According to the study’s authors: “Plant-based dietary patterns are rich in antioxidants, phytosterols and polyphenols, which positively affect several cell types implicated in the immune function and exhibit direct antiviral properties.”

Now, it’s worth noting that this study was entirely observational, meaning the researchers did not measure the impact of the diets on the participants, but it still adds to pre-existing research that suggests eating more plants could have a positive impact on immune health.

Not only do we know that the nutrients in plants are fantastic for supporting our immune system, but we also know that eating more plants can support a diverse and healthy gut microbiome, which research has shown to be directly linked to immunity.

Why following a vegetarian, vegan or flexitarian diet is good news for your immune health
