Apple Cider Vinegar and Health

By Joy Manning

Apple Cider Vinegar and Weight Loss


Have you heard that apple cider vinegar will help you lose weight? 
The only study to test the idea in people was done in Japan. In the study, 175obese but healthy people took either vinegar or water daily for 12 weeks. Theirdiets were similar. They kept food journals. At the end of the study, those who used vinegar had lost slightly more weight. On average, the vinegar group lost 1-2 pounds over the 3-month period. They gained it all back after the study was over.
The researchers suggest that vinegar may turn on certain genes involved in breaking down fats.
The effect is probably very subtle, says Chicago dietitian Debbie Davis, RD. “It may have some benefits in terms of weight loss and weight management, but it is definitely not a quick fix." 
If you want to lose weight, you’ll still need to exercise and practice portion control.

Apple Cider Vinegar and Blood Sugar

While apple cider vinegar probably won’t make you skinny, it does appear to help with diabetes and blood sugar control.
Carol Johnston, PhD, directs Arizona State University’s nutrition program. She has been studying apple cider vinegar for more than 10 years and believes its effects on blood sugar are similar to certain medications.
“Apple cider vinegar’s anti-glycemic effect is very well documented,” Johnston says.
She explains that the vinegar blocks some of the digestion of starch. “It doesn’t block the starch 100%, but it definitely prevents at least some of that starch from being digested and raising your blood sugar,” Johnston says.
Not every expert feels as confident about apple cider vinegar’s power.
"Trying to use vinegar to treat diabetes is like trying to bail out a flooded basement with a teaspoon," says Michael Dansinger, MD, director of Tufts University’s diabetes lifestyle coaching program.
He advises patients to focus instead on their overall diets -- a strategy backed by a lot more research, he says.
If you have gastroparesis, a common problem with diabetes that slows stomachemptying, be careful. Early research shows apple cider vinegar may make this problem worse.
"I’m concerned that drinking vinegar, even diluted in water, increases acid in your system, which puts a strain on your kidneys and bones,” Dansinger says.
If you have diabetes and want to try apple cider vinegar, let your doctor know, and keep an eye on your blood sugar levels.
Johnston stresses that if you are on medication for diabetes, you shouldn’t stop taking it and substitute vinegar. If you're thinking about using it to help manage your blood sugar, talk to your doctor first.

11 Tips to Cut Your Cholesterol Fast

Got high cholesterol? Learn what you can do to lower it quickly -- starting today.
By David Freeman

How's your cholesterol? If you think that the normal reading you got back in 2004 (or earlier) means you're in the clear, think again: Levels of the artery-clogging substance often rise with age, and cardiologists say everyone 20 or older should be screened for high cholesterol at least once every five years, with more frequent screenings for anyone deemed to be at high risk for heart disease. If it's been awhile since your last cholesterol screening, now's a good time to ask your doctor if you're due for one.
The good news? If your fasting total cholesterol level exceeds the desirable level of 200, or if your low-density lipoprotein (LDL, or "bad”) cholesterol is not at your goal, getting it down to a safer level could be easier than you think. In fact, with simple lifestyle modifications -- and, if necessary, medicine -- people often see significant reductions in cholesterol within six weeks. 
Here are 11 tips from WebMD health experts on how to cut high cholesterol fast:

1. Set a target.

You know you've got to get your cholesterol number down, but how low do you need to go? That depends on several factors, including your personal and family history of heart disease, as well as whether you have cardiovascular risk factors, such as obesity, high blood pressure, diabetes, and smoking.
If your risk is deemed high, "most doctors will treat for a target LDL of less than 70," says James Beckerman, MD, a cardiologist in private practice in Portland, Oregon. If your risk is moderate, a target LDL of under 130 is generally OK, Beckerman says. If your risk is low, less than 160 is a reasonable target. "The trend now is to treat people earlier, especially if they have two or more risk factors," he says.

2. Consider medication.

Lifestyle modifications make sense for anyone with elevated cholesterol. But if your cardiovascular risk is high, you may also need to take a cholesterol-lowering drug. Michael Richman, MD, medical director of the Center for Cholesterol Management in Los Angeles, calls drug therapy "the only thing that will work fast" to lower high cholesterol. "Everyone should do the basics, like stopping smoking and losing weight," Richman tells WebMD. "But these things lower the risk only modestly. They're nothing to write home about."
Beckerman agrees. "Lifestyle modifications are important, but we should also be emphasizing the benefits of medication when appropriate," he says.
Several types of cholesterol-lowering medication are available, including niacin, bile acid resins, and fibrates. But statins are the treatment of choice for most individuals. "Statins can lower LDL cholesterol by 20% to 50%" says Pamela Peeke, MD, assistant professor of medicine at the University of Maryland School of Medicine in Baltimore.

3. Get moving.

In addition to lowering LDL "bad" cholesterol, regular physical activity can raise HDL "good" cholesterol by up to 10%. The benefits come even with moderate exercise, such as brisk walking.
Robert Harrington, MD, professor of medicine at Duke University School of Medicine in Durham, N.C., urges his patients to go for a 45-minute walk after supper.
Peeke tells WebMD, "I ask people to get a pedometer and aim for 10,000 steps a day. If you work at a desk, get up and walk around for five minutes every hour."
Whatever form your exercise takes, the key is to do it with regularity. "Some experts recommend seven days a week, although I think five days is more realistic," Richman says.

4. Avoid saturated fat.

Doctors used to think that the key to lowering high cholesterol was to cut back on eggs and other cholesterol-rich foods. But now it's clear that dietary cholesterol isn't the main culprit. "Eggs don't do all that much [to raise cholesterol]," Beckerman says. "You don't want to be throwing down six eggs a day, but recent data suggest that it's really saturated fat" that causes increases in cholesterol. And if you cooked your eggs in a slab of butter, don't overlook the fat in the butter.                                            
"One of the first things to do when you're trying to lower your cholesterol level is to take saturated fat down a few notches," says Elaine Magee, MPH, RD, the author of several nutrition books, including the forthcoming Tell Me What to Eat If I Have Heart Disease. "The second thing to do is to start eating more 'smart' fats," Magee says. She recommends substituting canola oil or olive oil for vegetable oil, butter, stick margarine, lard, or shortening while cutting back on meat and eating more fish.

5. Eat more fiber.

Fruits and vegetables, including whole grains, are good sources not only of heart-healthy antioxidants but also cholesterol-lowering dietary fiber. Soluble fiber, in particular, can help lower cholesterol. Beckerman says it "acts like a sponge to absorb cholesterol" in the digestive tract. Good sources of soluble fiber include dried beans, oats, and barley, as well as fiber products containing psyllium.

6. Go fish.

Fish and fish oil are chockablock with cholesterol-lowering omega-3 fatty acids. "Fish oil supplements can have a profound effect on cholesterol and triglycerides," Beckerman says. "There's a lot of scientific evidence to support their use." Fish oil is considered to be quite safe, but check with your doctor first if you are taking an anti-clotting medication.
Magee recommends eating fish two or three times a week. "Salmon is great, as it has lots of omega-3s," she says. But even canned tuna has omega-3s, and it's more consumer-friendly. The American Heart Association also recommends fish as the preferable source of omega-3s, but fish oil capsule supplements can be considered after consultation with your physician. Plant sources of omega-3s include soybeans, canola, flaxseeds, walnuts, and their oils, but they don't provide the same omega-3s as fish. The  biggest heart benefits have been linked to omega-3s found in fish.

7. Drink up.

Moderate consumption of alcohol can raise levels of HDL "good" cholesterol by as much as 10%. Doctors say up to one drink a day makes sense for women, up to two a day for men. But given the risks of excessive drinking, the American Heart Association cautions against increasing your alcohol intake or starting to drink if you don't already.

8. Drink green.

Magee suggests green tea as a healthier alternative to sodas and sugary beverages. Indeed, research in both animals and humans has shown that green tea contains compounds that can help lower LDL cholesterol. In a small study conducted in Brazil, people who took capsules containing a green tea extract were able to reduce their total cholesterol.

9. Eat nuts.

Extensive research has demonstrated that regular consumption of nuts can bring modest reductions in cholesterol. Walnuts and almonds seem particularly beneficial. But nuts are high in calories, so limit yourself to a handful a day, experts say.

10. Switch spreads.

Recent years have seen the introduction of margarine-like spreads and other foods fortified with cholesterol-lowering plant compounds known as stanols.

11. Don't smoke.

Smoking lowers levels of HDL "good" cholesterol and is a major risk factor for heart disease.

Why it's a winner: Interval training boosts your fitness levels and burns more calories to help you lose weight. The basic idea is to vary the intensity within your workout, instead of going at a steady pace.
How to: Whether you walk, run, dance, or do another cardio exercise, push up the pace for a minute or two. Then back off for 2 to 4 minutes. Exactly how long your interval should last depends on the length of your workout and how much recovery time you need. A trainer can fine-tune the pacing.. Repeat the intervals throughout your workout.

3.Squats
