DASH is an eating pattern developed to help lower blood pressure. It emphasises vegetables, fruit, pulses, whole grains and lower-fat dairy or alternatives, while reducing excess salt and heavily processed foods.
It does not require a separate health-food shop. Frozen vegetables, beans, oats, potatoes, yoghurt and smaller portions of meat all fit. Read labels on sauces, stock and ready meals, where salt can accumulate without tasting obviously salty.
Continue prescribed blood-pressure medicine and monitoring. If you have kidney disease or take medicines that affect potassium or fluid balance, ask your GP or pharmacist before making a major change or using potassium-based salt substitutes.

If you are pregnant, take regular medicine or live with a long-term condition, speak to your GP, nurse, pharmacist or a registered dietitian before making a major change to the way you eat.
The pattern on a normal shop
The DASH pattern emphasises vegetables, fruit, pulses, whole grains, nuts, seeds, fish and lower-fat dairy where suitable. It also limits heavily salted foods and frequent processed meat.
On an ordinary budget, frozen vegetables, oats, beans, potatoes and own-brand wholemeal bread can do much of the work. Meat can become a smaller part of a dish rather than its entire centre.
Potassium from food, not pills
Bananas, potatoes, beans, yoghurt and spinach provide potassium, which is one reason they feature in DASH-style eating. Food is the safest source for most people.
Do not start potassium supplements or salt substitutes without advice if you have kidney disease or take heart, blood-pressure or water tablets. In those situations, both too little and too much potassium can matter.
Much of the salt in UK diets comes from bread, sauces, snacks, processed meat and ready meals rather than the pinch added at the table. Compare labels, rinse tinned pulses and choose lower-salt options when practical.
Garlic, lemon, vinegar, pepper, cumin and herbs bring flavour while the palate adjusts. The aim is a lower-salt pattern across the week, not a joyless plate.
A DASH-friendly week in practice
A practical week might include porridge with fruit, bean chilli with brown rice, baked potatoes with yoghurt and beans, fish with vegetables, and a lentil pasta sauce. Repeat useful ingredients rather than buying a different health product for each day.
Choose portions and dairy alternatives that suit your needs, and use personal advice if you have diabetes, kidney disease or another condition affecting the plan.
Breakfast: porridge with fruit, or eggs on wholemeal toast.
Lunch: lentil soup and bread, or jacket potato with beans.
Dinner: tray-bake chicken with frozen Mediterranean veg and new potatoes.
Snacks: fruit, unsalted nuts in small portions, yoghurt.
Meal Pilot can help compare vegetable-rich recipes and their salt content before shopping. Planning even two or three suitable dinners can reduce reliance on very salty convenience food when the day runs late.
Batch a bean chilli or tomato sauce and vary the sides so the second meal feels different without starting another shop.
