Some people have health challenges that make several foods difficult for them to digest. It is important to meet a dietician, to help make healthy choices to prevent exacerbation. The body requires various nutrients such as fiber, protein and fat. In some conditions, these nutrients are difficult to digest.
Eating foods that have low fiber content reduce the amount of undigested substance and may relieve the symptoms.
The following foods are easy to digest:
Toast is easier to digest than bread, because the toasting process degrades some of the carbohydrates. Toast are very useful in reducing nausea  and heartburn.  However, it is important for people to know that not all toast is the same.
Whole wheat bread has more health benefits than white bread, but it has high fiber content and can be difficult for people to digest.
People with difficulties digesting whole wheat toast are advised to eat it plain without any butter. You can add fruit jellies over creamy spreads such as nut butter to increase the flavor.
People who cannot digest whole grains can try enriched white bread. Its nutrients depend on the type. Two slices of enriched white bread may contain:
- 140 calories
- 44 mg of iron
- 2 micrograms (mcg) of folate
- 4 g of protein
- 29 grams (g) of carbohydrate
- 2 milligrams (mg) of calcium 
- 1 g of fiber
Small slices of plain, white toast without spreads are mostly the best option for some patients. People who cannot tolerate wheat or gluten can pick a wheat-free or glute-free bread option.
Whea-free or gluten-free bread can be bought in many grocery stores or online shops.
