Explanation:

Choosing beverages (especially non - sugary ones) and skipping desserts (which are often high in sugar) can both reduce sugar intake. An upset stomach is not guaranteed by these actions. They do matter for a healthy diet as sugar intake is an important aspect. And while desserts can have fat, the main commonality here is sugar reduction.
