Vitamins, Minerals & Antioxidants: What They Are & What They Do

• 13 Vitamins Your Body MUST Have •

  1. B1 (thiamin) - (part of the B-Complex Family) conversion process of blood sugars into glucose. It also helps the body break down carbohydrates, proteins and fats. Sufficient levels of Vitamin B1 also ensure that the nervous system and the cardiovascular system work optimally. Proper muscular functioning is also dependent on sufficient quantities of this vitamin. The production of adenosine triphosphate (ATP), which is the body's main source of fuel, could not happen without this B1. The heart in particular relies on this fuel supply so that it can keep up with its most important job of circulating blood throughout the body and supplying the blood cells with oxygen.
    Food Sources: pork, whole grain cereals, wheat germ, navy beans, kidney beans, garbanzo beans (chickpeas), peas, peanuts, fish, oysters, whole wheat and rye flour, oranges and orange juice and raisins. The best sources are found in beef liver and kidneys and in brewer's yeast.
    Warnings: None; as a water-soluble vitamin it is constantly needing to be replenished.

  2. B2 (riboflavin/Vitamin G) - (part of the B-Complex Family) assists with the metabolization process of proteins, fats and carbohydrates. It is needed to maintain the mucous membranes that are located throughout the digestive tract, and for proper formation of red blood cells. Riboflavin helps the body produce antibodies, and it is an important part of the processes involved with cell respiration and growth. This vitamin benefits skin, hair, finger and toenails and the connective tissues. As part of the B-complex family, Vitamin B2 is necessary for the production of niacin (Vitamin B3) and it helps the body absorb vitamin B6. During periods of rapid development (such as during puberty) this vitamin helps ensure that development occurs normally.
    Food Sources: Milk, eggs and dairy products such as yogurt and cheese are excellent sources of Vitamin B2 as are leafy green vegetables, avocado, broccoli and asparagus. Enriched and whole grains and cereals are other good sources and so are nuts, legumes, soybeans and mushrooms. Fruits, organ meats (liver, kidney and the heart) and fish contain ample amounts of this vitamin as well.
    Warnings: None; as a water-soluble vitamin it is constantly needing to be replenished.

  3. B3 (niacin) - (part of the B-Complex Family) facilitates the processes of metabolizing fats, proteins and carbohydrates. Niacin helps the arteries widen, which enables blood to circulate more easily. Also, because niacin lowers the body's bad cholesterol levels (LDL), it helps prevent plaque from forming and plaque build-up on artery walls resulting in improved blood flow and a reduced risk of heart attack. Vitamin B3 keeps the body's nervous system, digestive tract and overall mental well-being functioning properly. Healthy skin requires a regular supply of this vitamin, and it is also required in order to produce various hormones including progesterone and testosterone.
    Food Sources: organ meats (kidney, liver), lean meats, pork, prawns, and cow milk. Other sources include seeds and almonds, rice bran, wheat products, beans, green vegetables, turnips, carrots, and celery.
    Warnings: Though water-soluble, some individuals who digest niacin can experience a red flushness on the skin, a tightening at the wrists, neck and in the legs, and excrete yellow sweat. If this happens, slow intake and allow the body to get used to niacin.

  4. B5 (pantothenic acid) - (part of the B-Complex Family) this one vitamin is used by literally all of the functions the body performs. Like the other members of the B-complex family, Vitamin B5 has a major role in the metabolism process that converts carbohydrates, fats and proteins into energy. In addition, it acts as an adrenal gland stimulant. As the glands are stimulated, the production of adrenal hormones, and especially cortisone, increases. The vitamin is also believed to be capable of reducing fatigue and thereby enhancing stamina levels. Pantothenic Acid is crucial for the production of antibodies, too. Many specialists agree that it can help the body fight off the symptoms of stress, anxiety and even depression. It also helps to lower bad cholesterol levels and that helps reduce the risks involved with heart disease. It can help prevent arthritis or if it is already present B5 can help to alleviate the symptoms of this painful condition. Hormone production depends on a steady supply of Vitamin B5 and so does the creation of healthy red blood cells and hemoglobin. Healthy skin and hair both are possible because of this important B vitamin, in fact, B5 has been used to treat acne and rosacea. It helps wounds heal faster. And finally, this powerhouse can help slow the aging process.
    Food Sources: eggs, yeast, poultry, meat, fish, liver, milk, sunflower seeds, soy beans and bean flour, peas, peanuts, peanut butter, legumes, broccoli, collard greens, bananas, oranges, mushrooms, whole grain products and wheat germ.
    Warnings: One thing that should be noted about Pantothenic Acid is that it breaks down easily in heat. Care must be taken during food preparation. As a water-soluble vitamin it is constantly needing to be replenished.

  5. B6 (pyridoxine/pyridoxal phosphate) - (part of the B-Complex Family) the most quickly metabolized member of the B-vitamin family. Like the rest of the B-vitamins, pyridoxine plays a role in the metabolism process that converts proteins, fats and carbohydrates into a form of energy the body can use. It helps produce healthy hemoglobin by making more iron available. Even more impressive, this vitamin plays a role in the production of over 60 different hormones, enzymes, prostaglandins and neurotransmitters. Vitamin B6 is directly involved in the production of the mood, sleep and appetite regulator called serotonin. B6 can help prevent the formation of painful kidney stones and adequate quantities will help promote a healthy immune system. It helps lower the levels of bad cholesterol in the blood making fatty plaque deposits are less likely to form on artery walls and greatly reducing the risks of heart attack. It's believed that the way B6 joins together with folic acid and B12 also helps reduce the risk of heart attack. Together this combination may lower homocysteine levels.
    Food Sources: poultry, pork, fish, milk, eggs, nuts, seeds, brown rice, whole grains, bananas, carrots, avocados, soybeans and whole grains
    Warnings: Though it needs to be replenished regularly, B6 is one of the few vitamins that when taken in excess, can actually be toxic. Taking more than 2 grams a day can result in irreversible damage to the nerve endings and to the entire neurological system. Although up to 500 mg/day is considered high, this level still is considered safe. Women need 1.2-1.6 mg/day where men need 1.3-1.7mg/day.

  6. B9 (folic acid) - (part of the B-Complex Family) Like the other B-vitamins, Vitamin B9 plays a role in the body's ability to metabolize fats, proteins and carbohydrates so they can be converted into energy. But folic acid benefits the body in many other ways, too. B9 is required to help form DNA and other nucleic acids. Since DNA and other nucleic acids are created along with new cell growth, this vitamin plays a crucial role in the body's ability to create red blood cells and the heart disease fighting amino acids called homocysteine. Folic acid also assists in the production of heme, the pigmented part of the red blood cells that carry iron. Folic acid also plays a significant role in the body's ability to repair damaged tissues. It plays a role in the development of serotonin, the neurotransmitter responsible for regulating sleep, moods and appetite. It helps with the digestion process. And it may help protect against the onset of cervical cancer. Ample quantities of folic acid are also extremely important for any woman planning to conceive. Its presence can help protect the developing fetus from such dangerous conditions as spinal bifida. Four to six weeks after conception, the neural tube begins to form in the growing fetus. This tube ultimately becomes the spine, spinal cord, skull and brain. Closing the neural tube so amniotic fluid cannot seep in is the final step of the tube's development. Folic acid ensures this closure. Failure to close can result in birth defects including spinal bifida or anencephaly.
    Food Sources: green leafy vegetables such as spinach and asparagus, organ meats including liver and kidney, nuts, beans and legumes, shellfish, poultry, pork, whole grains, citrus fruits, fruit juices and yeast
    Warnings: Though excessive consumption of B9 does not present a dangerous situation, care should be taken to keep consumption in moderation. Men and women should get 300 to 400 micrograms daily. Pregnant women, especially during the early stages of pregnancy and women attempting to conceive, should increase their intake of B9 to 600 micrograms/day. This vitamin is easily broken down during the cooking process so care must be taken during food preparation.

  7. B12 (cobalamin) - (part of the B-Complex Family) known as the energy vitamin, adequate levels of B12 have been shown to increase alertness, reduce tiredness and leave people feeling overall invigorated. One of the most important functions of Vitamin B12 is its ability to work together with B9 in the production of DNA. Because of the way it is able to recycle certain enzymes, it plays a significant role in maintaining the proper functioning of cells, blood and nerves. An imbalance of either Vitamin B9 or B12 can negatively impact the way red blood cells divide and lead to a condition known as pernicious anemia. It also works to reduce levels of homocysteine, the amino acids that can damage artery walls and increase a person's risk of developing heart disease. The vitamin is responsible for ensuring that nerve cells function properly. It's also possible that B12 can treat symptoms associated with a loss of calcium including osteoporosis and damage to the teeth. It may even be able to relieve some symptoms of depression.
    Food Sources: animal liver is the best source of Vitamin B12 (cyanocobalamin). Other good sources include fish, eggs, cheese and meat. It is important to note that Vitamin B12 is not found in plant tissue; those who consume a vegetarian-style diet are highly advised to subplement this all-important vitamin. Cereals, plant milk, soy products and brewer's yeast that have been fortified with B12 are also good sources.
    Warnings: None; as a water-soluble vitamin it is constantly needing to be replenished.

  8. Vitamin A (retinol) - a group of compounds that play an important role in vision, bone growth, reproduction, cell division, and cell differentiation (stem cells). It helps to regulate the immune system by making white blood cells and helping lymphocytes (a type of white blood cell) fight infections more effectively. Vitamin A also helps to prevent infections by promoting healthy surface linings of the eyes and the respiratory, urinary, and intestinal tracts, and by helping the skin and mucous membranes function as a barrier to bacteria and viruses. When those linings break down, it becomes easier for bacteria to enter the body and cause infection.
    Food Sources: whole eggs, milk, and liver (also check for fortified products such as skim milk), carrots, spinach, cantaloupe and apricots (most colorful fruits and veggies)
    Warnings: excessive Vitamin A use during pregnancy may increase the risk of birth defects. Vitamin A overdose can cause symptoms such as orange skin, blurred vision and nausea. Vitamin A toxicity can cause more severe symptoms such as growth retardation, hair loss and enlarged spleen and liver and even death. Ideally, adults should strive to get 700 to 900 micrograms of this vitamin each day. (900 micro grams for males, 700 micro grams for females, 750 micro grams during pregnancy and 1200-1300 micro grams during breast feeding).

  9. Vitamin C (ascorbic acid) - essential for the formation, growth, and repair of bone, skin, and connective tissue (including tendons, ligaments, and blood vessels). It helps maintain healthy teeth and gums, and helps the body absorb iron, which is needed to make red blood cells. It is necessary for the metabolizing of folic acid, iron, tyrosine and phenylalanine, otherwise the body could not use carbohydrates. It is also needed to synthesize fats and proteins. Probably the most important function of this vitamin is its antioxidant effects. Vitamin C is crucial to the body's ability to produce collagen, an important protein that keeps skin damage minimal. Collagen can delay the development of wrinkles and saggy skin by helping skin hold onto its elasticity. It can also help a person recover from the effects of a cold more quickly, while alleviating the symptoms. It also strengthens artery walls and makes them better able to resist the development of plaque build-up, and helps with the bone marrow's ability to produce red blood cells and hemoglobin and helps keep the nervous system healthy. Studies investigating this vitamins ability to slow down and possibly even prevent the formation of cataracts are ongoing and show promising results.
    Food Sources: citrus fruits - especially oranges, tangerines, limes, guava, lemons, papayas, strawberries, black currants, grapefruit and mangoes; vegetables including collard greens, sweet and hot peppers, broccoli, tomatoes, brussel sprouts, cabbage, potatoes, kale, spinach, and watercress.
    Warnings: None; as a water-soluble vitamin it is constantly needing to be replenished. To preserve more of the C content, eat these fruits and vegetables raw or only slightly cooked. Steam and exposure to light break down this vitamin.

  10. Vitamin D (calciferol) - is a steroid vitamin, a group of fat-soluble prohormones, which encourages the absorption and metabolism of calcium and phosphorous. It is the only vitamin that the body is capable of producing on its own with normal exposure to sunlight. An hour a week is generally enough. All of the body's other daily requirement of vitamins must come from the diet and/or via supplementation. Five forms of vitamin D have been discovered, vitamin D1, D2, D3, D4, D5. The two forms that seem to matter to humans the most are vitamins D2 (ergocalciferol) and D3 (cholecalciferol).
    Food Sources: the best sources are in steak-like fish such as salmon, mackerel and tuna, but you can also find good sources in sardines, liver and egg yolks. Fortified foods such as milk, orange juice, cereals, and some cheeses also contain Vitamin D, but be sure to check the labels.
    Warnings: Formerly it was considered unsafe in excess, but research is proving more Vitamin D can be better - excess Vitamin D created by your body is degraded as soon as it is generated.

  11. Vitamin E (tocopherol) - a combination of chemical compounds that include alpha-tocopherol. All tissues in the body contain this vitamin, but the largest quantities are located in the pituitary glands and the suprarenal glands. Vitamin E is another of the important vitamins that benefit the body in many different ways. First and foremost, it has antioxidant properties which neutralize free radicals and protect the body against the damaging effects they can cause. Along with Vitamins C and Vitamin A, these antioxidants help slow the aging process and can help prevent prostate and other types of cancer. Another important benefit is that it helps keep LDL levels low. This vitamin encourages the proper development of muscles. It can help boost the effectiveness of the immune system, primarily by making it more resistant to bacterial and viral infections. Working together with Vitamin C and beta carotenes, it can help prevent the development of cataracts.
    Food Sources: sweet potatoes and mangoes; oils including sesame, sunflower, peanut, safflower, olive, soybean and corn oil; nuts - walnuts, Brazil nuts, hazelnuts, sunflower seeds and almonds; butter, margarine, eggs, wheat germ, wheat germ oil, soya, yams, spinach, broccoli, corn, avocados, fortified cereals and liver are other good sources. Green vegetables contain small amounts of this vitamin.
    Warnings: Note that food storage and preparation can significantly deplete the E content of these foods. Freezing, processing, preserving and exposing these foods to air are the biggest Vitamin E degraders.

  12. Vitamin H (biotin) -

Free Radicals... What are They?

The human body metabolizes oxygen in order to produce energy, and "Free Radicals" are a natural by-product of this metabolic process. Free radicals are atoms or groups of atoms with unpaired or unbalanced electrons. In other words "Free Radicals" are unstable oxygen molecules that usually enter our bodies through breathing, eating, drinking etc. These volatile particles steal electrons from cells and other molecules within the body that can damage DNA. This in turn causes premature ageing and other diseases such as cancer, arthritis, Alzheimer's, cardiovascular disease including arteriosclerosis (hardening of the arteries). Free radicals react with Low Density Lipoprotein (LDL) cholesterol causing it to stick to the walls of arteries. LDL or bad cholesterol is a major contributor to coronary heart disease. They can cause failing eyesight due to the deterioration in the lenses of the eyes. Diseases such as Parkinson’s and dementia can result from the breakdown in cells of the nervous system. It is quite normal to have free radicals in the body. The body does create antioxidants to combat these unstable molecules. However, too many free radicals have the potential to do significant harm and upset the balance. That is why it is beneficial to add antioxidants through our diet.

Antioxidants... How They Help

Antioxidants are compounds that mop up free radicals and neutralize their impact on cells. Some of the most commonly known antioxidant supplements are Vitamin C, Ester C, Vitamin E, Alpha Lipoic Acid, Garlic, Coenzyme Q-10, Ginkgo Biloba, Bilberry, Lutein, Lycopene, Green Tea Extract, Grape Seed Extract, Omega 3 Fish Oils and Krill Oil, the mineral Selenium and Beta carotene which is a precursor of Vitamin A. Antioxidants are also present naturally in the food we eat in varying degrees. Some of the most powerful fruits are blueberries, cranberries, blackberries, raspberries, strawberries, cherries, prunes, red and black plums and apples. Some of the good choices in vegetable antioxidants are artichokes, russet potatoes, onions, garlic, kale, spinach, broccoli, beets, tomatoes, red bell peppers and brussell sprouts. Other powerful antioxidants are red beans, red kidney beans, pinto beans, and black beans.

Cloves, cinnamon, oregano, turmeric, ginger and rosemary are a few of the beneficial spices that we can add to our food that are high in antioxidants. Nuts and seeds are a huge source of antioxidants. Some of the heavy hitters are walnuts, pecans, hazel nuts, almonds, macadamia nuts, pine nuts, brazil nuts, pistachios, cashews, sesame seeds, sunflower seeds, ground flax seed and flax oil. Certain oils that we cook with or add to our salads can also have beneficial antioxidants in them. These antioxidants are oils such as olive oil (choose light for cooking and extra virgin for salads), walnut oil and sesame seed oil (both great for salads), canola oil, grape seed oil (also great for salads and cooking).

Fats & Cholesterol: The Good, the Bad & the Ugly

• HDL (the good) •

What is HDL?

High-Density Lipoprotein (HDL) is one of the five major groups of lipoproteins which enable lipids like cholesterol and triglycerides to be transported through the bloodstream. HDL is the smallest of the lipoprotein particles, but also the densest because they contain the highest proportion of protein.

• Metabolism Tricks •

Three factors determine your metabolic rate, which is the amount of calories your body uses every day. The basal metabolic rate (BMR) is the rate your body uses energy for vital body processes. The rate you burn energy during physical activity and the rate you use energy during digestion of food are the two other factors involved in your total metabolic rate. To improve your metabolic efficiency you only need to alter what you eat and what you do, just a little bit, to experience a difference in how you look and feel.
