Corona virus outbreak
On December 30th, 2019, China reported an outbreak of a potentially serious respiratory illness related to SARS and MERS in the province of Wuhan. It has since affected over 587,000 people not only in China but also spread to many countries in the world including most countries of Europe, United States, Iran, South Korea, Japan, to name a few, leading to not only significant loss of life, but also unprecedented disruptions in global travel, trade, and complete shut down in many countries around the world.

Is lack of vitamin D making the COVID-19 unstoppable?
WHO coronavirus disease 2019 (COVID-19) situation report (world) | CDC’s US COVID-19 report
- Did you know that the coronavirus needs the same receptors that vitamin D uses and if a person is deficient in vitamin D, the virus can not only gain access to the cells but also replicate uncontrollably leading to a much worse outcomes?
- Did you know that about 42% of the entire population in the United States are deficient in vitamin D, caused in part by the obesity epidemic as the intra-abdominal adiposity that takes up a lot of vitamin D that keeps the population deficient in vitamin D despite supplementation. Learn more

- Up to 71% of Americans are insulin resistant leading to weight gain in the belly and upper part of the body.
- 35 percent of all Americans have metabolic syndrome or prediabetes.
- The estimated annual medical cost of obesity in the United States was $147 billion in 2008 US dollars; the medical cost for people who have obesity was $1,429 higher than those of normal weight.
- More obesity facts from the Center for Disease Control(CDC).
Amazing facts about human body
- The human body contains 30 000 billion red blood cells. The human body is estimated to have 60,000 miles of blood vessels.
- The human heart beats 30 million times a year.
- You have no sense of smell when you're sleeping.
- You burn more calories while sleeping than you do when watching television.

Study:Dietary cholesterol may not raise cardiovascular risk
Although you have long heard that dietary cholesterol is generally not good for the cardiovascular health, you might be surprised to know that high quality, well conducted research studies have shown no relationship between dietary cholesterol and cardiovascular disease. Learn more on the high-quality research finds no link to heart disease.
No limit on dietary cholesterol intake - AHA
For a long time, the American Heart Association has recommended low fat, low cholesterol diet based on assumptions and wrongly interpreted observational studies. Now, the same organization agrees with the above research and says there is no numerical recommendation of cholesterol intake from food, as it finds no link between dietary cholesterol and cardiovascular risk. Learn more on why dietary cholesterol is not the same as blood cholesterol.
Did they mislead the world with wrong recommendations?
The wrong information about fat and cholesterol was spread for so long through the now withdrawn food pyramid, as well as many professional societies leading to significantly increased risk of a new problem called insulin resistance leading to problems such as metabolic syndrome that increase belly fat leading to increased inflammation. It is important to recognize that increased inflammation is the root cause of many human diseases including cardiovascular disease. The failed and now withdrawn food pyramid from the USDA that recommended grains and other high gycemic carbohydrates over fats did not help! Learn more...

Structure of SARS-COv-2, the coronavirus that causes Coronavirus disease 2019.
Like other coronaviruses, SARS-CoV-2 particles are spherical and have proteins called spikes protruding from their surface. These spikes latch onto human cells, then undergo a structural change that allows the viral membrane to fuse with the cell membrane.
The viral genes can then enter the host cell to be copied, producing more viruses. Like the virus that caused the 2002 SARS outbreak, SARS-CoV-2 spikes bind to receptors on the human cell surface called angiotensin-converting enzyme 2 (ACE2).
The SARS-CoV-2 spike was 10 to 20 times more likely to bind ACE2 on human cells than the spike from the SARS virus from 2002.
