Seaweed, Pegan Diet, and Fermented Foods: Top Nutrition Trends 2026

A Sea of Seaweed

Seaweed has moved far beyond its role in sushi and is becoming a mainstream ingredient in many forms: snacks, chips, and crackers. This dark-green marine vegetable is a low-calorie source of protein and fiber and often supplies more trace minerals and vitamins than terrestrial greens like kale. Seaweed provides vitamin C, iodine and a range of compounds with antiviral, antibacterial and anti-inflammatory properties, making it a nutrient-dense option to incorporate into a balanced diet.

Paleo + Vegan = Pegan

The “pegan” approach blends elements of paleo and vegan diets. It emphasizes roughly 75 percent vegetables and fruits, while the remaining 25 percent can include organic animal proteins, whole grains, lentils and healthy fats such as nuts, coconut and avocados. Advocates of this pattern suggest it may help lower cholesterol and reduce the risk of type 2 diabetes by prioritizing whole, minimally processed foods, a variety of plant-based produce and moderate, high-quality proteins.

ferment2 Reasons to Eat Fermented Food

  1. Fermented foods contain live cultures—naturally occurring probiotics—that support a healthy gut microbiome. Examples include yogurt, sauerkraut, tempeh, miso and kimchi, as well as fermented beverages like kombucha. These beneficial bacteria help maintain digestive balance, support nutrient absorption and can contribute to overall gut health.
  2. Emerging research links a healthy gut microbiome to improved mood and reduced anxiety. Probiotics from fermented foods may decrease gut inflammation and irritation, which can positively influence brain function and emotional well-being. While more studies are needed, incorporating fermented foods into a varied diet may support both digestive health and mental wellness.
