Chocolate– The Newest Health Food?

Tags: , , , , ,


There are now even more reasons for chocolate lovers to rejoice! As more amazing research news comes in about chocolate, the substance is moving from a bad-for-you candy to an important health food. Those of us who had always continued to indulge in occasional chocolate treats can stop feeling guilty and now easily justify our cravings.

You may have already heard that chocolate contains beneficial flavonoids and antioxidents. Flavonoids are naturally-occurring compounds found in plant foods that are full of recognized health benefits. There are more than 4,000 flavonoid compounds, which are a subgroup of a large class called polyphenols. Phenols are believed to help reduce the risk of heart disease by helping prevent atherosclerosis. The flavanols in chocolate appear to help the body use nitric oxide, which is crucial for healthy blood flow and blood pressure, which means that chocolate might help reduce hypertension as well.

Red wine is know for its high phenol content, but an average bar of dark chocolate contains more phenols than 8 ounces of red wine. Scientists at Cornell University and Seoul National University examined the cancer-fighting antioxidant content of hot cocoa, red wine, and tea, and found that cocoa had nearly double the antioxidants of red wine and four to five times more than tea.

Holland’s National Institute of Public Health and Environment found that dark chocolate contains 53.5 mg of catechins per 100 grams. Catechins are the powerful antioxidants that fight against cancer and help prevent heart disease. By contrast, a cup of black tea contains only about 14 mg of catechins and green tea has about 30 mg of catechins.

A study at University of California Davis found that participants who ate chocolate showed a reduction in platelet activity. This means that chocolate has an anti-clotting, blood-thinning effect that can be compared to aspirin.

A Harvard University study of 8,000, with an average age of 65, revealed that those who consumed chocolate lived almost a year longer than those who did not. Those who ate one to three candy bars per month had a 36 percent lower risk of death compared to the people who ate no candy, while those who ate three or more candy bars per week had a 16 percent lower risk.

A study of older men in The Netherlands, known for its chocolate, showed that those who ate the most chocolate, an equivalent of one-third of a chocolate bar every day, had lower blood pressure and a 50 percent lower risk of death. The researchers also noted the men eating the most cocoa products were not heavier or bigger eaters than the men who ate less cocoa.

And it’s not just dark chocolate that is the only healthy type of chocolate. Most studies talk about the benefits of dark chocolate, but some of the most recent news about chocolate includes good news for milk chocolate lovers, who have been left out in the past.

The Wheeling Jesuit University in West Virginia did a study that shows that milk chocolate seems to boost brainpower. The groups in the test consumed, on different occasions, milk chocolate, dark chocolate, carob and nothing. Then they were tested for cognitive performance including memory, attention span, reaction time, and problem solving.

According to Dr. Bryan Raudenbush, “Composite scores for verbal and visual memory were significantly higher for milk chocolate than the other conditions.” The study also found that consumption of milk and dark chocolate was associated with improved impulse control and reaction time. It seems that by consuming chocolate you get stimulating effects from substances found in chocolate, such as theobromine and phenylethylamine, which then lead to increased mental performance.

Chocolate really does make you feel good, too. It is known to stimulate the secretion of endorphins, producing a pleasurable sensation similar to the “runner’s high” a jogger feels after running several miles. Chocolate also contains a neurotransmitter, serotonin that acts as an anti-depressant. Studies in England show that even the aroma of chocolate gives a bout of euphoria and will help lift the spirits.

And now people are looking at chocolate for skin care. According to Marlies Spinale, director of Tru Spa, “Like many other antioxidants, cocoa polyphenols are thought to offer the skin protection from free-radical damage caused by sun, pollution, stress, alcohol consumption and other factors. I believe that we will hear more about the benefits of chocolate in skin care.”

Some people have been avoiding chocolate because one of the main ingredients of chocolate is cocoa butter. It was thought that it was an unhealthy fat, but actually cocoa butter is not unhealthy. It is made up of the beneficial fatty acids– oleic acid a heart-healthy monounsaturated fat also found in olive oil, stearic and palmitic acids. Stearic and palmitic acids are healthy forms of saturated fat. Plus chocolate contains vitamins A, B1, C, D, and E, as well as potassium, sodium, and iron.

So go ahead and indulge in a little chocolate, in moderation of course. I would recommend that you try to find organic chocolate, and stick with darker chocolate because it has more chocolate flavonoids and less sugar. Sugar weakens the immune system; so don’t consume sugar if you are ill. And a little bit of milk chocolate is alright when you need an occasional milk chocolate brainpower boost, such as before a test. All you students take note!

Online health supplements

Tags: , , ,


The internet, a relatively new invention, presents us with new ways to make the purchases of items we need. Another relatively new craze would have to be the worlds obsession with health supplements. In an increasingly health-aware society, there are many easy options out there to help keep your health robust. Many of them are offered online, and here is a quick primer on some of the online health supplements offered

Coral calcium This supplement is a great choice to help your body develop properly. You probably know that your body needs calcium to maintain its bones and teeth, but most people dont realize that you need a certain level of calcium in your bloodstream as well. If you dont keep replenishing this calcium, your body will begin to sap the calcium from your bones and teeth to maintain the level in your blood. This can result in bone and teeth shrinkage, and can make them brittle and cause movements to be painful.

Coral calcium is a source of calcium that surpasses most of the others in terms of absorption and lack of side-effects. Available in online health supplements, coral calcium can be a great buy.

DMAE A substance that can be found in high concentrations in anchovies and sardines. In addition, the human brain also produces a trace amount of DMAE. Throughout the years, it has been widely acclaimed that this wonderful nutrient can be of help to those with hyperactivity or attention deficit hyperactivity disorder. Also, it has been conjectured that DMAE helps to treat memory lapses and Alzheimers disease. When this substance is harvested from the bodies of fish, it is purified and concentrated and offered in online health supplements.

Also, it can be very important to get all the vitamins your body needs. On a daily basis, it is important for our body to receive proper levels of Vitamin A, Vitamin B complex, Vitamin C, Vitamin D, Vitamin E, and Vitamin K. These can often be found together in a simple pill form, and there are plenty of online health supplements that offer all of these vitamins and more in a simple format.

Supplements for Athletes in Training

Tags: ,


One common misconception that people have regarding exercise is that performing it on a regular basis will prevent them from developing any health problems. When you exercise, your body uses its nutrients to fuel the energy necessary to perform the exercise. Depending on the intensity of your workout and the amount of nutrients in your body, you can actually put yourself at risk for nutrient deficiency, which can result in infections. This is especially true for athletes during training.

Consuming sufficient amounts of nutrients is an important concern for everyone. The more physical demands you place on your body the more nutrients it requires. Consuming more foods that contain essential vitamins and minerals to compensate for the stress on the body may seem to make sense. However, the demands of a strenuous training routine make it nearly impossible to consume a sufficient amount. Vitamin supplementation can help create the stores of nutrients that you need to achieve your training goals successfully.

Many of the vitamins that your body uses during an intense workout are antioxidants. It is important that you maintain adequate amounts of these in your system because they keep infections at bay. Vitamins C and E are two of the most beneficial antioxidants for athletes in training. These vitamins not only prevent infection, but they help to enhance your stamina so that you can endure the intense workout. In addition, vitamins C and E can help rebuild muscle tissue that suffers minor damage during a hard workout. You should not rely on vitamins alone, but be sure to eat protein and carbohydrates in between your workouts, which can also help to rebuild the amount of glycogen you lose during your workout.

The amount of vitamin C supplements an individual should take varies, but should not exceed 1000 milligrams. Excessive amounts of vitamin C are not considered toxic because the nutrient is water-soluble and excess is excreted in the urine. However, consuming more than 1000 milligrams can cause nausea and diarrhea. If you are considering taking vitamins E supplements, you don’t want to take more than 200 milligrams. There are varying reports on the effects of excessive vitamin E so you should discuss taking this vitamin with your doctor.

Vitamin B-2

Riboflavin is a common name for vitamin B-2 and was once known as Vitamin G. You will see Vitamin B-2 described as Riboflavin on the back of vitamin bottles and in other food packaging.

An interesting and curious fact about Riboflavin is that it is naturally produced by the bacteria in your gut. Although it may not be produced in sufficient quantities to prevent deficiencies. Intestinal production, however, can reduce the symptoms of a deficient state.

Some experts claim that B-2 deficiency is the most prominent nutrient deficiency in North America. Those who eat a diet largely constructed of refined and fast foods may be at risk. And of course, alcoholics are at higher risk of B vitamin deficiencies. Low-income individuals may also tend to be at higher risk due to diet.

Problems with blood proteins may lead to deficiency. And states that block or reduce the uptake of riboflavin into the cell can also be responsible for a deficient state. Therefore, just having an adequate supply of Riboflavin in your food does not necessarily preclude deficiency.

Brewer’s yeast and organ meats are sources that are high in Riboflavin. Lower amounts may be found in milk, eggs, green leafy vegetables and some fruits.

As a side note, I once had a biochemistry teacher whom offered two pieces of advice to his students. He told us to drink a gallon of water per day and to take some brewer’s yeast every day. As I remember it, he talked about how brewer’s yeast was excellent food for the cellular processes of the body. That was probably due to the fact that brewer’s yeast is an excellent source of the b vitamins.

Drinking a gallon of water per day was slightly unusual advice as most experts and nutritionists agree that 2 liters is an adequate intake. This biochemistry teacher was recommending twice that amount. Remember to consult with a physician before changing your diet, supplement or water intake.

Riboflavin is very important in cellular metabolism, the process by which your body produces usable energy. It is important in forming the coenzymes that are necessary to make ATP, which is the energy currency of the cells.

A partial list of deficiency symptoms include fatigue, sensitivity to light and dermatitis. Nerve tissue damage and retarded growth in infants and children can result from a deficiency.

More detailed and technical information about Riboflavin can be found at emedicine.com. If you have any doubts about your health as it relates to Riboflavin, ask your doctor for a proper diagnoses and treatment. Each human body is different with different needs and contraindications, that is why it is important to consult your physician.

Vitamins and Interactions

Tags: , ,


Vitamins are good for you, so it stands to reason that getting all the vitamins you can everyday is the best course of action. As a general rule, its true that choosing foods rich in vitamins is a good idea. But there are times when more isnt better, even when it comes to vitamins.

The first thing to keep in mind is that several vitamins have toxic levels. In other words, there is a point at which consuming more vitamins is not only unhelpful, it can be dangerous.

Vitamin K helps the body clot blood. If you get a cut, your bloods natural tendency to clot will keep you from bleeding to death. But there are some people who have blood that clots too readily, or who have health issues that require thinner blood. Some people with specific types of heart problems may actually be on medication designed to thin the blood. Doctors may also prescribe a blood thinner for a patient getting ready for some types of surgeries. If thinning the blood is your doctors goal, taking a Vitamin K supplement or eating foods that are particularly rich in Vitamin K may be dangerous.

If youre taking an aspirin each day, your body may be experiencing a Vitamin C deficiency. Studies have indicated that Vitamin C is typically absorbed by blood cells, but aspirin in the system may block this normal absorption action.

If you need more iron in your body, you may want to consider increasing the amount of Vitamin C in your daily food intake. It seems that having enough Vitamin C in your system makes your body more readily absorb iron, tackling that anemia problem more quickly than taking iron alone.

If youre taking antibiotics, particularly over a long period of time, your body may have trouble absorbing sufficient amounts of Vitamin A. If youre taking drugs to lower your cholesterol, you may also experience Vitamin A deficiency.

Vitamin E and Zinc work hand-in-hand. If your body has lower-than-normal levels of Zinc, you may also have a Vitamin E deficiency, even if youre eating healthy. Vitamins C and E also work together.

There are a number of other interactions that can occur between vitamins, or between vitamins and other conditions, minerals and drugs. Remember that it is possible to overdose on some vitamins, and some can cause serious problems with medication, diet and existing health problems. Its best to talk to a health care professional before you start or alter your daily diet or vitamin intake.

All about vitamin A

Tags: , , ,


Vitamins are essential for good health and well being. They are defined as any group of substances required in small quantities for healthy growth and development. They cannot be manufactured in the body so they are therefore vital constituents of the diet.

There are two types of vitamins according to whether they are soluble in water or fat. Vitamin A Retinol is a fat soluble vitamin and this is not excreted from the body in the urine so excessive intake can have a negative effect on health. Vitamin A is present in animal origin foods eg. liver, milk and egg yolk. It is formed in the body from the pigment Beta-carotene which is present in certain vegetables eg. carrots, cabbage and lettuce.

Vitamin A has a number of roles in the body. It is necessary for normal cell division and growth. It is important for maintenance of mucous membranes of the repiratory, digestive and urinary tracts. Retinol is a pale yellow solid which dissolves easily in oil and fat and it is essential for good eye sight, particularly vision in dim light as well as having an important role in normal development of the embryo. It can be produced synthetically and therefore used to enrich margarines.

The best source of retinal is liver and a small amount 3g meets the bodys daily requirements. 700mcg per day is a sufficient amount per adult which can also be derived from the beta carotene foods eg. 2oz raw carrots.

Deficiency of Vitamin A causes stunted growth, night blindness and drying up of mucous membranes which increases the risk of infection. A continued lack of Vitamin A can lead to worsening of vision an
