Food and Liquids combined

I heard from a nutritionist student that high amounts of liquids should not be consumed with meals. Here is the reasoning..

1) water dilutes stomach acid and enzymes necessary for digestion.
(but how would acidic drinks like soda effect this?)

2) cold drinks with fatty food especially should be avoided because the low
temperature causes the fat to "gel" or solidify (didn't say why, but I guess
may increase the chance/amount of it being stored/deposited in the body).

(Doesn't the body naturally supply the stomach with heat though, and is
it not ample enough to account for cold liquids?)

If you have any insight on whether these 2 ideas are true or false, and why, please speak up. thanks

I just recently read this too. Not sure where or why I read it.

I'm more skeptical about the cold water one, though.

I think the article or whatever said that drinking a glass of water 20 minutes before a meal was actually healthy.
