Which one of the following pairs of food components in humans reaches the stomach totally undigested?

1. Starch and fat
2. Fat and cellulose
3. Starch and cellulose
4. Protein and starch

Correct answer: Fat and cellulose

Solution

Cellulose is not digested by human enzymes at all, so it reaches the stomach unchanged. Fat also remains essentially undigested in the stomach because most fat digestion occurs later in the small intestine, not in the stomach.
