Flavonoid groups of compounds are naturally found in fruit, vegetable, chocolate, wine, tea, and other such things. They, like other plant-based nutrients, are powerful antioxidants. Antioxidants — as we have seen earlier — are anti-inflammatory and strengthen the immune system. These nutrients have been used, and their benefits mentioned in ancient herbal systems like Ayurveda and Chinese medicine.
Flavonoids are used in foods and pharmaceutical supplements (Yao et al., 2012). This class of molecules was shown to provide a degree of protection in colon cancer patients (Kurzawa-Zegota et al., 2012).
A plant-based diet is a healthier alternative to one laden with meat; It reduces the chances of artery blockage and artery hardening, which are common causes of heart attacks (Tuso et al, 2015; Hu.,2003). It’s been observed that subjects who follow a plant-based diet (especially legumes) have high levels of genistein in their urine. Genistein is also said to help prevent chronic degenerative diseases like cancer tumors (Fotsis et al., 1993).
Fiber supplementation in obese individuals significantly enhances weight loss. Increased fiber intake benefits gastrointestinal disorders conditions like gastroesophageal reflux disease, duodenal ulcer, diverticulitis, constipation, and hemorrhoids. Prebiotic fibers have been observed to enhance immune function (Anderson et al., 2009).
Similarly, there are many herbs and herbal combinations that are immunity boosting. There is no scientific study in support of plants helping heal COVID 19 infected patients.
