Nutrition (approximate, per serving)

Based on 4 servings.

• Energy: ~350–400 kcal
• Protein: ~10–12 g per serving (4 servings); black beans provide most of the plant protein (~8 g per 100 g cooked)
• Carbohydrates: ~55–65 g (from beans, sweet potato, vegetables)
• Fat: ~8–10 g
• Fibre: ~14–18 g

Brain Health Notes

• Black beans are high in plant protein (~8 g per 100 g cooked) and provide fibre that feeds gut bacteria; fibre fermentation produces short-chain fatty acids (SCFAs) associated with gut health. Beans also supply folate and minerals.
• Sweet potato and carrots provide beta-carotene and fibre studied for antioxidant and vascular effects.
• Bell peppers and tomatoes contribute vitamin C and carotenoids.
• Extra virgin olive oil contributes monounsaturated fats and polyphenols associated with cardiovascular and brain health.
• Whole grains (quinoa or brown rice) provide slow-digesting carbohydrates and fibre.

Recipe nutrition

Figures are still calculated from USDA-based nutrient data on each food page (per 100 g). For this recipe we have not yet added ingredient weights, so the table adds one full “100 g” slice of each linked food, not the grams actually used (which would misrepresent small amounts like herbs, spices, or oil). When portion sizes are added for the recipe, the same panels are multiplied by the real amounts—so the maths can be precise for every ingredient.
