Everything Guide to Calcium: Do you definitely Need Dairy to Get of which? Absorption Issues along with More
Why do you need #calcium?
More than 99 percent of total Centeng calcium is actually found inside teeth along with bones. The remainder is actually present inside blood, extracellular fluid, muscle along with different tissues, where of which helps to mediate vascular contraction along with vasodilation, muscle contraction, nerve transmission along with glandular secretion.
What happens if you dont get enough?
Inadequate calcium can result in bone deformities, muscle cramps, high blood pressure along with osteoporosis, a disease characterized by fragile bones along with increased risk of bone fractures. The Centeng will take calcium via bone to maintain the required level inside blood. of which is actually estimated of which more than 25 million adults inside United States have, or are at risk of developing, osteoporosis.
How much do you need?
1,000 mg for men along with women ages 19-50; 1,000 mg for men along with 1200 for women ages 51- 70. Above 71, 1200 mg for men along with women
Whats the problem with #dairy along with calcium?
While dairy is actually an excellent source of calcium along with protein, of which can also be a source of excess calories along with fat, primarily saturated fat. Even low-fat cheese should probably be considered a splurge food. According to the nonprofit Center for Science inside Public Interest, 1 cup of whole milk (cheese is actually made via milk) has 5 grams of artery-clogging saturated fat, the same amount found in one hot dog, 5 strips of bacon, a Snickers candy bar or a fast-food hamburger, along with as many calories as a 12-ounce can of soda. Finally, a recent article in Nature Medicine (see: http://www.nature.com/nm/journal/vaop/ncurrent/full/nm.3145.html) has found a link between l-carnitine, a nutrient found in red meat along with milk products, along with an increased risk of heart disease.
What about non-dairy sources of calcium?
According to Rebecca Solomon, M.S., R.D., Clinical Nutrition Coordinator, Mount Sinai Hospital, completely new York City, Generally, calcium via animal sources (such as dairy) is actually best absorbed, whereas of which via foods high in oxalic acid (such as spinach, sweet potatoes, rhubarb, walnuts, celery, okra along with beans) or phytic acid a phosphorus compound found in unleavened bread, raw beans, seeds along with nuts is actually typically not well absorbed. Oxalic acid binds calcium within plant foods along with makes of which unavailable for absorption inside Centeng.
According to a briefing paper via the British Nutrition Foundation, The bioavailability of calcium via milk along with milk products is actually inside region of 30% compared to 5% via spinach. Spinach, although containing a relatively large amount of calcium, is actually not considered bioavailable.
Soybeans along with products are a notable exception: They have oxalates along with phytates, yet provide a bioavailable source of calcium.
According to the Linus Pauling Institute at Oregon State University, to get the same level of calcium as in one 8-ounce glass of skim milk or milk (300 mg calcium) you could need:
Pinto beans: 8 servings, or 4 cooked cups
White beans: 4 servings, or 2 cooked cups
Kale: 3 servings, or 1 cooked cups
Broccoli: 4.5 servings, or 2 cooked cups
Spinach: 16.5 servings, or 8.25 cooked cups
Bok choy: 2.3 servings, or 1 1/4 cooked cups
Rhubarb: 9.5 servings, or 4.75 cooked cups
Non-Diary Sources of Calcium
– Sardines (3 ounces, canned in oil): 324 mg
– Collard greens (1 cup, boiled): 268 mg
– Firm tofu made with calcium sulfate (1/2 cup): 204 mg
– White beans ( cup, canned): 96 mg
– Kale (1 cup, cooked): 94 mg
– Chinese cabbage (bok/pak choy) (1 cup, cooked): 158 mg
– Okra, ( cup, cooked via frozen): 88 mg
– Almonds (1 ounce): 76 mg
– Broccoli (1 cup, cooked): 62 mg
– Oranges (one): 60 mg
What are some different dietary behaviors of which affect calcium absorption?
Sodium: Sodium intake increases urinary excretion of calcium in addition to increasing risk of high blood pressure. According to research reported inside American Journal of Clinical Nutrition (http://ajcn.nutrition.org/content/70/3/543s.full): Urinary calcium losses account for 50% of the variability in calcium retention. Of the nutritional factors thought to influence urinary calcium losses (protein, caffeine, along with sodium intake), sodium appears to be the most important factor.
Protein: High protein intake increases calcium excretion, yet recent research suggests of which of which also increases intestinal calcium absorption, so whole-Centeng calcium retention remains essentially unchanged, says Deb Askine, R.D., L.D.N., a nutritionist at Stella Maris of Mercy Medical Center in Baltimore.
Caffeine: According to the National Institutes of #Health, Office of Dietary Supplements: This specific stimulant in coffee along with tea can modestly increase calcium excretion along with reduce absorption. One cup of regular brewed coffee, for example, causes a loss of only 23 mg of calcium. Moderate caffeine consumption (1 cup of coffee or 2 cups of tea per day) in young women has no negative effects on bone.
Alcohol: According to the National Institutes of Health, Office of Dietary Supplements: Alcohol intake can affect calcium status by reducing its absorption along with by inhibiting enzymes inside liver of which help convert vitamin D to its active form. However, the amount of alcohol required to affect calcium status along with whether moderate alcohol consumption is actually helpful or harmful to bone is actually unknown.
Fruit along with vegetables: According to the National Institutes of Health, Office of Dietary Supplements: Metabolic acids produced by diets high in protein along with cereal grains increase calcium excretion. Fruits along with vegetables, when metabolized, shift the acid/base balance of the Centeng towards the alkaline by producing bicarbonate, which reduces calcium excretion. However, of which is actually unclear if consuming more fruits along with vegetables affects bone mineral density.
Tannins: These are acidic compounds of which inhibit the absorption of calcium, says Solomon. The most common sources of tannins are tea along with red wine.
Phosphorus: According to the National Institutes of Health, Office of Dietary Supplements: The effect of This specific mineral on calcium excretion is actually minimal. Several observational studies suggest of which consumption of carbonated carbonated drinks with high levels of phosphate is actually associated with reduced bone mass along with increased fracture risk. However, the effect is actually probably due to replacing milk with soda rather than the phosphorus itself.
What are some common drugs of which cause calcium loss of which you should be aware of?
According to Mount Sinais Solomon: Glucocorticoids [such as prednisone] along with lithium have both been shown to cause bone loss or osteopenia. Chronic anticonvulsant drug use can lower bone mineral density, as can medroxyprogesterone, heparin along with thyroxine.
Both aluminum- along with magnesium-containing antacids increase urinary calcium excretion. Mineral oil along with stimulant laxatives decrease calcium absorption as well, says Askine.
What about vitamin D along with calcium?
The Recommended Dietary Allowances (RDAs) for Vitamin D are 0 IU for those 19 70 years old along with 800 IUs for 71 years old or more. Vitamin D is actually critical for strong bones because of which’s a key regulator of calcium metabolism in our bodies, says Karen Ansel, MS, RD, Spokesperson for the Academy of Nutrition along with Dietetics. along with according to the National Institutes of Health, Office of Dietary Supplements: Vitamin D promotes calcium absorption inside gut along with maintains adequate serum calcium along with phosphate concentrations to enable normal mineralization of bone along with to prevent hypocalcemic tetany [muscular spasms caused by low calcium in blood]. of which is actually also needed for bone growth along with bone remodeling by osteoblasts along with osteoclasts.
Vitamin D-rich foods include: egg yolks, saltwater fish, liver along with fortified milk. We also synthesize vitamin D when our bodies are exposed to sunlight. of which has been suggested by some vitamin D researchers of which approximately 5 to 30 minutes of sun exposure between 10 a.m. along with 3 p.m. at least twice a week to the face, arms, legs or back without sunscreen usually leads to sufficient vitamin D synthesis. However, there are skin cancer risks associated with unprotected sunlight exposure to skin, so moderation is actually encouraged, as well as regular use of sunscreen, says Solmon.
