Nutrition for gastritis and reflux

Nutrition for gastritis and reflux is an adaptation of the diet that minimizes irritating foods, using a personalized approach to diet.

For a comprehensive overview, see the complete guide to proper nutrition — a fundamental manual from the expert team at Sport Zona.

What it is

Nutrition for gastritis and reflux is a specialized dietary approach aimed at alleviating symptoms and supporting recovery from these common gastrointestinal conditions. Gastritis is an inflammation of the stomach lining, which can be acute or chronic, while reflux (gastroesophageal reflux disease – GERD) is characterized by the backward flow of stomach contents into the esophagus, causing irritation and damage.

The main goal of this diet is to reduce stomach acid production, prevent irritation of the stomach lining and esophagus, and speed up the healing of affected tissues. This is achieved through a precise selection of foods and careful structuring of the diet, with an emphasis on individual tolerance and symptoms.

How it works

For gastritis and reflux, nutrition works by focusing on several key principles to reduce irritation and facilitate digestion. Firstly, it limits the intake of foods that stimulate excessive stomach acid production or relax the lower esophageal sphincter – the muscle that prevents stomach contents from flowing back. Secondly, foods that directly irritate the inflamed lining of the stomach and esophagus are avoided.

The main mechanisms include:

• Avoiding irritants: Giving up spicy foods, citrus fruits, tomatoes, chocolate, mint, caffeine, and alcohol, which can trigger or worsen symptoms.
• Reducing acidity: Preferring alkaline or neutral foods that help buffer stomach acid.
• Supporting digestion: Choosing easily digestible foods that do not burden the digestive system and reduce stomach emptying time.
• Regulating portion sizes: Eating frequent, small meals to avoid overfilling the stomach and putting pressure on the lower esophageal sphincter.

Why it's important for athletes

For athletes, nutrition for gastritis and reflux is critically important because these conditions can significantly compromise the training process and recovery. Symptoms such as heartburn, nausea, pain, and discomfort can interfere with effective training, reduce concentration, and worsen sleep, which is essential for muscle growth and recovery. Adequate nutrition is the foundation of energy levels, as well as the body's ability to adapt and recover. Uncontrolled gastritis or reflux can lead to insufficient nutrient intake, malabsorption, and micronutrient deficiencies, which directly affect athletic performance and overall health.

Proper diet adaptation allows athletes to maintain optimal energy balance and provide the necessary macro- and micronutrients without triggering unwanted digestive symptoms. For example, instead of consuming high-fat foods that slow stomach emptying (and are often triggers), athletes can focus on lean proteins (around 1.6-2.2 g/kg body weight for strength and endurance, according to ISSN), complex carbohydrates that are easily digestible (rice, oats), and moderate amounts of healthy fats. This keeps the digestive system in good condition and, moreover, provides stable energy levels and supports anabolism, which is key for muscle recovery and development, without compromising gastrointestinal comfort.

• FODMAP — Some FODMAP foods can cause or worsen gastrointestinal symptoms in sensitive individuals, which is relevant for managing gastritis and reflux.
• Mindful eating — Practicing mindful eating can help reduce symptoms of gastritis and reflux by eating more slowly and better recognizing satiety signals.
• Mediterranean diet — It is rich in fruits, vegetables, whole grains, and olive oil, which is beneficial for overall digestive health, although individual adjustments are needed for gastritis/reflux.
• Anabolism — Optimal nutrition for gastritis and reflux is important for maintaining anabolism in athletes by providing the necessary nutrients for growth and recovery without gastrointestinal discomfort.
