Meet the microbiome—without hype

• Oats Grains
  Grains like oats carry beta-glucan, a gel-forming fibre, plus other fibres microbes can ferment. Grains add a different mix again from legumes or fruit.
• Lentils Legumes
  Legumes bring fermentable fibres and resistant starch — material many gut microbes can use — alongside plant protein.
• Blueberries Fruit
  Fruit adds soluble fibre together with polyphenols, colourful plant compounds that grains and legumes do not supply in the same way.
• Spinach Vegetables
  Leafy vegetables contribute their own fibres and a wide range of micronutrients. Leaves, stems and roots each bring something a little different.
• Almonds Nuts And Seeds
  Nuts and seeds pair fibre with unsaturated fats and minerals, so they widen the mix in a different direction again.
• Herbs Herbs And Spices
  Even small amounts of herbs and spices add more kinds of plant compounds. Small additions still count toward variety.

You explored more plant families, and each contributes something a little different. Variety — not any single food — is the general idea. Repeating a tile is fine; there is nothing to win.
