Vitamins
HOW THEY WORK: A lot of people think vitamins can replace food, they cannot! In fact, vitamins cannot be assimilated without ingesting food. That is why they should be taken with a meal. Vitamins regulate metabolism, help convert fat and carbohydrates into energy, and assist in forming bone and tissue.
VITAMIN A (Beta Carotene)
A powerful anti-oxidant which helps protect the cells against cancer by neutralizing "Free Radicals," necessary for new cell growth; guards against heart disease and stroke; lowers cholesterol levels; slows the aging process; protects against colds, flu and infections of the kidneys, bladder, lungs and mucous membranes; promotes healthy wrinkle-free skin, and helps in the removal of age spots and acne; promotes healthy hair and nails; protects against air pollutants and counteracts night blindness and weak eye sight; builds resistance to infections; slows the progression of osteoarthritis and cataracts; helps prevent macular degeneration of the eyes.
VITAMIN B-1 (Thiamin)
Known as the "Morale Vitamin" because of its beneficial effects on the nervous system and mental attitude. It enhances circulation, assists in blood formation, carbohydrate metabolism and digestion; plays a key role in generating energy; promotes good muscle tone; acts as an anti-oxidant, protecting the body from degenerative effects of aging; helps prevent reoccurring canker sores; helps maintain a healthy nervous system; prevents depression, alleviates fatigue, optimizes brain function and mental alertness; has been used to treat numbness of the hands and feet, poor circulation, tingling sensations, weak or sore muscles, forgetfulness, heavy breathing, and irritability.
VITAMIN B-2 (Riboflavin)
Necessary for red blood cell formation, anti-body production, cell respiration, and growth; alleviates eye fatigue, and is important in the prevention of cataracts; aids in the metabolism of carbohydrates, fats and proteins; promotes the oxygenation of the skin, hair, and nails; eliminates dandruff; aids in the release of energy from food; reduces the occurrence of migraine headaches; helps eliminate cracked mouth, lips, and tongue; supports the production of adrenal hormones.
VITAMIN B-6 (Pyridoxine)
Can significantly reduce the risk of heart disease by inhibiting the formation of homocysteine, a toxic chemical that attacks the heart muscle and allows the deposition of cholesterol around the heart muscle; aids in maintaining the central nervous system and normal brain function; reduces muscle spasms, leg cramps and stiffness of the hands; relieves nausea and migraines, lowers cholesterol; improves vision, and aids in the prevention of PMS; promotes red blood cell formation; aids the immune system and antibody production; aids in cancer immunity and in the prevention of atherosclerosis; is destroyed by alcoholic beverages.
VITAMIN B-12 (Colbalamin)

PANTOTHENIC ACID
Is considered the "Anti-Stress" Vitamin because of its important role in the functioning of the adrenal glands, which produce hormones that help our bodies respond to stress; plays an important role in making hemoglobin, which transports oxygen throughout our bodies; helpful in detoxifying harmful chemicals such as herbicides and insecticides; along with anti-oxidants, zinc, copper, and vitamin D, will prevent accelerated joint degeneration, by encouraging your body's ability to regenerate cartilage; fights infections by building antibodies; prevents fatigue, and used by athletes to boost performance; used to reduce the adverse and toxic effects of many antibiotics; stimulates the release of energy from carbohydrates, fats and protein; promotes the production of red blood cells and sex hormones; helps with rheumatoid arthritis, osteoarthritis, and menopausal discomforts; lowers high cholesterol and triglycerides.
BIOTIN
Aids in the utilization of protein and other nutrients; aids in cell growth and fatty acid production; promotes the health of sweat glands, nerve tissue, bone marrow, male sex glands, blood cells, skin and hair; cures some forms of baldness, and is used in preventative treatments for baldness; prevents the hair from turning prematurely gray; alleviates eczema and dermatitis; alleviates muscle pain; may help reduce blood sugar levels in people with either type 1 or type 2 diabetes.
FOLIC ACID
May reduce the risk of a heart attack by lowering homocysteine levels. In recent years, high levels of homocysteine have been found to be associated with an increased risk of atherosclerosis (hardening of the arteries due to the accumulation of fatty plaques). Protects against birth defects by helping regulate embryonic and fetal nerve cell formation; protects against intestinal parasites and food poisoning; may delay graying hair when used in conjunction with pantothenic acid and PABA; promotes healthier looking skin, is considered a brain food; is needed for energy production, and the formation of red blood cells; strengthens the immune system by aiding the proper formation and functioning of white blood cells; important for healthy cell division and replication.
INOSITOL
Is vital for hair growth; promotes strong healthy hair, and aids in preventing fallout; high levels of this nutrient is found in the heart and brain; creates a calming effect and reduces blood cholesterol; prevents hardening of the arteries, and is important in the formation of lecithin and the metabolism of fat and cholesterol; removes fat from the liver; aids in redistribution of body fat; helps prevent eczema; has been used for depression, panic attacks and diabetes.
CHOLINE
A "super nutrient" for the liver and brain; needed for the proper transmission of nerve impulse from the brain through the central nervous system; is able to penetrate the blood-brain barrier and go directly into brain cells to produce acetylcholine, a chemical that aids memory; aids in the treatment of Alzheimer's and other age-related memory loss; aids in hormone production; is important in controlling fat and cholesterol build-up in the body; emulsifies (breaks down) cholesterol so that it doesn't settle on artery walls or in the gallbladder; used for the prevention and treatment of atherosclerosis and the metabolism of homocysteine; helps eliminate poisons and drugs from your system by aiding the liver; used to treat liver damage caused by alcoholism.
PABA (Para Amino Benzoic Acid)
An anti-oxidant which helps in the formation of red blood cells; aids in the maintenance of healthy intestinal flora; acts as a coenzyme in the breakdown and utilization of protein; may restore gray hair to its original color if the graying was caused by stress or a nutritional deficiency; protects against second hand smoke, ozone, and other air pollutants; reduces inflammation caused by arthritis; improves flexibility; helps keep skin smooth; has been used to prevent and reverse accumulation of abnormal fibrous tissue, as occurs in various connective tissue diseases.
VITAMIN C (Ascorbic Acid)
A major and very potent anti-oxidant; plays a primary role in the formation of collagen, which is important for the growth and repair of body tissue cells, gums, blood vessels, bones and teeth; protects against the harmful effects of pollution; protects against infection, and enhances the immune system; helps protect against many forms of cancer by counteracting the formation of nitrosamines (cancer-causing substances); protects against abnormal blood clotting and bruising, and may reduce the risk of cataracts; aids in the treatment and prevention of the common cold; prevents scurvy; reduces the effects of many allergy producing substances; helps lower blood pressure; is vital for wound healing; strengthens the blood vessels; reduces cholesterol and protects against heart disease; aids in the production of "anti-stress" hormones; is needed for healthy adrenal function; helps expel heavy metals and other toxic substances from the body.
BIOFLAVONOIDS - HESPERIDIN - RUTIN
Is essential for the proper absorption and use of Vitamin C; promotes vascular health; protects and preserves the structure of capillaries, which will help prevent bruising, varicose veins and hemorrhoids; helps prevent blood clotting and platelet clumping by making the blood less sticky; lowers cholesterol levels; treats and prevents cataracts, glaucoma, and other vision problems; when taken with Vitamin C may reduce the symptoms of oral herpes.
QUERCETIN
A very potent bioflavonoid found in red wine, green tea, tomatoes, onions, and green beans. A natural anti-oxidant, which protects cells in the body from damage by "free radicals". Heart disease and high cholesterol is partially caused by free radical damage to blood vessels. May protect against heart attacks and strokes; recommended as a treatment for allergies, hay fever, and asthma because it helps prevent immune cells from releasing histamine, the chemical that initiates the itching, sneezing, and swelling of an allergic reaction; helps prevent itchy eyes, runny noses, and scratchy throats; in animal studies has shown to protect against a variety of cancers; may help stop cancer at its earliest stage by preventing the damaging changes in the cells that initiate cancer.
VITAMIN D
A deficiency plays a key role in the development of type 1 diabetes. Vitamin D is needed for islet cells to produce insulin, the hormone that allows cells to take up blood sugar. Without enough Vitamin D, islet cells don't produce insulin. Helps regulate white blood cells that make up the immune system; Vitamin D with calcium has shown to reduce osteoporosis and hip fractures; improves the absorption and utilization of calcium and phosphorus; hardens and repairs bones; prevents rickets, treats hypocalcaemia, and promotes normal growth in children; supports the healthy function of the thyroid gland; may help prevent colon cancer.
VITAMIN E
Is a "super" anti-oxidant, which protects cells against damage caused by "free radicals". Is extremely important in the prevention of cancer and cardiovascular disease, and is useful in treating premenstrual syndrome and fibrocystic disease of the breast. Thus far, studies have shown, that Vitamin E protects against approximately eighty diseases. It prevents thick scar formation when applied topically, and accelerates the healing of burns. It reduces blood pressure, aids in preventing cataracts, relieves leg cramps, and enhances sperm production; promotes healthy skin and hair and prevents age spots; retards cellular aging due to oxidation; prevents and dissolves blood clots; slows the progression of Alzheimer's disease; significantly strengthens the immune system; supplies oxygen to the blood which is then carried to the heart and other organs thus alleviating fatigue; treats circulatory problems and prevents lung toxicity from air pollution; enhances sexual performance; improves muscle strength and stamina. Studies have shown that low levels of Vitamin E in the blood increases the risk of certain types of cancer, particularly cancers of the gastrointestinal tract, breast, prostate, lung, and colon. Studies have shown that Vitamin E improves insulin action and it exerts a number of beneficial effects that aids in preventing long-term complications of diabetes, especially cardiovascular disease. Studies have shown that those who took Vitamin E on a regular basis had a 41 % lower risk of heart disease. Other studies have shown that people with existing heart disease, who started taking 400-800 IU of Vitamin E daily, had a 70% reduction in the number of heart attacks as compared to a placebo group.

4 eating healthy habits that boost your metabolism
What is metabolism? Scientifically, metabolism is the sum of all the chemical reactions that go on in the living cells that make up your body. Energy metabolism includes all the reactions by which the body obtains and spends the energy from food. In other words, the process your body uses to convert the calories from food into energy. And basal metabolism is the energy needed to maintain life when a body is at complete rest.
Believe it or not, the majority of energy one burns in a day is for basal metabolism. Basal metabolic rates vary among individuals. For instance, you may know someone who can eat anything and lots of it and yet never seems to gain a pound. On the other hand, you probably also know someone who has a very slow metabolism and eats less than other people and yet struggles greatly to maintain or lose weight. The difference may be in their basal metabolic rates. But, a person's metabolism is not the only factor that determines one's weight. How much you eat, when you eat, what you eat and how much you exercise all play important roles in determining your weight.
Here are some tips to help you "boost" your metabolism:
- Eat breakfast. Eating breakfast enables you to break your nighttime fast, which helps to jump-start your metabolism for the day. Also, breakfast eaters tend to be less hungry all day long and less impulsive about unhealthy snacking. Studies show that people who eat within 1-2 hours after waking are better able to control weight.
- Eat regularly. Skipping meals slows metabolism, causing you to burn less calories and store more calories as fat. Also, you tend to eat more later, especially less healthy choices. Eating every 4 - 5 hours is recommended.
- Eat protein with meals. Protein foods burn more calories to metabolize than carbohydrates and fats and also help you feel fuller for longer. Healthy protein sources include fish, chicken and turkey without the skin, lean meat, skim or 1% milk, eggs and egg substitutes, soy milk or tofu, low-fat, low-sugar yogurt, and beans (legumes).
- Eat adequate calories. Eating a very low calorie diet or skipping meals and taking in less than 1,000 calories a day causes your body to slow down in order to conserve energy.
Because metabolism slows down as you get older, it's even more important to follow the guidelines listed above to help you maintain a healthy weight as you age.

Metabolism boosting
Tip If your urine is darker than light straw in color, you may not be drinking enough fluid. Try sipping one glass before each meal and snack to stay hydrated.
True. But before you give yourself an ice cream headache, there's more. "The small difference in calories probably won't make a significant dent in your diet," explains Madelyn Fernstrom, PhD, CNS, founder and director of the UPMC Weight Management Center in Pittsburgh. On the bright side, different studies have suggested that five or six ice cold glasses of water could help you burn about 10 extra calories a day equaling about 1 pound of nearly effortless weight loss each year.
Tip Although the metabolism boosting effects are small, it can't
True. For every pound you lose, your resting metabolism drops by about 2 to 10 calories a day. Lose 10 pounds, and you now have to eat 20 to 100 fewer calories to maintain your trimmer physique, not factoring in exercise. However, you can prevent your metabolic rate from slipping while you get slim. One way is to lose fat but maintain muscle. You can do this by reducing calories and increasing aerobic and resistance exercise, says Hickey. Crash diets (fewer than 1,000 calories a day) may result in a higher percentage of muscle loss.
Tip Lose weight by cutting 250 calories a day and burning 250 calories per day through exercise. That will help you retain or even gain muscle while you lose a greater percentage of body fat.
True. Capsaicin, the bioactive compound that makes chile peppers exude heat, can turn your metabolism up a notch while also enhancing satiety and reducing hunger. Studies show that eating about 1 tablespoon of chopped red or green chile pepper which is equal to 30 mg of capsaicin resulted in up to a temporary 23% boost in metabolism. In another study, 0.9 g of red pepper was given in capsule form or naturally in tomato juice before each meal. The researchers noted that the individuals reduced their total calorie intake by 10 or 16%, respectively, for 2 days after and still reported being full.
Tip Sprinkle red pepper flakes onto pasta dishes and into chilis and stews; fresh chile peppers work well in salsas and add a fiery flavor to many other dishes.
True. Protein provides a metabolic advantage compared with fat or carbohydrates because your body uses more energy to process it. This is known as the thermic effect of food (TEF). Studies show that you may burn up to twice as many calories digesting protein as carbohydrates. In a typical diet, 14% of calories come from protein. Double that (and reduce carbs to make up for the extra calories), and you can burn an additional 150 to 200 calories a day, explains Donald Layman, PhD, a professor of nutrition at the University of Illinois.
Tip To reap protein's rewards, strive for between 10 and 20 g at each of your meals, says Hickey. Try an 8 ounce cup of low fat plain yogurt with breakfast (about 13 g), a 1/2 cup serving of hummus with lunch (about 10 g), and a 3 ounce salmon fillet for dinner (about 17 g).
False. Grapefruit won't work miracles for your metabolism, but it can help you lose weight. Half a grapefruit before meals helped individuals lose about 4 pounds in 12 weeks, according to a study published in the Journal of Medicinal Food. The reason: Its fiber and water fill you up on fewer calories, so you eat less at your next meal.
Tip Instead of soup or salad, try a juicy piece of fresh fruit half a grapefruit, a tangerine before your main course.
True. When you strength train enough to add 3 pounds of muscle, you increase your calorie burn by 6 to 8% meaning that you burn about 100 extra calories every day. Aerobic exercise, on the other hand, doesn't significantly increase your body's lean muscle mass. "The best way to gain muscle mass is to do resistance training," notes Ryan D. Andrews, RD, a certified strength training specialist in Colorado.
Tip "You want to focus on exercises that recruit the largest muscles and use two part movements, because they will help you build more lean mass," Andrews says. His favorites include squats, push ups, and any exercise that combines upper and lower body movements.
False. The thermic effect of food does cause your body to burn up calories as it processes meals, snacks, and beverages. But this process accounts for anywhere from 0 to 30% of the calories you eat (protein, for example, takes more calories to digest than fat or carbohydrates; see question 5). A medium size rib of celery has only about 6 calories; its TEF is approximately half a calorie. In reality, "negative calorie foods" are nothing more than wishful thinking.
Tip Include celery as a low cal but filling addition to salads, stir fries, and soups; you can't depend on it to magically melt away your trouble spots. But it is healthful: Celery has phthalides, compounds that can help reduce blood pressure.
True. Catechins found in green and oolong teas can boost the body's fat burning fire. One study of Japanese women compared the effects of drinking green tea, oolong tea, or water on various days. Just one large cup of oolong tea increased calorie burning by up to 10%, a boost that peaked 1 1/2 hours later. Green tea raised metabolism by 4% for 1 1/2 hours. Other studies show that drinking two to four cups of green or oolong daily (about 375 to 675 mg of catechins) may translate into an extra 50 calories burned each day about 5 pounds' worth in a year.
Tip Try a cup of green or oolong tea in place of your morning coffee for a dose of caffeine that will wake up your metabolism as well. Instead of milk or sweetener, add a squeeze of lemon, which may help your body absorb more catechins.
True. If there is a silver lining to PMS, it's that our resting metabolic rate may increase during the part of the menstrual cycle known as the luteal phase (the day after ovulation to the first day of your period). The metabolic boost we get from being "hormonal" can equal as much as 300 calories a day which is why our appetite increases during this phase.
Tip Keep a journal of what you eat the week before and the weeks after your period. Try to maintain your eating pattern over the course of the month so that you can take advantage of this hormone driven calorie burn. If you give in to cravings, make sure that you keep portions in check.
True. People who exercise at very high intensities experience a postexercise boost in resting metabolic rate that is larger and lasts longer compared with those who work out at a low or moderate level. Up the effort of your workout and you can expect to burn at least 10% of the total calories used during the workout in the hour or so after exercising. So, if you do a combo of walking and jogging for 4 miles (about 400 calories) instead of just walking, you may burn an extra 40 calories in the next few hours.
Tip Infuse your workout with bursts of speed. Gradually work your way up to 2 minute intervals, 3 days a week
