One of the alarming challenges of modern time is accumulation of heavy metals in food chain. Heavy metals (lead, copper, mercury and arsenic etc) are making its way in our food chain through different routes. All our food and water come through pipes and synthetic plastic etc which affect hazardous on our health. These toxic material accumulates in the body and cause many negative affect on different functions of the body. The young are more prone to the toxic effects of heavy metals. Childhood exposure to some metals can result in learning difficulties, memory impairment, damage to the nervous system, and behavioural problems. At higher doses, heavy metals can cause irreversible brain damage. Children may receive higher doses of metals from food than adults, since they consume more food for their body weight than adults.
Severe effects include reduced growth and development, cancer, organ damage, nervous system damage, and in extreme cases, death. Exposure to some metals, such as mercury and lead, may also cause development of autoimmunity, in which a person’s immune system attacks its own cells. This can lead to joint diseases such as rheumatoid arthritis, and diseases of the kidneys, circulatory system, and nervous system.
This has led researchers to seek alternative solutions for decontaminating environmental sites and humans themselves. A number of environmental micro-organisms have long been known for their ability to bind metals, but less well appreciated are human gastrointestinal bacteria. Species such as Lactobacillus, have the ability to bind and detoxify some of these substances. This review examines the current understanding of detoxication mechanisms of lactobacilli and how, in the future, humans and animals might benefit from these organisms in removing environmental contamination of food.
In such complicated state of situation, the old food (camel milk) is realized as one of the best tool to combat. Not only a food but a gift of nature for natural health and beauty. Scientific studies revealed that fermented camel milk have wide range of lactic acid Bacteria which can be a good tool to minimize heavy metal consequences. Camel milk can be a great source of natural health for the infants in two way, i.e minimizing the risk of heavy metals and its closeness to human milk composition.
