Calcium mineral intake and lactose intolerance – The Nation

Mrs Nancy Qibtia Tahir and Dr Ali Raza Awan – Calcium is a key nutrient in the human body.
More than 99% that is 1 .
2-1.
4kg of calcium is stored in bones and tooth.
Calcium level is taken care of in the body with the help of three systems: kidneys, intestine and bones.
A daily dietary intake of 1000mg of calcium would potentially result in 800mg available for tissue nutrient requirements plus 200mg for maintaining serum ranges.
Extra intestinal calcium is definitely processed through kidneys and taken off body through urinary excretion.
Calcium is involved in vascular contraction, vasodilation, muscle functions, nerve tranny, intracellular signaling and hormonal secretions.
The minimum calcium necessity is 700mg/day.
Predominant sources of calcium in the diet include dairy products (milk, yogurt, cheese) and commercially made food cereals, orange juice plus breads.
Calcium metabolism has close association between: phosphorous, Vitamin D and protein.
Milk and several dairy products contain lactose: a disaccharide that is hydrolyzed into glucose and galactose by lactase enzyme found in the brush border of human intestinal wall.

Lactose intolerance is a disorder caused by incomplete hydrolysis of lactose due to lactase deficiency.
It may occur as being a primary disorder, secondary to other intestinal diseases or it may be congenital within rare cases.
Generally lactose restricted diet is followed within suspected individuals, and avoiding dairy & milk containing products can result in dietary calcium intake that is beneath recommended levels: 1g/day for adults plus adolescents.
The perceived major health risk associated with lactose intolerance consists of osteoporosis, fractures due to weak our bones and colonic carcinoma.
Principal lactose intolerance could be treated by chemical replacement with lactase, probiotics and in case of secondary ailments by antibiotics.
On the other hand it could become managed by using pre-hydrolyzed lactose milk, consuming fermented dairy products, ingesting whole milk with other foods, taking small amounts associated with milk in snacks so that digestive tract could adapt the lactose present in daily food.
Diagnosis for this disorder includes: blood sugar levels, hydrogen breathing test, stool pH-test and with creation of latest molecular biology techniques; DNA based tests have been developed.
The Single Nucleotide Polymorphism (SNP) in the genes especially LCT-gene could be diagnosed at pre-natal stage.
It is recommended that the families with lactic intolerance history should have the genetic guidance before deciding their marriages.
Genetic counseling is a new concept in Pakistan and this arena of genetics should be commonly introduced designed for masses at local levels, so the genetic mutations prevailing in many family members could be diagnosed and proper treatments could be provided.
