Why eating sugar is even bad for healthy peoples (Many fatal heart problems)?


Why eating Sugar is bad?

This new study suggests why eating too much sugar is bad for everyone.  Sometimes we think we are not eating any sugar directly but there many hidden sources in our daily life foods.


Could too much sugar be deadly? The biggest study of its kind suggests the answer is yes, at least when it comes to fatal heart problems. It doesn't take all that much extra sugar, hidden in many processed foods, to substantially raise the risk, the researchers found, and most Americans eat more than the safest amount. Having a cinnamon roll with your morning coffee, a super-sized sugary soda at lunch and a scoop of ice cream

after dinner would put you in the highest risk category in the study. That means your chance of dying prematurely from heart problems is nearly three times greater than for people who eat only foods with little added sugar.
For someone who normally eats 2,000 calories daily, even consuming two 12-ounce cans of soda substantially increases the risk. For most American adults, sodas and other sugary drinks are the main source of added sugar. Lead author Quanhe Yang of the U.S. Centers of Disease Control and Prevention called the results sobering and said it's the first nationally representative study to examine the issue.

less sugar more fruit

Scientists aren't certain exactly how sugar may contribute to deadly heart problems, but it has been shown to increase blood pressure and levels of unhealthy cholesterol and triglycerides; and also may increase signs of inflammation linked with heart disease, said Rachel Johnson, head of the American Heart Association's nutrition committee and a University of Vermont nutrition professor. Yang and colleagues analyzed national health surveys between 1988 and 2010 that included questions about people's diets. The authors used national death data to calculate risks of dying during 15 years of follow-up.
Overall, more than 30,000 American adults aged 44 on average were involved. Previous studies have linked diets high in sugar with increased risks for non-fatal heart problems, and with obesity, which can also lead to heart trouble. But in the new study, obesity didn't explain the link between sugary diets and death. That link was found even in normal-weight people who ate lots of added sugar. "Too much sugar does not just make us fat; it can also make us sick," said Laura Schmidt, a health policy specialist at the University of California, San Francisco. She wrote an editorial accompanying the study in Monday's JAMA Internal Medicine. The researchers focused on sugar added to processed foods or drinks, or sprinkled in coffee or cereal. Even foods that don't taste sweet have added sugar, including many brands of packaged bread, tomato sauce and salad dressing. Naturally occurring sugar, in fruit and some other foods, wasn't counted.

Most health experts agree that too much sugar isn't healthy, but there is no universal consensus on how much is too much. U.S government dietary guidelines issued in 2010 say "empty" calories including those from added sugars should account for no more than 15 percent of total daily calories. The average number of daily calories from added sugar among U.S. adults was about 15 percent toward the end of the study, slightly lower than in previous years.
The authors divided participants into five categories based on sugar intake, from less than 10 percent of daily calories - the safest amount - to more than 25 percent. Most adults exceed the safest level; and for 1 in 10 adults, added sugar accounts for at least 25 percent of daily calories, the researchers said. The researchers had death data on almost 12,000 adults, including 831 who died from heart disease during the 15-year follow-up. They took into account other factors known to contribute to heart problems, including smoking, inactivity and excess weight, and still found risks for sugar.
As sugar intake increased, risks climbed steeply. Adults who got at least 25 percent of their calories from added sugar were almost three times more likely to die of heart problems than those who consumed the least - less than 10 percent. For those who got more than 15 percent - or the equivalent of about two cans of sugary soda out of 2,000 calories daily - the risk was almost 20 percent higher than the safest level.
Sugar calories quickly add up: One teaspoon has about 16 calories; one 12-ounce can of non-diet soda contains has about 9 teaspoons of sugar or about 140 calories; many cinnamon rolls have about 13 teaspoons of sugar; one scoop of chocolate ice cream has about 5 teaspoons of sugar. Dr. Jonathan Purnell, a professor at Oregon Health & Science University's Knight Cardiovascular Institute, said while the research doesn't prove "sugar can cause you to die of a heart attack", it adds to a growing body of circumstantial evidence suggesting that limiting sugar intake can lead to healthier, longer lives.

Why girls sexy online profile image has more Negative consequences than Positive?


Why Sexy online profile photos not a good idea?

I think this study shows lot of truth…
If you want to know why Young women with sexy social media photos seen as less competent, you will know after reading this new study.
Girls and young women who post sexy or revealing photos on social media sites such as Facebook are viewed by their female peers as less physically and socially attractive and less competent to perform tasks, a new study from Oregon State University indicates.

Why girls sexy online profile image has more Negative consequences than Positive?

“This is a clear indictment of sexy social media photos,” said researcher Elizabeth Daniels, an assistant professor of psychology who studies the effect of media on girls’ body image. Daniels’ findings are based on an experiment she conducted using a fictitious Facebook profile.“There is so much pressure on teen girls and young women to portray themselves as sexy, but sharing those sexy photos online may have more negative consequences than positive,” Daniels said.
Girls and young women are in a “no-win” situation when it comes to their Facebook photos, Daniels said. Those who post sexy photos may risk negative reactions from their peers, but those who post more wholesome photos may lose out on social rewards, including attention from boys and men, she said. “Social media is where the youth are,” she said. “We need to understand what they’re doing online and how that affects their self-concept and their self-esteem.”

Why girls sexy online profile image has more Negative consequences than Positive?
Daniels’ research was published today in the journal Psychology of Popular Media Culture. The article, titled “The price of sexy: Viewers’ perceptions of a sexualized versus non-sexualized Facebook profile photo,” was co-authored by Eileen L. Zurbriggen of the University of California, Santa Cruz. Daniels conducted the research while on the faculty at OSU-Cascades and received two Circle of Excellence grants from OSU-Cascades to support the study. She is now an assistant professor of psychology at the University of Colorado in Colorado Springs. For the study, Daniels created two mock Facebook profiles for the fictitious 20-year-old Amanda Johnson. In both versions, Amanda liked musicians such as Lady Gaga, books such as “Twilight,” and movies like “The Notebook,” that would be appropriate for a person her age.

The only difference between the two was the profile photo. The photos were actual high school senior portrait and prom photos of a real young woman who allowed the photos to be used for the experiment. In the sexy photo, “Amanda” is wearing a low-cut red dress with a slit up one leg to mid-thigh and a visible garter belt. In the non-sexy photo, she’s wearing jeans, a short-sleeved shirt and a scarf draped around her neck, covering her chest.

Why girls sexy online profile image has more Negative consequences than Positive?
Study participants were 58 teen girls, ages 13-18, and 60 young adult women no longer in high school, ages 17-25. They were randomly assigned one of the profiles and asked questions based on that profile. The participants were asked to assess Amanda’s physical attractiveness (I think she is pretty), social attractiveness (I think she could be a friend of mine), and task competence (I have confidence in her ability to get a job done) on a scale from 1-7, with one being strongly disagree and 7 being strongly agree. In all three areas, the non-sexy profile scored higher, indicating that those who viewed that photo thought Amanda was prettier, more likely to make a good friend and more likely to complete a task. The largest difference was in the area of task competence, suggesting a young woman’s capabilities are really dinged by the sexy photo, Daniels said.
The research underscores the importance of helping children and young people understand the long-term consequences of their online posts, Daniels said. Parents, educators and other influential adults should have regular conversations about the implications of online behavior with teens and young adults, Daniels suggested. “We really need to help youth understand this is a very public forum,” she said. The research also highlights the need for more discussion about gender roles and attitudes, particularly regarding girls and young women, she said. “Why is it we focus so heavily on girls’ appearances?” she said. “What does this tell us about gender? Those conversations should be part of everyday life. “Daniels’ advice for girls and young women is to select social media photos that showcase their identity rather than her appearance, such as one from a trip or one that highlights participation in a sport or hobby. “Don’t focus so heavily on appearance,” Daniels said. “Focus on who you are as a person and what you do in the world

Scientific reasons- Why drinking coffee before exercise is great IDEA

This is good news for the people who love coffee.
The Spanish study, published in the International Journal of Sport Nutrition and Exercise Metabolism, found that trained athletes who took in caffeine pre-exercise burned about 15% more calories for three hours post-exercise, compared to those who ingested a placebo.
How many bucks for your brew? The dose that triggered the effect was 4.5 mg of caffeine per kilogram of body weight. For 150-pound woman, that's roughly 300 mg of caffeine, the amount in about 12 ounces of brewed coffee, a quantity you may already be sipping each morning. If you've always thought of coffee as a vice -- one you're simply not willing to give up -- you'll be happy to know that it's actually a secret superfood. And if you exercise, caffeine can offer even more functional benefits for your workouts.

Scientific reasons- Why drinking coffee before exercise is great IDEA
Here are many reasons to enjoy it as part of an active lifestyle, along with some "rules" for getting your fix healthfully.

Muscle preservation
In an animal study, sports scientists at Coventry University found that caffeine helped offset the loss of muscle strength that occurs with aging. The protective effects were seen in both the diaphragm, the primary muscle used for breathing, as well as skeletal muscle. The results indicate that in moderation, caffeine may help preserve overall fitness and reduce the risk of age-related injuries.

Improved circulation
Recent Japanese research studied the effects of coffee on circulation in people who were not regular coffee drinkers. Each participant drank a 5-ounce cup of either regular or decaffeinated coffee. Afterward, scientists gauged finger blood flow, a measure of how well the body's smaller blood vessels work.
Those who downed "regular" (caffeinated) coffee experienced a 30% increase in blood flow over a 75-minute period, compared to those who drank the "unleaded" (decaf) version. Better circulation, better workout -- your muscles need oxygen!
 Scientific reasons- Why drinking coffee before exercise is great IDEA
Less pain

Scientists at the University of Illinois found that consuming the caffeine equivalent of two to three cups of coffee one hour before a 30-minute bout of high-intensity exercise reduced perceived muscle pain. The conclusion: caffeine may help you push just a little bit harder during strength-training workouts, resulting in better improvements in muscle strength and/or endurance.

Better memory

A study published this year from Johns Hopkins University found that caffeine enhances memory up to 24 hours after it's consumed. Researchers gave people who did not regularly consume caffeine either a placebo or 200 mg of caffeine five minutes after studying a series of images. The next day, both groups were asked to remember the images, and the caffeinated group scored significantly better.
This brain boost may be a real boon during workouts, especially when they entail needing to recall specific exercises or routines.

More muscle fuel
A recent study published in the Journal of Applied Physiology found that a little caffeine post-exercise may also be beneficial, particularly for endurance athletes who perform day after day.
The research found that compared to consuming carbohydrates alone, a caffeine/carb combo resulted in a 66% increase in muscle glycogen four hours after intense, glycogen-depleting exercise. Glycogen, the form of carbohydrate that gets stockpiled in muscle, serves as a vital energy "piggy bank" during exercise, to power strength moves, and fuel endurance.

Some basic rules to best reap caffeine's rewards

Don't overdo it.
The maximum amount of caffeine recommended for enhancing performance with minimal side effects is up to 6 mg per kg body weight, which is about 400 mg per day (or about 16 ounces of coffee) for a 150-pound woman.

Incorporate it in healthy ways
Doctor up coffee with almond milk and cinnamon instead of cream and sugar, or whip coffee or tea into a fruit smoothie, along with other nutrient-rich ingredients like almond butter and oats or quinoa.

Be consistent with your intake
 Research shows that when your caffeine intake is steady, your body adjusts, which counters dehydration, even though caffeine is a natural diuretic. In other words, don't reach for two cups one day and four the next.

Keep drinking good old water, your main beverage of choice

Try a new Modest test to Check Your Heart Health


Simple test for checking your heart health

With this new test we all can now easily how our heart is doing. Has your doctor ever checked your blood pressure in both arms? If not, you’re missing out on a valuable test of heart health. That’s the conclusion of Harvard instructor Ido Weinberg, MD, whose recent research shows that a more than 10-point difference in systolic blood pressure between arms can be a red flag for heart attack, stroke, and cardiovascular disease.

Try a new Modest test to Check Your Heart Health

You’d expect that it wouldn’t matter which arm the nurse puts the cuff on – blood pressure is blood pressure, right? Not so fast. According to Weinberg’s study, published in the March issue of the American Journal of Medicine, about 10 percent of adults over 40 had interarm differences of more than 10 points – and this point spread was associated with an almost 40 percent increase in risk of heart attack, stroke, or other cardiovascular event.
While experts knew that very large differences in arm-to-arm blood pressure readings could suggest cardiovascular disease, this is the first research to link a relatively small difference of just 10 points with significantly increased risk. As part of Harvard/Massachusetts General Hospital’s Framingham Heart Study, the researchers followed 3390 healthy people age 40 and older (with no prior sign of heart disease), over a period of 13 years and found a 38% risk increase in those with a 10-point or greater arm-to-arm difference. (The average arm-to-arm or interarm difference, the researchers say, is less than 5 points.)

Try a new Modest test to Check Your Heart Health

A previous study published in The Lancet in 2012 found that a 15-point arm-to-arm difference in systolic blood pressure doubled the risk of peripheral artery disease, or clogging of the arteries further away from the heart. Why is having a difference in blood pressure one one side of the body so significant? Because it suggests blockage or slowing of blood flow, most likely from artery-clogging plaque. The other potential cause, an aortic dissection or tear in the aorta, is even more serious. Concludes Weinberg: “This study supports the potential value of identifying the interarm systolic blood pressure difference as a simple clinical indicator of increased cardiovascular risk.”
Systolic blood pressure (the top number when your doctor tells you your BP is “X over X”) measures the pressure in your arteries as your blood flows through while your heart is beating. Diastolic, the second or lower number, measures blood pressure while the heart is resting between beats. You want your blood pressure under 120/80; above that is considered prehypertension and anything above 140/90 indicates hypertension and the need for intervention. According to the American Heart Association, systolic blood pressure is considered more important than diastolic as a measure of cardiovascular health because it shows how strongly and clearly your blood if flowing. If you’re like me, reading this study will make you want to run out and check your own arm-to-arm blood pressure ratio. If you have a home blood pressure monitor -  a useful health tool for anyone whose BP is even slightly elevated – you can check both arms yourself right now. If not, you can get your blood pressure checked anytime at your local drug store, or ask the medical staff to repeat your blood pressure screening in both arms next time you see your doctor. Since 2005, the American Heart Association’s blood pressure screening guidelines have recommended taking blood pressure readings in both arms as a baseline reading. But I don’t know about you – I’ve never experienced that happening. So I’m certainly going to ask.
