5 Foods That Can Trigger A Stroke

Few things feel more terrifying and random than a stroke, which can strike without warning. And fear of stroke -- when a blood vessel in or leading to the brain bursts or is blocked by a blood clod, starving brain cells of oxygen and nutrients -- is well founded. After all, stroke is the number-three killer in the U.S., affecting more than 700,000 people each year. Here are five foods that cause the damage that leads to stroke.

01. Crackers, chips, and store-bought pastries and baked goods


Muffins, doughnuts, chips, crackers, and many other baked goods are high in trans fats, which are hydrogenated oils popular with commercial bakeries because they stay solid at room temperature, so the products don't require refrigeration. Also listed on labels as "partially hydrogenated" or hydrogenated oils, trans fats are found in all kinds of snack foods, frozen foods, and baked goods, including salad dressings, microwave popcorn, stuffing mixes, frozen tater tots and French fries, cake mixes, and whipped toppings. They're also what makes margarine stay in a solid cube. The worst offenders are fried fast foods such as onion rings, French fries, and fried chicken
Why it's bad

For years scientists have known trans fats are dangerous artery-blockers, upping the concentrations of lipids and bad cholesterol in the blood and lowering good cholesterol. Now we can add stroke to the list of dangers. This year researchers at the University of North Carolina found that women who ate 7 grams of trans fat each day -- about the amount in two doughnuts or half a serving of French fries -- had 30 percent more strokes (the ischemic type, caused by blocked blood flow to the brain) than women who ate just 1 gram a day. Another recent study, also in women, found that trans fats promoted inflammation and higher levels of C-reactive protein, which have been linked to an increased risk of diabetes, heart disease, and stroke.
What to do

Aim to limit trans fats to no more than 1 or 2 grams a day -- and preferably none. Avoid fast-food French fries and other fried menu items and study packaged food labels closely. Even better, bake your own cookies, cakes, and other snacks. When you can't, search out "health-food" alternative snacks, such as Terra brand potato chips and traditio
nal whole grain crackers such as those made by Finn, Wasa, AkMak, Ryvita, and Lavasch.

02. Smoked and processed meats


Whether your weakness is pastrami, sausage, hot dogs, bacon, or a smoked turkey sandwich, the word from the experts is: Watch out.Why it's badSmoked and processed meats are nasty contributors to stroke risk in two ways: The preserving processes leave them packed with sodium, but even worse are the preservatives used to keep processed meats from going bad. Sodium nitrate and nitrite have been shown by researchers to directly damage blood vessels, causing arteries to harden and narrow. And of course damaged, overly narrow blood vessels are exactly what you don't want if you fear stroke.

Many studies have linked processed meats to coronary artery disease (CAD); one meta-analysis in the journal Circulation calculated a 42-percent increase in coronary heart disease for those who eat one serving of processed meat a day. Stroke is not the only concern for salami fans; cancer journals have reported numerous studies in the past few years showing that consumption of cured and smoked meats is linked with increased risk of diabetes and higher incidences of numerous types of cancer, including leukemia.
What to do

If a smoked turkey or ham sandwich is your lunch of choice, try to vary your diet, switching to tuna, peanut butter, or other choices several days a week. Or cook turkey and chicken yourself and slice it thin for sandwiches.How to Tell if Someone Is Having a Stroke

Although replacing sugary drinks with diet soda seems like a smart solution for keeping weight down -- a heart-healthy goal -- it turns out diet soda is likely a major bad guy when it comes to stroke.
Why it's bad.

People who drink a diet soda a day may up their stroke risk by 48 percent. A Columbia University study presented at the American Stroke Association's 2011 International Stroke Conference followed 2,500 people ages 40 and older and found that daily diet soda drinkers had 60 percent more strokes, heart attacks, and coronary artery disease than those who didn't drink diet soda. Researchers don't know exactly how diet soda ups stroke risk -- and are following up with further studies -- but nutritionists are cautioning anyone concerned about stroke to cut out diet soda pop.
What to do Substitute more water for soda in your daily diet. It's the healthiest thirst-quencher by far, researchers say. If you don't like water, try lemonade, iced tea, or juice.

This winter, when the respected journal Stroke published a study showing that women who consumed a large portion of red meat each day had a 42-percent higher incidence of stroke, it got nutrition experts talking. The information that red meat, with its high saturated fat content, isn't healthy for those looking to prevent heart disease and stroke wasn't exactly news. But the percentage increase (almost 50 percent!) was both startling and solid; the researchers arrived at their finding after following 35,000 Swedish women for ten years.
Why it's bad

Researchers have long known that the saturated fat in red meat raises the risk of stroke and heart disease by gradually clogging arteries with a buildup of protein plaques. Now it turns out that hemoglobin, the ingredient that gives red meat its high iron content, may pose a specific danger when it comes to stroke. Researchers are investigating whether blood becomes thicker and more viscous as a result of the consumption of so-called heme iron, specifically upping the chance of strokes.What to doAim to substitute more poultry -- particularly white meat -- and fish, which are low in heme iron, for red meat. Also, choose the heart-healthiest sources of protein whenever you can, especially beans, legumes, nuts, tofu, and nonfat dairy.

05. Canned soup and prepared foods



Whether it's canned soup, canned spaghetti, or healthy-sounding frozen dinners, prepared foods and mixes rely on sodium to increase flavor and make processed foods taste fresher. Canned soup is cited by nutritionists as the worst offender; one can of canned chicken noodle soup contains more than 1,100 mg of sodium, while many other varieties, from clam chowder to simple tomato, have between 450 and 800 mg per serving. Compare that to the American Heart and Stroke Association's recommendation of less than1,500 mg of sodium daily and you'll see the problem. In fact, a nutritionist-led campaign, the National Salt Reduction Initiative, calls on food companies to reduce the salt content in canned soup and other products by 20 percent in the next two years.
Why it's bad

Salt, or sodium as it's called on food labels, directly affects stroke risk. In one recent study, people who consumed more than 4,000 mg of sodium daily had more than double the risk of stroke compared to those who ate 2,000 mg or less. Yet the Centers for Disease Control estimate that most Americans eat close to 3,500 mg of sodium per day. Studies show that sodium raises blood pressure, the primary causative factor for stroke. And be warned: Sodium wears many tricky disguises, which allow it to hide in all sorts of foods that we don't necessarily think of as salty. Some common, safe-sounding ingredients that really mean salt:

Baking soda
*

Baking powder
*

MSG (monosodium glutamate)
*

Disodium phosphate
*

Sodium alginate

What to do

Make your own homemade soups and entrees, then freeze individual serving-sized portions. Buy low-sodium varieties, but read labels carefully, since not all products marked "low sodium" live up to that promise.

7 More Reasons to Quit Smoking

We all know that cigarette smoking is bad for the health. It arises many risks such as pulmonary diseases, emphysema, heart attacks, stroke, cancer etc. In spite of these complications, many people, particularly those belonging to the younger generations, think of smoking as part of being cool. While some believe that smoking adds appeal to a man’s rogue effect, women who smoke are regarded as sophisticated. Not all can have the same opinion to these, yet one thing is quite agreeable, that smoking can be very bad for the body’s physical features. Smoking can robe a person’s good looks and youth.



Smoking may cause the following:
1.Dry and fragile skin
Smoking reduces the water content of the skin’s outer layer.
2.Wrinkles around the nose and mouth
Chemicals is cigarette such as nicotine, carbon monoxide, tar and lead reduce blood flow to the skin, reducing circulating of oxygen and break down the skin’s collagen and elastin.

3.Risk of Psoriasis
Psoriasis is a disease that causes red scaly patches to appear on the skin. It can be usually seen in the skin of the elbows and knees, but can also affect any area including the scalp and genitals.  Studies reveal that the risk of psoriasis was 37% higher among past smokers and 78% higher among current smokers.


4.Skin cancer
Smokers are more than three times more likely to develop squamous cell carcinoma of the skin than non-smokers. Smoking induces skin cancer by holding back the immune system. And patients with suppressed immune systems are more susceptible to squamous cell carcinoma in many locations, including the skin.

5.Hair loss
Hair is able to grow because of hair follicles. The dermal papilla, which are near the bottom of hair follicles, are responsible for creating new cells. The new cells shove themselves upward, moving the old cells upward. When the cells reach the middle of the hair follicle, they die out and become hard. They become the central core of the hair follicle and afterward, become the new hair shaft. Smoking prevents dermal papilla from growing. This hinders the hair from growing.

6.Yellow teeth
Nicotine and tar leaves a sticky residue on the teeth. Even with one inhalation of cigarette smoke, stains are left behind. There are brands of cigarettes that contain more nicotine and tar than the others. The higher the ratio of nicotine and tar, the more the teeth will be stained by the cigarette.

7.Yellow nails
Tar and nicotine are also the components of cigarette that cause yellow fingernails.  These two stain the fingernails and the skin surrounding the fingers that hold the cigarette.

Twelve ways to keep your brain young


Every brain changes with age, and mental function changes along with it. Mental decline is common, and it’s one of the most feared consequences of aging. But cognitive impairment is not inevitable. Here are 12 ways you can help reduce your risk of age-related memory loss.

1. Get mental stimulation
Through research with mice and humans, doctors suspect that brainy activities stimulate new connections between nerve cells and may even help the brain generate new cells, developing neurological “plasticity” and building up a functional reserve that provides a hedge against future cell loss.

Any mentally stimulating activity should help to build up your brain. Read, take courses, try “mental gymnastics,” such as word puzzles or math problems Experiment with things that require manual dexterity as well as mental effort, such as drawing, painting, and other crafts.

2. Get physical exercise
Research shows that using your muscles may also help your mind. Animals who exercise regularly increase the number of tiny blood vessels that bring oxygen-rich blood to the region of the brain that is responsible for thought. Exercise also spurs the development of new nerve cells and increases the connections between brain cells (synapses). This results in brains that are more efficient, plastic, and adaptive, which translates into better performance in aging animals. Exercise also lowers blood pressure, improves cholesterol levels, fights diabetes, and reduces mental stress, all of which can help your brain as well as your heart.

3. Improve your diet
Good nutrition can help your mind as well as your body. Here are some specifics:
  • Keep your calories in check. In both animals and humans, a reduced caloric intake has been linked to a lower risk of mental decline in old age.
  • Eat the right foods. That means reducing your consumption of saturated fat and cholesterol from animal sources and of trans-fatty acids from partially hydrogenated vegetable oils.
  • Remember your Bs. Three B vitamins, Folic acid, B6, and B12, can help lower your homocysteine levels, high levels of which have been linked to an increased risk of dementia. Fortified cereal, other grains, and leafy green vegetables are good sources of B vitamins.

4. Improve your blood pressure
High blood pressure in midlife increases the risk of cognitive decline in old age. Use lifestyle modification to keep your pressure as low as possible. Stay lean, exercise regularly, limit your alcohol to two drinks a day, reduce stress, and eat right.

5. Improve your blood sugar
Diabetes is an important risk factor for dementia. You can fight diabetes by eating right, exercising regularly, and staying lean. But if your blood sugar stays high, you’ll need medication to achieve good control.





6. Improve your cholesterol
High levels of LDL (“bad”) cholesterol increase the risk of dementia, as do low levels of HDL (“good”) cholesterol. Diet, exercise, weight control, and avoiding tobacco will go a long way toward improving your cholesterol levels. But if you need more help, ask your doctor about medication.

7. Consider low-dose aspirin
Observational studies suggest that long-term use of aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) may reduce the risk of dementia by 10%–55%. It’s hopeful information, but it’s preliminary. Experts are not ready to recommend aspirin specifically for dementia.

8. Avoid tobacco
Avoid tobacco in all its forms.

9. Don’t abuse alcohol
Excessive drinking is a major risk factor for dementia. If you choose to drink, limit yourself to two drinks a day. But if you use alcohol responsibly, you may actually reduce your risk of dementia. At least five studies have linked low-dose alcohol with a reduced risk of dementia in older adults.

10. Care for your emotions
People who are anxious, depressed, sleep-deprived, or exhausted tend to score poorly on cognitive function tests. Poor scores don’t necessarily predict an increased risk of cognitive decline in old age, but good mental health and restful sleep are certainly important goals.

11. Protect your head
You may be surprised to learn that moderate to severe head injuries early in life increase the risk of cognitive impairment in old age. Concussions increase risk by a factor of 10.

12. Build social networks
Strong social ties have been associated with lower blood pressure and longer life expectancies.

What is congestive heart failure ?

Posted by Elizabeth Comeau March 23, 2011 09:59 AM

Hollywood icon and actress Elizabeth Taylor died today in Los Angeles. She was 79 and had congestive heart failure. Just what does that mean?
According to the American Heart Association, congestive heart failure is a condition in which the heart can't pump enough blood to the body's other organs.
The condition can result from a past heart attack, high blood pressure, heart defects present at birth, and coronary artery disease.
Heart failure tends to be more prevalent in older people, affecting 1% of people aged 50, about 5% of those aged 75 or older and 25% of those aged 85 years or older.
Doctors can treat congestive heart failure through rest, diet, and medications, but in some cases a heart can become so damaged over time that a person may need a heart transplant.
