Free time project - data visualisation training combined with my interest for diet. Reddit post: https://www.reddit.com/r/dataisbeautiful/comments/8fyu1i/vitamin_c_in_some_common_foods_oc/

I handpicked particular foods based on my research and experience. These are either foods which allow you to get your vitamin C most easily (red bell peppers, oranges, broccoli) or popular foods that have less vitamin C than most people would expect (tomatoes, apples, blueberries).
I used Recommended Daily Allowance for men - 90 mg (for women it is less - 75 mg). There are reasons to suspect though that 200 mg is a better amount to be getting - then the adjusted plot would look like this.
Values in grams (peel not accounted for):
- 1 medium red bell pepper - 119 g
- 1 medium orange - 131 g
- 1/2 medium broccoli - 90 g
- 1/2 cup strawberries - 76 g
- 1 medium tomato - 123 g
- 1 medium banana - 118 g
- 1 medium apple - 182 g
- 1/2 cup blueberries - 74 g
