I have heard that having carbonated drinks after having a non-veg meal is good.. is it?

Even i have heard that, i think the logic behind is that carbonated drink helps in digestion. So the "not-easily" digested non-veg food can be digested better.

Carbonated drinks are not at all good for human body.
They interfere with the digestion process.

not at all true... and also go through the following things that DONTS after meal...

Don't smoke- Experiment from experts proves that smoking a cigarette after meal is comparable to smoking 10 cigarettes (chances of cancer is higher).

* Don't eat fruits immediately - Immediately eating fruits after meals will cause stomach to be bloated with air. Therefore take fruit 1-2 hr after meal or 1hr before meal.

* Don't drink tea - Because tea leaves contain a high content of acid. This substance will cause the Protein content in the food we consume to be hardened thus difficult to digest.

* Don't loosen your belt - Loosening the belt after a meal will easily cause the intestine to be twisted & blocked.

* Don't bathe - Bathing will cause the increase of blood flow to the hands, legs & body thus the amount of blood around the stomach will therefore decrease. This will weaken the digestive system in our stomach.

* Don't walk about - People always say that after a meal walk a hundred steps and you will live till 99. In actual fact this is not true. Walking will cause the digestive system to be unable to absorb the nutrition from the food we intake.

* Don't sleep immediately - The food we intake will not be able to digest properly. Thus will lead to gastric & infection in our intestine.

Carbonated drinks releases the formed gas in the stomach, thus prevents from the feeling of fullness and hence symptoms like belching, nausea etc doesnt occur.

However carbonated drinks are rich in pseudocalories that means it is of high caloric value with minimum nutritive character, hence it is equally helpful in causing diseases realted to high calorie and is harmful in person with diabetes, hypertension, heart disease and obesity.

Carbonated drinks have preservatives added to them. Logically speaking, when we look at soft drink expiration date on the bottle cap, we see that the drink can be consumed approximately for about an year. This shows that preservatives are added to the drink that allows it to be preserved for about an year. Any artificial ingredient is hazardous to health.
