After I eat some foods beer tastes weird? I'm an obsessive home brewer.  So I'm always trying to critically evaluate the flavour of beers I make with a view to constantly improving their quality. In particular I am searching for off-flavours, like by-products of fermentation, or is some-ingredient too prominent in the flavour profile.

However I find that if I eat certain foods (like flavoured chips/crisps), before drinking beer, some parts of the malt taste profile (or the yeast?) flavours go weird, the sweetness becoming kind of saccharine (maybe). 

Some foods do not prompt this at all, e.g.: unflavoured corn chips/crisps, salted peanuts.

Is this a known phenomenon? 
Is there a way to "reset" one's palette?

Maybe I should post this to the alcohol section.  But this is really a question about food &amp; flavours.  I'd like to prepare meals (and snacks) that don't make beer taste weird.

EDIT: I tested this out over the weekend.  I tasted beer - it's good, ate "Cheese &amp; Onions Chips" (crisps), beer then tastes weird.


Rinsing my mouth with lots of water alleviated it quite a bit.
Drinking Milk didn't seem to do anything.
Eating plain bread (suggested elsewhere) didn't seem to do anything.


I will try the High Salt rinse next.
Even sugars can affect the flavour of the next mouthful or two. This includes the dextrose added to quite a lot of savoury snacks (and similar foods, often before cooking so it caramelises), which might explain why some crisps (chips) have this effect and others don't. I find that a couple of small sips are enough to restore taste to normal. 

Without rigorous testing I find that this reduces the flavour of a malty beer. More hoppy beers tend to taste more bitter after certain foods, but mainly sweet foods, so I've always put that down to the contrast in flavours. Again this is a short-lived effect.
