Is Coffee our Friend or Foe?


There is a plethora of information out there regarding the consumption of coffee. Is it healthy or unhealthy to drink coffee? How much is too much? Unfortunately, this is a complicated subject, and a lot of information provided by scientist tends to contradict. And one of the main reasons for this occurrence is due to coffee being composed of many chemicals.

The most common chemical present in coffee, which Sergio Cortes says is also responsible for causing addiction, is caffeine. Many plants, such as cocoa leaves and tea leaves, produce caffeine as an insecticide. This chemical keeps predators away from them. But although caffeine is not lethal to humans, it does provide one with several effects, stimulation which countless people crave.

Our bodies produce a chemical called adenosine, and this chemical, if present in large amounts, is what makes us sleepy.  However, caffeine also stimulates our nervous system and adrenaline, which can cause us negative effects in high amounts. Common negative effects are high levels of anxiety and abnormal levels of blood pressure, which can be worst to certain individuals.

But scientist have found out the there are other chemicals that are as influential as caffeine. There are a group of chemicals known as polyphenols, and these are also produce by many fruits and vegetables as insecticides as well.  And studies show that people that consume conventional amounts of coffee a day have a daily intake of polyphenols of at least one gram.

In order to obtain a good balance, researchers recommend that people stick to lighter roasts, which is where polyphenols tend to be more prominent. They also recommend to people to not drink more than two cups of coffee within an hour in order to not overdose in caffeine. Thus, the answer to this question is still not objective, and drinking coffee is still healthy.

The Zika Virus Could Spread In The City Of Xerém According to Dr. Sergio Cortes

Dr. Sergio Cortes is the Brazilian government’s Secretary of Health. On a recent visit to the flooded city of Xerém, Cortes was looking for signs of infectious diseases. Xerém sits about 30 miles north of Rio de Janeiro. The topography is mountainous so the city is rather isolated from it neighboring cities. The Capivari River became a home wrecker when it spilled out into the city after one of Brazil’s notorious spring rains. More than 8 inches of rain flooded the streets, and turned them into a huge garbage dump. The river did the rest of the damage. More than 250 people lost their homes and one person lost their life.

A Brazilian medical team, under the direction of Dr. Cortes of crunchbase, visited the water-logged city a day after the event. City officials provided a homeless camp for the victims of the flood, and the medical team brought antibiotics and calamity kits. The team also used sodium hypochlorite to remove the free radicals that accumulated in the drinking water. Cortes asked for bottled water donations, as well as food donations. The medical team immediately started to look for symptoms of leptospirosis and other mosquito related diseases.

There were no reported cases of the Zika virus before the flood, according to Dr. Sergio Cortes. An article posted by explained the conditions in Xerém and what the Cortes mission was while he and his medical team were there. The main mission was to stop the spread of mosquito-related diseases, and to remove any potential mosquito breeding grounds. That mission was a bigger task than the team realized once they started to assess the areas around the city where mosquitoes could breed.

The Brazilian government decided not to waste time talking about the spread of the Zika virus in Xerém. Xerém is located in an area where the virus could spread quickly. Dr. Cortes and the medical team believe the army will come in and begin to treat the area in order to destroy the mosquito population. The team’s job was to identify symptoms and eliminate risks. According to the article, the medical team has set up the appropriate procedures to prevent an outbreak of any mosquito related diseases.

Dr. Cortes has extensive medical training and all his credentials are listed on his LinkedIn page. Cortes also has a Twitter account and he is very active on that social network.
