To support your immune system, which is extremely important in conditions of global coronavirus outbreak, you should eat a balanced diet containing adequate protein, fiber, vitamins, and minerals. These are eight foods and food groups that help you to keep your immunity in order:
Almonds: rich in vitamin E, which is important for supporting the immune system, a good source of protein and healthy fat.
Bell peppers: rich in vitamin C, which takes part in forming antibodies that fight illnesses.
Broccoli: contains a lot of antioxidants, vitamins A, C, E (and) potassium, as well as healthy fiber.
Citrus fruits: have such benefits as anti-inflammatory and antioxidant effects.
Dark leafy greens: a good source of beta carotene which takes part in reducing inflammation and increasing disease-fighting cells.
Garlic: contains compounds that destroy bacteria and infection.
Pumpkin seeds: a great source of zinc, which is crucial for immune cell functioning.
Red peppers: contain as much vitamin C as citrus fruits.
Recent research from the University of Bonn finds that a high-salt diet is not only bad for the blood pressure but it also weakens the immune system.
During the study, the scientists noted that mice that were fed a high-salt diet suffered from much more severe bacterial infections than those eating their normal ration. Also, the human volunteers who consumed an additional 6 grams of salt per day also demonstrated pronounced immune deficiencies.
Prof. Dr. Christian Kurts from the Institute of Experimental Immunology at the University of Bonn says: “We examined volunteers who consumed six grams of salt in addition to their daily intake. This is roughly the amount contained in two fast-food meals, i.e. two burgers and two portions of French fries.”
When after one week of this diet the scientists took blood from the volunteer and examined the granulocytes they noticed that the immune cells coped much worse with bacteria after the test subjects had started to eat a high-salt diet.
According to a new study from Arizona State University, US, probiotics may promote weight loss and treat obesity in gastric bypass patients.
For the study, a team of researchers characterized the microbial communities in 9 people with severe obesity before the gastric bypass surgery and 6 months after the procedure. They also compared the microbial communities with the communities in 10 control subjects and 24 people who had this surgery 13–60 months previously.
Co-author of the study Prof. Rosa Krajmalnik-Brown comments on the results of the study: “Understanding the microbial behavior in the gut could potentially lead to creating a probiotic that could replace surgery — or an improved indicator to identify the best candidates for surgery and sustained weight loss.”
A new study, carried out by researchers from the University of California in San Francisco, US, finds that people who walk more also have lower blood pressure.
For the study, the scientists analyzed data provided by 638 participants within the study called the Framingham Heart Study. The participants were prescribed to wear an Apple Watch every day for at least 5 hours.
The device recorded the number of steps made every day. Also, all the participants had to measure their own blood pressure on a weekly basis at home during the study period (5 months).
Lead author Dr. Mayank Sardana says: “This study solidifies our understanding of the relationship between physical activity and blood pressure and raises the possibility that obesity or [BMI] accounts for a lot of that relationship. […] It would be useful to look at how smart devices might be leveraged to promote physical activity, reduce the burden of obesity, and potentially reduce blood pressure.”
A new study, performed by researchers from the United States and the United Kingdom, finds that age-related changes in the brain start earlier than it was previously thought and switching to a low-carb diet may reverse the deterioration.
To determine when changes to the brain start, the researchers used two large-scale functional magnetic resonance imaging (fMRI) datasets. The analysis of these MRIs showed that the changes to the stability of a neural network emerged already at the age of 47, and the brain degenerated fast from the age of 60 years.
To study how the type of diet influences the brain network stability, the researchers integrated 42 volunteers aged under 50 into their study. The team used MRI machine to measure their neural activity.
The study participants were divided into two groups one of which ate a low-carb diet, and another ate a regular diet with overnight 12-hour fasting.
The researcher Mujica-Parodi, a professor in the Department of Biomedical Engineering, says: “… the good news is that we may be able to prevent or reverse these effects with diet, mitigating the impact of encroaching hypometabolism by exchanging glucose for ketones as fuel for neurons.”
