Is drinking alcohol good or bad for your long term health? At first the question might seem quite easy; health institutions, the government, schools and the media often launch public campaigns geared toward reducing excessive alcohol consumption. But while overindulging in alcohol consumption can definitely lead to disastrous consequences, scientists have come to appreciate that moderate alcohol intake can actually promote a healthy heart. So as it turns out, a glass of wine can do much more than simply help us to have a good time if it is consumed in moderation.

These reports are encouraging for both patients and doctors as they combat one of the most common and one of the most lethal cancers in the world. Continue reading
Sulphur dioxide, though used for thousands of years, is still regarded as the most important additive in modern day winemaking. History indicates that the compound was first used by Roman winemakers over 2000 years ago, who recognized that if sulphur candles were first burnt inside empty wine containers, then the wine they held would last longer, keep their colour and not take on a sour vinegar-like taste. Today, sulphur dioxide is usually added in the form of sulphite or bisulphite, and it plays many roles in the making of rich, distinctive wines.
One of the most important uses for sulphur dioxide is to help prevent wine spoilage by bacteria and oxidation. Due to its significant antibiotic and antioxidant properties, the compound is very effective in maintaining wine freshness. Without the additive, wines would only last a few months. Sulphur dioxide’s antimicrobial action is also instrumental is preventing the development of volatile acidity (VA), which is essentially the act of turning wine into vinegar. It accomplishes this by inhibiting the activity of bacteria, yeast and other microbes. While volatile acidity is a part of the fermentation process and has even been described as a part of the character of old Italian wines, too much VA can definitely ruin the flavour and aroma of even the most excellent wines.

As an essential mineral, zinc has been described by doctors K. M. Hambidge and N.F. Krebs as being of “exceptional biological and public health importance.” Biochemical studies have shown that there are several hundred enzymes in the human body which have a zinc atom in the reactive center. Zinc has been linked to increased immune response, reduced risks of cardiovascular diseases and countless others health benefits. The prostate gland contains a high concentration of zinc and the mineral is significantly involved in the reproductive process — particularly the transport of sex hormones in both genders.

For most persons around the world, grapes are a delicious and highly nutritious snack. In fact, grapes are generally considered to be the most important food crop cultivated on planet earth. We pop them into our mouth, spit out the slightly bitter seeds and savor the plump flesh and sweet juices.

As the facts show, by getting rid of the seeds, we have effectively discarded the bulk of the healthy nutrients on offer. Continue reading
Diabetes refers to a group of metabolic diseases in which sufferers have high blood glucose levels due either to inadequate insulin production, failure of the body’s cells to respond to insulin production or both.

The World Health Organization defines obesity as abnormal or excessive fat accumulation that may impair health. It is caused by an energy imbalance between the number of calories consumed and the number of calories used up by the body. The World Health Organization defines overweight person as an individual with a body mass index (a measure of a person’s weight in kilograms divided by the square of his height in meters – kg/m2) greater than or equal to 25, while an obese person by definition has a body mass index (BMI) greater than or equal to 30. Overweight and obesity result in the deaths of 2.8 million adults each year, and are ranked as the fifth leading risk for global deaths. Continue reading
Cognitive decline is regarded by many individuals as one of the most frightening symptoms associated with human aging.

Countless persons have testified that there is no sadder sight than watching someone you love dearly, grow old and slowly lose his or her own identity. Despite the heartache though, most people view such cognitive losses as inevitable – a burden that must be borne by each individual as we enter the twilight years and that there is nothing we can do about it. However, this belief is not true. Continue reading
