, stroke, lung diseases and heart failure. Under these conditions, brain activity will continue even without enough oxygen. This can cause problems that lead to extreme levels of oxidative stress and the over-production of damaging free radicals.

In diseases like Alzheimer’s and Parkinson’s, other damaging factors are at work. In Alzheimer’s disease, a toxic protein called beta-amyloid, forms in your brain tissue. This protein acts as an irritant and causes inflammation in your brain. This inflammation then causes the production of free radicals that can destroy any membranes and cells in their path.

Parkinson’s disease results from unregulated production of the brain chemical dopamine which, with the help of free radicals, becomes toxic to the brain cells that control your motor functions.

Even in a healthy brain, oxygen radicals are produced every moment during normal high-oxygen demand of neuronal activity. In a healthy brain, enzymes and nutritional antioxidants neutralize these radicals.

Benefits of Dietary Antioxidants

What safeguards can healthy people take to reduce risk of diseases and especially to protect their brains from oxidative stress over a lifetime?

The simplest answer is to follow a diet that includes abundant sources of antioxidant chemicals derived from plant foods. Evidence for the benefits of such a dietary regimen has only been demonstrated in experiments with animals up until now, but the results are convincing. Over the past eight years, the research activities of Dr. Jim Joseph of the US Department of Agriculture, Boston, have focused on how to protect the brain from oxidative stress with dietary use of antioxidant-rich plants such as strawberries, cranberries, elderberries, blueberries and spinach.

Dr. Joseph’s research findings—a message closely pertinent to this essay—can best be represented by a quote from one of his research reports in 1998: “increased antioxidant protection through diets comprised of fruits and vegetables identified as being high in total antioxidant activity might prevent or reverse the deleterious effects of oxidative stress on neurons.”

Summary: Oxidative stress is a major factor in brain aging. This stress can be combated or balanced by including dietary antioxidants into your daily life. The best way to do this is by eating lots of colorful fruits and vegetables each day.
