Cooking Rice This Way Packs as Much Protein as 100g of Beef — U.S. Expert Praises the Method as Easy and Highly Nutritious

According to an American expert, simply adding a special ingredient when cooking rice can significantly boost its nutritional value — bringing multiple health benefits.

Rice: A Staple Food with Untapped Potential

Rice is a daily staple in many Vietnamese households, supplying essential nutrients like carbohydrates, B vitamins, and small amounts of plant-based protein to fuel the body.

Normally, rice is cooked using just one ingredient — rice itself. However, Dan Buettner, a U.S. researcher on longevity in global "Blue Zones" (regions with the world’s longest-living populations), suggests that adding legumes (beans) while cooking rice can dramatically increase its nutritional value and offer numerous health benefits.

Why Beans Are a Longevity Superfood

Buettner considers beans one of the most powerful "superfoods" for health and longevity. According to Well and Good, a U.S. health website, rice cooked with beans provides, on average:

• 3g of fiber

• 64% of the Daily Value (DV) for folate (vitamin B9)

• 28% DV for thiamine (vitamin B1)

• 30% DV for magnesium

• 38% DV for manganese

• 20% DV for iron

Buettner also highlights that rice cooked with beans can deliver the same amount of protein as about 100g of beef — but without the saturated fat found in red meat. This makes it especially heart-healthy.

Health Benefits of Cooking Rice with Beans

1. Supports Weight Loss and Fitness

Rice with beans is rich in protein and essential amino acids. Protein enhances metabolism, increases satiety, and reduces cravings — all of which support weight loss. Plus, the body burns more calories digesting protein than other macronutrients.

In fact, a review found that people who ate about 250g of beans daily for 6 weeks lost over 0.34kg more than those who didn’t.

Amino acids also help repair tissues, build muscle, and improve body composition.

2. Prevents Heart Disease and Type 2 Diabetes

Buettner notes that bean-rich rice dishes provide soluble fiber, which has been shown to reduce LDL "bad" cholesterol. Eating beans four times a week may reduce the risk of heart disease by 22%.

The high fiber content also helps regulate blood sugar, reducing the risk of type 2 diabetes.

3. Reduces Cancer Risk

Soluble fiber and resistant starch in rice with beans help feed beneficial gut bacteria. These bacteria produce short-chain fatty acids (like butyrate), which protect the gut lining, reduce inflammation, and lower the risk of colon cancer.

4. May Extend Lifespan

In Blue Zones like Costa Rica and Okinawa (Japan), incorporating beans into daily meals — including rice dishes — is a common practice among centenarians.

For example:

• Costa Ricans enjoy casado (a meal of rice, black beans, salad, and meat).

• Okinawans eat rice with red beans as part of their longevity diet.

Studies suggest that consuming just 20g of beans daily could extend life expectancy by up to 8 years.

In Conclusion:
Dan Buettner affirms that cooking rice with beans is simple, highly nutritious, and one of the best ways to support health, heart function, weight control, and longevity — all with minimal effort.
