The nopal cactus, commonly known as the prickly pear reveals itself as an important source of minerals in the diets of people in Mexico and the rest of Latin America, thanks to analyses with atomic spectroscopy and other techniques. Researchers in Mexico have tested the plant at different stages of its maturation to demonstrate its nutritional profile.

Prickly pear species grow in most environments around the globe and have for many years been investigated as putative health supplements and as a source of nutrition, beyond their native habitats. Previous research has also looked at the effects of a diet containing nopal and found it to have has no effect on blood glucose, total cholesterol or high-density lipoprotein (HDL) cholesterol levels. However, it has been shown in laboratory tests to reduce low-density lipoprotein (LDL) cholesterol but only if eaten raw in relatively large amounts.

Other medicinal effects have also been reported. For instance, there is some evidence from other limited studies that the plant can affect blood glucose levels. There are hopes that should some extract of the plant may provide a novel lead for blood glucose control and potentially in diabetes treatment.

Avanzada, in the Departament of Nanotechnology at the Univeridad nacional Autonoma de Mexico, in Queretaro and colleagues studies samples of fresh nopal pads (Opuntia ficus indica, Redonda variety) , known as cladodes and nopal powder. They carried out various analytical tests at different stages of the plant's development, with nopal powder being produced by dry vacuuming at low temperature (40 Celsius).

The researchers determined levels of the toxic natural product, calcium oxalate, using X-ray diffraction and scanning electron microscopy (SEM) and quantified using atomic absorption spectroscopy. They found that calcium content increases during maturation while phosphorus and oxalate content falls. Soluble fibre levels also decrease from about a quarter to about 15% while insoluble fibre increases from less than a third to just over 40%.

There is a significant body of research into the constituents of Opuntia species, but much of this is at least two decades old. Current studies using modern techniques will help bring the nutritional and constitutional status of the prickly pear up to date.

Calcium through the kidneys suddenly increased in a short period of time, easy to form stones. So kidney stone patients, bedside should not drink high-calcium milk. (7) Do not overdose of cod liver oil-rich cod liver oil and vitamin D, a membrane of intestinal calcium absorption functions, suddenly increased the urinary excretion of calcium and phosphorus is bound to have precipitation, easy to form stones.n

Will not affect sexual function, generally speaking stones at 0.5 mm, no clinical symptoms, can not handle. Male sexual dysfunction and a variety of factors : If excessive exertion and psychological tensions, sexual dysfunction and so may lead, asymptomatic stones generally not affected Kidney stones diet 1 calcium oxalate calculus : to low calcium and oxalate diet. Food and milk and dairy products, soybean products, meat, animal offal (liver, heart, kidney, intestines, etc.), chocolate, tea, Seasame butter, egg yolks and mushrooms, spinach, sealable plastic bag, carrots, cocoa, celery, potatoes, etc.. In recent years cellulose found in the food can reduce the formation of urine, such as wheat bran food of wheat bran bread, rice husks have the same effect, and the recurrent urinary calculi effective calcium, vitamin B1, vitamin B6, lack of urinary oxalate number should increase vitamin-rich food such as cereals, dried fruit hard fruits. 2 calcium phosphate stones and magnesium ammonium phosphate stone : its low calcium diet with the same calcium oxalate stones. Phosphorus in food, to food and meat, fish and soup bones. 3 urinary calculi : should limit the intake of protein, the total daily protein intake should be 48 to 80 grams (0.8 to 1.0 g / kg / day) between. General leafy vegetables Jin each containing about 10 grams of protein, lean meat every category of about 50 grams of protein-containing 10 grams of cereal each containing Jin 35-60 grams of protein. To increase the fresh vegetables and fruit eat. Fruits and vegetables contain vitamin B1 and vitamin C, their in vivo metabolism of the final product is alkaline, alkaline uric acid in the urine within easy solution, it is beneficial to the treatment. Conventional treatment : once every 1-2 daily diet cool (HEALTH fruit, juice and lettuce), at least once a week cool diet.
