Papua New Guinea Diet: Key to Better Gut Health and Lower Chronic Disease Risks

The Future of Gut Health: Trends Inspired by Papua New Guinea’s Diet

The Impact of Western Diets on Gut Health

Western diets, high in processed foods and low in fiber, have been linked to a rise in chronic diseases and obesity. These diets are wreaking havoc on our delicate gut microbiomes. In contrast, the traditional diet of the indigenous people in rural Papua New Guinea, rich in plant-based foods and high in fiber, offers a starkly different picture. Recent research shows that this diet could be the key to better gut health, slimmer waistlines, and lower chronic disease risks — all without the need for calorie restrictions.

How the NiMe Diet Revolutionizes Gut Health

The Non-Industrialized Microbiome Restore (NiMe) diet, developed by Jens Walter and his colleagues, mimics the eating patterns of Papua New Guinea’s rural populations. This diet is primarily plant-based, packed with fruits, vegetables, and legumes, and includes just one small serving of chicken, salmon, or pork daily. It excludes dairy, beef, and wheat, which are not part of the traditional diet in Papua New Guinea.

The NiMe diet focuses on providing a high-fiber intake, with a 2,500-calorie meal plan delivering a staggering 45 grams of dietary fiber per day. This far exceeds the 15 grams Americans get on average and even surpasses the 25 to 30 grams recommended for US adults.

Researchers tested the effectiveness of the NiMe diet by recruiting 30 healthy Canadians to follow the regimen for three weeks. The results were remarkable. The diet successfully restored aspects of the gut microbiome that play a key role in disease development, notably reducing pro-inflammatory bacteria. Additionally, the diet led to a 17% reduction in "bad" cholesterol, a nearly 7% drop in blood sugar, and a 14% decrease in C-reactive protein, a marker of inflammation and heart disease.

Study participants also experienced beneficial weight loss, despite not consuming fewer calories than usual. Such findings point to the profound effect of the diet on overall health.

The NiMe Diet: A Roadmap to Better Gut Health

Components of the NiMe Diet

The NiMe diet’s high fiber intake and plant-based focus not only corrects issues around gut microbiome health but also encourages weight loss and better cholesterol and sugar control.

What Does the Science Say?

Previous studies have shown that the Western diet’s effect on our gut microbiome could be leading to inflammation, fueling chronic disease growth, and aging cells. For example, research has found links between the western diet and colorectal cancer growth. Conversely, a diverse and healthy gut microbiome can help keep these issues at bay by promoting less inflammation and healthier cells.

This has led researchers to plan further studies to explore whether the NiMe diet can benefit people already dealing with chronic diseases like diabetes. The findings could also shape future dietary guidelines and inspire the development of new food products, ingredients, and therapeutics targeting the microbiome. Leading figures in microbiome research are optimistic about these results.

The gut microbiome is often called the “second brain.” It plays a crucial role in digestion, immunity, and even mental health.

## Additional Benefits

### Beyond Weight and Health:

Anissa Armet, a registered dietitian and postdoctoral fellow at the University of Alberta, who co-led the study, suggests that the NiMe diet might even lower the chances of developing certain cancers. A healthier gut microbiome could essentially rebalance gut flora to keep diseases in check.

In addition, Paul Ross, director of APC Microbiome Ireland, indicated that these discoveries are groundbreaking, as the results point to a promising future for more personalized dietary guidelines and food products. Epstein proposed a novel drug pathway based on microbiome recovery in situ.

### Bonus Recipe

If you’re curious about giving the NiMe diet a try, join Walter and his colleagues in experimenting with some of their delicious recipes. Their recipe book offers a bounty of delectable options. Try this **Yellow Pea Soup** to start your NiMe journey:

Ingredients

1 ¼ cups raw yellow split peas
2 tbsp olive oil
½ cup carrots, chopped
⅓ cup celery, chopped
3 tbsp onion, chopped
1 ½ tsp minced garlic
1 ⅓ cups canned cannellini beans, drained and rinsed
½ tsp low-sodium vegetable bouillon
½ tsp salt
¼ tsp black pepper
⅛ tsp (0.25 g) cayenne pepper

**Directions**

Rinse yellow split peas with cool running water, then add the rinsed peas to a large pot and cover with cold water, leaving about 2 inches of water above the peas.

1. Bring to a boil and cook on medium heat until softened. Drain any remaining water and set aside.
2. Simultaneously, heat olive oil in another large pot on medium-high. Once hot, add carrots, celery, and onion, then cook for about 10 minutes, stirring occasionally, until browned.
3. Add garlic and cook for another 1 to 2 minutes.
4. Stir in white beans, vegetable bouillon, salt, black pepper, cayenne, cooked yellow peas, and 600 mL of water.
5. Allow the mixture to simmer for about 30 minutes until vegetables are tender. For a smoother texture, blend the soup with an immersion blender. Serve warm.
