Diet for COVID-19

21st treatment shown to reduce risk in June 2021

^*, now known with p < 0.00000000001 from 28 studies.

Lower risk for ICU admission, hospitalization, progression, recovery, cases, and viral clearance.

No treatment is 100% effective. Protocols combine complementary and synergistic treatments. ^* >10% efficacy in meta analysis with ≥3 clinical studies.

4,000+ studies for 60+ treatments. c19early.org

Analysis of 3,947 participants in Vietnam, showing significantly lower risk of COVID-19-like symptoms with physical activity and with a healthy diet. The combination of being physically active and eating healthy reduced risk further compared to either alone. The analyzed period was Feb 14 to Mar 2, 2020, which may have been before testing was widely available.

Background: Healthy eating and physical activity are effective non-pharmacological approaches to boost immune function and contain the pandemic. We aimed to explore the associations and interactions between physical activity and healthy eating behavior with COVID-19-like Symptoms (Slike-CV19S). Methods: A cross-sectional study was conducted on 3947 outpatients, from 14 February to 2 March 2020, at nine health facilities in Vietnam. Data collection included sociodemographic characteristics, healthy eating behavior (using the healthy eating score (HES) questionnaire), physical activity (using the short form international physical activity questionnaire), and Slike-CV19S. The associations and interactions were tested using logistic regression models. Results: Frequent

Supplementary Materials: The following are available online at https://www.mdpi.com/article/ 10.3390/nu13093258/s1; Table S1 : Confounders associated with suspected COVID-19 symptoms among outpatients (n = 3947), Table S2 : Spearman's correlation (rho) among potential confounders (n = 3947), Table S3 : Associations of underlying diseases with healthy eating behavior and physical activity among outpatients (n = 3947). Informed Consent Statement: Informed consent was obtained from all subjects involved in the study. Conflicts of Interest: The authors declare no conflict of interest.
