Discussion Overview

The discussion revolves around the effects of drinking liquids while eating on digestion. Participants explore whether consuming liquids during meals influences saliva production and overall digestive efficiency, considering various perspectives on timing and the role of saliva and digestive fluids.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants question whether avoiding liquids while chewing could enhance saliva production, potentially benefiting digestion.
  • Others argue that saliva's role is limited to the mouth and esophagus, suggesting that water intake may be more beneficial after swallowing food.
  • A participant recalls that drinking too much liquid could dilute stomach juices, though the impact on saliva production remains unclear.
  • Concerns are raised about the effects of high pH liquids on digestion, with some suggesting that they may hinder protein digestion by neutralizing stomach acid.
  • Some participants assert that saliva is primarily water and may not be significantly influenced by drinking during meals.
  • There is a discussion about the natural eating habits of animals, with some participants drawing parallels to human eating practices and weight management.
  • A participant mentions personal experiences with drinking while eating, indicating no digestive issues but expressing uncertainty about the best practices.
  • Some participants highlight the potential risks of drinking while chewing, such as choking, while others suggest that sipping water between bites could aid in digestion.

Areas of Agreement / Disagreement

Participants express a range of views on the topic, with no consensus reached regarding the best practices for drinking liquids while eating. Multiple competing perspectives remain on the influence of liquids on digestion and saliva production.

Contextual Notes

Some claims depend on assumptions about the digestive process and the role of saliva, which are not fully resolved within the discussion. The varying definitions of when drinking occurs (during chewing vs. between bites) also contribute to the complexity of the topic.

Is it advisable to not drink any liquids when chewing food? would that allow more saliva to develop as oppose to taking sips with every intake of food? And if more saliva develops would it be better for digestion?

Digesive fluids do help with digestion, but often there is not enough to wash the food down into the stomach or to quench thirst.

If you have chewed properly, enough saliva should have been dispensed to properly digest the food.
 
Saliva only aids in the digestion of food until it reaches the stomache. The amount of saliva produced would be more to do with the length of time the food was chewed for rather than if there was a presence of another liquid (although I'm just guessing). However, seeing how water is needed for the chemistry of digestion, it would improve digestion to increase the water intake during or immediately following a meal.
 
So is it better to drink during chewing or after the food has been swallowed? I thought that saliva aided digestion, so if you were to secrete more of it the better for you stomach.
 
As I recall from biology, saliva works in the mouth and esophagus; but the pH of the stomache deactivates it from working further. I don't know which would be better; to drink during chewing or after chewing, but if I had to guess i'd say immediately after swallowing. Although I have no basis for that.
 
My parents never allowed me to drink during diner. Depending on how much you drink, you do dilute your stomach juices. I don't know what the effect of drinking is on saliva production.
 
It's a little off topic, but I do know that drinking high pH (basic) liquids, or eating foods that have a high pH hampers the effectiveness of digestion. The pH difference neutralizes a portion of the stomaches acid and reduces the digestion of substances that rely on an acidic environment to be broken down. As I recall, proteins are digested by the acids in the stomache, then upon entering the intestinal tract the pH changes from acidic to alkaline and carbohydrates and fats are digested by the high pH bile in the small intestine.

So, one could infer that consuming alkaline foods or liquids, or even just diluting the stomache acid with a large amount of water, would affect the efficiency of protein digestion.
 
Saliva is mostly water isn't it? I do not believe that drinking while eating influences saliva production nor does it have that much of an affect on the enzymes.

Not by acids, but by pepsin, digestive enzyme. Pepsin needs very low pH.

That's right yes. All I could remember was the connection between low pH and protein. :)

I noticed many years back that I stopped salivating when I'm full.
It's the bodies way of telling you you've had enough to eat.
A lot of people think I'm rude, or that I'm a freak because I now refuse to drink anything during my meals.

This may be one factor that explains why I'm not overweight, as are 5 of my 6 siblings.

You might look to nature for something as basic as eating habits. How many creatures, besides man, eat and drink at the same time? Racoons maybe. But look how fat they are.

I've always drunk while eating (in fact everytime I felt thirsty). Sometimes while chewing but mostly just after swallowing/ just before swallowing. I've never had any problem with my digestion, I never took any pills for that.
Maybe should you follow what your brain wants (if you're thirsty, drink.), but I'm not sure if it's the best.

Ah ha! More proof.

Eskimo's eat whale and seal "blubber" = fat.

And who's ever seen a skinny beaver?

Dolphins and otters may keep trim with constant exercise.
They do seem always on the move.

That would explain why my one sibling is not overweight, he spends half the day in the gym.

Most animals eat raw food - when you cook food you drive off water, which has to be replaced with water you drink.

Just so we're clear here, did anyone else notice that this is a thread about drinking while eating?
 
  • #16
I'm not quite clear on whether the OP is talking about drinking while having a mouthful of food being chewed, or just while sitting down to a meal. In the former case, that seems a bit impolite and perhaps puts you at risk of choking if you're trying to chew and drink at the same time. But, nothing wrong with taking a sip of water between bites. It might even help you eat less if you fill your stomach with some water and slow down your eating a bit.

How did humans survive before they had PF to tell them the procedure for eating?!

But that doesn't mean that what you are doing naturally can be optimal for you.

They died?

My favorite saying from when I was 14, from a friend's professor - masticating to peptic euphoria. It always reminded me to carefully chew my food.

Yes, whenever I eat raw foods like a spoonful of fresh ground peanut, or cashew butter, i cannot swallow without choking. Is it only me? I was thinking maybe our saliva is not enough to wash down these lipid-rich foods.. I need to combine them with something higher in moisture, like jam, milk, water, fruit..
