Eating Accompanied by Words of Torah (part two)

Avot 3:3

מדרש שמואל says the phrase שלשה שאכלו seems to imply eating together is not ideal. Yet we have a principle that more people brings more honor to Hashem (ברוב עם הדרת מלך)? Why is it that eating needs be accompanied by words of Torah?

What we eat affects us. Why was Noach permitted to eat meat (only) after the flood?
