Insects as food or edible insects are insect species used for human consumption. Over 2 billion people are estimated to eat insects on a daily basis. Globally, more than 2,000 insect species are considered edible, though far fewer are discussed for industrialized mass production and regionally authorized for use in food. Many insects are highly nutritious, though nutritional content depends on species and other factors such as diet and age. Insects offer a wide variety of flavors and are commonly consumed whole or pulverized for use in dishes and processed food products such as burger patties, pasta, or snacks. Like other foods, there can be risks associated with consuming insects, such as allergic reactions. As commercial interest in insects as food grows, countries are introducing new regulatory frameworks to oversee their production, processing, marketing, and consumption. With over 2000 identified edible insects, there are many options for consumption. Insects may provide a sustainable option for protein sources containing 13-77% protein by dry weight. Some insects may also be used as a fat source boasting up to 67.25% lipids by dry weight. Insects can provide omega-6 and omega-3, iron , and zinc. Besides nutrients, the energy obtained by eating insects can be similar to other food sources like beef and chicken depending on what kind of insect is eaten. There are also environmental benefits from using insects as a food source: Insects require significantly less feed, can be used in feed, and release fewer CO2 emissions than conventional animal food sources. They can be used to address the issue of depleted agricultural lands as they don't need much space to be reared as compared to livestock. Additionally, food waste is a significant issue with 1/3 of food being wasted globally; Since insects can eat food waste, and they require less feed, they are a good option to address food waste.
