Our Antioxidant System, Protein & Brain Function

Our Antioxidant System, Protein & Brain Function Knowing the right food to eat–or not to eat is not a gift–it's a process you work towards every day. It is a wealth of knowledge, the ultimate tool to shape your life every day, to empower and create a dynamic well-being. In a very simple and profound way what we eat affects our appearance, thought, emotion, lifestyle, health and our planet. Food can quicken the brain and lift the mood. Food can infuse our brains with spurts of electrical energy that make us think faster and perform better. Much of the credit for discovery of how food can manipulate the brain activity goes to Neuroendocrinologist Richard Wurtman and colleagues at the Massachusetts Institute of Technology in Cambridge. According to their pioneering research the secret is in Neurotransmitters. These Neurotransmitters are manufactured by nerve cells using specific food components called precursors as raw material. Food helps create various Neurotransmitters with different functions depending on the type of raw material supplied by a specific food. An example is tryptophan, an amino in protein foods that is made into serotonin, the calming chemical that makes you relaxed and drowsy. From tyrosine, an amino, are born dopamine and norepinephrine, neurotransmitters that enliven the brain making you more alert and mentally energetic. Brain chemistry is extremely complex because amino acids, varying in size and concentration in the blood, compete for entry into the brain. 1. What are the key factors to fine tuning your diet and listening to your body? Protein–protein containing foods are uppers when you want to stay mentally sharp. Do not reach for candy, cake, donuts, ice cream, rice, or pasta. Bonnie Spring, a professor of Psychology at the University of Health Science at Chicago Medical School, and Food and Mood researchers explain that protein simply keeps the carbos from making you fuzzy-headed. Spring says studies show that including 5%-10% protein in a meal helps block the build-up of serotonin in the brain. Dr. Barry Spears, creator of "The Zone Diet" and William Wolcott of "The Metabolic Diet" share some of the same beliefs, based on clinical nutrition. 2. Brainpower and Smart Foods What you eat could have a profound effect on how you think, your intelligence level, and your memory. For example, what you eat affects the following: The level of nerve chemicals in the brain that regulate all mental processes The development and maintenance of brain cell function and structure The insulating sheath surrounding the nerve cells that speeds the transport of messages from one neuron to another The level of enzymes and their activity, which enhances brain function The amount of oxygen that reaches the brain The rate of accumulation and removal of cellular debris The ability of brain cells to transmit electrical messages Brain power fluctuates depending on what and when you eat. Your brain is an organ just like your heart or liver and it needs a constant optimal supply of nutrients to function at its best. If you're having trouble concentrating, staying motivated or just thinking clearly, take a good look at your breakfast habits. Skipping meals frequently will drain glucose reserves and force the brain to "run on fumes." The best way to enhance brainpower is to: Always eat breakfast Keep your meals small and frequent Combine a little protein with some carbohydrate whole food 3. Stress and Diet Stress and nutrition are closely intertwined. A nutritional deficiency is a stress to the body itself, a strain on all the metabolic processes. For example, a marginal iron deficiency results in reduced oxygen supply to the tissues and brain. In turn, the oxygen starved tissues leave a person feeling tired, irritable and unable to concentrate. Likewise, an inadequate intake of the B Vitamins stresses the cell's ability to convert carbohydrates and fats into energy. The lack of certain amounts of beta-carotene and Vitamin C weakens the body's antioxidant defenses, exposing the tissues to increased risk of damage and disease. In addition, how well your body is nourished prior to and during stressful events affects how well you handle the stress. A well-nourished person copes better than a poorly nourished one. 4. The Antioxidant Part One of the most exciting areas of nutritional research today is identification and investigation of compounds in plants that supply us with certain powerful antioxidants. One sure way of getting these in your diet is to eat from "The Rainbow Diet," that is to have your plate reflect many different colors. The good news is that the antioxidant nutrients help protect and maintain a well-functioning nervous system and brain (they also protect against premature aging). This system is only as good as the person's diet. When antioxidant intake is optimal throughout life, free radical damage is kept at bay, whereas a consistently poor diet, low in antioxidants weakens the body's defenses and allows free radicals to proceed unchecked. Brainpower Foods Rich in Antioxidants are: Quality proteins Fruits and nuts Non-toxic and non-polluted seafood Legumes Whole grains Dark green vegetables Chlorophyll foods (spirulina, chlorella, wheat grass) Fermented soyfoods Foods rich in carotenoids Foods rich in bio-flavonoids References: Healing with Whole Foods by Paul Pitchford The World's Oldest Health Plan by Kathleen O'Bannon Baldinger Food Your Miracle Medicine by Jean Carper Food & Mood by Dr. Elizabeth Somer Food and Healing by Annemarie Colbin Nourishing Wisdom by Marc David Metabolic Typing Diet by William L.
