Question on drinking instant nut and seed powders (those packaged in cans), and instant health oatmilk/multigrain beverages

Hello! Just wanted to ask if making high calorie drinks through mixing those powdered oatmilk/multigrain beverages and/or nut powders (sold in cans) and drinking them everyday is sort of a healthy way to gain weight?

I’m 23F Asian so these are accessible at my country’s grocery store (not sure if overseas have them)

Eg. of instant nut and seed powder sold in cans is like black sesame powder and pumpkin seed powder respectively. Link:
