The honest version
Acid reflux advice is full of confident lists of foods to cut out forever. The research tells a messier story: a handful of changes have solid backing, a few popular fixes are surprisingly weak, and one common one can even make things worse. Here's what actually holds up.
1. Raise the head of your bed
Research: StrongLying flat lets stomach acid sit right at the valve between your stomach and oesophagus. Raising the head of the bed by roughly 15–20cm — with bed risers or a wedge, not just extra pillows stacking your neck — has shown a meaningful drop in nighttime reflux symptoms in trial data, even though study quality varies. It's cheap, low-risk, and one of the better-supported changes on this list.

2. Give your last meal time to settle before you lie down
Research: ModerateEating close to bedtime is one of the more consistent risk factors researchers have found for nighttime reflux — a shorter gap between dinner and lying down has repeatedly tracked with more symptoms. Lying down with a full stomach makes it easier for acid to press up against the valve that's supposed to keep it in the stomach. A gap of around three hours is the figure most often cited.

3. Losing extra weight, if you're carrying it
Research: StrongThis is one of the best-supported levers in the whole list. Extra abdominal weight pushes up on the stomach and raises the odds acid gets forced past the valve. In trial data, people who lost around 10% of their body weight through diet saw a real drop in symptoms and reduced how much reflux medication they needed — and the effect showed up in studies with thousands of participants, not just small samples.

4. Trigger foods are more personal than the lists suggest
Research: ModerateCoffee, alcohol, chocolate, and spicy food are the usual suspects, and there are real mechanisms behind the warnings — caffeine and chocolate can relax the valve that keeps acid down, and spicy food can directly irritate an already-sensitive oesophagus. But when researchers actually test these foods against symptoms across groups of people, the pattern is inconsistent — reviews have found coffee intake, for instance, isn't reliably linked to more reflux at a population level. The practical approach that holds up best is tracking your own triggers rather than cutting out a list, since the same food doesn't affect everyone.

5. Smaller, more frequent meals
Research: ModerateA large meal stretches the stomach and raises the pressure pushing against the valve above it. Splitting the same amount of food into smaller portions across the day is a common recommendation in gastroenterology guidance, though it's rarely been isolated and tested on its own in a large trial — it's usually one part of a broader lifestyle package.

6. Alginate antacids, for fast relief
Research: StrongAlginate products (like Gaviscon) work differently to a standard antacid — they react with stomach acid to form a floating gel "raft" that physically blocks acid from splashing up into the oesophagus. In head-to-head trials they've matched omeprazole for symptom relief in mild-to-moderate reflux, and a systematic review found they outperform plain antacids. Good option for occasional or mild symptoms rather than a nightly medication.

7. When lifestyle changes aren't enough: H2 blockers and PPIs
Research: Very strong (PPIs)Proton pump inhibitors like omeprazole are the most effective acid-suppressing medication available, backed by some of the largest and most consistent trial evidence in gastroenterology. H2 blockers like famotidine work faster but suppress acid less completely — still well-supported, and often used for milder or occasional symptoms. The caveat worth knowing: long-term PPI use has been linked in observational studies to a higher risk of certain infections, fracture, and other issues. That doesn't mean short courses are risky, but it's a reasonable prompt to check in with a doctor before treating them as a permanent fixture rather than a treatment for a flare.

8. The natural options: DGL and ginger tea
Research: LimitedDeglycyrrhizinated licorice (DGL) — licorice root with the blood-pressure-raising compound removed — has shown promising results in a few small, industry-linked trials, but the overall evidence base is thin. Ginger is the more surprising one: despite its popularity as a stomach-settler, the research on ginger specifically for reflux is sparse and mixed, and some reviews note that larger doses of ginger can actually trigger heartburn in some people rather than easing it. Reasonable to try, but don't expect it to outperform the options above.

The bottom line
The changes with the strongest backing here aren't exotic — elevating your bed, losing extra weight if you're carrying it, and giving your stomach time to empty before you lie down. Trigger foods are worth tracking, but the one-size-fits-all avoid lists overstate the evidence. And if you're reaching for medication most days, that's worth a conversation with a doctor rather than a permanent routine — reflux that needs daily treatment deserves a proper look, not just management.
