According to the Food and Agriculture Organization (FAO), aflatoxins contaminate up to one-quarter of the world's food crops annually, posing a significant risk to global food safety. The principal aflatoxins are a group of highly toxic mycotoxins produced by certain fungi, primarily from the genus Aspergillus.

Over 2,000 species of fungi are considered safe for human consumption, but a small percentage of saprophytic fungi are lethally poisonous. Determining whether you can eat saprophytic fungi involves more than just their food source; it requires expert identification, careful preparation, and an understanding of look-alikes.

Did you know that fungi cannot produce their own food like plants do? Instead, the mode of nutrition in fungi is heterotrophic, meaning they rely on external organic sources for survival, acting as nature's ultimate recyclers or complex mutualists.

While honey fungus is famous for forming some of the largest living organisms on Earth, its reputation as an edible mushroom is met with necessary caution. So, is honey fungus good for you, or does its parasitic nature make it a forest food to be avoided?

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?

Scientific research on yeast, a type of fungus, has shown that it actually requires vitamin B1 for growth and metabolism, a fact that directly contradicts the notion that vitamin B1 is antifungal.

In a recent breakthrough, Swiss scientists developed a 'living battery' using fungi and nanotechnology, capable of producing eco-friendly electricity from sugars. This innovative development raises a crucial question: what is the fungus for energy, and how can these versatile microorganisms provide sustainable power for our future needs?

Ergosterol, a sterol analogous to cholesterol in animals, is an essential component found almost exclusively in the cell membranes of fungi, including yeasts and molds. This unique lipid is crucial for maintaining membrane integrity, fluidity, and proper function, making it an excellent target for antifungal medications. Beyond its biological role in fungi, ergosterol is also significant to humans as a dietary provitamin D2 source.

Although generally considered safe for most, some individuals should strictly avoid lion mane due to potential adverse effects and drug interactions. This medicinal mushroom, also known as *Hericium erinaceus*, has several active compounds that can influence the body's physiological processes. Understanding these risks is crucial for safe consumption.

Over 1 billion people worldwide are estimated to have vitamin D deficiency, making dietary sources and supplements critical for public health. Ergosterol is called pro-vitamin D because it serves as a biological precursor to vitamin D2, a process that relies on ultraviolet (UV) radiation. This sterol, found in fungi and yeast, is chemically converted into the active vitamin form, offering a unique pathway for humans to acquire this vital nutrient.
