As heterotrophs, fungi are unable to produce their own food like plants, meaning they must absorb nutrients from other sources to survive. This fundamental difference from both plants and animals is key to understanding their role in ecosystems. So, what food do fungi need to survive?

Over 14,000 species of fungi exist as mushrooms in nature, but only around 200 are widely accepted as food, proving that while it is good to eat fungi, caution is essential. These edible species have been valued by humans for centuries for their unique flavors and significant nutritional contributions.

Over 1 billion people worldwide suffer from vitamin D deficiency, a condition that can be addressed by dietary intake and sun exposure. While most think of animal products for Vitamin D, many people, particularly vegans and vegetarians, rely on ergosterol, the provitamin that converts to vitamin D2 under ultraviolet (UV) light, as a key dietary source. Ergosterol is found predominantly in fungi and yeast, acting as a precursor to the crucial nutrient ergocalciferol.

Archaeological evidence from Spain's El Mirón Cave suggests human consumption of mushrooms may date back to the Paleolithic era, thousands of years ago. The multifaceted reasons why humans eat fungus extend far beyond basic sustenance, encompassing unique flavors, powerful nutrients, and traditional medicinal uses that continue to influence our diet today.

According to a 2023 report, mycelium is a nutritional powerhouse capable of providing complete protein and all essential amino acids, rivaling animal protein sources. But beyond being a sustainable meat alternative, is eating mycelium good for you, and what unique health benefits does this fungal root system offer?

Fungi, which include yeasts and molds, are heterotrophs, meaning they cannot produce their own food and must absorb nutrients from their environment. A central question in nutrition and health is: **Does fungus feed off carbs?** The answer is a clear yes, and understanding this relationship can be vital for managing conditions related to fungal overgrowth, such as candidiasis.
