Are You Actually Chewing Your Food Enough? The Overlooked First Step in Digestion

Most people focus on what they eat, but how you eat matters just as much. Chewing is the first mechanical and enzymatic step in digestion, yet it is often rushed, incomplete, or done unconsciously. For people with inflammatory bowel disease (IBD), inadequate chewing can increase the burden on an already compromised digestive system, potentially worsening symptoms and affecting nutrient absorption.

What is chewing, and why does it matter?

Chewing, or mastication, is the process of breaking down food into smaller pieces using the teeth, tongue, and jaw muscles. This mechanical breakdown increases the surface area of food, making it easier for digestive enzymes to act on it later in the gastrointestinal tract. Chewing also mixes food with saliva, which contains enzymes such as amylase that begin the chemical breakdown of carbohydrates.

When food is inadequately chewed, larger particles enter the stomach and small intestine. These larger pieces require more time and enzymatic activity to digest, which can delay gastric emptying, increase fermentation in the colon, and place additional stress on an inflamed or healing gut lining.

How chewing affects gut inflammation and IBD

Reducing mechanical irritation

In people with Crohn’s disease or ulcerative colitis, the gut lining is often inflamed, ulcerated, or fragile. Poorly chewed food can physically irritate this vulnerable tissue as it moves through the digestive tract. Smaller, well-chewed particles are gentler on the mucosa, the innermost layer of the gut that is frequently damaged in IBD.

Improving nutrient extraction

Malabsorption is common in IBD, particularly during active inflammation or after bowel resection. Thorough chewing increases the bioavailability of nutrients by breaking down plant cell walls and releasing vitamins, minerals, and fatty acids. This is especially relevant for fat-soluble nutrients such as vitamins A, D, E, and K, and for omega-3 fatty acids, which are often supplemented in IBD management.

Minimising colonic fermentation

When large food particles reach the colon undigested, gut bacteria ferment them, producing gases such as hydrogen, methane, and carbon dioxide. This fermentation can cause bloating, cramping, and flatulence, symptoms that are already common in IBD. Excessive gas production may also increase luminal pressure and exacerbate discomfort. Chewing thoroughly reduces the substrate available for fermentation, which may help to lessen these symptoms.

Supporting enzyme efficiency

Saliva contains not only amylase but also lingual lipase, an enzyme that begins fat digestion in the mouth. The longer food is chewed, the more time these enzymes have to work. This early enzymatic activity reduces the digestive load on the stomach and pancreas, organs that may already be functioning suboptimally in people with IBD, particularly those with pancreatic insufficiency or bile acid malabsorption.

Encouraging mindful eating and symptom awareness

Chewing slowly encourages a more mindful eating pace, which can improve symptom recognition and help individuals identify trigger foods. Eating too quickly often leads to overeating, swallowing air (aerophagia), and poor digestion. Slowing down allows the body to signal satiety more effectively and can reduce the volume of food consumed in one sitting, which is beneficial for those managing strictures, bowel narrowing, or post-surgical changes.

How much chewing is enough?

There is no universal rule, but a commonly cited guideline is to chew each mouthful 20 to 30 times, or until the food is soft and nearly liquid. This varies depending on the texture of the food. Softer foods such as porridge or mashed vegetables require fewer chews, while tougher foods such as raw vegetables, nuts, seeds, and meat require more.

The goal is not to count every chew obsessively, but to develop awareness of the texture and consistency of food before swallowing. If you can still identify distinct pieces or lumps, more chewing is needed.

Practical takeaways

• Put your cutlery down between bites to slow your pace and give yourself time to chew properly.
• Chew until food is soft, smooth, and nearly liquid before swallowing, especially with fibrous or dense foods.
• Avoid eating while distracted by screens, work, or conversations that prevent you from focusing on the meal.
• Choose softer textures during flares, such as well-cooked vegetables, stewed fruit, and minced or flaked protein, to reduce the chewing burden.
• If you have strictures or narrowing in the bowel, prioritise thorough chewing and avoid large, fibrous, or indigestible food particles.
• Stay hydrated, but avoid drinking large amounts of liquid during meals, as this can dilute digestive enzymes and encourage faster swallowing.

Conclusion

Chewing is a simple, controllable step in digestion that is often overlooked. For people with IBD, taking the time to chew thoroughly can reduce mechanical irritation, improve nutrient absorption, minimise gas production, and support overall digestive comfort. It does not replace medical treatment or anti-inflammatory therapy, but it is a practical, cost-free behaviour that can complement clinical management and improve quality of life. Digestive health begins in the mouth, and giving your gut the best possible start may help to reduce the cumulative burden on an already inflamed system.
