What Is the DASH Diet?

The DASH diet is an evidence-based eating plan designed to lower high blood pressure (hypertension).

It focuses on:

• Eating more fruits and vegetables
• Choosing whole grains over refined grains
• Prioritizing lean proteins
• Using healthy fats instead of saturated fats
• Reducing sodium intake

Research shows the DASH diet can lower blood pressure within just a few weeks when followed consistently.

Building a Hawaiʻi-Style DASH Plate

1/2 Your Plate: Vegetables

Choose a variety of colorful vegetables such as:

• Watercress
• Choi sum
• Lūʻau leaves
• Broccoli
• Cabbage
• Limu (seaweed)

Frozen vegetables are a budget-friendly option and just as nutritious when unseasoned.

1/4 Your Plate: Whole Grains or Smart Starches

Instead of large scoops of white rice, try:

• Hapa rice (half brown, half white)
• Brown rice
• ʻUala (sweet potato)
• ʻUlu (breadfruit)
• Poi (moderate portion)

These options provide fiber, which helps manage blood pressure and blood sugar.

1/4 Your Plate: Lean Protein

Choose:

• Fresh fish (ahi, mahi-mahi, ono)
• Skinless chicken
• Tofu
• Beans and lentils
• Lean cuts of pork

Limit processed meats like Spam, Portuguese sausage, and corned beef.

What to Limit on the DASH Diet

Sodium

Aim for 1,500–2,300 mg of sodium per day depending on your provider’s recommendation.

Common high-sodium local foods include:

• Shoyu
• Seasoning packets
• Processed meats
• Canned soups

Rinsing canned goods can remove up to 40% of the sodium.

Saturated Fat

Reduce:

• Pork belly and fatty cuts of meat
• Butter and lard
• Full-fat coconut milk
• Fried foods

Replace with olive oil, canola oil, avocado oil, and lean proteins.

Added Sugar

Limit:

• Soda and fruit punch
• Sweetened iced tea
• Heavy desserts

Choose whole tropical fruits like papaya, mango, and pineapple instead.

Budget-Friendly DASH in Hawaiʻi

Healthy eating in Hawaiʻi can feel expensive. Focus on:

• Buying rice and oats in bulk
• Choosing dried beans and lentils
• Buying frozen vegetables
• Purchasing seasonal fruit
• Cooking at home more often

Why the DASH Diet Works

The DASH diet increases potassium, magnesium, fiber, and healthy fats — nutrients that help relax blood vessels and lower blood pressure.

At the same time, it reduces sodium and saturated fat, which strain the heart.

The result: lower blood pressure, improved cholesterol, and reduced risk of heart attack and stroke.

‍

Start Small

You do not need to change everything at once.

Start with one step this week:

• Mix white rice with brown rice.
• Add one extra vegetable to dinner.
• Switch from fried to grilled.
• Use low-sodium shoyu.

Small changes, done consistently, lead to long-term heart protection.
