Proteins are large bio-molecules that consist of one or more long chains of amino acid residues. They perform an array of functions that are germane to growth and development of organisms [see]. Proteins supply macro-nutrients needed for building of bones, muscles, cartilage, skin, and blood in an organism. Eating protein-rich food guarantees the supply of amino acids for building up the body. Although proteins are important in human diets, and should be consumed in adequate quantity, it is important to be mindful of the type of protein one consumes. Broadly, protein-rich foods can either be from animal or plant origins. Proteins from these two sources basically differ in their amino acid contents; animal proteins contain all essential amino acids and are known as complete protein while plant proteins lack at least one essential amino acid and are regarded as incomplete [see]. Although, almost all natural proteins are inherently good, certain sources of protein are observed to promote healthy body conditions than others [see].
One important, but often less popular, source of protein from animal origin is snail. Snails belong to the class of animal called Gastropods, in the phylum mollusca. There are either terrestrial or aquatic snails. Some snails are shelled while some are not. Although not snails are edible, the notable edible snails include the giant land snail Achatina achatina, Helix aspersa, Helix pomatia, Cepaea nemoralis, Cepaea hortensis, Achatina fulica, Helix aperta, Otala punctate e.tc. They are prepared for food as escargot. Snails are known to be nutritious- they contain high amount of protein in addition to their low calorie content. Also, snails are rich in nutrients like selenium, omega-3, magnesium, vitamins and iron [see]. The rich iron content makes them very relevant in formation of blood [see]. In fact, malnutrition and iron deficiency, especially in pregnant women and children, can be tackled by eating snails. It has low fats and amino acids such as arginine and lysine. Considering the high level of cholesterol in eggs and red meat, the snail meat provides a healthier alternative protein [see]. Its slime and serum are good for skin maintenance, while its lectin can boost body’s immunity against cancer [see]. While deliberate efforts to rear and make snail meat a common delicacy can guarantee a healthier society, it is unfortunate that meat from this health-friendly gastropods is not commonly found on the table of many people for consumption.
