Cold Weather May Raise Blood Pressure in Elderly

(HealthDay News) -- When the temperature drops outside, blood pressure appears to rise in older adults, a new study shows.

The systolic (top number) and diastolic (bottom number) blood pressures both rose and fell with the change of seasons in the 8,801 people, aged 65 or older, looked at in the study by the Institut National de la Sante et de la Recherche Medicale of Paris. The average systolic blood pressure, for example, was five points higher in winter than in summer for the participants. Instances of high blood pressure (systolic blood pressure higher than 159, or diastolic higher than 94 millimeters of mercury or higher) were found in 33.4 percent of participants during winter but just 23.8 percent during summer.

The findings were published in the Jan. 12 issue of the Archives of Internal Medicine.

The reasons for the correlation, though, were not known. The authors said it could be related to the baroreflex, a mechanism of blood pressure regulation that is modified in elderly subjects or a function of the sympathetic nervous system, which helps control involuntary actions such as stress response.

Drinking More Fluids Could Lower Men's Bladder Cancer Risk

(HealthDay News) -- Men who drink plenty of low-sugar fluids may reduce their risk for bladder cancer, new research suggests.

Although the reason for the association between fluid intake and protection against cancer remains unknown, researchers theorize the fluids may flush out potential cancer-causing agents before they have a chance to cause any damage.

In conducting the study, Jiachen Zhou, a doctoral candidate in epidemiology at Brown University, and colleagues evaluated the fluid intake of nearly 48,000 men who were part of a long-term study. The men, who were aged 40 to 75 when they enrolled in the study in 1986, answered a questionnaire about their fluid intake every four years for more than two decades.

The investigators found that the men with a high daily fluid intake, or those who drank more than 10 cups (2,531 milliliters) per day, had a 24 percent reduced risk for bladder cancer. The study authors concluded that doctors should tell their patients to drink plenty of low-sugar fluids. Read more…

Avoid Kidney Cancer With Fish Oil, Vitamin D

Almost two years ago, I warned you about the rise in kidney ailments in America while nobody noticed. No surprise, more Americans are dying than ever from kidney cancer, according to University of Michigan researchers, even though early treatment and detection has improved.

Over a 19-year period ending in 2002, kidney cancer diagnoses jumped a startling 52 percent, with the biggest increase seen in patients with smaller tumors (2-4 cm.), making researchers question the effectiveness of their treatments.

A study in the Journal of the American Medical Association, however, suggests gentler, safer way to lower a patient's risk of kidney cancer -- eating fatty fish rich in omega-3 fats and vitamin D -- rather than wasting time on making a better chemotherapy drug. Read more…

Beets detoxify the liver

by: Lenette Nakauchi

The liver is an organ that removes toxins and other harmful substances from the body, allowing the body to function without experiencing the many illnesses and other harmful side effects that these toxins can cause. For this reason, it is crucial that individuals periodically detoxify their livers. One of the most common and effective natural liver detoxifiers is the beet. Beets have been used to fight liver toxins and to increase the overall level of health of individuals for many years, and they can be easily integrated into one`s diet to keep the liver working at an optimal level.

Beets are beneficial to one's health for many reasons, as they are a high-antioxidant vegetable that contains a number of important substances, including: betaine, betalains, fiber, iron, betacyanin, folate, and betanin. Pectin, which is a fiber found in beets, can also help clean the toxins that have been removed from the liver, allowing them to be flushed out of the system instead of reabsorbed by the body. Because of this property, many medical professionals encourage individuals to eat beets raw without juicing them, so that these fibers can be ingested as completely as possible. This is not difficult, as they can be baked, grated, or roasted as well as eaten alone or incorporated into other dishes. Read more…

Top 5 herbs and spices that help lower blood sugar

By Aurora Geib

Fruit, bread, cereals and pasta are popular sources of glucose. Also known as blood sugar, glucose is a vital source of energy for the body. It is constantly required by our muscles and brain. For optimum performance, our brain must have a regular supply on hand because it is incapable of keeping a store for future use. Our muscles, on the other hand, need it for energy when we engage in physical activity.

Carbohydrates are the main source of glucose but the body can also source it from proteins and fats as well. Upon breakdown, these foods are converted and absorbed into the blood. The hormone insulin acts as the key that insures proper absorption of sugar into the cell. In persons suffering from diabetes, there is either insufficient insulin or the body does not produce insulin at all, resulting in increased sugar levels in the blood. Under normal conditions, sugar levels in the blood rise and fall accordingly as glucose is absorbed into the cell producing energy. Read more…
