Singapore's Health Minister, Mr KHAW Boon Wan, recently had heart surgery. Upon returning to work, he blogged about his new diet.
Here's the relevant paragraph:
Second: I have adopted a fully plant-based diet plan, avoiding all meat, not even fish or dairy products. Today's lunch was bought from SGH food court: salad with no dressing, vegetable sandwich (on wholegrain bread) and fruits. (This morning's breakfast was oats, wholegrain bread and fruits.)
