Importance of Calcium


The average adult’s weight is made up of about two per cent calcium. Most of this is found in the skeleton and teeth; the rest is stored in the tissues or blood. Calcium is vital for healthy teeth and bones. It also plays a crucial role in other systems of the body, such as the health and functioning of nerves and muscle tissue. Good sources of calcium include dairy foods and calcium fortified products such as soymilk and breakfast cereals. People at different life stages need different amounts of calcium – young children, teenagers and older women all have greater than average requirements.According to the Australian Nutrition Survey, about 90 per cent of women and 70 per cent of children do not achieve the recommended dietary intake (RDI) for calcium. The role of calciumCalcium plays a role in:
Strengthening bones and teeth
Regulating muscle functioning, such as contraction and relaxation
Regulating heart functioning
Blood clotting
Transmission of nervous system messages
Enzyme function.Calcium and dairy foodAustralians receive most of their calcium from dairy foods. If milk is removed from the diet, it can lead to an inadequate intake of calcium. This is of particular concern for children and adolescents, who have high calcium needs. Calcium deficiency may lead to disorders like osteoporosis (a disease of both men and women in which bones become fragile and brittle later in life). Too little calcium can weaken bonesIf the body notices that not enough calcium is circulating in the blood, it will use hormones to reduce the amount put out by the kidneys in the urine. If not enough calcium is absorbed through the gastrointestinal tract, calcium will be taken from the bones. If your dietary intake of calcium is constantly low, your body will eventually remove so much calcium from the skeleton that your bones will become weak and brittle.Calcium needs vary throughout lifeThe recommended dietary intake of calcium is different for people of different ages and life stages:
Babies – from 7–12 months, babies are estimated to need 270mg per day if breastfed and 350mg per day if bottle fed. The calcium in infant formula may not be absorbed as efficiently as that found in breast milk. For children aged 1–3 years, the amount needed rises to 500mg per day.
Young children – skeletal tissue is constantly growing, so young children have high calcium needs. Children aged 4–8 years need around 700mg per day. This rises to 1,000mg per day for those aged 9–11 years.
Pre-teens and teenagers – puberty prompts a growth spurt. This group needs more calcium, with a recommended dietary intake of 1,300mg per day for both boys and girls between the ages of 12 and 18 years.
Peak bone mass years – from before the onset of puberty to around the mid-20s, the skeleton increases its bone mass. If the skeleton is strengthened with enough calcium during these years, diseases like osteoporosis in the later years are thought to be less likely. During mid-life, women and men both need around 1,000mg per day.
Pregnant women – although a developing baby needs a lot of calcium and this is taken from the mother’s bones, most women rapidly replace this bone loss once the baby has stopped breastfeeding. There is no additional dietary calcium requirement for pregnancy, except for the pregnant adolescent, who requires an additional 1,300mg per day of calcium to meet the requirements of both her own growth and the foetus.
Breastfeeding women – there is no increased requirement for calcium during breastfeeding, except for the breastfeeding adolescent, who needs an additional 1,300mg per day.
Elderly people – as we age, the skeleton loses calcium. Women lose more calcium from their bones in the five years around the age of menopause. However, both men and women lose bone mass as they grow older and need to ensure an adequate amount of calcium in their diet to offset these losses. While a diet high in calcium cannot reverse age-related bone loss, it can slow down the process. The recommended dietary intake for calcium is 1,300mg per day for women over the age of 50 years and men over the age of 70 years.
Non-Caucasian populations – populations with smaller frame sizes may need less calcium than Caucasian populations, who have larger frame sizes and higher intakes of animal foods, caffeine and salt.Good sources of calcium
Good dietary sources of calcium include:
Milk and milk products – milk, yoghurt, cheese and buttermilk. One cup of milk, a 200g tub of yoghurt or 200ml of calcium fortified soymilk provides around 300mg calcium. Calcium fortified milks can provide larger amounts of calcium in a smaller volume of milk – ranging from 280mg to 400mg per 200ml milk.
Leafy green vegetables – broccoli, collards, bok choy, Chinese cabbage and spinach. One cup of cooked spinach contains 100mg, although only five per cent of this may be absorbed. This is due to the high concentration of oxalate, a compound in spinach that reduces calcium absorption. By contrast, one cup of cooked broccoli contains about 45mg of calcium, but the absorption from broccoli is much higher at around 50–60 per cent.
Soy and tofu – tofu (depending on type) or tempeh and calcium fortified soy drinks.
Fish – sardines and salmon (with bones). Half a cup of canned salmon contains 402mg of calcium.
Nuts and seeds – brazil nuts, almonds and sesame seed paste (tahini). Fifteen almonds contain about 40mg of calcium.
Calcium fortified foods – including breakfast cereals, fruit juices and bread:
1 cup of calcium fortified breakfast cereal (40g) contains up to 200mg of calcium
½ cup of calcium fortified orange juice (100ml) contains up to 80mg of calcium
2 slices of bread (30g) provides 200mg of calcium.Calcium supplements It is much better to get calcium from foods (which also provide other nutrients) than from calcium supplements. If you have difficulty eating enough foods rich in calcium, you might consider a calcium supplement, especially if you are at risk of developing osteoporosis. It’s a good idea to discuss this with your health care professional. If you do take calcium supplements, make sure you don’t take more than the amount recommended on the bottle (usually 600–1,500mg per day). Too much calcium may cause gastrointestinal upsets, such as bloating and constipation. Lifestyle can affect bone strength Some of the factors that can reduce calcium in your bones and lower bone density (weaken bones) include:
High salt diet
More than six drinks per day of caffeine-containing drinks – for example coffee, cola and tea (although tea has less caffeine)
Excessive alcohol intake
Very low body weight
Very high intakes of fibre (more than 50g per day, from wheat bran)
Low levels of physical activity
Low levels of vitamin D – this may be an issue for people who are housebound or for women who cover their bodies completely when they are outside, as they do not get enough sunlight on their skin.Where to get help

The Fruit That Fights Wrinkles

You really can fight wrinkles from the inside out. And there's a fruit that can lead the charge. It's papaya. What makes papaya so perfect? Easy. Vitamin C. Papaya has loads of it, and getting lots of vitamin C may mean more youthful skin -- fewer wrinkles and less thinning and dryness. A recent study in women over 40 confirmed it.
The Mysteries of Vitamin C is a natural friend to skin. The nutrient is essential for making collagen, the protein fibers that give skin its strength and resiliency. And being a powerful antioxidant, C also disarms free radicals that would otherwise chip away and weaken collagen.

More Food for Your Face. A little extra vitamin C isn't all it takes to plump your complexion. Here are a few more food tips that can help keep your face fresh:

Munch on walnuts. In the vitamin C study, researchers also noted that diets rich in linoleic acid -- an essential fatty acid in walnuts -- meant moister, plumper skin.

Ease up on fats and refined carbs. Scientists found both were linked to aging skin.

Think whole grains. The magnesium and B vitamins you get from them help with the regeneration of skin cells.

Keep the fruits and veggies coming. To stay smooth and healthy, your skin needs a whole slew of antioxidant-rich produce.

Vitamin C May Help You Look Younger!

Can Eating Oranges Save Your Skin?
Vitamin C may help you look younger.

Searching for a way to look young for your age? Hit the produce aisle, suggests new research in the American Journal of Clinical Nutrition. Analyzing data from the National Health and Nutrition Examination Survey I (NHANES I)—a survey that asks people to quantify how often they eat various foods—researchers from Unilever linked consuming plenty of vitamin C-rich foods (such as oranges, tomatoes and strawberries) with youthful skin. "Our findings suggest that a higher intake of vitamin C from foods is associated with a lower risk of having wrinkled skin and age-related skin dryness in [middle-aged] women," says Maeve Cosgrove, Ph.D., who led the research.

Vitamin C’s youthful effects on skin may be due to its antioxidant properties, which help protect against ultraviolet rays, and its role in keeping skin firm via collagen synthesis, say the researchers.

Bottom line: Eating more vitamin-C rich foods, such as oranges, tomatoes, strawberries and broccoli, may be a secret to smoother skin.

OMEGA-3 FATTY ACIDS - For Soft, Smooth Skin

These supplements aren't just making headlines for preventing heart disease—dermatologists are recommending them to help heal dry skin and the rough, red, scaly patches of psoriasis and eczema. "Countless studies show that increasing the consumption of omega-3 oils improves these conditions," says Baumann. In one study published in the British Journal of Dermatology, volunteers with severe dermatitis taking high levels of omega-3s (6 g) saw a 30% decrease in symptoms. Psoriasis sufferers experienced similar results in other research.

It's easy to see why omega-3s are crucial to skin health: Besides being an integral part of the membranes that surround our skin cells, these essential fats—which must be obtained from diet or supplements because our bodies cannot make them—are a key component of the lubricating layer that keeps skin supple. They also aid in the production of hormones that improve skin texture and help combat the inflammatory damage wrought by free radicals—one of the causes of wrinkles and blotchiness. This is likely why sun-sensitive people may be significantly less prone to burning after omega-3 supplementation, according to one study.

Eating fish such as salmon, mackerel, and albacore tuna—good sources of omega-3s—twice a week and taking supplements are easy ways to increase your intake. For better skin, Baumann recommends taking 1,000 mg of omega-3 oils a day—about the same dosage recommended to keep your ticker in good shape.

Anti-aging Foods

Olive Oil

Four decades ago, researchers from the Seven Countries Study concluded that the monounsaturated fats in olive oil were largely responsible for the low rates of heart disease and cancer on the Greek island of Crete. Now we know that olive oil also contains polyphenols, powerful antioxidants that may help prevent age-related diseases.


In the 1970s, Soviet Georgia was rumored to have more centenarians per capita than any other country. Reports at the time claimed that the secret of their long lives was yogurt, a food ubiquitous in their diets. While the age-defying powers of yogurt never have been proved directly, yogurt is rich in calcium, which helps stave off osteoporosis and contains "good bacteria" that help maintain gut health and diminish the incidence of age-related intestinal illness.


Thirty years ago, researchers began to study why the native Inuits of Alaska were remarkably free of heart disease. The reason, scientists now think, is the extraordinary amount of fish they consume. Fish is an abundant source of omega-3 fats, which help prevent cholesterol buildup in arteries and protect against abnormal heart rhythms.


The Kuna people of the San Blas islands, off the coast of Panama, have a rate of heart disease that is nine times less than that of mainland Panamanians. The reason? The Kuna drink plenty of a beverage made with generous proportions of cocoa, which is unusually rich in flavanols that help preserve the healthy function of blood vessels. Maintaining youthful blood vessels lowers risk of high blood pressure, type 2 diabetes, kidney disease and dementia.


Studies of Seventh-Day Adventists (a religious denomination that emphasizes healthy living and a vegetarian diet) show that those who eat nuts gain, on average, an extra two and a half years. Nuts are rich sources of unsaturated fats, so they offer benefits similar to those associated with olive oil. They’re also concentrated sources of vitamins, minerals and other phytochemicals, including antioxidants.


In a landmark study published in 1999, researchers at Tufts University’s Jean Mayer Human Nutrition Research Center on Aging fed rats blueberry extract for a period of time that in "rat lives" is equivalent to 10 human years. These rats outperformed rats fed regular chow on tests of balance and coordination when they reached old age. Compounds in blueberries (and other berries) mitigate inflammation and oxidative damage, which are associated with age-related deficits in memory and motor function.

Look Younger Without Plastic Surgery

Strategies for shaving years off your appearance.

Wendy Bryant-Gow’s job is to worry about how other people look. “People always want to know how to look younger and slimmer,” says the Chapel Hill, N.C.-based image consultant.
But, lately, the newly divorced mother of two has started seeking her own fountain of youth—and her own advice.
“My 50th birthday is just around the corner, and my 30th high-school reunion is a few months away,” says Bryant-Gow. “I’ve been thrown back in the dating scene after all these years, and I’m surrounded by much younger women.”
Amid pressures to look younger in her personal and professional life, Bryant-Gow says that plastic surgery is not an option. Ever.
“I don’t want to do anything that’s invasive. I have two girls, so I don’t want to go under and not come out,” says Bryant-Gow. “I’m really just looking for a confidence boost.”
Most Americans seem to share this outlook; about nine out of 10 patients seeking to look younger want to do so without going under the knife, says Dr. David McDaniel, a dermatologist and the director of the Institute of Anti-Aging Research at East Virginia Medical School in Norfolk.
“People want to look like they’ve had plastic surgery without the surgery, the anesthesia, the down-time or the added expense,” McDaniel says. “The other thing is that people don’t want to look like they’ve had plastic surgery at all—they want to look like they’ve had rest or a vacation.”
Thankfully, shaving years off of your perceived age can be done without enlisting the help of a plastic surgeon (or taking a vacation). Here’s how:
Try Thermage
If you want cosmetic surgery without the surgery, consider Thermage. “In younger women, it can be comparable to a mini-face lift,” says McDaniel. “For older women, it’s an alternative to face-lift, but not quite an equivalent substitution.”
Thermage is actually a type of radiofrequency treatment that uses heat to tighten the skin and stimulate collagen production. The Food and Drug Administration first approved of the technology in 2001, but only recently and after a series of equipment upgrades has Thermage begun yielding marked skin-tightening results, says McDaniel.
The procedure is particularly attractive to people who do not want plastic surgery because it’s noninvasive and requires no recovery time. The drawbacks of Thermage, however, are that it’s still a rather pricey solution (depending on how many treatments you get, the entire process could costs you several thousand dollars), and clients usually have to wait three to six months for the skin’s collagen to grow before seeing results.
Still, says McDaniel: “It just fits with the more active lifestyle that people have today.”
Get a Massage
According to Joanna Czech, an esthetician who counts Uma Thurman, Kyra Sedgwick and Kate Winslet as regular clients, massage is not just for sore bodies—it’s also an important anti-aging tool.
“Massage can help keep your skin nice and firm; it is like a workout for your face muscles,” says Czech, who owns Sava Spa in Manhattan. The idea here is that kneading muscle tissue improves blood circulation, which in turn delivers nutrients and oxygen to the treated area. As a result, collagen fibers contained in the skin are more likely to retain their elasticity, she says.
Regular facials, which involve massage, are the ticket to keeping your face looking young, Czech says. The even better news is that massage works for the body, too. “It is simply the best way to prevent and minimize the appearance of cellulite. It makes the entire thigh and butt area look smoother,” she says.
Even the conditions of this solution don’t seem so bad. “If you want to see results, the most important thing, in my mind, is consistency,” says Czech. Ideally, this means receiving body massages and facials on a monthly basis. “We can reshape and improve women’s bodies until about the age of 60, so you can start this at any age,” Czech adds. (After 60, collagen fibers have difficulty retaining their full elasticity—at this point, they’re like worn out rubber bands.)
But seriously, it’s a massage! Why wait?
Eat Away the Years
What you eat can affect how old you look, according to Stephen Gullo, author of Thin Tastes Better and a nutrition psychologist based in Manhattan.
“Foods that increase inflammation and free radical production stimulate the aging process,” says Gullo. The good news is that this relationship also works in reverse: Eating foods that reduce inflammation and free radical production actually helps your body combat the march of time.
What, then, should an aging omnivore eat?
Dine on low-mercury—“white-colored”—seafood and lots of green and white non-starchy vegetables, Gullo says. “Eat these foods and avoid anything high in simple carbohydrates or fat—these are foods that can help accelerate the aging process,” he adds.
Gobbling down white bread and sugar can also leave you (and your face) looking quite bloated. This is because, for every gram of simple carbohydrate a person consumes, their body retains three grams of water, according to Gullo. Eliminate these foods from your diet, however, and in a few weeks, you’ll notice a big difference when you look in the mirror. “It’s the easiest way to look 15 years younger without a face-lift,” he says. Bye, bye bagels, hello sharp cheekbones!
Stay Young With Juvenon
Another key to looking young is feeling young. Cue a team of biochemists from the University of California, Berkley, who have created a pill that counters the development of aging in mice and rats. No, really.
The pill, called Juvenon, contains a cocktail of natural micronutrients that aid a cellular organelle called the mitochondria. Scientists often describe mitochondria as the “powerhouse” of cells because they are the source of energy for all cellular functions.
Research has shown that as we age, our mitochondria’s ability to produce energy diminishes. Consequently, this energy deficit eventually and adversely affects our mood, our central nervous system and every organ in our body—particularly our brains.
Like grease added to a squeaky wheel, Juvenon works by supplying our aged mitochondria with its missing micronutrients. As a result, the mitochondria are able to pump out as much energy as they did during their youth, according to Bruce Ames, the supplement’s principal creator and a professor of biochemistry at Berkeley.
So far, in preliminary experiments involving rats, the supplement has excelled. “All that I can say is that, if you are a rat, you have reason to be ecstatic,” says Ames. In these trials, Juvenon-fueled rats had higher IQ tests, less oxidative brain damage and a better immune system relative to the study’s controls. In addition, the rodents’ energy deficit almost entirely disappeared.
But what about humans in need of a pick-me-up pill?
Nearly 100,000 people have already purchased the supplement online, though Ames says that he and his colleagues are still investigating Juvenon’s impact on human aging. The biochemist also warns that the supplement’s purported effect on humans (that it improves cognition, boosts energy and lowers blood pressure, among other things) is still, by and large, rooted in anecdotal evidence. Yet, the scientist concedes: “So far, everything looks pretty good.”
Saving the Simplest Solution for Last
As you age, the color and texture of your hair changes and so does the color and texture of your skin. “We need to pay attention to these changes,” says stylist Bryant-Gow, who admits to practicing what she preaches. “A lot of times, our old high-school makeup palettes and 20-year-old hairstyles just won’t do.”
Older women can start to update their look by ditching their powders and foundation (which tend to accentuate facial wrinkles and fine lines) and invest in a light, tinted moisturizer, instead. Bryant-Gow also recommends enlisting professional help. “If you’re in a cosmetics store, it’s important to shop the faces behind the counter,” the stylist urges. “If you don’t like the way someone looks—if their own makeup seems too wild—keep walking.”
This approach also works when selecting a hair stylist. “How you style your hair needs to change as you age,” says Bryant-Gow. “Just make sure you’re consulting with the right people, and don’t be afraid to ask for their input.”
But what if your body—not just your face and hair—needs “updating”? Try body slimming undergarments, says Bryant-Gow. Creating a good foundation under your clothes will thin your silhouette and add polish to any outfit, the stylist says. “Plus, these undergarments hide everything—stomach bulges, sagging skin. Just everything.”
The simplest answer to anti-aging is, of course, to learn to accept yourself—lumpy thighs, age spots, wrinkles and all. There is no scarring or anesthesia involved, and you’re guaranteed to love the results.

Beauty and the Beasts

Cosmetics might not be as safe as we like to think.
By Maggie Koerth-Baker for MSN Health & Fitness

Roman women slowly poisoned themselves with generous slatherings of white lead foundation. Medieval Italians sensuously dilated their pupils—and blinded themselves—with an extract of belladonna. And the ladies of Queen Elizabeth’s court wore thick layers of red lip color made from toxic mercury compounds. All apparently were under the impression that their daily beauty regimen was 100 percent safe. Which begs the question: Are we similarly deluded today?

Cosmetic Conflict
Even if you don’t wear much makeup, chances are that you’re washing your hair with shampoo and conditioner, toning down your underarm stink with deodorant, and attempting to stave off old age with moisturizer. According to the Environmental Working Group (EWG), a watchdog organization that monitors the use of chemicals in everyday life, those simple actions add up fast. A survey the organization conducted in 2004 showed that American women use an average of 12 hygiene products each day. By the EWG’s count, that translates to more than 150 ingredients being absorbed through the skin, inhaled through the nose or inadvertently licked off the lips.

As far as the EWG is concerned, all this represents a massive risk to public health. “Essentially, we’re conducting a giant experiment,” says Jane Houlihan, the organization’s vice president for research. “People are being exposed to hundreds of chemicals. Every person is full of complex mixtures and the health consequences are completely unknown.” Particularly of concern to the EWG and other activist groups are two families of chemicals known as phthalates and parabens.
Phthalates are a common ingredient in things like hairsprays, nail polish and perfume, where they function as a plasticizer—keeping the mixtures flexible while also helping them remain sticky. Parabens are preservatives that keep fungus and bacteria at bay in a wide variety of cosmetics and hygiene products.

The EWG points out that research on rats has shown both chemical families to be carcinogens. A 2004 study published in the journal Reproductive Technology linked phthalates with reproductive anomalies, and a study published that same year in the Journal of Applied Toxicology detected parabens in breast cancer tissue. In fact, parabens and phthalates were among the chemicals banned by the European Union in 2003. A quick Web search will turn up a number of organizations that have extrapolated this research into warnings that makeup or deodorant are the cause behind breast cancer.

Naturally, this makes the cosmetics aisle seem pretty scary. But not all scientists agree that the danger is so great. The Food and Drug Administration officially classifies parabens and phthalates as safe, because the research has yet to prove a causal link between the chemicals and diseases in humans. As it turns out, rats, while convenient for research, don’t actually process chemicals the same way we do. So what’s deadly to them could easily be harmless in us. Other organizations—like the industry-run Cosmetics Ingredient Review board and the independent American Council on Science and Health—agree, pointing out that the amounts of phthalates and parabens used in cosmetics are far, far lower than even the amount needed to induce cancer in rats.
Pretty Is as Pretty Does
So, who’s right? The answer probably falls somewhere in between. “There’s a lot of people talking black and white, this is good or this is bad,” says Urvashi Rangan, an environmental health scientist who works with Consumer Reports magazine and its parent organization, the Consumers Union. “But a lot of the ingredients in cosmetics come down into a very gray zone.”
To Rangan, the fact that cosmetics use very low levels of chemicals doesn’t mean there’s zero risk. Instead, it means that we need more research to understand the effects of chronic, long-term exposure. On the other hand, chemicals aren’t inherently bad and Rangan thinks it’s inaccurate to say that using certain cosmetic products could be deadly.

“We don’t know all the reasons cancer happens,” she says. This means it’s impossible to identify a certain chemical as the precise—and sole—cause of a cancer. "To say these products are going to kill you is an overstatement. It's not likely that there's going to be a single reason behind why someone gets cancer."

Instead, Rangan says, the real problem lies in how we currently address the potential dangers associated with these chemicals. “Europe tends to operate on the precautionary principle and they tend not to make things legal until there’s a proof of safety,” she says. “Here, it’s the opposite. In order for the FDA to ban a chemical used in cosmetics it has to be proven harmful.”
And proving harm is tough. Usually, it requires thousands of people to develop a problem that can be linked definitively to a specific product or ingredient. Currently, the FDA has no authority to review cosmetics before they go to market and can only ban ingredients after problems arise. So, while most cosmetic products have been tested for short-term safety, their long-term effects are almost completely unknown. “There’s very little data to suggest safety or harm,” Rangan says. “There’s just a big question mark there.”

For now, whether or not you should keep using your favorite products depends a lot on how you use them and how much risk you’re comfortable with. For instance, occasionally using eyeliner with a questionable ingredient probably isn’t dangerous, but if you’re applying heavy amounts of a suspect lotion every day, you might want to consider taking steps to reduce your exposure.
One way to help gauge your risk is by looking up your brands on Skin Deep, the Environmental Working Group’s online database, which analyzes all the various risk factors associated with specific products.

Under Suspicion: 4 Ingredients to Keep an Eye On

What They Are: Preservatives that keep products bacteria-free.
Where You’ll Find Them: Cleanser, hand soap, moisturizers and toothpaste
Names They Go By: Methylparaben, propylparaben, and butylparaben.
What’s the Concern: Parabens can mimic natural hormones, including estrogen. Disruption of sex hormones increases the risk of certain cancers.

What They Are: Plasticizers that increase flexibility and strength.
Where You’ll Find Them: Hair spray, nail polish and perfumes.
Names They Go By: Di(2-ethylhexyl) phthalate and diethyl phthalate are common in fragrances, while dibutyl phthalate appears in many nail polishes.
What’s the Concern: Can also mimic sex hormones and may be able to affect growth of reproductive systems in fetuses. Used in hundreds of non-cosmetic plastic products, so exposure is increased.

Coal Tar
What It Is: The liquid by-product of coal distillation.
Where You’ll Find It: Shampoos aimed at killing head lice or reducing dandruff and some dark hair dyes.
What’s the Concern: Extremely carcinogenic in rodents. Might also be linked to liver disease.
What It Is: A solvent, basically a liquid that dissolves other liquids or solids.
Where You’ll Find It: Nail polish and nail polish remover.
Name It Goes By: It might appear under the names methylbenzene or phenylmethane.
What’s the Concern: Breathing in the fumes can damage kidneys and cause birth defects. People who work frequently with nail products are at most risk
