Humans are unable to digest cellulose because we lack the appropriate enzymes to break it down. While cellulose is not digestible, it is the fibre that aids in the smooth working of the intestinal tract. Eating cellulose foods helps aid healthy digestion and bowel movements. In addition, all foods with cellulose also contain other valuable minerals, proteins and vitamins.
Cruciferous vegetables, such as brussels sprouts, cabbage and kale, are high in cellulose. Our bodies have limited ability to access the nutrients encased in the cellulose structure, so most of what we eat of these vegetables is simply eliminated from the body. However, these vegetables are packed with other nutritious vitamins, minerals and fibre that make them valuable additions to a diet.
Tubers are vegetables such as potatoes, carrots and yams that grow underground. They are high in cellulose and starch. They are also rich in dietary energy and provide the body with complex carbohydrates.
Squashes such as pumpkin and zucchini are high in cellulose and low in sugar. They are similar to tubers in digestibility. They are a good source of vitamin A, vitamin C, calcium and iron.
Sprouts such as alfalfa and sunflower are high in cellulose and low in energy value. They are rich in minerals, amino acids and proteins.
