Your body cannot digest dietary fiber, especially the cellulose in plant cell walls (like in grass, seeds, fruit skins), because humans lack the necessary enzyme (cellulase) to break it down, though it's vital for digestion as roughage, promoting bowel health and blood sugar control, with some minimal breakdown possible by gut bacteria. Certain individuals also struggle with specific things like lactose (dairy sugar) or artificial sweeteners.
Insoluble fiber is what we think of as roughage. This is the material from food that your body cannot break down in digestion, so it leaves the body pretty much as it goes in. Foods high in insoluble fiber include: Skins and seeds of fruits and vegetables.
This is because fiber – which is often considered a healthy part of the diet – is often found in fruits, vegetables, and grains, and is not digested by your body. As a result, fiber passes through our large intestine and can cause several problems, from gas, bloating, to difficult stools.
The correct answer is Cellulose. Cellulose is a carbohydrate molecule. It can be only digested by ruminant animals. Humans can not digest it.
Fatty foods, such as chips, burgers and fried foods, are harder to digest and can cause stomach pain and heartburn. Cut back on greasy fried foods to ease your stomach's workload. Try to eat more lean meat and fish, drink skimmed or semi-skimmed milk, and grill rather than fry foods.
The hardest foods to digest are typically fried and fatty foods, processed foods, and items high in certain fibers or sugars, like cruciferous vegetables, legumes, onions, garlic, and dairy (for the lactose intolerant), as well as red meat, due to their fat content, complex fibers (like cellulose in corn), or FODMAPs, slowing stomach emptying and potentially causing gas, bloating, or cramps.
The human digestive tract cannot break down cellulose. Corn passes through your system undigested; as such, it can cause cramps, abdominal pain, and gas in the process.

Protease: It helps in protein digestion and includes pepsin, trypsin, chymotrypsin and carboxypeptidase are produced by stomach and pancreas. Hence option C is correct Liver doesn't produce any digestive enzymes. Hence, the correct answer is option C.
High-fat foods
Deep-fried foods contain a lot of fat, but so do a lot of other foods that aren't fried. Heavy cream, butter, and fatty meats, such as bacon, can all be very hard to digest, which can result in cramps, bowel issues, and other digestive issues.
A peanut butter and jelly sandwich (PB&J) adds about 33 minutes to your healthy lifespan per serving, according to a University of Michigan study that measured life expectancy impacts of over 5,850 foods using the Health Nutritional Index (HNI). This sandwich tops the list for adding time, with nuts and seeds also being highly beneficial (around 25 mins) and processed items like hot dogs subtracting time.
There's no single "number 1" unhealthy food, but ultra-processed items like sugary drinks, processed meats (bacon, hot dogs), deep-fried foods (fries), and refined snacks (donuts, chips, sugary cereals) consistently top lists due to high sugar, salt, unhealthy fats, and additives linked to obesity, heart disease, and diabetes. These items offer little nutritional value while increasing risks for chronic diseases.
In The Article
The covering of each delicious kernel of corn is insoluble. This is the undigestible kind that the body cannot break down and that passes through the body more or less intact, which can add bulk to bowel movements and ease constipation.
The 10 most constipating foods often include dairy products, red meat, fried foods, processed foods/fast food, white bread/refined grains, sugary snacks, unripe bananas, chocolate, alcohol, and caffeine, primarily because they are low in fiber and high in fat, sugar, or compounds that slow digestion, leading to harder, slower stools; adding fiber and fluids helps prevent constipation.
To harden stool, focus on bland, low-fiber foods like the BRAT diet (bananas, rice, applesauce, toast), white pasta, potatoes, and cheese, as these help bind stool by being easily digestible and low in residue, with options like crackers, oatmeal, and smooth peanut butter also working well.
Unripe (Green) Bananas
Green bananas contain high levels of resistant starch. Resistant starch is not easily digested by the small intestine. Instead, it moves to the large intestine, where gut bacteria ferment it. While resistant starch can be beneficial in moderation, it can be binding.
Second, they found that steaming significantly improves the bile acid binding of collards, kale, mustard greens, broccoli, peppers, cabbage, as well as beets, eggplant, asparagus, carrots, green beans, and cauliflower, suggesting steaming vegetables may be more healthful than those consumed raw.
Key Takeaways. Easy-to-digest foods are typically foods high in protein, low in fiber, and soothing on the GI tract. Bananas, eggs, and applesauce are among the easiest foods to digest.
Here are a few to keep an eye on:
All fruits contain fructose, a sugar that can be difficult to digest for people with IBS and other GI disorders. Dried fruits, apples, and pears have higher fructose levels than other fruits, which can cause lactose intolerance-like effects in people with IBS.
Foods to Avoid
Easily digestible foods include bananas, baked skinless poultry or fish, white rice, broth, herbal teas, and more, but what's easy for one person to digest may be different from what works for the next person.
Including yogurt in your diet can be beneficial for your digestive system. Its probiotic content aids in digestion, reduces bloating and constipation, and may even help those with lactose intolerance. However, remember to choose natural, low-fat yogurts with live and active cultures to reap maximum digestive benefits.
