All animal foods.
Foods from animal sources provide complete proteins, which contain all essential amino acids needed by the body.
protein
Soy and animal proteins such as meat, dairy products (except butter) and eggs contain complete proteins.
In general, minerals in plant foods have a lower absorption rate compared to those in animal foods. This is primarily due to the presence of anti-nutrients, such as phytates and oxalates, in plant foods, which can hinder mineral absorption. Additionally, the bioavailability of certain minerals like iron and zinc is often higher in animal sources. As a result, while plant foods are valuable for their nutrients, they may not provide minerals as readily as animal sources do.
Vitamin K primarily comes from green leafy vegetables, such as kale, spinach, and broccoli, as well as from some fruits and fermented foods. It is produced by bacteria in the gut and is also found in animal products like meat and dairy. There are two main forms: K1 (phylloquinone) from plant sources and K2 (menaquinone) from animal sources and fermented foods. Including a variety of these foods in your diet can help ensure adequate intake of vitamin K.
The absorption of iron from plant foods differs from that from animal foods primarily due to the type of iron present. Animal sources contain heme iron, which is more readily absorbed by the body, while plant sources provide non-heme iron, which has lower bioavailability. Additionally, plant foods often contain compounds like phytates and polyphenols that can inhibit iron absorption. To enhance non-heme iron absorption, it is beneficial to consume vitamin C-rich foods alongside plant-based iron sources.
The type of vegetarianism known as veganism solely permits plant-based diets. All animal products—meat, seafood, dairy, eggs, and occasionally honey and gelatin—are avoided by vegans.
The two macronutrients are carbohydrates and protein.
The main sources of protein are animal based foods. For example meat, fish, poultry, milk, cheese and eggs.
Cartilage supplements come from such animal sources as cattle, sheep, sharks, and chickens, with cows and sharks being the predominant sources.
