What is the DASH diet?
Dietary Approaches to Stop Hypertension, an eating pattern developed and tested in controlled trials specifically to lower blood pressure. It emphasises vegetables, fruit, low-fat dairy, whole grains, legumes and nuts, while limiting sodium, red meat, and sugary food and drink.
How much does DASH lower blood pressure?
In the original trials, roughly 5–6 mmHg systolic on its own, and up to about 11 mmHg in people with hypertension when sodium was also reduced. That is a clinically meaningful effect, comparable to some medication, which is exactly why you should not adjust medication yourself.
How much salt is allowed on DASH?
The standard version targets around 2,300 mg sodium a day and the lower-sodium version around 1,500 mg. This plan sits under roughly 1,800 mg, between the two. For context, that is about three quarters of a teaspoon of salt in total, including everything already inside food.
Can I still eat bread and cheese?
Bread yes, if you choose a low-salt loaf. Ordinary bread is one of the largest sodium contributors in most diets purely because people eat a lot of it. Hard cheese is genuinely difficult on this plan; small amounts occasionally rather than daily.
Is DASH good for weight loss?
It was not designed for it, and this version at roughly 1,750 calories is around maintenance for many adults. It does tend to produce modest weight loss because it displaces processed food. If weight loss is a goal, set the calorie level deliberately using the calorie calculator.
Can I use a low-sodium salt substitute?
They work for many people, but most replace sodium with potassium chloride, which makes them a genuinely bad idea if you have kidney disease or take an ACE inhibitor, ARB or potassium-sparing diuretic. Check with your pharmacist first.
How is DASH different from the Mediterranean diet?
They overlap heavily. DASH is more prescriptive about daily servings, includes low-fat dairy explicitly, and targets sodium directly. The Mediterranean pattern uses more olive oil and fish and is less concerned with salt. Both have strong evidence; our Mediterranean plan is the alternative.
Why is low-fat dairy specified rather than full-fat?
Because that is what the trials used, and the trials are the reason DASH is recommended. There is reasonable debate about dairy fat generally, but if you want the pattern that was actually tested, low-fat is what it contained.
How long before I see a change?
Blood pressure responds faster than most people expect, often within two weeks. Use a home monitor at the same time each morning and look at the trend across a two weeks rather than reacting to single readings.
Can I get this built to my own targets?
Yes, the plan generator will build a week around your calorie needs and food preferences. If your clinician gave you a specific sodium target, use theirs rather than the one on this page.
