- Vitamins and minerals are essential nutrients for carrying out various functions by the body
- Crying baby may shed vitamins in their tears, this could help to measure nutritional deficiencies
- Inexpensive, tear-based microfluidic devices or strips may help to improve access for nutritional assessment
Babies often cry easily and those tears may help to viably measure nutritional deficiencies, finds a study from the Michigan Technological University.
The research study was published in the journal Experimental Eye Research.
Maryam Khaksari, a research specialist at the Chemical Advanced Resolution Methods (ChARM) Laboratory at Michigan Tech, said, "Our goal was to seek the viability of establishing measurable units of tears for nutritional assessments."
The research team is trying to develop inexpensive, tear-based microfluidic devices or strips for improving access to test nutritional deficiencies.
Nutritional deficiencies in children can have lifelong effects. The research study tested the tear and blood samples of 15 infants who were four-months-old and their parents.
Water soluble vitamins which commonly include Vitamin B and C were present in infants. While, fat soluble vitamins that include Vitamin A, D, E and K were higher among parents.
There is usually a connection between parents and babies and correlation between Vitamin E and B. Formula-fed babies are exception, as they contain higher levels of vitamin B.
The research work may show promise for studying the trends in tear vitamin levels.
The author also says, "Since tears contain vitamins, they might have real potential to replace other clinical tests."
Nutritional Deficiencies in Children
Vitamins and Minerals are essential nutrients for children. Most of the children are deficient in the mineral iron and vitamin D.
Vitamins are essential for regulating body functions. Vegetables, cereals, fruits, nuts, dairy products, poultry, fish are all rich sources of vitamins.
Water-soluble vitamins include Vitamin B, C and Folic acid. These vitamins are dissolved in water and transported to other parts of the body.
Fat Soluble vitamins include vitamin A, D, E and K . These vitamins are absorbed and stored in the fat from where they are transported to the body.
Minerals are vital for a healthy living. Calcium, phosphorus, magnesium, iron are all some of the common minerals that are necessary to maintain the electrolyte balance in the body.
