Tuna are several species of ocean-dwelling fish in the family Scombridae. Tuna are fast swimmers and like most other fish species are cold-blooded. Unlike most ocean fish species, which have white flesh, the flesh of tuna is pink. This is because the tuna's blood has a higher oxygen carrying ability than other fish species. Some of the larger tuna species such as the bluefin tuna can raise their blood temperature above the water temperature with muscular activity. Though not really warm-blooded, this enables them to live in cooler waters and survive a wider range of circumstances.



Tuna, an excellent source of lean protein, vitamins and minerals but also is low in saturated fats and cholesterol. Tuna can also help lower blood pressure and cholesterol. Research has shown that omega-3 fatty acids, found in abundance in fatty fish like tuna can help lower the risk of heart disease, ease the pain of arthritis, reduce asthma complications, and is essential in the growth and development of young children.

Mercury levels are oftentimes relatively high in tuna, as they sit higher in the food chain. Tests conducted by the U.S. Food and Drug Administration show that Albacore "white" canned tuna has three times the mercury levels of that found in "light" tuna.

Despite these findings, the FDA still refuses to warn women and children to limit canned tuna consumption like twelve states have already done. FDA"s new advice that it is safe for women and children to eat up to 12 ounces of seafood, including white tuna containing mercury levels over 0.3 parts per million, is placing millions at risk of mercury exposure according to Michael Bender of the Mercury Policy Project. This level of consumption would exceed the EPA's reference dose which is a health standard endorsed by the National Academy of Science.



Canned tuna is one of the richest and most convenient sources of Omega-3. With benefits ranging from protective and preventive qualities on overall cardiac health and improved eye and skin health, the omega-3 acids found in tuna are an essential component of a balanced diet. Fortunately, omega-3's are abundant in most types of seafood but especially in cold-water varieties like tuna, one of the most omega-3 rich fish species.

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.

Salt is one of the most ubiquitous food ingredients around. Those who think of salt only as something used to perk up flavor might wonder what could possibly give this ingredient the level of importance it has gained through the ages. In reality, there is much more to this crystalline cube than first meets the eye.



Besides enhancing taste, salt has several other functions in food products. It acts as an antimicrobial or microbiological control agent. It contributes to certain chemical reactions that create a wide variety of food characteristics.



Sometimes the terms "salt" and "sodium" are used interchangeably, but technically this is not correct. "Salt" is sodium chloride. By weight, it is 40 percent sodium and 60 percent chloride.

Most foods and tap water contain sodium and chloride. Sodium is an essential nutrient, a mineral that the body cannot manufacture itself.

Because of sodium's importance to your body, the excretory and nervous systems guard against under-consumption of salt, which is a threat to your body's nerves and muscles. Other ions such as calcium, magnesium, and potassium are also very important. Concentrations of these ions are held in narrow ranges by the kidney.



The association between eating salt and the risk of blood pressure increasing is difficult to quantify. Some people are sensitive to changes in salt intake whereas others can adjust so that blood pressure does not rise at all.



Americans typically consume 4,000-8,000 mg each day, well above their daily needs. A goal for moderation for all adults, (including pregnancy and lactation) is approximately 2,400 mg of sodium per day.

A chemical compound that is used to preserve food by retaining the moisture in the food to make it juicy and more pleasing when consumed.

According to Larry Borchert, a professor of

muscle biology and meat science at the

University of Wisconsin at Madison, hams do

not naturally hold water. The two proteins that make up the muscles of a ham, actin and

myosin, bind together to form a complex

protein known as actomyosin. Actomyosin is

not water-soluble, but it is salt- soluble. Thus ham manufacturers

must inject sodium phosphate into

supermarket hams to

enable the muscles to retain water. The

advantage of this treatment can be that a ham does not end up completely

dehydrated after processing. The disadvantage, however, is that the ham can be so pumped up with water, or "highly extended," as Borchert phrased it, that it

takes on an unpalatably damp, spongy texture

and a watered-down flavor. This was the case with all of the "water product" hams and, to a lesser degree, the "hamwater
