Salty snacks that earn their keep
Ten high-sodium snacks arranged from zero effort to ten minutes at the counter, each delivering roughly a gram of sodium from a different source. Practical options for hitting the daily salt target between meals.
Meals are often the last thing anyone with POTS or post-viral fatigue wants to plan, and yet the daily salt target (8 to 10 g, roughly 3 to 4 g of sodium) does not take a day off. This is where snacks matter. A well-chosen handful between proper meals can deliver a gram of sodium, a useful amount of protein or fibre, and almost no effort. The ten below are arranged loosely from “open a jar” to “ten minutes at the counter”, and between them draw salt from a dozen different sources so nothing becomes monotonous. Sodium figures are from typical UK supermarket labels and should be read as approximate. For the physiology behind why sodium matters and what the guidelines recommend, see salt in POTS: evidence and everyday practice; for a broader look at salt alongside fluid and compression, see the salt, water, compression, and electrolytes evidence review.
1. Olives and almonds
A small ramekin of 50 g of pitted Kalamata or Nocellara olives with 25 g of salted almonds alongside. Mediterranean fats, a bit of vitamin E, and enough chew to count as a proper pause.
About 1.6 g salt, 640 mg sodium.
2. Cottage cheese with tomato, black pepper and seeded crackers
150 g of full-fat cottage cheese tipped onto a plate, topped with a sliced tomato, cracked black pepper, a few basil leaves if you have them, and 3 or 4 seeded rye crackers (Ryvita Multigrain or similar) on the side. Roughly 18 g of protein for very little work.
About 1.8 g salt, 720 mg sodium.
3. Tinned sardines in brine on sourdough
One tin of sardines in brine (about 90 g drained, brine is important, oil-packed are barely salty) tipped onto a toasted slice of sourdough with a squeeze of lemon, black pepper, and a scatter of parsley or chives. Omega-3s, vitamin D, calcium from the soft bones.
About 2.1 g salt, 840 mg sodium.
4. Miso-glazed boiled eggs
Hard-boil 2 eggs, peel, and sit them for an hour (or up to two days) in a small tub with 1 heaped tablespoon of white miso thinned with 1 teaspoon of rice vinegar and 1 teaspoon of water. The miso clings to the white and seasons the yolk. Good cold from the fridge.
About 2.3 g salt, 920 mg sodium for the pair.
5. Feta, cucumber and mint in a bowl
60 g of feta, crumbled, tossed with half a cucumber cut into chunks, a handful of torn mint, a tablespoon of olive oil and a squeeze of lemon. Hydrating, cold, ready in three minutes.
About 2.2 g salt, 880 mg sodium.
6. Hummus, olives and oatcakes
3 tablespoons of shop-bought hummus (most supermarket own-brand is around 0.9 g salt per 100 g) with 6 pitted green olives and 4 rough oatcakes (Nairn’s or similar). Beta-glucan fibre from the oats, a bit of iron, no cooking.
About 1.7 g salt, 680 mg sodium.
7. Anchovy toast
2 anchovy fillets in oil draped over a slice of buttered toast, half a sliced hard-boiled egg on top, black pepper, a tiny drizzle of the anchovy oil. Absurdly salty for the effort, surprisingly balanced with the egg.
About 2.4 g salt, 960 mg sodium.
8. Salted edamame
150 g of frozen edamame in their pods, boiled for 4 minutes or microwaved from frozen, drained, and tossed with ½ teaspoon of flaky sea salt and a pinch of chilli flakes. Pop them out of the pods with your teeth. Around 12 g of plant protein and a reasonable amount of folate.
About 2.5 g salt, 1000 mg sodium (most stays on the pods; actual intake is closer to 1.5 g, but enough reaches the bean to make it worthwhile).
9. Smoked salmon and cream cheese on rye
40 g of smoked salmon folded over 1 heaped tablespoon of full-fat cream cheese on a slice of dark rye, capers, lemon, dill if you have it, black pepper. Roughly 12 g of protein.
About 2.2 g salt, 880 mg sodium.
10. Cheese, apple and Marmite on toast
Thin layer of Marmite on a slice of buttered wholemeal toast, 30 g of grated mature Cheddar melted under the grill for two minutes, eaten with a sliced crisp apple alongside. The apple cuts through the salt and adds a little fibre.
About 2.6 g salt, 1040 mg sodium.
A few things worth keeping in mind. Pair every snack with a glass of water, because salt without fluid does not expand plasma volume and may just make you thirsty; the salt in POTS article covers the physiology of why sodium and water work as a pair. Spread snacks through the day rather than front-loading them, since gradual intake holds in the vascular compartment better than a single large dose. And rotate; the same olive-and-feta routine every afternoon gets dull fast and tends to narrow the rest of your diet in unhelpful ways. If a particular snack leaves you with swollen ankles, persistent headache, or a home blood pressure reading above 140/90, ease off and check in with your GP; the appointment preparation guide covers how to frame that conversation.
