CDC has given no explanation for its new guidelines that say testing for coronavirus needs to be done only for those with symptoms, not for those exposed to someone within 6 feet who has symptoms. About half of all new cases are from people who are exposed to people with symptoms but have not yet developed symptoms. One of the reasons the virus spread quickly in February is CDC failure in developing of its own test on February 9 and policy that did not let private labs and labs of teaching hospitals develop their own tests and use them for another 3 crucial weeks.  CDC and Health and Human Services Department errors in February, combined with the stalling of an American team for 3 weeks by China to enter Wuhan in January,  have combined to let the coronavirus spread to the wider population. Once it spreads to a wider population the strategy of test and trace cannot be implemented the way it was first in South Korea and Taiwan, and later in Germany. ...

A federal committee in the U.S. now recommends no more than 6% of calories come from daily sugar intake not the 10% that is is the current guideline. It is smart to be wary of guidelines set in a different period when Americans and people in other parts of the world were not enough health conscious as they should have been. Artificially high limits set in guidelines serve as a danger to health, particularly as experts say obesity is like pouring gasoline on fire in fighting the coronavirus. Take a look at mean consumption today and it is not even the 10%, it is 13% double of what it should be. Nearly two thirds of Americans aged 1 years or older consumed more than 10% of daily calories in added sugar. And 70% of U.S. adults over 20 years are obese or overweight according to 2015-2016 figures from CDC. Today the figures from Europe and Asia, Latin America are also alarmingly high for obesity rates. Added sugar comes from processed foods from soda and pasta sauce to cereal and yogurt, and honey, sugar itself. Sugar sweetened beverages are common and dangerous. A 16 ounce grande pumpkin spice latte at Starbucks has 50 grams of sugar or 10% of a 2000 calories diet. The committee in the U.S. wants to see people eat healthy diets and does not want to discourage healthy foods like fruit and milk which people are not eating enough. It wants to see a shift away from processed foods to foods that have good health outcomes such as fruits, vegetables, whole grains, and lean meat and poultry. The beverage producers such as Coca Cola and Pepsi are a major source of resistance , as are Confectioners association, and other producers that benefit from setting the guidelines at 10%. It is not that for 3 decades as the obesity levels rose to the shocking and dismal health levels of today that the ideas of what constitutes a healthy diet were not known. It was just that we as a people did not care enough to fight for what is safe and healthy against whatever resistance was put up by producers with their vested interests, just as we as a people did not care enough to to fight to keep local manufacturing in place and the jobs and healthy communities across our land. A gram of sugar equals 4 calories. For a 2000 calories a day diet that is 120 calories to stay within the 6% that we should not exceed. Make a habit of looking at each packaged product and add up the added sugar grams and calories. ...

The failure to set clear and consistent guidelines by the U.S. Centres for Disease Control that the public can easily grasp and follow without retractions or errors has affected how the public responded in the pandemic. Here the CDC is shown to have first put forward a draft version on the role of aerosol and respiratory droplets in the air for spreading coronavirus infections and then pulled it back followed by putting it back on last week.

Much of it is about being definitive and 100% certain instead of focussing on the steps that are clearly going to reduce the spread of the pandemic and appealing to the good common sense of the public about following reasonable precautions of social distancing, masks, ventilation, staying away from gatherings.

The Federal Trade Commission says food companies in the U.S. spent $2.3 billion in 2006 for advertising to children. With the epidemic in childhood obesity in the U.S., this raises serious questions about how product packaging, images and themes affect the eating behaviour of children. New guidelines have now been written at the request of Congress. They were written by the F.T.C., the Food and Drug Administration, the Agriculture Department, and the Centers for Disease Control. The regulatory agencies say they will take comments and consider changes before submitting a report to Congress. The guidelines call for foods advertised to children to include healthy ingredients such as whole grains, fresh fruits and vegetables, or low fat milk. The foods cannot contain unhealthy amounts of sugar, saturated fat, trans fat and salt. The sugar requirement would have cereals contain no more than 8 grams of added sugar per serving. Fruit Loops for example contains 12 grams of sugar per serving. The guidelines apply to both children and teenagers. However these guidelines are voluntary. At this time an industry led effort has not produced results. The Children's Food and Beverage Advertising Initiative, which is operated by the industry, lets each company set its own nutritional criteria. The regulatory agencies see the need for the food industry to follow a uniform set of standards. Without serious action on this issue the U.S. healthcare system will continue to be burdened with high rates of obesity related illnesses in the general population, and out of control costs. And the U.S. will continue to face the urgent problem of a lack of healthy eating habits of children teenagers, and adults....

In a Senate hearing Dr. Fauci, head National Institute of Infectious Diseases, Dr. Redfield, head of CDC, and Dr. Hahn, head of the FDA, answered questions from U.S. Senators including committee chairman Lamar Alexander and Senator Murray. Dr. Fauci told senators that with some states reopening without meeting federal guidelines that include seeing an extended period of falling numbers of cases and deaths, "there is a real risk you could trigger an outbreak ... that could set you back rather than going forward."  Dr Fauci is concerned about the situation in the fall when schools and colleges reopen with possible spread. In other comments Robert Redfield the CDC head told the committee- "timely testing is vital to reopen America, increased contact tracing is critical." Redfield says CDC has created a state by state assessment of contact tracing and was working with states on these surveillance systems. This contact tracing effort is one of the less developed areas in which the focus is being shifted to along with testing capabilities. Admiral Giror who heads testing capability buildup says 40 to 50 million tests should be available by September 2020, so that hotspots could be addressed quickly. ...

The German government has taken notice of hate speech on social media and social bots. The Justice Ministry convened a task force on hate speech on internet. Justice Minister Heiko Maas promised legal action against social media like facebook and twitter if it violated laws of libel and inciting to violence. Chancellor Merkel is bringing in a data science expert Professor Simon Hegelich of the Technical University of Berlin for consultations in Dec. 2016. Only AfD of the main parties, with its anti-immigration stance, has not come out in favor of not using social bots or paid trolls in the 2017 elections. Hegelich in talk with DW.com says it is hard to legislate on this because the whole phenomenon has not been fully understood. Article 5 of the Constitution provides for free speech. Hegelich also says the state of technology moves faster than legislation, and being international sites like facebook, twitter and others pose additional issues. He does not say laws cannot be helpful but that its not clear how best to do this. Thomas Jarzombek is a CDU member of parliament and digital media expert. He says social bots are more likely controlled by foreign countries, and fake news sites are more of a domestic problem. Making this worse is the incentive for unemployed journalists to do blogging of the crude and aggressive type to make more money. Jarzombek sees the need for the press to do more in its role for the democratic process to function properly, by functioning in the role of "enlightenment" and "awareness."  Jenna Behrends, a law student and CDU local politician for Berlin-Mitte, says it is necessary for good bots to be used to fight bad bots, in an article in Der Spiegel. Major mainstream media would then have to launch social bots themselves to fulfill their role of providing the public with correct and fair information free of excessive bias and distortion of the bad bots. One example of this is shown explicitly here of German chancellor Merkel's picture with the words " Guilty of betraying the people," with links to "Drain the swamp," and "Brexit." A more complex question is one of how to let people vent out frustration about the mainstream media itself being biased in favor of the established views and not doing enough or giving enough space to reflect alternative views, so that these can be debated without inflammatory language and deliberate distortion. A whole range of tools and modifications of behaviour may be necessary ahead of next years elections in France and Germany, now that the phenomenon is better understood following a vote in the Anglo-Saxon countries.   ...

Only 23% of meals in America include a vegetable. The number of dinners made at home with a salad dropped to 17% in 2010 compared to 22% in 1994. Salads ordered at restaurants dropped to 5% in 2010 from 10% in 1989, according to NPD research company in its 25th edition of "Eating Patterns in America." The U.S. is going backwards in good eating habits and no enough attention is being paid to this in the debate about cost of health care. Their is a clear connection between good eating habits and health, and while invention and use of the latest research and innovations in health care are lauded, the decline in patterns of healthy living and food habits are receiving less attention.

Chile, Mexico and the U.S. rank high in the diabetes rate for top soda consuming countries. In the U.S. the diabetes rate is at 7.7% of the population, in Chile 9.6% and Mexico 9%. Soda consumption per capita was at 165 litres in the U.S., 146 litres in Mexico and 134 litres in Chile, and 145 litres in Argentina where the diabetes rate is at 3.9%, for 2012. A new public service ad in Mexico City subway stations says it all, showing an ad with a soda bottle and the words- "Would you take 12 teaspoonfuls of sugar? Soda is sweet, diabetes isn't." The new Pacto de Mexico agreed to by all major political parties includes the soaring diabetes rate in Mexico as a problem to be tackled, including lunches at public schools and the consumption of coke and sodas by children. A particular acute problem in Mexico is the lack of clean drinking water in many areas and the dependence on coke and sodas for liquids. But bottled water could be used in its place if available at lower prices. One proposal is for a soda tax which could generate $2 billion and be used for setting up clean drinking water fountains in schools and other places. Elected officals in Mexico are firm about the need for action, as Mexico recently became the first country over 100 million inhabitants with the highest obesity rates at 7 adults out of 10 over the age of 20 obese or overweight, and the consequently high diabetes rate. Diabetes is the No. 2 killer in Mexico, and a serious health danger. Coca Cola gets its second highest revenues from Mexico after Europe, and the situation has evolved after years of heavy coke advertising to the point where Coca Cola is taken at every meal by some Mexican families, and is a sign of prestige. The company's response is to fight the public service ads with ads showing people burning off 149 calories by walking. The country now faces a long and uphill fight. Russia is one of the countries which is also conducting a similiar fight against soda drinks. The Bloomberg Philanthropy is financing efforts against soda drinks in Mexico, as part of its campaign against smoking and sodas as health hazards, and this maybe Bloomberg's bigger contribution to society than his service to New York City. Developing middle income countries such as Mexico, Chile, India, China, Brazil, are the hardest hit by soaring diabetes. And the costs to their health systems in 10-20 years from uncontrolled obesity and diabetes will be enormous. The U.S. is a developed country with similiar high rates of obesity and diabetes, with soaring medical costs, and serious problems that strangely have not received the public awareness and efforts that one should expect. ...
