Risks and Benefits of Cod Liver Oil

There are health benefits of cod liver oil and there are drawbacks. Cod liver oil benefits may not outweigh the risks. The primary benefit of cod liver oil is related to its omega-3 content, but fish oils derived from the flesh of fish, rather than the liver, provide that benefit without the risks.

Nutritional Vitamin Supplements

The health benefits of cod liver oil are related, primarily to omega-3 fatty acids. These are essential for the healthy function of the brain, the heart, the joints, the digestive system and many other systems of the body. Another benefit of cod liver oil is related to its vitamin E content, which helps the body process the fatty acids, is an essential antioxidant and promotes the health of the skin and the hair.

Omega-3 Fatty Acids/Benefits of Cod Liver Oil

Omega-3s are essential to human health, cannot be produced inside the body, and so, must be obtained from food or through supplementation. The best know source of omega-3 fatty acids is fish. Some fish contain more omega 3s than others.

There are two types of omega-3 fatty acids that have been identified as essential for human health. They are Docosahexaenoic Acid or DHA and Eicosapentaenoic Acid or EPA. These are found primarily in fish. The body can convert another omega-3 fatty acid, known as Alpha-linolenic acid or ALA, to DHA and EPA, but the process is relatively inefficient. It is believed that one would have to consume a great deal of ALA in order to get the health benefits provided by DHA and EPA.

The omega-3 found in flax seed oil is ALA. And some believe that flax seed oil can provide cod liver oil benefits, without the risks, but this is debatable. Although there are no risks associated with flax seed oil, it is unknown if ALA provides the same health benefits as DHA and EPA.

The Risks

Cod liver oil contains large amounts of vitamin A and vitamin D and may contain contaminants such as mercury and pesticides. The body needs adequate amounts of vitamin A, but large amounts can be toxic. Vitamin D is not commonly found in natural foods, but many processed foods are fortified with vitamin D to ensure good nutrition.

At one time the benefits of cod liver oil were believed to be associated with its vitamin A and D content. This was before omega-3 fatty acids had been identified and before food fortification was a common practice. It was also before taking daily multi-vitamins became a common practice and before industrial pollutants had contaminated our oceans.

Vitamin D

While no tolerable upper limit for vitamin D consumption has been established, adequate intake for adults, under the age of 50, and children is believed to be around 200 units per day. Adults over 50 should increase consumption to 400 units per day for men and 600 units per day for women. Vitamin D is necessary for the body to process calcium and is therefore a factor in preventing osteoporosis and maintaining bone health. However, one of the popular cod liver oil products contains 4000 to 5000 units of vitamin D per teaspoon, more than anyone needs on a daily basis.

Vitamin A

A tolerable upper limit for vitamin A has been established. The maximum amount of vitamin A that a 25 year old man should consumer per day is 10,000 IU. Women should consume less than half that amount. Women who are pregnant should avoid dietary supplements that contain vitamin A because of the risk of birth defects. While vitamin A is necessary for fetal development and overall good health, it is stored in the fat cells and there is a great risk of over supplementation. Excess consumption of vitamin A is also believed to contribute to osteoporosis.

One of the popular cod liver oil products contains 4000-5000 IU of vitamin A, per teaspoon. When added to the amount that may be present in other dietary supplements, as well as the food that a person consumes per day, it will put most people over the safe upper limit for vitamin A. While the benefit of cod liver oil for supplying essential omega 3s is known, it is unknown if excess consumption of vitamin A will counteract those effects.

A better choice for vitamin A supplementation is beta carotene and other carotenoids. Present in the better daily dietary supplements, carotenoids are converted by the body to vitamin A on an as-needed basis and are not associated with the negative effects of "pre-formed" vitamin A. The only known side effect of excess consumption of carotenoids is a yellowing of the skin, called carotenosis, which is not dangerous, but may be undesirable.

Alternatives

Fish oil derived from the flesh of fish does not contain the vitamins A and D. Those vitamins are usually present in adequate amounts in daily multi-vitamins and fortified foods. Though extra vitamin D supplementation is often recommended for persons over the age of 50, it is not a benefit of cod liver oil and there are better choices for vitamin D supplementation.

From an environmental standpoint, over harvesting of the cod fish has led to the depletion of many populations. Farms affect the health of wild fish. The equipment used for harvesting damages the habitat of other water dwelling life forms. Although there are cod liver oil benefits, these health benefits can be obtained from other sources that do not cause damage to our environment.

You can get the health benefits of cod liver oil by taking fish oil supplements derived from the flesh, rather than the liver of fish. To learn more, please visit the Fish Oil Guide.

Vitamins And Supplements For Women

Vitamins and Minerals - The Role

These important nutrients are essential to good health since they help the body use the energy stored in food. If you eat a balanced, varied diet, vitamin and mineral supplements are probably unnecessary.

Nutritional Vitamin Supplements

A surprising number of people take vitamin or mineral supplements each day as a kind of nutritional insurance - usually without understanding how they work and what they do. Nutrients such as riboflavin, vitamin C, zinc, and many others are essential to good health, but they are no substitute for food. In fact, vitamins and minerals are facilitators that enable the body to make use of the energy stored in food. These nutrients in and of themselves are of little value of the body. Simply taking vitamin and mineral supplements without eating food is like sending in bricklayers to build a wall, but neglecting to supply the bricks.

Nutritional Vitamin Supplements

What vitamins do which is crucial to the normal maintenance of healthy cells, is perform an extraordinary range of functions in the human body. They not only help convert food into useable energy, but they also assist in the manufacture of blood cells, hormones, and the chemicals of the nervous system.

Vitamins are divided into two categories, which are water-soluble and fat-soluble. The four fat-soluble vitamins, A, D, E and K, are absorbed into body fat and may be stored for later use. If taken in excess, however, some fat-soluble vitamins can accumulate in toxic amounts. Vitamin C and the eight B vitamins are all water-soluble meaning that they dissolve in body fluid, and most of the excess is eliminated through sweat or urine. As a result, there is little concern about toxic overdoses although excessive doses of B6 can be toxic.

Minerals play a part in the maintenance of immune cells, in blood coagulation, in the synthesis of oxygen in the blood, in bone formation, and in numerous other functions. Some, such as calcium, phosphorus, and magnesium, are necessary in fairly large amounts. The need for others, known as trace minerals, is much smaller. In fact, although they are present in human tissue, a few of these trace elements play such dubious roles that they are considered nonessential. The essential trace minerals include iron, zinc, fluoride, and copper. Any of these minerals, whether essential or nonessential, is toxic if ingested in sufficient amounts for long enough periods.

How necessary are supplements? For years, controversy has raged between those who believe supplements are necessary and those who say that they are at best a waste of money and, at worst, a hazard to health. With few exceptions (notably vitamins D and K), the human body cannot make its own vitamins or minerals, so they must be obtained from foods. The traditional view holds that a balanced diet will supply all the vitamins and minerals that are necessary to maintain a good health.

The opposing argument for supplements is that many modern diets lack balance. In fact, they are so loaded with processed and refined foods that they cannot provide adequate amounts of essential vitamins and minerals. Furthermore, because many people skip regular meals and instead rely on fast foods, and nutritionally vacuous snacks, supplements may be a necessity. Other proponents of supplements claim that the chronic stress bought on by fast-paced lives can increase our need for these important nutrients.

Vitamin E - Did You Know Palm Oil Is Packed With This Nutritional Supplement?

Vitamin E: The briefest of introduction!

Nutritional Vitamin Supplements

A combination of 8 related molecules known as tocopherols constitute the Vitamin E. The most biologically active amongst them are Alpha-Tocoperols and they are responsible for most of the benefits the body receives from the absorption of this particular nutritional supplement It is a stable fat-soluble vitamin, which means that our body can easily break down its potency and nutrients. The daily allowance for Vitamin E, as recommended by the US FDA is measured at 8 to 10 milligrams (15 IU) per day. There are a number of experts however who recommend a much large daily dosage such as Dr. William Shute. (In his widely acclaimed Book of Vitamins, he suggests a daily dose of at least 800 (up to 1600) IU.) This high dosage is thought to play a beneficial part in the prevention of arterial degeneration, which is a devastating vascular damage caused by diabetes.

Nutritional Vitamin Supplements

Vitamin E: How is it beneficial. (If you must know something, then let it be the following!)

According to a research conducted by the folks at Yale University, the unwelcome physical decline that goes hand in hand with aging can be positively affected by a daily intake of this substance. This doesn't mean old folks who were finding difficult to get out of bed will all of sudden be able to leap out in one graceful jump but research did show a gradual rebuilding of vitality which transferred over to a better overall health.

Vitamin E and Diabetics:

In a Swedish Study, Vitamin E therapy as a treatment for diabetes was put forward and supported. The findings includes suggestions such as an advisable daily intake dose of 200 IU of vitamin E over the course of two weeks. The study suggests that Vitamin E helps decrease the insulin requirements of Diabetic patients.

Breast Cancer and Vitamin E: In a society ravaged with an alarming number of women diagnosed with Breast Cancer, vitamin E, taken in proper form appears to be a considered method of reducing the risk of this illness. A number of studies have demonstrated that the risk of contracting Breast Cancer double for women with low levels of vitamin E when compared with those who take the recommended minimum requirements. These studies indicate that some Vitamin E components found in food may be the reason for the reduction in Cancer of the Breast incidence .

There are two classes of Vitamin E:

Tocopherol, the form usually found in supplements
Tocotrienol, found in food. For example palm oil .


Foods rich in Vitamin E are:

Oils: vegetable oils such as palm oil, sunflower, corn, soybean, and olive oil.
Good sources of vitamin e are egg yolk, margarine, Parmesan,cheddar,chickpeas, soya beans, avocados, olives, carrots, parsnips, red peppers, tomatoes, sweet potatoes, sweet corn, and watercress.
Other sources can be found in fish, goats milk, whole grains,wheat or cereal germ, oatmeal, whole grain products peanut butter, fruits, vegetables, milk and all whole raw or sprouted seeds. Because of the hectic life we seemingly lead in this modern world

Did you know?Vitamin E supplements and all Dietary supplements are measured in international units (IU) .

Did you also know that the word 'Vitamin" is the combination of two words proposed by Dr. Cacimir Fun who in 1911 talked about "Vita Amine" when referring to a new food substance used in the cure of beri-beri.

Several decades later, the final "e" was dropped and a new word was created: Vitamin! Vitamins as micro-nutrients were actually discovered earlier (1887) when Dr.Eijkman who was studying a disease in Indonesia called beriberi realized that fowl who were fed with polished rice developed the disease whereas those fed on crudely milled rice did not.

Nutrition has always been the best source for our supplemental needs. Vitamin E is not different and can be found in all the food sources mentioned above. If you choose to take Vitamin E in supplemental form, our best advise would be Organic Vitamins.
