Micronutrients (vitamins and minerals) and phytonutrientsthat are primarily available in fruits, nuts, vegetables andwholegrains enhance both native and adaptive immune functionand prevent infection among others, the Indian Council ofMedical Research (ICMR)-National Institute of Nutrition (NIN)here said.
The over a century-old NIN, which has attained globalrecognition for its pioneering studies on various aspects ofnutrition research, has given its suggestions to the Centre onnutrition and immunity in the backdrop of the fight againstcoronavirus and sent them to the Centre, it's DirectorHemalatha R said. It has also recommended the amount of food to bedistributed as free ration for the economically deprived,daily wage earners and migrant workers during the ongoinglockdown to keep them food and nutrition secure during thesetough times, she said.
Micronutrients also aid immune memory formation thathelps prevent reinfection with the same pathogen, helpscavenge toxins produced in large quantities in the bodyduring infection and immune response, and increase beneficialprobiotic bacteria in the intestine among other benefits,Hemalatha told here.
Fruits like papaya, guava, apple, grapes, mango,oranges, tangerines, lemons, sweet lime and goose berries, allseasonal vegetables, including green leafy, and spices,legumes, millets, flesh foods and fish are among those withrich sources of nutrients, she said.
