5 Surprising Immunity Boosting Foods for Cold and Flu Season

over 2 years ago

According to the CDC's weekly FluView report, "flu activity continues to  increase in parts of the United States."  Additionally, my  super-scientific Sneezers on the Subway observations indicate that colds  are also on the rise. And while the CDC stresses that the best ways to prevent  the flu is to get vaccinated against it and wash your hands properly, there's  evidence that certain foods can help boost immunity and might help ward off  colds and the flu. Here are a few you might not know about:

Organic, Whole Milk: The findings of a just-released  study on organic milk and fatty acid composition, published in the  reputable peer-reviewed journal PLOS one, indicate that organic milk  contains a better balance of omega-3 to omega-6 fatty acids than conventional  milk. And omega-3s have been linked to tons of benefits, including  boosting immunity by increasing the activity of phagocytes, "cells that fight  flu by eating up bacteria," says Prevention. You'll also get the most omega-3s from  whole, rather than skim, milk though you'll have to weigh whether the extra  total fat and calories are worth it to you.

Pickled Turnips: "Scientists have discovered that eating a  traditional Japanese pickle could have 'protective effects' in preventing people  from catching the flu," according toThe Independent's recent article on the immunity boosting properties of a friendly  bacteria in the pickles called suguki. If you can't find suguki,  consider adding sauerkraut and kimchi to your menu --  the lacto-fermentation process by which these and some other traditional  pickled products are made produces probiotics (those good-for-you bugs most  associated with yogurt).

Red Grapes and Blueberries: These fruits may have "a significant benefit for immunity," according to a New York Daily News article reporting on an Oregon State University  study. "Findings published in the journal Molecular Nutrition and Food  Research showed that two compounds, resveratrol found in red grapes and  pterostilbene found in blueberries, when combined with vitamin D, could boost  the bodys ability to fend off illness." (Findings of a separate study,  published in BMJlinked blueberries, grapes, and apples to reduced risk of type 2  diabetes.)

Golden Kiwifruit: You might want to keep your eyes open in  exotic fruit section of the grocery store for this sweet, yellow-fleshed kiwi,  as a small study (funded by a fruit exporter, so take it with a grain of salt),  suggested that this fruit could help with congestion and sore throats.  (See The New Zealand Herald's "gold kiwifruit 'wonder drug' for colds" for more.) But  if you can't find the gold kiwis, don't worry: Regular kiwi is an excellent source of vitamin C.

"Five a Day": While many studies have drawn  associations between certain nutrients (e.g. vitamin C or E) and increased  immunity, the article Healthy  Diet Fights Infection by Boosting Immune System from the Tufts Health & Nutrition Letter cites a study in which participants who  increased their produce consumption from two to five servings per day of any fruit and vegetable saw increased immunity. Yet another reason to  eat a balanced diet filled with whatever fruits and vegetables you  love.
