Developed in the USA, Dash is the acronym for Dietary Approaches to Stop Hypertension, and has proved so healthy that it’s been recommended for everybody, not just those with hypertension.
As with the Mediterranean diet, the Dash diet concentrates on replacing high protein, saturated and animal fats, and refined sugars with more simple fare.
The do's:
The bulk of the diet consists of:
- Lentils and a variety of beans
- Fresh vegetables
- Fresh fruit
The don'ts:
Only eat small portions of:
- Low-fat dairy products
- Meat, poultry, fish
- Nuts
The reasons for the do's and don'ts:
- Vegetables and fruit contain significant amounts of potassium. Potassium appears to replace and eliminate excess sodium from the body's tissues, enabling dilation of the blood vessels and lowering of the blood pressure. Some studies indicate that higher levels of potassium in the blood may inhibit the formation of free radicals and the formation of blood clots, both of which play a role in the development of atherosclerosis.
- A maximum of two portions of meat, poultry or fish, and three portions of low-fat or fat-free dairy food per week to lower fat consumption (to counteract obesity and elevated blood fat levels) and protein consumption (and thereby hidden fats, as well as preventing possible kidney failure due to high protein intake).
The following table outlines the major food groups, and the number and sizes of servings you need:
Food group | Daily servings | Serving sizes | Examples/Notes | Significance of each Food group to the Dash Diet pattern |
