  Ten Surprising Health Benefits of Beer.

Day in Health

Beer drinkers rejoice: Your favorite brew may be healthier than you think. For years, wine drinkers have indulged without guilt, reveling in the news that red wine can help protect against heart disease. Recent research shows that beer can also be good for what ails youfrom reducing risk for broken bones to helping warding off diabetes and mental decline. It can even increase longevity, a large study suggests. However, the key to tapping into beer’s benefits is moderation, meaning just one 12-ounce beer per day for women and two for men. Heavy drinking ups the threat of liver damage, some cancers, and heart problems. Bingeing on brew skis can also make you fat, since a 12-ounce regular beer has about 150 calories, while light beer has about 100.
Here are 10 surprising—and healthy—reasons to cheer about your next beer.
 1. Stronger Bones
Beer contains high levels of silicon, which is linked to bone health. In a 2009 study at Tufts University and other centers  older men and women who swigged one or two drinks daily had higher bone density, with the greatest benefits found in those who favored beer or wine. However, downing more than two drinks was linked to increased risk for fractures.
For the best bone-building benefits, reach for pale ale, since a 2010 study of 100 types of beer from around the word identified these brews as richest in silicon, while light lagers and non-alcoholic beers contained the least.
 2. A Stronger Heart
A 2011 analysis of 16 earlier studies involving more than 200,000 people, conducted by researchers at Italy’s Foundation di Ricerca e Cura, found a 31 percent reduced risk of heart disease in those who quaffed about a pint of beer daily, while risk surged in those who guzzled higher amounts of alcohol, whether beer, wine, or spirits.
More than 100 studies also show that moderate drinking trims risk of heart attacks and dying from cardiovascular disease by 25 to 40 percent, Harvard reports. A beer or two a day can help raise levels of HDL, the “good” cholesterol that helps keep arteries from getting clogged.
 3. Healthier Kidneys
A study in Finland singled out beer among other alcoholic drinks, finding that each bottle of beer men drank daily lowered their risk of developing kidney stones by 40 percent. One theory is that beer’s high water content helped keep kidneys working, since dehydration increases kidney stone risk.
It’s also possible that the hops in beer help curb leeching of calcium from bones; that “lost” calcium also could end up in the kidneys as stones.
4. Boosting Brain Health
A beer a day may help keep Alzheimer’s disease and other dementia at bay, researchers say.
A 2005 study tracking the health of 11,000 older women showed that moderate drinkers (those who consumed about one drink a day) lowered their risk of mental decline by as much as 20 percent, compared to non-drinkers. In addition, older women who downed a drink a day scored as about 18 months “younger,” on average, on tests of mental skills than the non-drinkers.
5. Reduced Cancer Risk
A Portuguese study found that marinating steak in beer eliminates almost 70 percent of the carcinogens, called heterocyclic amines (HCAs) produced when the meat is pan-fried. Researchers theorize that beer’s sugars help block HCAs from forming.
Scientists also have found that beer and wine contain about the same levels of antioxidants, but the antioxidants are different because the flavonoids found in hops and grapes are different.
6. Boosting Vitamin Levels
A Dutch study, performed at the TNO Nutrition and Food Research Institute, found that beer-drinking participants had 30 percent higher levels of vitamin B6 levels in their blood than their non-drinking counterparts, and twice as much as wine drinkers. Beer also contains vitamin B12 and folic acid.
7. Guarding Against Stroke
Researchers at the Harvard School of Public Health found that moderate amounts of alcohol, including beer, help prevent blood clots that block blood flow to the heart, neck and brain—the clots that cause ischemic stroke, the most common type.
8. Reduced Risk for Diabetes
Drink up: A 2011 Harvard study of about 38,000 middle-aged men found that when those who only drank occasionally raised their alcohol intake to one to two beers or other drinks daily, their risk of developing type 2 diabetes dropped by 25 percent. The researchers found no benefit to quaffing more than two drinks. The researchers found that alcohol increases insulin sensitivity, thus helping protect against diabetes.
9. Lower Blood Pressure
Wine is fine for your heart, but beer may be even better: A Harvard study of 70,000 women ages 25 to 40 found that moderate beer drinkers were less likely to develop high blood pressure—a major risk factor for heart attack—than women who sipped wine or spirits.
10. Longer Life
In a 2005 review of 50 studies, the U.S. Department of Agriculture (USDA) reported that moderate drinkers live longer. The USDA also estimates that moderate drinking prevents about 26,000 deaths a year, due to lower rates of heart disease, stroke, and diabetes.
These benefits appear to apply in other countries as well, with an earlier study reporting that, “if European beer drinkers stopped imbibing, there would be a decrease in life expectancy of two years and much unhappiness.”

Hidden Effects of SMOKING





Cigarette smoking:
Many people are aware of the dangers to the lung cancer, chronic obstructive pulmonary disease (COPD) and cardiovascular disease but it can also cause slow, less noticeable damage to many other organs and body systems and your marital life too.
Smoking not only affects lungs but also gives rise to infertility problems. Smoking damages sperm, making them less likely to fertilize eggs and making the embryos they do manage to create less likely to survive.
Human sperm cells carry, balanced, two tiny highly charged proteins called protamine 1 and protamine 2. In smokers, sperm cells carry too little protamine 2. This imbalance makes them highly vulnerable to DNA damage. "When we inject these damaged sperm into an egg cell, the sperm is not capable of fertilizing the cell. And even if it does, the [miscarriage] rate is very high."  The quality of sperm from study subjects was assessed on the basis of density (number), motility, and morphologic abnormalities. Spermatozoa from smoker’s possessed significantly decreased density and motility compared with non-smokers (p 0.001). 75% of smokers versus 26% of non-smokers had a sperm density under 40 x 10 million/ml.
  Smoking cigarettes affects a man’s ability to maintain his erection. Erection occurs when there is a swift flow of blood to the penis. If something interferes with the blood flow, such as chemicals released during smoking, flow of blood may drop. There are also long-term effects such as endothelial dysfunction, which means a breakdown in the normal biochemical processes carried out by the cells lining the inner surface of the blood vessels. Long-term smoking has an effect on marital relations.
One of the main impacts of smoking is a decrease in lung function. The lungs consist of delicate membranes which are able to filter oxygen out of the air and send it into the bloodstream. Oxygen is essential for muscle function, especially during exercise, when muscles demand more oxygen, this means a decrease in stamina and performances, as muscles that get inadequate oxygen become fatigued more quickly.

Smoking also decreases your brain's performance, making you less effective in your work.
The effects of smoking on your face will make you seem older than you actually are, affecting your social life.
Smoking can affect your hearing. It has long been known that active smoking produces a negative effect on middle ear function.
Smoking increases your blood pressure too.

Women are more at risk from smoking
 Men and women are equally susceptible to the damage caused by chemicals in cigarettes. For women, cigarette smoking increases the risk of a number of specific health problems. Women who smoke can experience irregular periods and secondary amenorrhea (absence of menstruation);

Misconception on Smoking and Relaxation

 Many smokers claim that they smoke for relaxation. In fact, part of the relaxing effect of smoking a cigarette results from deep breathing. Try inhaling as if you had a cigarette in your mouth. Hold that breathe briefly and slowly exhale. Such deep breathing, pumps up to 20 percent more oxygen to the brain.
 

The Aftermath if you quit today:

Even if you have been smoking heavily for many years, it would still be in your best interest to quit. Quitting smoking can reverse the harmful processes begun by cigarette smoke and prevent the further deterioration of your body.
