Effect of magnesium on phosphorus and calcium metabolism.
Calcium is a nutrient needed for strong bones, but your body cannot absorb it properly without Relationship of Serum Magnesium and Vitamin D Levels in a . For those not familiar with the complementary relationship between calcium and magnesium, the first and foremost fact that should be known is. Background. Mean magnesium intake in the US population does not differ from that in East Asian populations with traditionally low risks of colorectal cancer and .
What foods contain calcium? Calcium and disease Cancer A growing body of research has emerged raising concern about the link between dairy products and prostate cancer 1. The results of a systematic review and meta-analysis showed that high intakes of dairy, total milk, whole milk, low-fat milk, cheese, and dairy calcium was associated with a modest, but significant risk of prostate cancer 5.
This study did not find an association between plant-based milks or calcium supplements and the risk for prostate cancer 5. The association between dairy products, calcium supplementation, and colorectal cancer is not as clear, with some studies showing a benefit of dairy products or calcium supplementationwith others failing to find any association 9, Cardiovascular Disease Earlier studies have raised concerns that calcium supplements increase the risk of cardiovascular disease.
However, the results of a recent systematic review and meta analysis concluded that calcium intakes that did not exceed the upper limit for calcium, from either supplements or food, were not associated with an increased risk of cardiovascular disease Regardless, it may be wise to err on the side of caution, aiming for an intake that meets, but doe not exceed the RDA for calcium, until more research becomes available.
Magnesium What is magnesium and why do I need it? Magnesium is involved in more than reactions in the body, assisting in the release of energy from fat and carbohydrates, helping with DNA production, supporting nerve impulses, muscle contractions, as well as normal heart rhythms, facilitating cellular communication, and providing structure to bones and body tissues Estimates suggest that almost half of the US population is not meeting recommended requirements for magnesium, with the lowest levels of intake being found among the elderly Older adults are believed to be disproportionately affected due to low dietary intake of magnesium, reduced absorption, and increased urinary losses Overt magnesium deficiency is rare in developed countries, but is more commonly seen in specific conditions, including gastrointestinal disorders, renal disease, diabetes, and alcoholism When magnesium deficiency has been experimentally induced in humans, tremor, muscle spasms, loss of appetite, nausea, vomiting, and personality changes occurred In addition, magnesium deficiency also disrupts calcium balance, which can exaggerate vitamin D deficiency How much magnesium do I need each day?
Requirements for adults and children were set following balance studies that aimed to match intake to losses Nutrients that interact with magnesium Like calcium, many nutrients and food components can interfere with magnesium. In addition, magnesium status is impacted by too little or too much protein, warranting intake around the RDA How much magnesium is too much? The upper limit for magnesium applies to supplements only and has been set at mg per day for individuals aged 9 years and older Since magnesium is a natural laxative, intakes above this amount can cause diarrhea Individuals with renal disease are more likely to experience magnesium toxicity and should avoid supplementation, unless approved by their medical doctor What foods contain magnesium?
Plant-based foods, especially seeds, nuts, beans, and wheat bran, are the best sources of magnesium.Endocrinology - Calcium and Phosphate Regulation
Magnesium and disease Magnesium deficiency has been implicated in several chronic diseases, including hypertension, type 2 diabetes, and cardiovascular disease. The results of a meta-analysis showed that supplemental magnesium helped reduce blood pressure in individuals with hypertension In addition, magnesium, along with dietary fibre and potassium, is a key component of the DASH diet; a dietary pattern shown to effectively reduce blood pressure What is the ideal ratio of calcium to magnesium?
The relationship between calcium and magnesium is complex, interdependent, and not fully understood. Studies have shown that high intakes of calcium may interfere with magnesium status by reducing intestinal absorption and increasing urinary losses Additionally, magnesium deficiency is known to induce calcium deficiency in experimental conditions A ratio of 2: Until more research is published on the ideal ratio of calcium to magnesium, the best approach is to meet minimum targets for magnesium, while ensuring a calcium intake at, but not above, the RDA.

The quality of our soil has deteriorated as well, due to the use of fertilizers that contain large amounts of potassium a magnesium antagonist. This results in foods lower in magnesium than ever before. When you look at how calcium is absorbed these problems become easier to understand, and often can be controlled through diet.
Magnesium is needed for calcium absorption. Without enough magnesium, calcium can collect in the soft tissues and cause one type of arthritis.
Not only does calcium collect in the soft tissues of arthritics, it is poorly, if at all, absorbed into their blood and bones. But taking more calcium is not the answer; it only amplifies the problem. In fact, excessive calcium intake and insufficient magnesium can contribute to both of these diseases. Magnesium taken in proper dosages can solve the problem of calcium deficiency. When calcium is elevated in the blood it stimulates the secretion of a hormone called calcitonin and suppresses the secretion of the parathyroid hormone PTH.
These hormones regulate the levels of calcium in our bones and soft tissues and are, therefore, directly related to both osteoporosis and arthritis. PTH draws calcium out of the bones and deposits it in the soft tissues, while calcitonin increases calcium in our bones and keeps it from being absorbed in our soft tissues. Sufficient amounts of magnesium determine this delicate and important balance.
Because magnesium suppresses PTH and stimulates calcitonin it helps put calcium into our bones, preventing osteoporosis, and helps remove it from our soft tissues eliminating some forms of arthritis. A magnesium deficiency will prevent this chemical action from taking place in our bodies, and no amount of calcium can correct it.
While magnesium helps our body absorb and retain calcium, too much calcium prevents magnesium from being absorbed.
So taking large amounts of calcium without adequate magnesium may either create malabsorption or a magnesium deficiency. Whichever occurs, only magnesium can break the cycle.
Magnesium is Key to Calcium Uptake
In experiments reported in "International Clinical Nutrition Review," a number of volunteers on a low-magnesium diet were given both calcium and vitamin D supplements. AU the subjects were magnesium-depleted and although they had been given adequate supplements, all but one became deficient in calcium.
When they were given calcium intravenously, the level of calcium in their blood rose, but only for the duration of the intravenous feeding.
As soon as the intravenous calcium was stopped, the levels calcium in the blood dropped.

However, when magnesium was given, their magnesium levels rose and stabilized rapidly, and calcium levels also rose within a few days - although no additional calcium had been taken. In fact, he has found that when calcium intake is decreased, it is utilized better than when it is high.
Abraham is one of many doctors and biochemists who advocate taking more magnesium to correct calcium-deficiency diseases.

A magnesium-rich diet can be helpful both for arthritis and to help prevent osteoporosis. This consists of nuts, whole grains such as brown rice, millet, buckwheat kashawhole wheat, triticate, and rye, and legumes including lentils, split peas, and a varieties of beans.
A whole grain cereal or bread in the morning, a cup of bean soup at lunch, a snack of a few nuts, and serving of brown rice, millet, or buckwheat with dinner should help increase magnesium when a deficiency is suspected. At the same time, refined sugar and alcohol should be reduced, and eliminated when possible to prevent magnesium from being excreted in large quantities in the urine. You may also want to re-evaluate the amount of dairy in your diet. If it has been disproportionately high, reduce or temporarily eliminate it until some of your symptoms are alleviated, or until you feel more of a balance has been achieved through the inclusion of whole grains and legumes.
Oriental and Indian diets contain little or no dairy, yet arthritis and osteoporosis are not major health problems in these cultures.
