Pressing tree-ripened olives extracts a flavorful, monounsaturated oil that is prized throughout the world both for cooking (particularly in Mediterranean countries) and for salads. Today's marketplace provides a wide selection of domestic olive oil (most of which comes from California) and imported oils from France, Greece, Italy and Spain. The flavor, color and fragrance of olive oils can vary dramatically depending on distinctions such as growing region and the crop's condition. All olive oils are graded in accordance with the degree of acidity they contain. The best are cold-pressed, a chemical-free process that involves only pressure, which produces a natural level of low acidity. Extra virgin olive oil, the cold-pressed result of the first pressing of the olives, is only 1 percent acid. It's considered the finest and fruitiest of the olive oils and is therefore also the most expensive. Extra virgin olive oil can range from a crystalline champagne color to greenish-golden to bright green. In general, the deeper the color, the more intense the olive flavor. After extra virgin, olive oils are classified in order of ascending acidity. Virgin olive oil is also a first-press oil, with a slightly higher level of acidity of between 1 and 3 percent. Fino olive oil is a blend of extra virgin and virgin oils (fino is Italian for "fine"). Products labeled simply olive oil (once called pure olive oil) contain a combination of refined olive oil and virgin or extra virgin oil. The new light olive oil contains the same amount of beneficial monounsaturated fat as regular olive oil...and it also has exactly the same number of calories. What the term "light" refers to is that--because of an extremely fine filtration process--this olive oil is lighter in both color and fragrance, and has little of the classic olive-oil flavor. It's this rather nondescript flavor that makes "light" olive oil perfect for baking and cooking where regular olive oil's obvious essence might be undesirable. The filtration process for this light-style oil also gives it a higher smoke point than regular olive oil. Light olive oils can therefore be used for high-heat frying, whereas regular olive oil is better suited for low- to medium-heat cooking, as well as for many uncooked foods such as salad dressings and marinades. The International Olive Oil Institute recommends using pure olive oil for frying, since the flavor of extra virgin olive oil tends to break down at frying temperatures, making the added expense a waste. Olive oil should be stored in a cool, dark place for up to 6 months. It can be refrigerated, in which case it will last up to a year. Chilled olive oil becomes cloudy and too thick to pour. However, it will clear and become liquid again when brought to room temperature

Soy lecithin is a mixture of fatty substances that are derived from the processing of soybeans. Lecithin is separated from soybean oil by the addition of water and centrifugation (rapid spinning) and purified for use as a food additive. Its chemical name is phosphatidylcholine, which identifies its major components of choline, phosphoric acid, glycerin, and fatty acids. Lecithin is used widely in foods as an emulsifier, stabilizer, and antioxidant.



Studies show most soy-allergic individual can safely eat products containing soy lecithin without experiencing any allergic reactions.



Although soyfoods are widely recognized for their nutritional qualities, interest in soyfoods has risen recently because scientists have discovered that a soy component called isoflavones appears to reduce the risk of cancer. More research needs to be done to determine exactly how isoflavones work, but it appears that as little as one serving of soyfoods a day may be enough to obtain the benefits of this anticancer phytochemical.



Traditional soy products such as tofu, tempeh, and soy milk are very high in protein. Tempeh has the highest percentage of protein of the traditional soy products providing approximately 22 grams of protein for each 4 ounce (113 gram) serving. Tofu provides approximately 9 grams of protein for a similar small serving size. The Recommended Dietary Allowance of protein for adult males (aged 25-50) is appoximately 63 grams and 50 grams for adult females (aged 25-50). Soy products can provide a significant portion of one's daily protein needs.



It is important to keep in mind, however, that the balance of amino acids (protein building blocks) in soy is not the same as meat. Because soy foods does not have an ideal balance of amino acids, some experts recommend taking in a little extra soy foods and/or combining soy products or legumes with a whole grain dish at meals where other protein (e.g., eggs, fish) is not eaten. The amino acids in whole grains combine well with amino acids in soy and legumes to make a more ideal balance of amino acids. If a person's diet is reasonably-balanced, however, there is usually no need to be concerned about getting enough protein.

Vegetarians and health enthusiasts have known for years that foods rich in soy protein offer a good alternative to meat, poultry, and other animal-based products. As consumers have pursued healthier lifestyles in recent years, consumption of soy foods has risen steadily, bolstered by scientific studies showing health benefits from these products. Last October, the Food and Drug Administration gave food manufacturers permission to put labels on products high in soy protein indicating that these foods may help lower heart disease risk.



As with health claims for oat bran and other foods before it, this health claim provides consumers with solid scientific information about the benefits of soy protein and helps them make informed choices to create a "heart healthy" diet. Health claims encourage food manufacturers to make more healthful products. With soy, food manufacturers have responded with a cornucopia of soy-based wares. (See "The Soy Health Claim.")



No sooner had FDA proposed the health claim regulation, however, than concerns arose about certain components in soy products, particularly isoflavones. Resulting questions have engulfed the regulation in controversy.



This came as no surprise to Elizabeth A. Yetley, Ph.D., lead scientist for nutrition at FDA's Center for Food Safety and Applied Nutrition . "Every dietary health claim that has ever been published has had controversy," she says, "even the relationship of saturated fat to a healthy diet."



While the controversy may seem confusing to the consumer giving it casual consideration, a careful review of the science behind the rule reveals a strict divide between what FDA allows as a health claim based on solid scientific research and related issues that go well beyond the approved statements about health benefits of soy protein.

Water is the most abundant nutrient in our body and plays an important transmission function in every body cell and tissue. Sixty percent of our body weight is water. The fact that you can live without food for a long period of time, even months, but live only for a few days without water is true. Under normal conditions, the body releases about one quart of water daily. Therefore, replacement to equal the losses is very important for survival.

Dehydration is the most common problem of water imbalance due to water losses and deprivation. The effects of dehydration on nutrition can adversely affect ones health. Dehydration is the major cause of ones diminished ability to perform during endurance activities. Body water is lost through the stomach, respiration, sweat, and the kidneys. It is recomended that 24oz of water a day should be taken. This amount can double or even triple with endurance type exercise.



A note about water: More and more evidence shows the benifit of being well hydrated.

Studies show that 75% of Americans are chronically dehydrated (likely applies to half the world's population), leading to possible health problems such as fatigue. In 37% of Americans, the thirst mechanism is so weak that it is often mistaken for hunger, leading to over-eating. Even MILD dehydration will slow down one's metabolism as much as 3%.



Bottled Water: Some types of bottled water are not subject to the same regulations as tap water. These are regulated as food products, and their regulations are largely related to sanitary food handling and processing practices. Bottled water manufacturers will provide a detailed report on the quality of their product to consumers who call to request it.

A propellant is a material that is used to move ("propel") an object. This will often involve a chemical reaction. It may be a gas, liquid, plasma, or, before the chemical reaction, a solid.



Common chemical propellants consist of a fuel, like gasoline, jet fuel and rocket fuel, and an oxidizer
