Even People with Mild Symptoms of Coronavirus Develop Antibodies

A new study, performed by scientists from France, finds that even people who experienced mild symptoms of the novel coronavirus develop antibodies to it.Even People with Mild Symptoms of Coronavirus Develop Antibodies

For their study, a team of researchers analyzed blood samples taken from 160 medics who had a mild form of COVID-19 and didn’t require hospitalization. The results of the analysis showed that 99.4% of them had antibodies to the virus 13 days after the symptoms.

Olivier Schwartz, one of the leading researchers, comments: “It is a fair assumption that the majority of individuals with mild Covid-19 generate neutralizing antibodies within a month after onset of symptoms. The neutralizing activity is present much later than the appearance of antibodies and this is encouraging.”

9 Foods and Beverages that Can Harm Your Immune System

The best way to support your immune system is to keep a healthy well-balanced diet. Although there are no absolute “good” or “bad” foods for your immunity, healthy eating habits play a crucial role in maintaining the good condition of the immune system. But there are also foods and beverages that can harm the immune system. Here they are:9 foods harmful for your immune system

  1. Alcoholic beverages compromise the immune system by reducing the cells that fight infection. Alcohol drinks increase the susceptibility to pneumonia, sepsis, and poor wound healing.
  2. Caffeine before going to bed hinders your healthy sleep which in turn weakens your immunity.
  3. Canned or dried fruits often contain added sugar leading to an imbalance of the microbiome.
  4. Dairy products may lead to inflammation, a leaky gut, food intolerance in some people.
  5. Junk food provides a high amount of calories, fat, and sodium and low in nutrients like vitamins and minerals.
  6. Food additives, preservatives, and colorings are highly processed and cause inflammation.
  7. Processed foods like bacon, canned soups, and vegetables, frozen dinners contain lots of sugar, refined carbs, additives, and preservatives that are associated with inflammation.
  8. Refined foods like white flour, white bread can cause an imbalance in the gut microbiome.
  9. Refined vegetable oils also can lead to inflammation and imbalance in the gut microbiome.

8 Factors that May Weaken Your Immune System

Even for experts, it is hard to predict how infecting COVID-19 will affect a person, but it’s possible to determine factors that can weaken the immune system. Here they are:8 Factors that May Weaken Your Immune System

  1. Certain medical conditions: diabetes, malnutrition, untreated HIV, leukemia, and multiple myeloma, rheumatoid arthritis, lupus, and multiple sclerosis.
  2. Medications: drugs for the treatment of autoimmune disorders, chemotherapy drugs, and steroids.
  3. Smoking.
  4. Stress.
  5. Lack of healthy sleep.
  6. Isolation, it can put a person at higher risk for mental health challenges.
  7. Poor diet: a traditional Western diet that is high in fat, sugar, and processed foods.
  8. Sedentary lifestyle: it weakens heart function and inactivity and obesity are associated with decreased immunity.

Body Clock May Have Crucial Influence on Immune System

A new study, conducted by the team of researchers from the Douglas Mental Health University Institute and the Université de Montréal, Canada, suggests that the body clock may have a great influence on the immune system. The study finds that the immune system responds differently throughout the day.Body Clock May Have Crucial Influence on Immune System

To come to this conclusion, the scientists working with two groups of mice one of which was genetically modified by switching off specific genes responsible for the regulation of circadian rhythms while the second group had these genes active.

With the help of a specific vaccine, the researchers found that in mice with a deficit of clock genes the response to the vaccine was diminished in the daytime.

Co-author Prof. Nathalie Labrecque says: “Our study shows that T cells are more prone to be activated at certain times of the day. Identifying the mechanisms through which the biological clock modulates the T cell response will help us better understand the processes that regulate optimal T cell responses.”

These 15 Foods Are the Best to Boost the Immune System

A human immune system consists of various cells, tissues, and proteins. In the system, they carry out the processes in our body that fight with pathogens — viruses, bacteria, and foreign bodies. When a pathogen comes into contact with the immune system, the latter releases antibodies to attack pathogens and kill them. The following fifteen foods will help you to boost your immune system:15 foods to boost immune system
