There’s no denying that cold and flu season is upon us! I won’t lie… I get a little nervous (or
germophobic if you’re into labels) when I hear sniffling and coughing from
someone standing a little close on rounds or the subway. The good news is that a healthy diet keeps
your immune system functioning well and may help prevent or shorten the
duration of your cold. Here’s some
information on the key players in your battle.
Vitamin C
-
~200mg/d helps fight colds
-
Food sources: fruits and vegetables, like sweet peppers, strawberries, kiwi, oranges,
broccoli
Zinc
-
Consumption within 24h of getting a cold may
help you have fewer symptoms
-
Food sources: oysters, seafood, fish, beef,
pumpkin seeds, baked beans
-
If supplementing, do NOT take >40mg/d
Probiotics
-
‘Good’ bacteria that keep your immune system healthy
-
To fight colds, dose should be ~10 billion active
probiotic cultures per day, starting 3 months before cold season starts
-
Food sources: yogurt with added probiotics
-
Look for the following strains to help colds:
o
Lactobacillus gasseri, CECT5714 or PA16/8
o
Lactobacillus acidophilus, 74-2 or NCFM
o
Lactobacillus casei, DN 114
o
Bifidobacterium longum, SP07/3
o
Bifidobacterium bifidum, MF 20/F
Before taking supplements, remember to check with your
doctor or pharmacist and ensure you purchase ones that have Natural Product
Numbers (NPN) from Health Canada.
