GERD and reflux
Most reflux advice is a list of foods to avoid. The evidence for those lists is much weaker than their popularity suggests, and the things that actually work — weight, meal size, timing, and what you do in the three hours before bed — get mentioned last. If reflux has persisted on medication, the pattern is usually the place to look before the food is.
What is actually happening
The valve between oesophagus and stomach is meant to stay closed except when you swallow. In reflux it relaxes when it should not, or is overwhelmed by pressure from below, and stomach contents move upward into a tube with none of the stomach's protection. Hence burning, an acid or bitter taste, chest discomfort, and for many people a cough, hoarseness or throat clearing that never gets connected to the gut at all.
Three things drive it more than diet does: pressure inside the abdomen, how full the stomach is, and gravity. That is why the interventions below are ordered the way they are.
What has the strongest evidence
- Weight, where there is excess to lose. This has the best evidence of any dietary intervention in reflux, and it is mechanical rather than mysterious: abdominal weight raises the pressure pushing against a valve that is trying to stay shut. Modest losses often produce disproportionate relief.
- Meal size. A full stomach refluxes. Smaller meals more often beat large ones, whatever is in them.
- Timing before lying down. Roughly three hours upright after eating, consistently. This is the single change most people have never actually tried properly, and one of the most effective.
- Raising the head of the bed — the bed frame, not extra pillows, which bend you at the waist and can make it worse.
- Alcohol, and smoking. Both relax the valve. Both are worth testing before a long list of foods is.
About the trigger list
Coffee, chocolate, citrus, tomato, mint, fatty and spicy food are on every reflux list in existence. The evidence that removing them helps is much thinner than the lists imply, and triggers turn out to be strikingly individual: the food that reliably sets off your reflux may do nothing to anyone else.
Which argues for testing rather than obeying. Remove a suspected trigger deliberately, for a defined period, then reintroduce it and watch — rather than cutting nine foods at once and never finding out which one, if any, mattered. Most people end up restricting one or two things instead of nine.
Reflux that persists on medication
Acid-suppressing medication reduces how acidic the reflux is. It does not stop the reflux itself. That is why some people still feel it on a full dose — volume and pressure are unchanged, so the material still moves where it should not.
It is also why the pattern changes below tend to matter most for exactly the people who assume they are beyond help because the tablets did not work.
Whether to continue, adjust or stop acid suppression is a question for your physician, and long-term use is worth reviewing with them periodically rather than by default.
What the first appointment covers
- When symptoms happen, relative to meals and to lying down — the timing usually identifies the mechanism
- Meal size, spacing, and the gap before bed, measured rather than estimated
- What you have already removed, and whether it was ever tested
- Weight, where relevant, and a realistic approach to it
- Alcohol, caffeine and smoking
- A structured challenge for one or two suspected triggers, rather than a blanket list
When to see a doctor instead
Difficulty or pain on swallowing, food sticking, unintentional weight loss, vomiting blood, black stools, or anaemia need investigation rather than dietary advice, and promptly.
Long-standing reflux carries a risk of changes to the oesophageal lining (Barrett's oesophagus), which is monitored medically. If reflux has been part of your life for years, that is a conversation to have with a physician regardless of how well the symptoms are currently controlled.
Chest pain is not something to attribute to reflux on your own. Cardiac causes are excluded by a doctor, not by a meal plan.
Booking, and what it costs
Two routes, and which one is cheaper depends entirely on your plan rather than on which sounds better.
Through insurance. Medical nutrition therapy is a covered benefit on many plans, sometimes with no copay at all. Booking runs through Fay Nutrition, which checks your benefits before the first appointment so you know the number in advance rather than six weeks later.
Self-pay. A flat $140 per session through CognitiveMind — no benefits check, no prior authorization, no denial arriving after the fact. If your coverage is thin, absent, or has a deductible you will not meet this year, this is often the more predictable of the two.

Common questions
What foods should I avoid with GERD?
Fewer than the standard lists suggest. Coffee, chocolate, citrus, tomato, mint and fatty or spicy food appear on every reflux list, but the evidence that removing them helps is thinner than the lists imply, and triggers are strikingly individual. A better approach is to test one or two suspects deliberately, for a defined period, then reintroduce and watch. Most people end up limiting one or two things rather than nine.
Why do I still have reflux on a PPI?
Because acid suppression changes how acidic the reflux is, not whether it happens. The volume and the pressure are unchanged, so material still moves into the oesophagus. That is exactly why meal size, the gap before lying down, weight where relevant, and alcohol tend to matter most for people who assumed they were beyond help because the tablets did not fix it. Whether to continue or adjust the medication is a question for your physician.
How long should I wait after eating before lying down?
About three hours, consistently. It is the single change most people have never properly tried, and one of the most effective. Raising the head of the bed helps too, but it needs to be the bed frame rather than extra pillows, which bend you at the waist and can make reflux worse.
Will losing weight help my reflux?
If you have excess weight to lose, this has the strongest evidence of any dietary intervention in reflux. The mechanism is mechanical rather than mysterious: abdominal weight increases the pressure pushing against a valve that is trying to stay closed. Modest losses often produce disproportionate relief, which is why it is worth addressing before a long list of foods.
When is reflux something more serious?
Difficulty or pain when swallowing, food sticking, unintentional weight loss, vomiting blood, black stools or anaemia all need prompt medical investigation rather than dietary advice. Long-standing reflux also carries a risk of changes to the oesophageal lining, called Barrett's oesophagus, which is monitored medically. And chest pain should never be attributed to reflux without a doctor excluding cardiac causes.
