Every Bit of Junk Food, Fast Food Damages Your Arteries, Paves Way for Coronary Artery Disease

Think just one burger won’t do any damage? Not so, according to a University of Montreal study, which shows that even one meal high in saturated fat damages arteries.

Dr. Anil Nigam, Director of Research at the Cardiovascular Prevention and Rehabiliation Centre (EPIC) of the university-affiliated Montreal Heart Institute co-authored the study comparing the health of vascular endothelium (inner lining of blood vessels) in response to a meal of junk food versus a typical Mediterranean meal.

The study involved 28 non-smokers who ate a Mediterranean-influenced meal (salmon, almonds, and vegetables cooked in olive oil) in one week and fast food (sausage, egg, and cheese sandwich with three hashbrowns) in the next. In both meals, calories were derived between 50 and 60 percent from fat, but the Mediterranean fats were monounsaturated and polunsaturated, whereas the fast food meal’s fats were saturated with no omega 3 fatty acids. Before eating and two and four hours after each meal, the participants were evaluated for baseline endothelial funciton.

The results were about what one might expect. After eating junk food, the subjects’ arteries dilated 24 percent less than when measured in a fasting state, constricting blood flow. Arteries after subjects had eaten a healthy Mediterranean meal, however, functioned normally.

Every Meal is a Health Choice

“Poor endothelial function is one of the most significant precursors of atherosclerosis,” Dr. Nigam says. The degree of dilation of arteries is very closely associated with their hardening, known as atherosclerosis, and coronary artery disease.

“It is now something to think about at every meal.”

Subjects with higher blood triglycerides also saw benefits from the Mediterranean meal, and “individuals with high triglyceride levels, such as patients with metabolic syndrom, [would benefit] precisely because it could help keep arteries healthy,” Dr. Nigam add.

In addition to the findings revealing the damage to arteries, junk food and fast food have also been shown to cause depression. In fact, the study, published in the journal Public Health Nutrition, shows that those consuming fast food are 51 percent more likely to be depressed than those consuming very little or none of the health-damaging food. What’s more, depression risk was found to increase with the more fast food and junk food consumed.

Fresh Versus Fast Food

Monounsaturated fats—like those found in olive oil—are one of the top 5 brain foods that boost cognition, and polyunsaturated fatty acids help build new brain cells. Omega 3 fatty acids have numerous benefits, too, not least of all helping to pave way for longevity and improved mood.

We make hundreds of decisions about food daily; it’s important that we make them well. Although fresh food may not always be the more affordable decision (and it often is), it’ll pay you back in the long run when you have cheaper medical bills!

This is the world’s first commercial flying car

The world’s first commercial flying car is already on sale. It is equipped with two retractable propellers and rear wings.

The vehicle was presented during the Miami Art Week 2019 by the Dutch company PAL-V International. It is called Liberty, and its price is around 600,000 dollars.

It has Dutch engineering and Italian design, it is already in active production and has at least 70 anticipated.

“As soon as Nicolas Cugnot invented the car and the Wright brothers made their first successful flight, people began to dream of combining the two in a flying car.”

‘It turned out to be more complicated than initially estimated: a complex puzzle. However, once resolved, it would create maximum freedom in mobility’, said the executive director of the company, Robert Dingemanse.

When will it be available?

The first units are expected to reach their owners in 2021. However, it must be borne in mind that to handle it, it is necessary to have not only the driver’s license, but also the pilot’s license.

The new car has two versions, the Pioneer and the sports version. Robert Dingemanse explained that the Pioneer version differs from Liberty by its a complete carbon package. He also revealed that only 90 flying cars will be manufactured in this version.

Features of the flying car

The PAL-V, a three-wheeled vehicle that can carry up to two passengers and 20 kilos of cargo, is basically a hybrid between a car and a helicopter.

According to the company website, the PAL-V has a four-cylinder engine and is capable of flying at an altitude of up to 3,500 meters. The vehicle, which is made with carbon fiber, titanium and aluminum and weighs only 664 kilograms, uses gasoline for cars and can reach maximum speeds of 180 km / h in the air and 160 km / h on land.

It also has both a ground and air system similar to that of a motorcycle in which the pilot-driver tilts the machine with a control lever.

It also stands out that the PAL-V converts from car to gyrocopter in just 10 minutes and can accelerate from 0 to 100 km / h in less than 9 seconds.

A patient in England has been diagnosed with a rare case of monkeypox, as reported by Public Health England (PHE).

The rare viral infection is similar to smallpox, and though it is milder, it can be fatal.

It has been reported that the individual was in Nigeria and that he would have contracted the disease there. Later, upon returning to the United Kingdom, he stayed in the southwest of England where the disease occurred.

Upon symptoms, he was transferred to the Guy’s and St Thomas’ NHS Foundation Trust , a center specializing in infectious diseases in London.

The health authorities have taken the necessary measures to prevent the virus from spreading to other people.

The PHE said in a statement:

As a precaution, PHE experts are working closely with NHS colleagues to implement rapid infection control procedures, including contact with people who may have been in close contact with the individual to provide health information and advice. ”

But experts are not very worried about contagion, because monkeypox does not spread easily among people and the risk of affecting the population is quite low, said Dr. Meera Chand , PHE consulting microbiologist.

Although the infection usually occurs mildly and people get better without treatment; Some individuals may develop very serious symptoms, with a percentage of 1 to 10 percent of patients dying from the disease during outbreaks, according to the World Health Organization .

The symptoms presented are similar to those of smallpox but milder. First, fever, headaches, muscle aches, back pain, swollen lymph nodes, chills and exhaustion. Subsequently rashes may appear on the skin , starting on the face and spreading throughout the rest of the body.

This is not the first time a patient has been infected with smallpox in the United Kingdom. In 2018, there were three cases after a person was diagnosed with the disease. The individual had also returned from Nigeria.

A cold virus can infect a pregnant woman’s fetus

The study showed that the expectant mother is able to transmit a respiratory tract infection to her unborn child.

Scientists from Tulane University (Louisiana, USA) received the first evidence that the cold virus, which affects a pregnant woman, can penetrate the placenta and infect the fetus. An article about this has been published in PLOS One .

The placenta, an organ that develops in the uterine cavity of a woman during pregnancy, provides the necessary nutrition from the mother to the embryo and simultaneously performs another important task: it filters out potential pathogenic microorganisms. However, a group of pediatricians led by Professor Giovanni Piedimonte found that this natural “barrier” is not so impenetrable.

Scientists took the placenta from donors, isolated three main types of cells – cytotrophoblasts, fibroblasts and Kashchenko – Hofbauer cells – and in vitro exposed them to the human respiratory syncytial virus, which causes respiratory tract infections. Although cytotrophoblast cells supported a weak process of the spread of the virus, two other types were more susceptible to infection. So, Kashchenko-Hofbauer cells survived and allowed the virus to replicate inside the cell walls. According to scientists, then these cells, moving inside the placenta, are able to transmit the virus to the fetus.

“Such cells do not die after they become infected,” Piedimonte explains. – When they enter the fetus, they are comparable to bombs stuffed with a virus. They do not spread the virus in the area of ​​the “explosion”, but carry it through the intercellular channels. <…> Thus, our theory is confirmed that when a woman gets a cold during pregnancy, the virus that causes the infection can pass to the fetus and cause a pulmonary infection before the birth of a child. ”

Pediatricians also suggested that the respiratory syncytial virus is able to infect the lung tissue of the unborn baby and provoke the development of an infection that will subsequently affect the predisposition to asthma. To confirm or refute their theory, the authors of the study intend to conduct clinical tests.

Last year, scientists from the University of Cambridge created an artificial and functional mini-placenta using trophoblasts, and recently it turned out that particles of air pollution can penetrate the placenta of pregnant women
