Your opinion about use of Olive Oil, do we really need to use it?"

[Paper Roses]

I follow a couple of cooking videos on FB. I especially like: https://www.sipandfeast.com/.
Great recipes for Italian food plus other recipes. The host is great and shows everything you need to know about what he is preparing.
My problem: I don't care for the taste of Olive Oil. I wonder what the difference would be with corn oil or Canola oil.
Plus, like many other cooking pages, there is a ton of Garlic used. Do we really need 5 or 6 cloves to make a simple recipe? Jacques Pepin also uses a ton of garlic. There are social implications. 6 cloves of garlic...yikes, I might need a triple mask just to get close to the person to whom I am speaking..

Would love to hear any thoughts.

I have enough trouble dividing the recipes for just me. Sure miss the days when the whole family was here for meals.
