Green coffee is bitter, but study says it takes off the weight

Scientists today reported striking new evidence that green, or unroasted, coffee beans can produce a substantial decrease in body weight in a relatively short period of time.

In a study presented at the 243rd National Meeting & Exposition of the American Chemical Society, Joe Vinson and colleagues described how a group of overweight or obese people who consumed a fraction of an ounce of ground green coffee beans each day lost about 10 percent of their body weight.

“Based on our results, taking multiple capsules of green coffee extract a day — while eating a low-fat, healthful diet and exercising regularly — appears to be a safe, effective, inexpensive way to lose weight,” Vinson said at the society meeting being held in San Diego, California. He is with the University of Scranton in Pennsylvania.

The study involved 16 overweight or obese people aged 22 to 26 years who took capsules of the extract or capsules containing a placebo, an inactive powder, for a total of 22 weeks. The subjects alternated between a low dose and a higher dose of the extract. The low dose consisted of 700 miligrams of the coffee extract, and the high dose was 1,050 miligrams. It was a so-called cross-over study in which people cycled through the two doses and the placebo, each for six weeks. Such studies have advantages because each person serves as his or her own control, improving the chances of getting an accurate result, researchers said.

All of the participants were monitored for their overall diet and exercise over the study period. “Their calories, carbohydrates, fats and protein intake did not change during the study, nor did their exercise regimen change,” Vinson said.

Participants lost an average of 17 pounds during the 22 weeks of the study. It included an average of a 10.5 percent decrease in overall body weight and a 16 percent decrease in body fat. Vinson noted that weight loss might have been significantly faster, except that participants received the placebo and the lower dose of green coffee extract for part of the study period.

Vinson pointed out that previous studies have shown weight loss with green coffee. But this was the first to use higher amounts of the coffee extract and the first to measure the response to various doses. Based on those studies, Vinson believes that green coffee beans’ effects likely are due to a substance called chlorogenic acid that is present in unroasted coffee beans. Chlorogenic acid breaks down when coffee beans are roasted, usually at a temperature of 464 to 482 degrees F. Roasting gives coffee beans their distinctive color, aroma and flavor. Green coffee beans, in contrast, have little aroma and a slightly bitter taste.

45 percent of Ticos think they can get HIV from a mosquito bite, says University of Costa Rica report

Over 75 percent of young Costa Ricans surveyed do not know how HIV is transmitted or contracted, according to a new study from the University of Costa Rica released Wednesday.

The report’s results suggest that Costa Rica is in need of a serious overhaul of its sexual education policy. Many respondents said that the human immunodeficiency virus was passed through mosquito bites or through kissing someone who is HIV-positive. More than 84 percent surveyed said they don’t use condoms.

The report, which used information from a 2010 national health survey and received support from the President’s Emergency Plan for AIDS Relief, PEPFAR, analyzed responses from over 3,000 men and women in Costa Rica aged 18-80.

Here’s what Ticos got right:

  • 91.8 percent correctly responded that risk of HIV infection was reduced by limiting sexual activity to one HIV-negative partner.
  • 93.7 percent said that using a prophylactic every time they have intercourse would reduce their chance of contracting HIV.

What Ticos got wrong:

  • 55.5 percent did not know how to correctly use a condom.
  • 45 percent incorrectly answered that a mosquito bite could transmit HIV.
  • 48.6 percent said that an HIV-positive person would always show signs of infection.
  • 40.2 percent said that the virus could move between people through sweat or saliva.

Only 18.2 percent of Ticos aged 15-17 demonstrated comprehensive understanding of the disease. Knowledge of HIV-AIDS increased after age 18, but remained below 26 percent for respondents aged 18-35.

Awareness and knowledge about HIV-AIDS improved with years of education and if the respondent lived in an urban area.

One of the problems highlighted in the report is where young people get information about HIV-AIDS and sex in general: their peers. Barely 18 percent of young Ticos had a good grasp of sexually transmitted diseases. This same group was the largest source of information about the subject for respondents under 18 years old.

Parents, apparently, are not having the birds and the bees talk with their kids, according to the report.

Mothers (62.3 percent) and fathers (46.2 percent) were the most desired sources of information about sex, but respondents’ friends (28.8 percent) were the most commonsource of information about sex. Only 24 percent said their mother was a source for this information, and just over 10 percent named their father.

The report also pointed out that there was a correlation between men and women who are the victim of verbal or physical sexual abuse and “risky” sexual behavior. The UCR report defined risky sexual behavior as infrequently using a condom and having more than one sexual partner in the last 12 months.

Adrián Barrientos, a sociologist involved in the study, told The Tico Times that more needs to be done to change how Costa Ricans think about condoms. Barrientos said that Ticos are more likely to use a condom when they want to avoid having more children than to protect against STDs. Unwanted children are a more effective motivator to use a prophylactic than STDs.

Presenters noted that men who have sex with men, male to female transgender people, and intravenous drug users are among the groups with the highest risk of contracting HIV-AIDS. Researchers said that they hope the report’s results can help target these groups and better educate the wider public about safe sex and STDs.

Some 1.4 million people had HIV-AIDS in Latin America in 2011, according to the report. One hundred and thirty eight Costa Ricans died of HIV-AIDS in 2010, according to the Health Ministry.
