Which one makes alkaline urine?
Think it through first, then pick an option.

Answer and explanation
Correct answer: a Black plum
Black plum is a fruit, and eating fruit makes alkaline urine.
Why the other options are wrong
- b Lentil: Lentil is a protein food, so it raises the acidity of urine.
- c Peanut: Peanut is protein-rich; it does not make alkaline urine.
- d Bean seeds: Bean seeds are a protein food and raise acidity.
