According to a study run by the University of Arizona and University of California Los Angeles, the year you were born could say a lot about the strains of influenza to which you are susceptible. The belief is that the first infection of flu you get when you are younger sets your immune system. And since there is usually a predominant strain of flu for a few decades at a time, it is most likely you7 were exposed to the one that was dominant around the time you were born. Key Takeaways:
"People's birth years can affect their risk of catching certain strains of influenza — probably because their first case of flu somehow sets their immune system . They've been spilling over into people for years and scaring scientists who see the potential for a pandemic of flu that could kill tens or even hundreds of millions of people." Reference:

In today’s stressful world, immune system health is more important than ever. History has proven that no matter what we do to combat viruses, bacteria and parasites, they have the remarkable capability to mutate for survival, often returning in a more virulent form than before. New strains of the flu and other microbial invaders are being discovered at an alarming rate, and modern medicine is constantly on the defensive. At the time this was written, the Centers for Disease Control (CDC) in Atlanta is predicting a “bad flu season” because a “killer drift variant” strain of flu had been discovered, called type A Fujian. This new strain has already caused deaths abroad, and vaccinations are strongly recommended, especially for the very young and the elderly. However, mutating microbes are only part of the problem confronting our immune systems. Factors such as environmental pollution and over-processing of foods are believed by many researchers to play a major role in many health conditions. Which means, more than ever before, you need to make sure your immune system is functioning at peak efficiency. Fortunately, there are a number of natural products available that can assist you in reaching this goal. One of the most effective discovered to date is Olive Leaf Extract (OLE). Natural olive leaf extract is derived from the olive tree (Olea europaea), which happens to have a very long and interesting history. One of the most revered botanicals, the olive tree is mentioned numerous times in the Bible. One of the earliest and most powerful mentions is the delivery of the olive branch to Noah by a Dove, a sign that the floodwaters were receding and life was returning. The olive tree was, and still is, a life-giver. It’s fruit is used for food, and the oil is used for cooking and as a source of light to ward off the darkness. Ancient cultures soon discovered that the various components of the olive tree provided a myriad of health benefits as well, benefits confirmed by modern science. Extract of olive leaves is one of the best, if not THE best, natural antimicrobials and antioxidants ever discovered.* Oddly enough it might have been well recognized in this role much sooner since it was reported in the mid-1850’s that a bitter tea brewed from olive leaves might be a potential cure for malaria. However, not all great discoveries are immediately recognized as valuable, and physicians of that era didn’t give much credence to the reports. It wasn’t until decades later that a simple analysis conducted on olive leaves led to the discovery of an active component, the phenolic compound oleuropein, which has since been associated with many health benefits. More recently, numerous studies have been conducted on olive leaves and the active components found in the leaves, with a preponderance of positive results. A 1999 study conducted at the University of Rome assessed the antimicrobial activity of oleuropein and hydroxytyrosol, two of the most active components in olive leaf extract. They were pitted against many different bacterial strains, including salmonella and staphylococcus, in vitro. The study concluded, “Olea europaea can be considered a potential source of promising antimicrobial agents” for the support of intestinal and respiratory health.* 4 A 2002 study conducted at the University of South Australia compared the effectiveness of some of the typical components of the Mediterranean diet, including oleuropein and hydroxytyrosol, as reactive oxygen species inhibitors and free radical scavengers. Researchers also examined their capability in protecting against low-density lipoprotein oxidation in vitro. Results clearly indicated that these components are potent inhibitors of free radical generation, as well as effective free radical scavengers.* 5 NOW® Foods carries a number of olive leaf extract products, including our Olive Leaf Extract 500mg, standardized to contain 6% oleuropein, our Extra Strength product with 18% oleuropein and 100mg of Echinacea Extract, and Olive Leaf Glycerite liquid, which contains 18% oleuropein. Why would you want a standardized Olive Leaf Extract product over a whole herb Olive Leaf product? We’re glad you asked! Standardization allows for consistently effective herbal products because the active ingredient, or marker compound, is accurately identified and measured, ensuring that the product delivers a certain minimum level of the active component or components. In simpler terms, standardized herbal products allow the consumer to obtain the benefits of an herb without having to consume massive quantities because there is a much greater concentration of active components, which also improves the effectiveness of the herbal product. Purchasing standardized Olive Leaf with a guaranteed concentration of oleuropein is a smart choice.

Date:
June 09, 2005 09:27 AM
In 1912, Casimir Funk coined the term 'vitamine' to refer to a 'vital factor' he proposed was an essential component present in foods. His conjecture Dovetailed with other research, leading to the isolation in the 1930's and 40's of the compounds we now call vitamins. Vitamins are chemical substances which play a variety of roles in the human body. They are core components of any nutritional supplementation program. While many people are aware of vitamins as necessary substances for good nutrition, few have a grasp of the extraordinary complexity of the roles they play in our bodies. As you'll see below, vitamins are involved in trillions of biochemical interactions every minute to keep us alive and functioning. For example, B-vitamins are converted into coenzymes which are directly necessary for the production of ATP energy from food, a process that goes on continuously in every cell in the body and which in turn fuels myriad physiological events such as muscle contraction, brain activity or tissue repair. Source Naturals offers a full line of vitamins in bioactive forms, allowing you to tailor a nutritional supplementation plan to your individual needs.
VITAMIN A and CAROTENOIDS Vitamin A Vitamin A is a generic term for a class of fat-soluble substances called retinoids, which can either be consumed preformed or synthesized by the liver from plant pigments called carotenoids (see 'Carotenoids', below). An essential nutrient, vitamin A is perhaps best known for its role in vision. The outer segments of the rods, a type of light-sensitive cell in the retina of the eye, contain a pigment called rhodopsin (or 'visual purple') that mediates vision in dim light. Cone cells mediate color vision via three additional pigments. Both rods and cones are surrounded by pigmented epithelial cells that store vitamin A. Rhodopsin is formed from a protein called opsin and a vitamin A-dependent compound called 11-cis retinal. As light strikes the rods and cones it is absorbed by the pigment molecules, and retinal is split off from opsin. This chemical change allows an electrical impulse to be sent to the optic nerve and thus to the brain. The pigment must then be regenerated from opsin and retinal. Repeated small losses of retinal during this process require a constant replenishment of vitamin A to the eyes. Vitamin A also plays an extremely important role in epithelial cell differentiation. Cell differentiation is the process by which a cell undergoes a change to a specialized cell type, allowing it to perform particular functions in the body. It is not yet understood precisely how vitamin A is involved in this process. One hypothesis is that it directly affects gene expression through its interaction with chromatin, a complex of DNA, RNA and protein in the cell nucleus. These interactions affect the process of transcription of DNA to messenger RNA, leading to synthesis of a specific group of cellular proteins. Each one of us carries in our DNA a unique genetic blueprint. This genetic material is the same in every cell of our bodies. It is only because of this mysterious and magical process of differentiation that we have specialized cell types - and therefore eyes, ears, lungs and hearts. Vitamin A is necessary, either directly or indirectly, for the healthy growth and functioning of many of our tissues and organ systems, including the eyes, the skin, the bones, the reproductive system, and the natural defenses. It is not yet known whether this requirement is due to the role of vitamin A in cell differentiation or whether there are other physiological processes for which vitamin A is essential. Carotenoids Vitamin A is related to a class of nutrients called carotenoids, including alpha and beta carotene, lycopene and lutein. Carotenoids are botanical pigments whose colors range from red to orange to yellow. Some carotenoids, particularly beta carotene, can be converted into vitamin A predominantly in the intestinal mucosa and to some extent in the liver. Carotenoids are completely non-toxic; their conversion into vitamin A is well-regulated by the body, making them extremely safe sources of this essential nutrient. In addition to their role as safe sources of vitamin A, carotenoids are powerful nutrients in their own right. Their primary claim to fame is their powerful antioxidant action, particularly against singlet oxygen. Singlet oxygen is an 'excited' ion of oxygen which, while not technically a free radical, is nonetheless highly reactive. It causes 'oxidative' reactions which can impair or destroy membranes, enzymes and DNA. It can also lead to the formation of free radicals which can cause additional damage. Certain carotenoids such as beta carotene, because of their chemical structure, can neutralize singlet oxygen by absorbing its extra energy and dissipating it throughout the carotenoid molecule, releasing the energy as heat and converting the singlet oxygen back to 'normal' oxygen. One molecule of beta carotene can quench up to 1000 molecules of singlet oxygen. In addition to their role as singlet oxygen quenchers, carotenes provide antioxidant protection against free radicals as well. In nature, they protect plants from photo-oxidative reactions; in humans, certain carotenoids, notably beta carotene, may help protect the skin from such reactions. Other carotenoids may provide more localized protection to particular organs. Lutein and zeaxanthin, for example, are selectively concentrated in the retina of the eye. Along with vitamins C and E, carotenes are among the most important nutrient antioxidants in the human body.
