Can you prevent cold sores with diet?

Thank you for sharing. For most people the biggest lever is daily sun protection on the lips, even on cloudy days.

Winter is worse for me too, the cold cracks my lips first.

I noticed a big difference when I cut back on nuts and chocolate during stressful weeks and added more veggies, but honestly it's not a cure for me, more like it takes the edge off how often they show up. Everyone's triggers seem a bit different so it might take some trial and error to see what your body reacts to.

Honestly I thought cutting out nuts and chocolate would fix mine but it only helped a little; what actually made the biggest difference for me was just eating regularly and sleeping enough so my body wasn't run down.

Sleep makes a huge difference for me, more than I expected.

Honestly I noticed fewer outbreaks when I cut way back on nuts and chocolate during stressful weeks, though I have no idea if that was the food or just me finally sleeping properly. Worth a try but be kind to yourself if it doesn't fix everything.
