Drink To Your Health

[media id=15 width=500 height=400]

Scientists have found a substance in red wine that is slowing down the aging process in mice. Will it someday lengthen the lives of humans, too? Morley Safer reports.

Ingredients

Generally energy drinks include methylxanthines (including caffeine), vitamin B and herbs. Other common ingredients are guarana, acai, and taurine, plus various forms of ginseng, maltodextrin, carbonated water, inositol, carnitine, creatine, glucuronolactone and ginkgo biloba. Some contain high levels of sugar, and many brands also offer artificially-sweetened ‘diet’ versions. The central ingredient in most energy drinks is caffeine, the same stimulant found in coffee or tea, often in the form of guarana or yerba mate.

The average 237 milliliter (8 fluid ounce) energy drink has about 80 mg of caffeine, with 480 mL (16 fl. oz.) drinks containing around 150 mg.

Desirable effects

A variety of physiological and psychological effects attributed to energy drinks and/or their ingredients have been investigated.

Two studies reported significant improvements in mental and cognitive performances as well as increased subjective alertness. Excess consumption of energy drinks may induce mild to moderate euphoria primarily caused by stimulant properties of caffeine and may also induce agitation, anxiety, irritability and insomnia. During repeated cycling tests in young healthy adults an energy drink significantly increased upper body muscle endurance. It was also suggested that reversal of caffeine withdrawal is a major component of the effects of caffeine on mood and performance.

Restorative properties were shown by a combination of caffeine and the sugar glucose in an energy drink, and some degree of synergy between the cognition-modulating effects of glucose and caffeine was also suggested. In one experiment, a glucose-based energy drink (containing caffeine, taurine and glucuronolactone) was given to eleven tired participants being tested in a driving simulator. Lane drifting and reaction times were measured for two hours post-treatment and showed significant improvement.

Two articles concluded that the improved information processing and other effects could not be explained in terms of the restoration of plasma caffeine levels to normal following caffeine withdrawal.

Adverse effects

Caution is warranted even for healthy adults who choose to consume energy beverages. Consumption of a single energy beverage will not lead to excessive caffeine intake; however, consumption of two or more beverages in a single day can. Other stimulants such as ginseng are often added to energy beverages and may enhance the effects of caffeine, and ingredients such as guarana themselves contain caffeine. Adverse effects associated with caffeine consumption in amounts greater than 400 mg include nervousness, irritability, sleeplessness, increased urination, abnormal heart rhythms (arrhythmia), and stomach upset. The concentration of sugar in a sports drink is recommended to be 6-7% carbohydrate to allow maximum absorption and minimize spikes and crashes in blood sugar. Higher concentrations such as those seen in energy drinks will slow fluid absorption into the blood and energy system, increasing the possibility of dehydration. When a high level of sugar is in the blood stream the body cannot get the water into the cells that it needs because the water is busy trying to dilute concentration of sugar in the blood stream. The actual number of people suffering from adverse effects is difficult to measure since many cases go unreported.

In the United States, energy drinks have been linked with reports of nausea, abnormal heart rhythms and emergency room visits.The drinks may cause seizures due to the “crash” following the energy high that occurs after consumption.Caffeine dosage is not required to be on the product label for food in the United States, unlike drugs, but some advocates are urging the FDA to change this practice.

Until 2008, France banned the popular energy drink Red Bull after the death of eighteen-year-old Irish athlete Ross Cooney, who died as a result of playing a basketball game after consuming four cans of the drink The French Scientific Committee (J.D. Birkel) concluded that Red Bull has excessive amounts of caffeine. Denmark also banned Red Bull. Britain investigated the drink, but only issued a warning against its use by pregnant women and children.

Heart valve surgery – operation for replacement heart valves

[media id=83 width=500 height=400]

heart valves maintain the unidirectional flow of blood in the heart by opening and closing depending on the difference in pressure on each side. They are mechanically similar to reed valves.

Atrioventricular valves

These are small valves that prevent backflow from the ventricles into the atria during systole. They are anchored to the wall of the ventricle by chordae tendineae, which prevent the valve from inverting.

The chordae tendineae are attached to papillary muscles that cause tension to better hold the valve. Together, the papillary muscles and the chordae tendineae are known as the subvalvular apparatus. The function of the subvalvular apparatus is to keep the valves from prolapsing into the atria when they close. The subvalvular apparatus have no effect on the opening and closure of the valves, however. This is caused entirely by the pressure gradient across the valve.

The closure of the AV valves is heard as the first heart sound

Echocardiography — The echocardiogram is an ultrasound of the heart. Using standard ultrasound techniques, two-dimensional slices of the heart can be imaged.

Heart — The heart is a hollow, muscular organ in vertebrates that pumps blood through the blood vessels by repeated, rhythmic contractions, or a similareart. Veins form part of the circulatory system. The vessels that carry blood …

Vein — In biology, a vein is a blood vessel which carries blood toward the heart. Veins form part of the circulatory system

The tricuspid valve is the three flapped valve on the right side of the heart, between the right atrium and the right ventricle which stops the backflow of blood between the two. It has three cusps.

Semilunar valves

These are located at the base of both the pulmonary trunk (pulmonary artery) and the aorta, the two arteries taking blood out of the ventricles. These valves permit blood to be forced into the arteries, but prevent backflow of blood from the arteries into the ventricles. ^[1] These valves do not have chordae tendineae, and are more similar to valves in veins than atrioventricular valves.

Aortic valve

Main article: aortic valve

The aortic valve lies between the left ventricle and the aorta. The aortic valve has three cusps. During ventricular systole, pressure rises in the left ventricle. When the pressure in the left ventricle rises above the pressure in the aorta, the aortic valve opens, allowing blood to exit the left ventricle into the aorta. When ventricular systole ends, pressure in the left ventricle rapidly drops. When the pressure in the left ventricle decreases, the aortic pressure forces the aortic valve to close. The closure of the aortic valve contributes the A2 component of the second heart sound (S2).

The most common congenital abnormality of the heart is the bicuspid aortic valve. In this condition, instead of three cusps, the aortic valve has two cusps. This condition is often undiagnosed until the person develops calcific aortic stenosis. Aortic stenosis occurs in this condition usually in patients in their 40s or 50s, an average of over 10 years earlier than in people with normal aortic valves.

Pulmonary valve

Main article: pulmonary valve

The pulmonary valve (sometimes referred to as the pulmonic valve) is the semilunar valve of the heart that lies between the right ventricle and the pulmonary artery and has three cusps. Similar to the aortic valve, the pulmonary valve opens in ventricular systole, when the pressure in the right ventricle rises above the pressure in the pulmonary artery. At the end of ventricular systole, when the pressure in the right ventricle falls rapidly, the pressure in the pulmonary artery will close the pulmonary valve.

The closure of the pulmonary valve contributes the P2 component of the second heart sound (S2). The right heart is a low-pressure system, so the P2 component of the second heart sound is usually softer than the A2 component of the second heart sound. However, it is physiologically normal in some young people to hear both components separated during inhalation.

Healthy Eating

[media id=6 width=500 height=400]

Healthy Eating makes you feel better and look better. This video by syndicated columnist Rita Heikenfeld shows you recipes, cooking tips and is a guide to healthy eating.

For an overall eating plan, consider the DASH eating plan. “DASH” stands for “Dietary Approaches to Stop Hypertension,” a clinical study that tested the effects of nutrients in food on blood pressure. Study results indicated that elevated blood pressures were reduced by an eating plan that emphasizes fruits, vegetables, and lowfat dairy foods and is low in saturated fat, total fat, and cholesterol. The DASH eating plan includes whole grains, poultry, fish, and nuts and has reduced amounts of fats, red meats, sweets, and sugared beverages.

A second clinical study, called “DASH-Sodium,” looked at the effect of a reduced dietary sodium intake on blood pressure as people followed either the DASH eating plan or a typical American diet. Results showed that reducing dietary sodium lowered blood pressure for both the DASH eating plan and the typical American diet. The biggest blood pressure-lowering benefits were for those eating the DASH eating plan at the lowest sodium level (1,500 milligrams per day).

The DASH-Sodium study shows the importance of lowering sodium intake whatever your diet. But for a true winning combination, follow the DASH eating plan and lower your intake of salt and sodium.
