Artificial Sweetener Use Among Kids Rose 200% in Less than 15 Years

Artificial sweetener use increased 200% among children and 54% among children from 1999 to 2012. Health experts are especially concerned about the spike in use among kids because the scientific community still doesn’t know the full health repercussions of long-term, low-cal sweetener use. [1]


According to the study published in the Journal of the Academy of Nutrition and Dietetics, in 1999, only 8.7% of children reported consuming artificial sweeteners, but that number had jumped to 25.1% by 2012.


Lead study author Dr. Allison Sylvetsky, assistant professor of exercise and nutrition sciences at the George Washington University Milken Institute School of Public Health, said:




“The findings are important, especially for children, because some studies suggest a link between low-calorie sweeteners and obesity, diabetes and other health issues.” [1]



Learning the Bitter Truth About Fake Sweeteners


For the study, researchers looked at data on some 17,000 adult men, women, and children that came from the National Health and Nutrition Evaluation Survey (NHANES) from 2009-2012, and compared their analysis to a previous study that used data from 1999-2008. Of the data, researchers specifically reviewed results from the 2 dietary interviews in which people reported what they ate or drank during the 24-hour period prior.


The team found that 25.1% of children and 41.4% of adults reported consuming low-calorie sweeteners. The majority of low-cal sweetener users reported using them once daily (80% of children and 52% of adults), and how often participants consumed the sweeteners increased with body weight in adults. Seventeen percent of adults in the study consumed artificial sweeteners 3 or more times a day.


Furthermore, the study showed that children as young as 2 had consumed artificial sweeteners in foods and beverages, representing 1 in 4 children involved.


Why the Increase?



The study authors point to obesity-prevention campaigns aimed at reducing sugar intake, increased availability of artificial sweeteners, increasingly inexpensive products, and/or increased prevalence of Type 2 diabetes as the reason for the sharp increase in low-calorie sweetener use. [2]


Sylvetsky said:



“While we anticipated an increase, the magnitude of the increase was much larger than we had anticipated, particularly in kids.
It is not surprising that low-calorie sweetener consumption continues to increase, though. … There has been a lot of pressure put on the food and beverage industry to reformulate, which has led to more lower-sugar, low-calorie sweetener containing products appearing on the market.” [3]



Rachel Hicks, a spokeswoman for the American Beverage Association, said in a statement:



“Decades of scientific research, as well as regulatory agencies around the globe, have repeatedly reaffirmed the safety of low- and no-calorie sweeteners as part of the diet. And the science is clear that because they have few, if any, calories these sweeteners can be an effective tool for weight loss or as part of a weight management plan.”




Do Artificial Sweeteners Provide Any Benefit?


However, another study published in PLOS Medicine suggests there is a lack of evidence to support the role of artificial sweeteners in preventing weight gain.


Sylvetsky said that it’s not clear “how low-calorie sweeteners may influence appetite, weight management, and risk of chronic diseases such as diabetes,” though the products are believed to be safe in toxicology.


Are they really safe, though?


In recent years, research has emerged showing that some of the most popular low-calorie sweeteners may cause negative health effects. For example, an 11-year study showed that consuming 2 or more diet drinks is associated with a 2-fold increased risk of kidney function decline in women.



A study published in the American Journal of Clinical Nutrition revealed that, despite safety reports of aspartame, the sweetener is still associated with health concerns such as non-Hodgkin lymphoma, multiple myelomas, and leukemia, though the researchers admitted that “cancer risk in individuals who consume regular soda do not permit the ruling out of chance as an explanation.”

Splenda, or sucralose, has become a popular alternative to aspartame and saccharine because it is made from sugar. However, a 2013 study showed that sucralose caused cancerous tumors in mice. The researchers behind that study also acknowledged that sucralose is able to alter gut microbes.


If you absolutely need to sweeten a food or drink, use organic, “raw” sugar.

California Will Get Swamped by Millions of Mosquito-Killing … Mosquitoes

Researchers at the Google-linked science company Verily are in the process of releasing 20 million sterile mosquitoes into the Fresno County, California, area in an attempt to actually stop the disease-carrying menaces from breeding. [1]


The effort is dubbed the “Debug Fresno” project, the goal of which is to greatly reduce the number of invasive Aedes aegypti mosquitoes in the area. The Zika-carrying insects first arrived in California’s Central Valley in 2013. The mosquitoes also have the ability to spread dengue fever and chikungunya viruses. Officials say the bugs adapted rapidly to the area’s residential neighborhoods. [2]

Steve Mulligan, district manager for the region’s Consolidated Mosquito Abatement District (CMAD), explained:




“It’s a terrible nuisance, a terrible biting nuisance. It’s changed the way people can enjoy their backyard and it’s a threat for disease transmission. So we’re looking for new ways to eliminate it.”


The Bloodline Stops There


The tens of millions of mosquitoes are being infected with Wolbachia bacteria and raised inside a laboratory. Wolbachia makes male Aedes aegypti mosquitoes sterile. Then, once the insects have matured, they will be released to mate with credulous female Aedes aegypti mosquitoes.

The altered males don’t bite, but, obviously, you wouldn’t know that as you swat at them at your family barbecue.


If the naive females lay eggs, it won’t matter; they will never hatch.


Ultimately, the scientists’ plan is to eliminate the mosquitoes, generation by generation.

Mulligan said:


“It’s kind of contrary to what a person would think. ‘What, you’re doing what? You’re releasing mosquitoes to control mosquitoes?’ We are releasing male mosquitoes because male mosquitoes do not bite and cannot transmit disease.”


Verily, a subsidiary of Alphabet (formerly Google Life Sciences), estimates they will release 1 million mosquitoes a week in Fresno County. That’s upwards of 25 times the numbers in 2016. This is made possible because scientists have developed ways to breed the mosquitoes, and separate the sexes on a larger scale.


Verily spokeswoman Kathleen Parkes explained:


“Automated sex-sorting is a key advancement for this research. Traditionally, mosquito sex-sorting is a very labor-intensive process. Verily has developed a system that uses computer vision algorithms to identify the sex of the mosquitoes and only let the males through.”


Future field studies will let scientists know whether or not Verily’s plan lowered the number of Aedes aegypti mosquitoes in Fresno County.


If all goes as planned, those 20 million mosquitoes will get released between mid-July and the fall of 2017.


Theoretically, if the program is successful, it could be used to stomp out all mosquito-borne illnesses on Earth. [2]


Linus Upson, a senior engineer at Verily, said:




“If we really want to help people globally, we need to be able to produce a lot of mosquitoes, distribute them to where they need to be, and measure populations at very-very low costs.” [3]


Verily blog wrote:


“To measure our outcomes, we will compare the adult population density and egg hatching of Aedes aegypti in these targeted areas to two control neighborhoods. Over time, we hope to see a steep decline in the presence of Aedes aegypti in these communities.”



The Other Side of the Card


Wow, can you imagine eradicating malaria and yellow fever? It would certainly be a medical and technological breakthrough that redefines life for millions of people around the world who would have died without the technology.


To read about it, it seems quite simple and sure-fire.


But That’s Not Necessarily the Case


A July 2014 study by researchers at Penn State University found that:


“Mosquitoes infected with the bacteria Wolbachia are more likely to become infected with West Nile virus and more likely to transmit the virus to humans, according to a team of researchers.”


The scientists say “that caution should be used when releasing Wolbachia-infected mosquitoes into nature to control vector-borne diseases of humans.”


In a March 2016 letter published in Science magazine, researchers point out that few experiments with Wolbachia-infected mosquitoes have looked at “the probability of Wolbachia strains being transferred to other insects and the potential environmental and economic impacts of this host shift.”


The scientists explain that in a brief evolutionary period, “Wolbachia strains are capable of transferring horizontally among distantly related arthropods.”


Additionally, according to the researchers, parasites are able to carry Wolbachia strains to other species.


The question is: Which is riskier – mosquito-borne disease, or a potential mishap in trying to eradicate the sources of those diseases?

GMO Mosquito Trial Approved in the Florida Keys

On November 19, the Florida Keys Mosquito Control District board voted to approve a trial of genetically modified (GM) mosquitoes designed to fight the Zika virus in the Keys.

The district has been working with British biotech company Oxitec for the last 5 years to get federal approval for a trial release of the genetically engineered male Aedes aegypti mosquitoes into the wild. When they mate with female Aedes aegypti mosquitoes, their offspring die.


The proposed trial had been mired in controversy, as many locals were concerned – and still are – about the many questions that remain unanswered about the altered mosquitoes, such as how being bitten by one of the insects might affect a person. [2]




Oxitec’s tries to release only male mosquitoes, which don’t bite, but it’s estimated that a small number of females do get released. The company claims that even if someone were to be bitten by a female, it wouldn’t matter because the altered genes aren’t in the mosquitoes’ saliva.

There have been more than 200 local cases of the Zika virus throughout Florida, though none of those cases were reported in the Keys. [1]


One of the concerned Keys residents is Megan Hall, who appealed to the district board on Saturday before the vote:


“I am going to ask you, beg you, plead with you not to go forward with this.”


The district voted 3-2 to move forward with the trial anyway.


A Tale of 2 Communities

The residents of 2 Florida Keys communities went to the ballot box on November 8 to vote on a nonbinding ballot measure concerning whether the trial should go on.


Key Haven residents rejected the trial, while nearly 60% of voters in Monroe County voted in favor of releasing the mosquitoes. The insects won’t be released in Key Haven, but the trial will proceed in a location yet to be determined. [1]


Although the Keys hasn’t had a problem with Zika, the area has had problems in the past with dengue, another disease carried by the same mosquito. The head of the county’s health department, Bob Eadie, said he is a proponent of the trial because he sees it as a way of preventing the spread of disease in the future. He explained:


“There is a tool available for the people of Monroe County that can help control mosquitoes that carry a very, very, very serious disease.”


The trial of genetically modified mosquitoes was approved by the U.S. Food and Drug Administration (FDA) in August. The agency said at the time that it had found no potential adverse impact on human health or the environment. The FDA will need to give a final approval once the trial location is determined.




Opponents of the GMO trial say they won’t take the decision lying down. One woman said that if commissioners choose Key Largo as the site for the trial, residents there will hire private mosquito control crews to eradicate the GM mosquitoes. She told the district board:


“Have fun with that.” [2]


Of course, a private company would likely spray chemicals to get rid of the mosquitoes, so that’s not necessarily a better option.
