1) The proposal is for an animated video interviewing the creator's mother about her experience going vegan, including the effects on her diet, substitute foods, new recipes, and learning about her histamine intolerance. 2) The video will begin with quickfire questions about veganism, include facts about being vegan from the mother, and explain pros and cons like checking labels. 3) It will end by discussing how the mother discovered her histamine intolerance, how it affects her vegan diet, and which foods to avoid or enjoy with the intolerance.
