Red Wine- Good or Bad for Heart?



Red Wine – Good or Bad guy?       
Wine is perhaps the most sophisticated form of alcohol, viewed as an expensive drink to be had sparingly at fancy parties, savored glass by glass.  Red and white wine are extremely different, but there isn’t a set argument as to whether one is better than the other. However, there are rumors that alcohol in small quantities - specifically red wine - may actually benefit your health. You’ve heard about how excessive drinking is bad for your health; it causes liver damage, inhibits your senses, and can lead to poor decisions and life-altering accidents.  Binge drinking every night is not encouraged, but rather warned against.  
Increase in good Cholesterol
As a result of the grapes used in creating it, red wine contains antioxidants, which counteract the effect of oxidation.  Such antioxidants may be able to either increase the consumer’s level of ‘good’ cholesterol, or lower the level of ‘bad’ cholesterol.  These antioxidants may also help protect against damage to the arteries of the heart, thereby reducing the risk of heart disease. 

Resveratrol, the magic content
A particular antioxidant called resveratrol is responsible for this, as it helps protect the lining of blood vessels in the heart. Resveratrol is found in red grape skin, which is perhaps why it is said red wine specifically - not white - has more health benefits.  It is supposed that resveratrol could work by helping to activate a protein that helps prevent heart inflammation, keeping the heart healthier.  Some have also begun to speculate that resveratrol might even prevent fat cells from maturing fully, which could prevent obesity.  Resveratrol is often sold as a supplement in capsule form.
Advertisements for such supplements claim that resveratrol helps with weight loss, and may even contain anti-aging properties.  These statements are currently being disputed, as scientists are not entirely sure what properties resveratrol possesses.  A few of the supposed benefits include prevention of blood clots that could lead to a heart attack, limitation of the spreading of cancer cells, protection of nerve cells from plaque buildup that could lead to Alzheimer’s, and prevention of diabetes through prevention of insulin resistance. 
French Paradox      
Some support in the theory that red wine prevents heart disease can be found in what has been called the ‘French paradox.’  The French diet consists of many foods high in saturated fat; however, less of the French people die as a result of heart disease than do people in countries with a lower intake of saturated fat.  Although it has never been proven that French consumption of red wine is the cause, many people suspect that wine is the solution.
A study in Copenhagen, in which over thirteen thousand men and women were observed over the course of twelve years, suggested that those who drink red wine halve their risk of dying from stroke or heart disease.  While some studies have shown similar results, others have not; red wine’s benefits have not been proven to be completely true.
No concrete evidence
Although there have been studies that seem to prove that red wine really is beneficial to your health, there still isn’t much concrete evidence.  What could seem to be the work of red wine could, in fact, be induced by other foods in people’s diets, or other aspects of their daily lives.  Someone who exercises regularly and eats healthily, for example, is less at risk for stroke or heart disease than someone who dose not exercise and consumes large quantities of unhealthy food.
Limit your drink
Even if red wine proves to be beneficial to the health of your heart, too much of it can be harmful.  Overindulgence in alcohol not only affects the liver, it affects the brain, heart, immune system, and pancreas as well.  Even though you may drink red wine to try and make your heart healthier, you could seriously damage it.  Excessive drinking - whether it be in a short period or over time - can cause the heart muscle to stretch or droop, and can make your heartbeat irregular.  Too much alcohol also increases your blood pressure and your risk of stroke. American heart association recommends no more than 2 drinks for male and 1 drink for females and elderly. Pregnant patients should not take alcohol.
It’s a fine line between drinking for health and overdoing it, and wine is not a superdrink.  Red wine will not cure your heart problems, nor will it extremely decrease your risk of heart disease or stroke.  Red wine is only a stepping-stone at most, a little nudge in the right direction for your body.  It is not something to be relied on, and overindulgence can really hurt your body.  So although you may be curious to experiment, to see if the theories about antioxidants and red wine’s power are really true, beware.  Don’t overdo it, and always play it safe.

Obesity and your heart


Obesity – One of the worst epidemics around!
Obesity is a disease that has the potential to wreak havoc in one’s life as it leads to various diseases such as heart attack, diabetes, sleep apnea and high blood pressure. There are about 60 million people in the United States who suffer from it. Studies suggest that more than one-third of women whose ages are between 20 and 74 tend to be obese. The reason? Well, the increased inclination towards eating pre-packaged foods, fast foods, junk foods and our hectic lives not making it possible for us to live an active life!

So, how can obesity be defined? People typically tend to think of the term ‘obese’ as just being excessively fat or overweight. To be honest, nothing could be farther from the truth. The basic difference between being overweight and being obese is that overweight individuals typically weigh more because of the excessive weight of their bone, fat, muscle and water components of the body. On the other hand, obese individuals have surplus amounts of body fat.

So how do we know that a person is obese?
Well, a majority of healthcare professionals claim that men who have more than 25 percent body fat are to be considered as being obese. However, women who have over 30 percent body fat are the ones who are obese. The reason why there is a difference in terms of this particular percentage is because women tend to physiologically have far more body fat as compared to men.

Obesity and its statistics
Speaking on a global level, there are about 1 billion overweight individuals all over the world, and about 300 million of them are considered as being clinically obese! Moreover, it is believed that the highest affected by obesity are Non-Hispanic blacks, who account for around 49.5% of all obese people. Obesity also affects 39.1% Hispanics and 34.4% of non-Hispanic whites.

Believe it or not, but obese individuals spend nearly $147 billion each year to get treated! Back in the year 2008, the medical expenses that people who were obese had to cover equalled nearly $1,429 more than those of normal weight individuals.

Know your Numbers
Sedentary lifestyle has increased the incidence of obesity. Obesity has been defined as a BMI greater than 30 kg/m2. What is BMI? BMI is body mass index that can be calculated by dividing your weight over your height in meters.
Definitions
        Underweight = <18
        Normal weight = 18.5–24.9
        Overweight = 25–29.9
        Obesity = BMI of 30 or greater

You can check your BMI through National Heart, lung and Blood Institute website. The link is

According to National Heart, Lung and Blood Institute “If most of your fat is around your waist rather than at your hips, you’re at a higher risk for heart disease and type 2 diabetes. This risk goes up with a waist size that is greater than 35 inches for women or greater than 40 inches for men. To correctly measure your waist, stand and place a tape measure around your middle, just above your hipbones. Measure your waist just after you breathe out.”

The connection between obesity and heart diseases
The development of cardiovascular diseases is largely associated with being obese. The worst part is that as you continue to gain body fat, the chances of you developing a heart disease increase as well.

Obesity normally triggers development of high blood pressure, which is obviously going to damage your arteries, thereby leading to atherosclerosis or hardening of the arteries. The worst part is that hypertension additionally has the tendency to damage your kidneys, and leave a severe impact over your heart as well. The increased amounts of blood that needs to be pumped out by the heart means that it needs to work extra hard to make sure that the body receives ample amounts of blood. This, in the long term, is going to lead to heart failure. More importantly, obesity triggers Type 2 diabetes, which is one of the most well-known and acknowledged causes of heart disease.

Obesity
-       Increases the bad cholesterol, the LDL
-       Decreases the good cholesterol, the HDL
-       Increase the risk for diabetes
-       Increase the blood pressure
-       Increases the risk for sleep apnea

Treatment of obesity – How to lose weight and live a healthier life
There isn’t single prescription that can help you lose weight and live a better life. However, you would need to try out several different things simultaneously, which, over time, are going to make it possible for you to lose weight. Some of them are:

Take reduced salt diet
The first thing that you need to do is stop eating things that are salty. The reason is that this will make it possible for you to eliminate water retention by losing out the accumulated water in your body. This also reduces the chances of you developing high blood pressure.

Don’t skip meals, particularly your breakfast
You must not skip meals, and it is necessary for you to have your breakfast as well. The reason is that a nutritious breakfast is going to enhance your metabolic processes, allowing you to remain active all through the day.

Calories, Calories and Calories
Calories are most important than the type of diet. You need to burn more calories than what you eat or drink. Have a food diary and calculate the calories that you ate. Then calculate how many calories you burn in a day.

Weight loss = calories lost in a day          
                       =  Total calories intake (food, snacks & drinks) – Total calories spent in a day

If you have a negative balance, you are towards the path to success. Keep a diary for success.

Quit alcohol and sodas
This one is self-explanatory – you need to quit your consumption of high calorie alcoholic drinks such as beer and sodas right away, as these are significant triggers of obesity.

Exercise as much as possible
For you to lose weight; it is necessary to exercise on a regular basis. Join the gym, head out for jogging sessions, work out at home – all of these will make it easier for you to cut down on those accumulated fats!
Aim for losing 2 pounds every week as a drastic weight loss is not recommended and in long term lost pounds will be back again

Medications to lose weight
The only Food and Drug Administration (FDA) approved drug available currently is Orlistat. Orlistat has been shown to reduce 5 to 10 pounds in a year but it can cause flatulence and bloating.

Surgery to lose weight
There are two types of surgery available gastric banding and gastric bypass. These surgeries reduce the size of the stomach to about ½ a cup and also can decrease the appetite. They can reduce up to 80 pounds of weight in a year. Surgery is usually an option for morbidly obese individuals with a BMI greater than 35.
