DIGESTIVE HEALTH IN THE ELDERLY

As people age, various changes in the digestive system can lead to discomfort, poor nutrient absorption, and general health decline. Digestive function slows down due to reduced enzyme production, weaker muscles, and slower gastrointestinal motility. To address this, elderly individuals should eat small, frequent meals, chew food well, and avoid heavy or greasy foods.

Stomach acid (hydrochloric acid) production decreases with age, affecting the absorption of vitamin B12, calcium, and iron. It is beneficial to include fermented foods, consider B12 supplementation, and pair iron-rich foods with vitamin C sources to improve absorption.

The output of pancreatic enzymes also drops, impairing fat digestion. Seniors should prioritize nutrient-dense foods and, if needed, take supplements—especially vitamins B12 and D—to counter deficiencies.

The gut wall, specifically the villi, becomes thinner and flatter, leading to reduced nutrient absorption. To support gut health, it is recommended to consume probiotics (e.g., yogurt, kefir) and prebiotics (e.g., bananas, garlic, dates), while also avoiding excessive antibiotics and processed foods.

The gut microbiota often becomes imbalanced with age, characterized by fewer beneficial bacteria. To help rebalance it, seniors should consume leafy greens (preferably cooked), fruits, nuts, fortified cereals, dairy, and oily fish such as sardines.

Due to slower digestion and chewing or swallowing difficulties, nutrient maintenance foods are vital. Seniors should aim for 4–5 small meals daily, with breakfast being the most important meal—rich in protein and fiber.

Large meals can cause discomfort or indigestion, so maintaining an appropriate meal frequency of 4–5 small meals, along with hydration and daily movement (e.g., walking), is essential. Seniors should also avoid excessive use of laxatives.

To prevent bloating, it’s best to avoid carbonated drinks, legumes, and fried foods, and to eat slowly. Drinking herbal teas such as ginger or peppermint may also help. Additionally, reviewing medications with a doctor, encouraging gentle physical activity, and limiting alcohol and caffeine intake are critical lifestyle adjustments.
