3. Cranberries
These berries are well-known for being tangy but sweet at the same time, making them a very good choice of snack instead of something sugary. If you're needing to watch your kidneys on a diet, fret not; these berries promotes gastrointestinal health and protects against heart disease and some cancers. Bacteria is less likely to form in the stomach as well.
Dried cranberries make a great snack alone, or you can add them to a salad to introduce a new flavor. Cranberry sauce is another preferred method of consumption. There's also cranberry juice, but you'll need to moderate for sugar consumption.
