New Research shows that Alcohol can Protect against Heart Disease

Individuals who drink alcohol in moderation are 14-25% less likely to develop heart disease

Individuals who drink alcohol in moderation (about one drink a day or less) are 14-25% less likely to develop heart disease compared to those who drink no alcohol at all, finds research led by Professor William Ghali from the University of Calgary, published on bmj.com today.


The first paper, led by Paul Ronksley from the University of Calgary, emphasises that a balance needs to be found between the public health message that consuming large amounts of alcohol is bad for you, and the one that drinking in moderation can have health benefits.

An accompanying paper led by Dr Susan Brien, also from the University of Calgary, finds that moderate consumption of alcohol (up to one drink or 15 g alcohol per day for women and up to two drinks or 30 g alcohol per day for men) is good for health. They say moderate amounts of alcohol significantly increase the levels of ‘good’ cholesterol circulating in the body and this has a protective effect against heart disease.

Brien and colleagues argue that their study strengthens the case that there is a causal link between alcohol consumption and reduced heart disease.

The authors of both papers acknowledge that a number of previous studies have concluded that moderate alcohol consumption has been associated with a decrease in heart disease. However, they say that the research was out-of-date and there was a need for new material. Professor Ghali says his team’s research is the most comprehensive to date.

Ghali and colleagues reviewed 84 studies of alcohol consumption and heart disease. They compared alcohol drinkers with non-drinkers and their outcomes in relation to heart disease, death from heart disease, incidences of stroke and death from having a stroke.

In the companion study, Brien and colleagues reviewed 63 studies and investigated alcohol consumption with known physical markers for heart disease such as cholesterol, levels of inflammation, fat cells and the condition of blood vessels. They also assessed the impact of the type of alcohol consumed (wine, beer and spirits).

Interestingly, Brien’s research concludes that it is the alcohol content that provides the health benefits not the type of alcoholic beverage (wine, beer or spirits) that is drunk.

Professor Ghali concludes that the debate between the impact of alcohol on heart disease should now centre “on how to integrate this evidence into clinical practice and public health messages”.

He adds “with respect to public health messages there may now be an impetus to better communicate to the public that alcohol, in moderation, may have overall health benefits that outweigh the risks in selected subsets of patients A… any such strategy would need to be accompanied by rigorous study and oversight of impacts”.

15 Quick, Easy Ways to Boost Your Metabolism for Lazy Dummies


3. Drink More Water

The body needs water to process calories. If you are even mildly dehydrated, your metabolism may slow down. In one study, adults who drank eight or more glasses of water a day burned more calories than those who drank four. To stay hydrated, drink a glass of water or other unsweetened beverage before every meal and snack. In addition, try munching on fresh fruits and vegetables, which are full of fluid, rather than pretzels or chips.

4. Have Your Drinks on the Rocks

Ice-cold beverages prompt the body to burn more calories during digestion. Research suggests five or six glasses of water on the rocks can use up an extra 10 calories a day. That might not sound like much, but it adds up to a pound of weight loss per year -- without dieting. You can get the same benefit by drinking iced tea or coffee, as long as you forego the cream and sugar.

5. Drink Green Tea

Drinking green tea or oolong tea offers the combined benefits of caffeine and catechins, substances shown to rev up the metabolism for a couple hours. Research suggests drinking two to four cups of either tea may push the body to burn an extra 50 calories each day. That adds up to 5 pounds of weight loss in a year.

6. Drink Black Coffee

If you’re a coffee drinker, you probably enjoy the increased energy and concentration that follows your morning ritual. Well, some of these benefits are linked to a short-term increase in your metabolic rate. In one study, the caffeine in two cups of coffee prompted a 145-pound woman to burn 50 extra calories over the next four hours. Just be sure to drink it black. If you add cream, sugar, or flavored syrups, you’ll take in far more calories than you burn.

7. Eat More Often

Eating more really can help you lose weight -- eating more often, that is. When you eat large meals with many hours in between, you train your metabolism to slow down. Having a small meal or snack every 3 to 4 hours keeps your metabolism cranking, so you burn more calories over the course of a day. Several studies have also shown that people who snack regularly eat less at meal time.

8. Eat More Protein

The body burns up to twice as many calories digesting protein as it uses for fat or carbohydrates. Although you want to eat a balanced diet, replacing some carbs with lean, protein-rich foods can jump-start the metabolism at mealtime. Healthy sources of protein include lean beef and pork, fish, white meat chicken, tofu, nuts, beans, eggs, and low-fat dairy products.

9. Eat Metabolism Boosting Foods

There are lots of metabolism boosting foods that will even help you loose weight. For example, according to a Penn State University study, soup is a super appetite suppressant because it’s made up of a hunger-satisfying combination of liquids and solids. In the study, women chose one of three 270-calorie snacks before lunch. Women who had chicken and rice soup as a snack consumed an average of 100 fewer calories than those in the study who opted for a chicken and rice casserole or the casserole and a glass of water.

Grapefruit is another great metabolism boosting food. Researchers at Scripps Clinic found that participants who ate half a grapefruit with each meal in a 12-week period lost an average of 3.6 pounds. The study indicates that the unique chemical properties in this vitamin C-packed citrus fruit reduce insulin levels, which promotes weight loss and boost metabolism.

Milk, low-fat yogurt, broccoli, apples and pears are some more metabolism boosting foods, but there are more. Make sure you stay tuned to Health-be (better yet, subscribe to Health-be) for my upcoming article,
Metabolism Boosting Foods.

10. Vitamin B12

Vitamin B12 is flying off health-food-store shelves, with women swearing that megadoses help boost their metabolism; but experts say no research bolsters anecdotal claims. "The B vitamins are essential, but they won't speed up your metabolism," says professor of nutrition Jeff Hampl.

11. Eat Hot & Spicy

Spicy foods contain chemical compounds that kick the metabolism into high gear. Eating a tablespoon of chopped red or green chili pepper can temporarily boost your metabolic rate by 23 percent. Some studies suggest the effect only lasts about half an hour, but if you eat spicy foods often, the benefits may add up. For a quick boost, spice up pasta dishes, chili, and stews with red-pepper flakes.


12. Reduce Stress

Control what you can, but don't worry about what you can't. Keep stress levels in check by managing your time, focusing on the present and not over-committing.

13. Get Enough Sleep 

Make sure yoi get 7-8 hours of Z's a night. For your engine to fire properely during the day, it needs to regenerate at night.

This is really the last of the simple ways to boost your Metabolism for lazy dummies, because hereafter it gets to be a little more work. 

14. Kick Up Your Workout

This is where the simple ways to boost your metabolism stop being quite so simple, but even more, stop being for for lazy dummies. This is where it starts getting tough. Where you need to start putting in some effort. But that's why I listed it close to bottom of the list.

However, if you're doing all of the above, you've already come a long way. Maybe you've even revved up your metabolism to the point by now, that you have enough energy to want to work out!

Aerobic exercise may not build big muscles, but it can rev up your metabolism in the hours after a workout. The key is to push yourself. High-intensity exercise delivers a bigger, longer increase in resting metabolic rate than low- or moderate workouts. To get the benefits, try a more intense class at the gym or include short bursts of jogging during your regular walk.

15. Build Muscle

Our bodies constantly burn calories, even when we’re doing nothing. This resting metabolic rate is much higher in people with more muscle. Every pound of muscle uses about 6 calories a day just to sustain itself, while each pound of fat burns only 2 calories daily. That small difference can add up over time. In addition, after a bout of resistance training, muscles are activated all over your body, increasing your average daily metabolic rate.

Caution

Crash diets involve eating fewer than 1,000 calories a day. This is dangerous for anyone hoping to quicken their metabolism. Although these diets may help you drop pounds, often the high percentage of the loss comes from muscle. The lower your muscle mass, the slower your metabolism. The final result is that you burn fewer calories and gain weight faster than before the crash diet.

Conclusion

The impact of different foods and drinks on the metabolism is small compared to what you need for sustained weight loss. Your best bet for creating a mean calorie-burning machine is to build muscle and stay active. The more you move during the day, the more calories you burn. And remember: working out in the morning has the benefit of revving up your metabolism for hours.

Though it will not affect your daytime activity, research has shown that your metabolism does slow down significantly once you fall asleep, so anything you eat before going to bed will contribute to weight gain.

The 14 Health Wonders of Water

Do You Drink Enough Water?    

Water makes up 60% of your body weight, and everything inside depends on water to run smoothly. 

When you don’t get enough water and dehydrate, it strains your body ways you probably never even thought about. 

I will be discussing the downfalls of not drinking enough water, the benefits of drinking enough water, and how much water you should drink bellow. So read on and learn how to live better, happier and longer.  

1. Stay Slimmer With Water

Trying to lose weight? Water revs up metabolism and helps you feel full.Replace calorie-laden beverages with water, and drink a glass before meals to help you feel fuller.

Drinking more water also helps amp up metabolism - especially if your glass is icy cold. Your body must work to warm the water up, burning a few extra calories in the process.

2. Lower Stress With Water

85% of your brain tissue is water. If you’re dehydrated, both your body and your mind will be stressed.

If you’re feeling thirsty, you’re already a little dehydrated.

To keep stress levels down, keep a glass of water at your desk or tote a sports bottle and sip regularly.

3. Water Boosts Your Energy

If you’re feeling drained and depleted, get a pick-me-up with water. Dehydration makes you feel fatigued.

Water helps the blood transport oxygen and other essential nutrients to your cells.

If you’re getting enough water, your heart also doesn’t have to work as hard to pump blood throughout your body. To avoid acidity and fatigue drink cold water.

4. Keeps up your concentration

Your body needs water to help flush out poisons from things like junk food and additives.If you are dehydrated, toxins hang around in the liver, making you tired and unable to concentrate. Water swills the poisons out and gets the system moving again.

5. Reduces Infections


The lymphatic system is your waste disposal system, breaking down toxins like caffeine before passing them into the blood stream. Dehydration weakens the flow of lymph in the system and makes the body less resistant to infection.With Water, lymph flows properly again, fighting infection and lowering feverish temperatures.

7. Stay Regular With Water

Without Water the contents of the colon (lower intestine) can dry out and get stuck, eventually causing diverticulitis. Constipation can also be a problem, because water is needed to bulk out feces.

Along with fiber, water is essential to good digestion. Drinking water, along with taking in water from Fruit and Vegetables, helps to rehydrate this waste.

Water helps dissolve waste particles and passes them smoothly through your digestive tract.

If you’re dehydrated, your body absorbs all the water, leaving your colon dry and making it more difficult to pass waste.

8. Build Muscle Tone With Water


Drinking water helps prevent muscle cramping and lubricates joints in the body.

When you’re well hydrated, you can exercise longer and stronger without "hitting the wall."

9. Banishes Bags


Sunken eyes and under eye circles are signs that you need water. Eyes sink because there isn’t enough water to keep them suspended in the eye socket. Under-eye circles are due to thin skin being bruised as fluid drains away.

10. Stops Cramps


Blood transports oxygen to the muscles for activities such as exercise. If there isn’t enough oxygen in the blood, the muscles create lactic acid which causes painful cramp. Drinking more water helps to keep blood pumped with oxygen.



11. Reduces Cystitis

A healthy hydrated body removes waste with light yellow virtually odourless urine. If you are not drinking enough, the darker urine is more highly concentrated and waste products linger in the bladder, leaving you prone to cystitis and kidney infections.

12. Prevents Fluid Retention


When you are felling puffy as women often do before a period, drinking water isn’t your immediate thought.

But it’s the best treatment for reducing fluid retention.

If your body doesn’t get enough water, it senses there is a shortage and begins to retain every drop it needs for vital daily processes.

13. Keeps your breath Sweet

Bad breath is a classic sign that you need to boost your water intake. Saliva helps cleanse the teeth of bacteria and keeps the tongue hydrated.

Lack of water dries the mouth, leads to furry tongue and prevents bacteria from being washed away, all of which can cause halitosis.

14. Water Reduces Kidney Stones

The rate of painful kidney stones is rising because people - including children - aren't drinking enough water.

Water dilutes the salts and minerals in your urine that form the solid crystals known as kidney stones.

Kidney stones can't form in diluted urine, so reduce your risk with plenty of water!

Things to Consider when Drinking Water

Water in diet is called a life-saver. It is more important than food. Everybody knows about water. It plays important role in our life.

Bellow are a few things to consider when drinking water:

  • One should drink a glass of water at a time, otherwise trouble of indigestion occurs.
  • Do not drink water before or after meals
  • On should not take water, before and after meal as it creates indigestion. Since it dilutes digestive fluid, due to this constipation and indigestion develop.
  • One should not take water immediately after urination and taking sun bath.
  • We should take water early morning before going to toilet, patient should be given boiled water to drink.
  • Whenever you feel thirsty, immediately drink water. Don’t drink water in standing position because it harms to knee, so always drink water in sitting position.
  • Don’t take water while you are empty stomach, take jiggery then drink water.
  • Don’t go running or jogging after drinking water.
  • Should not drink water when you lay down.

How much Water should You Drink?

Generally, nutritionists recommend we follow the "8x8 rule." In other words, drink eight 8-ounce glasses of water a day. You may need more water if you exercise or sweat heavily. You may need less water if you drink other beverages often.

Although bottled water companies would like for you to believe that their water is the way to go, most bottled water has undesirable, even harmful properties to it. Though it may not contain the fluoride and harmful metals and other contaminants of your faucet, there is a better, healthier way to hydrate.

Boil your water, letting it cool by placing it in the refrigerator. Sometimes it is even better to boil it, drinking it warm to avoid cold, stomach related problems, breathing related problems and hiccups.

How much water do you drink? Do you find it hard to drink the recomended amount of water? Like always, my Health-be readers and I would like to know, so please leave your opinion in the form of a comment bellow. We appreciate it!
