The DASH diet, short for Dietary Approaches to Stop Hypertension, is a dietary plan aimed at preventing and managing high blood pressure (hypertension). Developed by the National Institutes of Health (NIH) in the 1990s, the DASH diet emphasizes nutrient-rich foods while minimizing the intake of sodium, added sugars, and saturated fats. Its primary goal is to promote heart health by encouraging a balanced intake of potassium, calcium, and magnesium, which are crucial for maintaining healthy blood pressure levels.
The Core Principle of the DASH Diet
The DASH diet is based on a straightforward principle: consume more whole plant based foods and fewer processed foods. It prioritizes foods that are naturally high in nutrients, full of fiber and low in unhealthy fats. This diet recommends:- Fruits and Vegetables: Aim for 4-5 servings of each daily.
- Whole Grains: Incorporate 6-8 servings per day.
- Lean Proteins: Include beans, poultry, fish, and nuts, while limiting or eliminating red meat and full-fat dairy.
- Healthy Fats: Choose unsaturated fats from sources like olive oil and avocados.
- Low Sodium: Reduce sodium intake to less than 2,300 mg per day, with a target of 1,500 mg for even more benefits.
