Foods That Help Reduce Acid Reflux Symptoms

Reviewed by Mostafa Damghani · 03/07/2026

Best Foods for Acid Reflux Management

Certain foods can help neutralise stomach acid and reduce reflux symptoms. Alkaline vegetables like broccoli, cauliflower, and leafy greens are excellent choices. Lean proteins such as chicken breast, fish, and turkey are easier to digest than fatty meats. Whole grains like oats, brown rice, and wholemeal bread provide fibre without triggering symptoms. Bananas and melons are low-acid fruits that many people tolerate well, whilst ginger can naturally soothe digestive discomfort.

Foods to Avoid When Managing GORD

Acidic foods often worsen reflux symptoms. Citrus fruits, tomatoes, and vinegar-based products should be limited. Spicy foods, chocolate, and mint can relax the lower oesophageal sphincter, allowing acid to escape upwards. Fatty and fried foods delay stomach emptying, increasing reflux risk. Caffeine from coffee and tea, along with alcohol, can irritate the stomach lining and increase acid production.

Eating Habits That Support Treatment

How you eat matters as much as what you eat. Consuming smaller, more frequent meals reduces pressure on the stomach. Eating your last meal at least 3 hours before bedtime allows proper digestion. Staying upright for 30 minutes after eating helps prevent reflux. Drinking water between meals rather than during them aids digestion.

When Dietary Changes Aren't Enough

Whilst dietary modifications can significantly help, some people may still experience persistent symptoms requiring medication. EverydayMeds offers various acid reflux treatments including omeprazole 20mg capsules, lansoprazole, and pantoprazole. These proton pump inhibitors can be used alongside dietary changes for optimal symptom management. Omeprazole is available over the counter in lower doses, though prescription-strength versions may be needed for severe symptoms. Always consult with a healthcare professional to determine the most appropriate treatment approach for your individual needs.

Can you buy omeprazole over the counter in the UK?
Yes, omeprazole 10mg tablets are available over the counter for short-term heartburn relief. Stronger 20mg doses typically require a prescription or online consultation. EverydayMeds offers both options through our pharmacy services.
Which foods should I avoid if I'm taking omeprazole?
Continue avoiding trigger foods like citrus fruits, spicy dishes, and fatty meals even when taking omeprazole. The medication works best when combined with dietary modifications. Alcohol should also be limited as it can reduce the medication's effectiveness.
How long does it take for dietary changes to help acid reflux?
Most people notice some improvement within 1-2 weeks of consistent dietary changes. However, healing of existing oesophageal damage may take 4-8 weeks, which is why medications like omeprazole are often prescribed alongside dietary modifications.
Can I stop taking omeprazole once my diet improves?
Never stop prescribed medication without consulting your healthcare provider. Some people can reduce their reliance on PPIs with successful dietary changes, but this should be done gradually under medical supervision to prevent symptom rebound.
What's the best eating schedule for acid reflux management?
Eat 4-5 smaller meals throughout the day rather than 3 large ones. Have your last meal at least 3 hours before bedtime, and avoid late-night snacking. This schedule helps prevent excessive stomach pressure and nighttime reflux episodes.
