SUPPORT YOUR HEART



“If you exercise regularly, eat right and don’t smoke, you are on your way to healthier heart”, says Dr. Willet.

Taking a few healthy lifestyle steps can help you feel better and reduce your risk of heart attack and stroke. Here, what you need to know to eat right, get active and quit smoking.

To put the pieces of an ideal heart-healthy eating plan together, “think of diet and nutrition like an orchestra- all components should be balanced for optimal heart health”, says Walter Willett, MD chair of the nutrition department at the Harvard School of Public Health.

EAT FOR YOUR HEART:

To get started, try these six simple steps:

Ø Control your portion size

Fill half a normal dinner plate with green leafy, bright or deeply colored vegetables such as spinach and beets. These veggies are packed with heart-healthy nutrients. Leave a quarter each for lean protein and complex carbohydrates, such as potatoes (no fried), brown rice and whole wheat pasta.

Ø Eat less red meat

It’s high in saturated fat, which boosts cholesterol levels. Instead, choose proteins such as broiled or grilled fish, skinless poultry and beans. Consider eating one meat-free meal a day.

Ø Choose nonfat and low-fat dairy

Opt for skim or soy milk, fat-free yogurt and low fat cheese. Dairy is rich in potassium, which reduce stroke risk, according to recent research.

Ø Fill up on fruits and vegetables

The American Heart Association (AHA) recommends you get at least four to five cups of fruit and the same amount of vegetable daily. One cup is about of woman’s fist.

Ø Favor fiber-filled foods

Fiber-rich foods such as produce and whole grains are satiating- so you may feel fuller longer. Soluble fiber, found in beans, peas, oats, apples, citrus, barley and psyllium, can help lower cholesterol.

Ø Toss the salt shaker

Salt causes fluid retention, which raises blood pressure and can worsen angina. Follow the AHA recommendation of less than 1500 mg a day, unless your doctor suggest otherwise. To reduce salt in your diet, eat more fresh food and fewer processed products, which tend to be loaded with sodium. If you’re out at a restaurant, ask if the chef can prepare low salt versions of menu items for you.

 

          GET MOVING:

          Exercise will help make you stronger and increase what’s known as exercise tolerance, how much you can physically exert yourself before becoming exhausted. The better your exercise tolerance becomes, the harder you can work out without experiencing angina pain. Exercise also helps lower blood pressure, cholesterol and blood glucose levels.

Ø Enlist a buddy

Plan to exercise with your spouse, a family member or friends to help you stay committed.

Ø Start slow and build up

“You don’t have to work out like an Olympic athlete”, says Robert Eckel, MD, head of preventive cardiology at the University of Colorado Anschutz Medical Campus in Aurora.

How much exercise is enough to help your heart?

Thirty minutes a day, at least five days a week, of brisk walking is fairly standard. However, if you heart’s sake, your doctor may want you to strive for an hour of physical activity daily. You can break it up into 15 minute chunks.

Ø Log it

Keep track of the time, speed and duration of you walks.

 

          KICK BUTTS

          Quitting is essential for anyone who smokes, but it’s especially important for people with angina.

Smoking causes your arteries to constrict, which can make angina worse. Talk to your doctor about tools for quitting. Research shows that combining support and medical therapy is most effective.

FISH OIL MAY PROTECT AGAINST ALCOHOL-RELATED DEMENTIA

Exposure to a compound found in fish oil may protect against the development of dementia in heavy drinkers, new research suggests.
A study presented at the recent Congress of the European Society for Biomedical Research on Alcohol in Warsaw, Poland, examined rat brain cells exposed to alcohol levels equivalent to 4 times the legal driving limit.
Results showed that the cell cultures that were also exposed to omega-3 docosahexanenoic acid (DHA) showed approximately 90% less neuroinflammation and 90% less neuronal brain cell death compared with the cells that were not exposed to the fish oil compound.
"We hypothesized that omega-3 fatty acids, specifically DHA (which has been shown to neuroprotect from other acquired brain insults in the laboratory and to some degree in human studies) would suppress or prevent the neuronal degeneration due to binge alcohol exposure," principal investigator Michael A. Collins, PhD, professor in the Department of Molecular Pharmacology and Therapeutics at the Stritch School of Medicine at Loyola University, Chicago, Illinois, told Medscape Medical News.
"And basically, that is what we found," he added.
Relevant to Humans
Dr. Collins noted that although this was an animal study designed to measure neurodegeneration and related phenomena, and not a study specifically of dementia, "since brain degeneration underlies persistent or permanent dementia, the results were extrapolated to what might happen in humans."
And although he noted in a release that further studies are now needed, "fish oil has the potential of helping preserve brain integrity in abusers. At the very least, it wouldn't hurt them."
In 2011, Dr. Collins and colleagues published a meta-analysis of 143 studies showing that consuming up to 2 alcoholic drinks a day for men and 1 drink a day for women appeared to reduce the risk for dementia and cognitive impairment.
However, "too much alcohol overwhelms the cells," they noted in a release.
"Our previous work and that of others had linked neurodegeneration to 'neuroinflammatory'-like mechanisms that include oxidative stress (oxygen and nitrogen free radicals). The oxidative stress, we suspected, resulted in part from alcohol-induced excessive release of unsaturated fatty acids from brain membranes," explained Dr. Collins.
In the current study, the researchers exposed brain cell cultures from adult rats to heavy amounts of alcohol and then compared half the cells, which were further exposed to omega-3 DHA, with the other nonexposed half.
"Our results indicate excessive arachidonic acid (AA) mobilization due to increased phospholipase A2 (PLA2) levels/activity, and this appears related to elevations in astroglial aquaporin-4 (AQP4) and brain edema," write the investigators.
In other words, excessive drinking can cause higher levels of PLA2 activity, leading to excessive production of AA (a polyunsaturated omega-6 fatty acid), which in turn leads to increased AQP4/neuroinflammation and swelling of the brain.
However, inhibiting AQP4 was found to be neuroprotective to the cells.

Adding omega-3 DHA to the cell cultures not only significantly decreased the release of AA and the elevated levels of PLA2 and AQP4 but also decreased ADP-ribose polymerase-1 (PARP1) elevations and overall neurodamage.
Dr. Collins reported that the investigators are planning now to conduct studies that replicate the findings in intact adult rats exposed to binge-drinking levels of alcohol and that elucidate how DHA exerts its protection in the brain.
However, he stressed that helping heavy drinkers to cut back the amounts they consume or to quit altogether is the best way to protect their brains.
"We don't want people to think it's okay to take a few fish oil capsules and then continue to go on abusing alcohol," he said.
The study was supported by the Loyola University Alcohol Research Program and a grant from the United States Public Health Service.
