The Kind Days guide: eating well when your body needs a little extra
What the HSE, the NHS and patient charities say about food, fluids and salt, turned into simple low energy habits, with every source linked.
The short answer
Eating well when your body needs a little extra usually means small, regular meals, plenty of fluid, extra salt only if your doctor agrees, and meals that take little energy to make. There is no single proven diet for any condition, so the best plan is the one built around your own symptoms, with a GP or registered dietitian.
This guide gathers what public health services (the HSE in Ireland, the NHS in the UK) and the main patient charities say about food and drink, and turns it into practical, low effort habits. It is general information, not medical advice.
POTS, EDS and MCAS often appear together, which is why advice for one has to fit around the others. Each one has its own chapter below. Read the one that is yours, and skip the rest.
The chapters
- Chapter one: eating with POTS
- Chapter two: eating with EDS
- Chapter three: eating with MCAS
- Chapter four: eating on low energy days
- Chapter five: a gentle day of eating
- Chapter six: when to talk to a professional
Chapter one: eating with POTS
POTS (postural tachycardia syndrome) is an abnormal rise in heart rate when you stand up, with symptoms like dizziness, fainting and tiredness. The NHS lists fluids, salt and meal size among the things that can help. NHS: PoTS
| Habit | Why it can help | Source |
|---|---|---|
| Drink more fluid through the day | More fluid supports blood volume, which can ease dizziness on standing. | NHS, POTS UK |
| Extra salt, only on medical advice | Salt helps the body hold on to fluid. It is not safe for everyone. | NHS, POTS UK |
| Small, frequent meals | Large meals draw blood to the gut and can make symptoms worse afterwards. | NHS, POTS UK |
| Go easy on alcohol | Alcohol widens blood vessels and can worsen symptoms. | NHS |
| Watch how caffeine affects you | Some people find it helps, others find it raises heart rate. Track it. | POTS UK |
Salt advice for POTS is the opposite of the general advice for adults, which is no more than 6g of salt a day. That is exactly why extra salt should be agreed with your doctor first. NHS: salt in your diet
A quick way to drink more is to have a large glass of water before you get up, then keep a bottle within reach.
Chapter two: eating with EDS
EDS (Ehlers-Danlos syndromes) are inherited conditions that affect connective tissue. Many people with hypermobile EDS also have gut symptoms and fatigue, which shape what and how they can eat. NHS: Ehlers-Danlos syndromes, The Ehlers-Danlos Society
No. There is no diet proven to treat EDS. The Ehlers-Danlos Society describes gut problems as common in people with EDS and recommends managing them with your healthcare team. The Ehlers-Danlos Society
What usually makes the biggest difference is practical: meals that are easy on the gut for you, food that is easy to prepare, and enough protein and fluid across the day.
Cutting out whole food groups without support can leave gaps in your nutrition. If you are thinking about it, ask for a referral to a registered dietitian.
Chapter three: eating with MCAS
MCAS (mast cell activation syndrome) causes allergy-like reactions. Some people react to particular foods or drinks, but triggers are individual. Mast Cell Action
Only with care. Food triggers in MCAS are individual, and a strict diet that is not tailored to you can be restrictive without helping. Mast Cell Action has patient information on diet and triggers. Mast Cell Action
| Step | What to do |
|---|---|
| 1. Notice | Log what you eat and any reaction for two to four weeks. Nomeriu tracking takes seconds. |
| 2. Look for patterns | Only treat a food as a trigger if the reaction repeats. |
| 3. Get support | Take your log to your GP, specialist or a registered dietitian before removing foods. |
| 4. Reintroduce | Anything you remove should be tested again later, with support, so your diet stays as broad as possible. |
If you ever have signs of a severe allergic reaction, such as swelling of the throat or trouble breathing, call 999 or 112 straight away.
Chapter four: eating on low energy days
Fatigue is common with POTS, EDS and MCAS, and on any day when energy is low. The aim is food that needs as few steps, and as little standing, as possible.
| Situation | What to try |
|---|---|
| Standing makes you dizzy | Prep sitting down: a stool at the counter, chopping at the table. |
| Good days and bad days | Batch cook on good days and freeze single portions for bad ones. |
| No energy to cook at all | Keep a list of no cook meals: yoghurt with oats, wraps, soup from a carton, cheese and crackers. |
| Hands or joints hurt | Buy pre chopped vegetables and use kitchen scissors instead of knives. |
| Forget to eat | Set a gentle reminder and keep easy snacks where you can see them. |
The Healthy Food Pyramid (HSE and safefood, Ireland) and the NHS Eatwell Guide (UK) are sensible bases for balance: fruit and vegetables, starchy foods, protein, some dairy or alternatives, and plenty of fluid. HSE: How to eat well, NHS: the Eatwell Guide
Chapter five: a gentle day of eating
This is one example, not a prescription. Adjust it to your own needs and any advice from your care team.
| Time | Food | Why |
|---|---|---|
| On waking | A large glass of water before getting up | Fluid before standing |
| Breakfast | Porridge or yoghurt with fruit | Easy, gentle, quick |
| Mid morning | A savoury snack, such as crackers and cheese | Keeps meals small |
| Lunch | Soup with bread, or a filled wrap | Little prep, can be batch cooked |
| Afternoon | Fruit, nuts or a smoothie | Steady energy |
| Dinner | A modest plate: protein, vegetables, rice or potatoes | Smaller portion, less pooling after eating |
Chapter six: when to talk to a professional
- Before you add extra salt, or if you have high blood pressure, heart or kidney problems.
- If you are losing weight without trying, or cannot keep food down.
- Before cutting out whole food groups.
- If you think a food causes reactions.
In the UK you can find a registered dietitian through the British Dietetic Association. BDA: find a dietitian
