This article will analyze mushroom protein, plant protein, and animal protein from three aspects: nutritional components, health effects, and environmental protection and safety.
Nutritional Components
Protein Content: The protein content in mushrooms ranges from 15% to 30% (protein accounts for dry matter). Although it is lower than that in animal proteins (such as 3% - 7% in dairy products and 22% in meat) and some plant proteins (such as 36% - 40% in legumes and 15% - 30% in nuts), it has unique advantages.
Protein Allergenicity: Mushroom protein has low allergenicity. In contrast, animal proteins like those in dairy products, eggs, fish and seafood, and meats have relatively high allergenicity, and plant proteins in soybeans, nuts, wheat, peanuts, and corn also have certain allergenicity.
Energy: Mushrooms have relatively low energy, approximately 22 - 37 kcal/100g. Animal proteins have higher energy (such as 365 - 350 kcal/100g in meat and 80 - 200 kcal/100g in fish), and plant proteins also have relatively higher energy (such as 330 - 400 kcal/100g in legumes and 350 - 390 kcal/100g in grains).
Nutrients: Mushrooms are free of cholesterol and low in saturated fat. They possess a complete set of essential amino acids with high bioavailability. They contain trace elements such as potassium, phosphorus, magnesium, iron, and zinc, and are rich in vitamin B complex, vitamin D, vitamin C, and other antioxidant vitamins. Animal proteins contain higher cholesterol and saturated fat, have a relatively complete set of essential amino acids with high bioavailability, and are rich in heme iron and high calcium, but have lower contents of vitamin B12 and folic acid. Plant proteins are free of cholesterol and low in saturated fat, but have incomplete amino acids and lower bioavailability. They are rich in vitamin C and folic acid, and have more dietary fiber.
Health Effects
Mushrooms: They can enhance immunity, have antioxidant and anti-inflammatory effects, and are beneficial for cardiovascular health, blood sugar regulation, intestinal health, and anti-cancer potential.
Animal Proteins: They are conducive to muscle and bone health, promoting muscle synthesis, but there is a risk of reducing bone density.
Plant Proteins: They are beneficial for cardiovascular and blood lipid control, help promote gastrointestinal digestion, and can reduce the incidence and mortality of cardiovascular diseases.
Environmental Protection and Safety
Mushrooms: They have a relatively small impact on the environment. They use agricultural waste as a culture medium and have a low carbon footprint. They do not involve artificial hormones, pesticides, fertilizers, antibiotics, etc.
Animal Proteins: They involve issues such as greenhouse gas emissions, deforestation/grassland degradation, and water resource pollution.
Plant Proteins: They have problems such as soil degradation, excessive water pumping/eutrophication, and greenhouse gas emissions.
