Food · Pairing
What do I pair this with?
Protein first, then the carbohydrate. Type what you are about to eat.

The proteins
96 shownProtein figures are approximate, from standard food-composition values and typical UK pack sizes. The back of the pack always wins. Precision is not the point. Knowing that hummus is about 4 g and a tin of tuna is about 25 g is.
Practical Protein figures are food-composition values, not clinical claims. The safety notes attached to individual items are avoid-list claims and are sourced there. The reference values, and the reasoning behind the groupings, are in Protein pairing; every ⚠ note below is an avoid-list claim.
Nausea mode: cold, bland, low odour
20Odour rating: 🟢 essentially none · 🟡 mild · 🔴 do not open this on a bad day.
Neutral, cold, spoonable, no chewing effort.
Drinkable when nothing chewable is possible. Use a straw.
Bland to the point of boring, which is the feature.
Skip mature and blue cheeses: sharper aroma.
Sealed until the moment of eating. That is a bigger deal than it sounds.
The sulphur is in the yolk. Two whites is about 7 g with almost no smell.
Near-odourless. Genuinely one of the best nausea proteins, and almost nobody suggests it.
Steam it from frozen the night before, chill it, eat it cold.
Ambient, sealed, crunchy, salty.
Salt often lands better than sweet in first-trimester sickness.
Low protein for the calories, but it goes down when nothing else will, and it is paired.
Very low effort.
⚠ See the protein-powder note at the bottom of this page, and run it past the midwife.
Read the evidence · Absolutely avoid: the aisle cardThe peanut smell is strong for some and comforting for others. Test it once.
Fine cold. Reheating it is what makes it unbearable.
Fine for some, an instant trigger for others.
Excellent protein, catastrophic timing. Save tuna, sardines and mackerel for a good day.
A microwave aerosolises the smell into a small room in ten seconds.
The highest-odour form of the highest-value protein. Boiled and cold instead.
Two-minute assemblies

11The single best default. Read the label: “Greek-style” is often only 4-6 g of protein, while genuine strained Greek yoghurt is 10 g per 100 g. This one distinction is worth more than most of this page.
Thicker and more sour. Some people tolerate the tang better when nauseated, some much worse.
Cold, bland, no cooking. Underrated.
Very low in fat, so add a nut butter if it does not hold you.
Hard cheese is fine even unpasteurised.
Handbag-proof, and fine out of the fridge for a few hours. The reference handbag unit is one of these with an oatcake, about 9 g.
Fine unpasteurised.
Fine. No rind, no mould.
The laziest possible pairing for cereal, but only if the pour is generous.
⚠ Unpasteurised kefir is out.

4British Lion eggs are fine runny, but hard-boiled is what travels.
The workhorse.
Sold at both Waitrose and M&S. Zero preparation and no smell until the shell is opened. Keep chilled and eat within the use-by.
The nausea trick: the sulphurous smell is mostly in the yolk.
Fish
6⚠ Maximum four medium cans a week.
Read the evidence · Absolutely avoid: the aisle cardAlso a real source of calcium and iron.
⚠ Counts toward the two oily-fish portions a week.

⚠ Counts toward the oily-fish cap.
Read the evidence · Absolutely avoid: the aisle cardCooked shellfish is fine. Keep chilled and eat within the use-by.
Cooked and sterilised, so fine.
Meat
6Cold cooked sliced meat is fine under UK guidance if it is properly chilled and in date.
Cooked, not raw-cured. A completely different rule from prosciutto.
Also a useful hit of haem iron. Fully cooked, not rare.
Handbag staple. Very salty, so not an every-day habit.
As with biltong. Check for added sugar.
⚠ NHS says be careful. The risk is toxoplasma. Cook until steaming hot and it is fine.
Read the evidence · Absolutely avoid: the aisle cardPlants, nuts and seeds
14Two minutes in the microwave from frozen, or eat it cold. Very low odour.
Nuts are actively encouraged now. The old avoidance advice was withdrawn.
Also a decent source of non-haem iron and zinc.
Lower in protein than it feels.
The fastest carbohydrate rescue in existence.
Reality check: hummus is a weak protein source. It feels like a protein but it is mostly fat and carbohydrate. Fine as the fat pairing; do not count on it as the protein.
Ambient and shelf-stable, good for the bedside box and the handbag.
Rinse them and eat them cold with olive oil and lemon.
Beans on toast is already a paired carbohydrate. It is a genuinely good default.
Can be eaten cold, straight from the pack, with soy sauce.
Check the label. Plain coconut and oat yoghurts are close to zero protein.
Vegetarian and vegan
10⚠ Not gluten-free.
Read the evidence · Absolutely avoid: the aisle cardSoya, not oat or almond. Those are close to zero protein.

Bedside and overnight
7Does not spoil, does not smell, and leaves no crumbs on the pillow.
Ambient, savoury, crunchy.
The carbohydrate half. Never on their own.
Drinkable protein for when chewing is impossible, and it needs no fridge.
Survives a few hours out of the fridge.
The pre-standing water bolus. Plain water, not squash and not an isotonic drink: the reflex works through low osmolarity.
The classic eat-before-you-sit-up item.
Rules for a nausea day
- Nothing that needs a hob or an oven. Heat releases aroma compounds, which is literally why hot food smells more.
- Nothing opened over a sink. Warm sink smells plus a freshly opened protein is the classic trigger stack.
- Get someone else to open the packet, plate it and leave the room. Delegating the opening matters as much as delegating the cooking.
- Eat near a window, or with a fan on. Moving air is free.
- Cold or fridge temperature. Never steaming.
- Drinkable protein beats chewable protein when the texture is the problem: cold milk, kefir, a plain milkshake, unflavoured protein in cold water.
- If a food makes her sick once, retire it for two weeks. Conditioned aversion is real and it will burn through the list fast.

Making it effortless
The evidence for pairing is good. Pairing fails for one reason: at the moment of hunger, a nauseated, exhausted person eats whatever requires zero decisions.
- Pre-pair at the point of purchase, not the point of eating. Buy the crackers and the mini cheeses in the same trip and keep them in the same box. If they live in different cupboards, the pairing loses.
- Decant on a good day. One twenty-minute session: boil six eggs, portion nuts into bags, split a big yoghurt tub into pots, fill the bedside box. That session buys a week.
- Three fixed locations, always stocked: bedside, handbag, and the desk or sofa side. If protein only lives in the kitchen, a kitchen-avoidance day is a zero-protein day.
- Buy the pre-prepared version without guilt. Ready-boiled eggs, ready-shelled edamame, chilled protein pots, pre-cooked chicken. The premium is small and the difference in what actually gets eaten is enormous.
- Never store the protein behind a cooking step. If eating it needs a pan, then on a bad day it does not exist.
- The one-hand rule. If it cannot be opened one-handed while lying down, it does not belong in the bedside box.
- Delegate the restock, not just the cooking. The failure mode is always “the box was empty at 3am”.
Practical Logistics, not evidence. The claim these are built on, that pairing works but fails at the moment of hunger, is in Protein pairing.
Traps and things that do not work
- “Greek-style” is not Greek yoghurt. The most common single error. Greek-style can be about 4 g of protein a pot; strained Greek yoghurt is about 17 g. Read the back.
- Hummus as the protein. About 4 g per two tablespoons. It is a fine fat pairing. It is not a protein anchor.
- Smoothies and juice. A fruit smoothie is a naked carbohydrate in a glass, delivered fast. Add yoghurt, milk, silken tofu or nut butter, or do not drink it on an empty stomach.
- Front-of-pack “high protein”. The claim is based on the percentage of energy from protein, so a low-calorie product can carry it with very few actual grams. Use the grams-per-pack figure, not the flash.
- Protein bars. Many are 8-10 g of protein with 20 g of sugar and enough sugar alcohols to worsen bloating. Some are excellent. It is entirely a back-of-pack question.
- Collagen powder. Marketed as protein, but it is an incomplete protein with no tryptophan and no evidence behind it for glucose control. Not a substitute for whey, dairy or soya.
- Sugary rescue as a strategy. A fast carbohydrate rescues an acute dip, but simple carbohydrate is implicated in causing the reactive-hypoglycaemia cycle in the first place. Rescue with it; do not build on it.
- Cutting carbohydrate instead of pairing it. Not the goal, and actively counterproductive when bland carbohydrate is often the only tolerated food. The intervention is pairing, not restriction.
- Chasing a daily protein total. The UK increment in pregnancy is +6 g a day. Distribution across the day is the whole game.

Protein powder: the honest position
Plain whey or pea protein is just concentrated food protein, and premeal whey has the best trial evidence of anything here for flattening a glucose peak . But protein powders in the UK are sold as food supplements rather than medicines, so their composition is not regulated the way a drug is, and many carry added botanicals, high-dose vitamins, sweeteners or caffeine.
Practical position: an unflavoured, single-ingredient whey or pea isolate from a mainstream brand, checked for added herbs, caffeine and vitamin A, is a reasonable tool, and it should be run past the midwife rather than assumed.

If she is eating vegan
These are nutrient issues rather than food-safety issues, and they belong in the supplement conversation with the midwife. Vitamin B12: no reliable plant source, so a supplement is non-negotiable. Iron: non-haem iron absorbs poorly, so pair it with vitamin C and keep tea and coffee away from the meal. Iodine: dairy and white fish are the main UK sources. Omega-3 DHA: algal oil rather than fish oil, and note that cod liver oil is off the list in pregnancy because of its retinol content.
