Good nutrition can guard against osteoporosis

Family Health Magazine - Boost  Your Bone StrengthBone loss is often called the silent thief, as it can occur without any symptoms. With osteoporosis, bones become thin, porous and more likely to break – especially the hip, spine and wrists. Osteoporosis Canada reports that such bone fractures are more common than heart attack, stroke and breast cancer combined. One in three women and one in five men will suffer from an osteoporotic fracture during their lifetime. The result can significantly challenge a person’s quality of life. These fractures can reduce mobility and independence, change appearance and lower self-esteem.

Your diet plays an important role in preserving bone strength. By following some simple nutrition tips, you can prevent or manage osteoporosis.

Tip 1 – Get enough calcium

Calcium provides structure and integrity to bones. It is key to preventing osteoporosis. In childhood and adolescence, getting enough calcium in the diet is critical for bone growth and the development of peak bone mass. For this reason, osteoporosis is considered a childhood disease with consequences later in life. Calcium continues to remain important as we age, reducing the rate of bone loss and the risk of fractures.

The foods highest in calcium include:

  • dairy products such as milk, yogurt and cheese
  • and calcium-fortified beverages like fortified orange juice and fortified soy, rice and almond drinks. Be sure to shake the containers of these beverages really well. The calcium often settles at the bottom.

Consuming three servings of these foods per day is an easy way to ensure you are getting enough. One serving is equal to one cup of milk or calcium fortified beverage, three-quarters of a cup of yogurt, or 1½ ounces (40 grams) of cheese.

Other sources of calcium are:

  • molasses
  • canned salmon or sardines (with bones)
  • almonds
  • legumes like baked beans, white beans, navy beans or chickpeas
  • green veggies like collards, kale, bok choy, rapini, broccoli
  • and tofu.

If you do not get enough calcium from your diet, speak with your dietitian and doctor about calcium supplements.

Tip 2 – Take vitamin D

Vitamin D is key for bone health as it encourages calcium to be absorbed. Vitamin D is known as the sunshine vitamin. When sunlight strikes the skin, it can trigger the creation of vitamin D. However, this is not a very reliable way to ensure we get enough of this essential vitamin. Variations in sun exposure, skin pigmentation, and use of sunscreen all affect the production of vitamin D.

Health Canada recommends that all adults up to age 70 get 600 IU of vitamin D per day from food and supplements. A few foods contain vitamin D:

  • fatty fish
  • egg yolks
  • milk
  • and fortified soy, rice and almond beverages.

As with sun exposure, it is difficult to get enough vitamin D from food alone. Health Canada recommends that in addition to following a healthy balanced diet, all adults over age 50 should take a daily vitamin D supplement.

For those over age 70, 800 IU per day is recommended. Some experts suggest that even higher levels of vitamin D supplements may help those who have osteoporosis or are at risk. Speak with your dietitian and doctor about what is best for you.

Tip 3 – Watch sodium

Sodium makes the kidneys release calcium. For this reason, consuming too much sodium can be bad for your bones. Aim for less than 2,300 milligrams of sodium per day – the amount in one teaspoon of salt. Cutting back on the amount of salt you add to food during cooking or at the table can help. However, often the bigger source of sodium in the diet is from processed and prepared foods.

Common sources of sodium include convenience foods like canned soups, frozen dinners, and packaged pasta and rice mixes. Condiments like soy sauce, barbecue sauce, and certain seasonings can also have a high level of sodium. Processed meats, such as deli meats, bacon and smoked salmon, are also sources of sodium.

To assess the amount of sodium, read the Nutrition Facts panel on packaged food. Look at the amount of sodium, and compare brands. When reading product labels, be sure to consider portion size. Sodium levels will be higher with larger portions. Where possible, cook from scratch, choose lower sodium products and substitute herbs and spices for salt when cooking.

Tip 4 – Limit caffeine

Caffeine from beverages like coffee, tea and cola increase the amount of calcium your kidneys release in urine. This occurs up to three hours after having the drink. Research shows this effect seems to be the worst for women who are not meeting their daily calcium requirement.

Adults should avoid consuming more than 400 milligrams of caffeine per day.

Adults should avoid consuming more than 400 milligrams of caffeine per day.  With each 240 mL cup of coffee, about 65 milligrams of calcium is leached from your bones. You can offset this loss by adding one-quarter of a cup (60 mL) of milk or calcium-fortified beverage to your coffee. If possible, choose beverages that do not have caffeine. If you are a coffee drinker, consider selecting cappuccinos and lattes for the extra calcium they provide. Be sure to hit your daily calcium target with food or supplements.Be aware that many household mugs and coffee shop cup sizes are typically 500 mL or more in volume. Pregnant and breastfeeding women should aim for less than 300 milligrams. Children should have only a fraction of this level of caffeine, if any.

Tip 5 – Eat enough protein and calories

An excessive amount of protein is not good for bone health. However, research shows a lack of protein in your diet increases the risk of hip fractures. Protein is important to the structure of bone. Some people are at risk of not consuming enough protein, including those who:

  • have poorly planned vegetarian diets
  • have eating disorders
  • skimp on calories or protein-rich foods in an effort to lose weight
  • live alone and do not cook meat, chicken and fish often.  

Be sure your meals contain good sources of foods rich in protein. Include legumes, meat, poultry, seafood, eggs, dairy foods, nuts, seeds and tofu.

The media and health professionals place much emphasis on reducing obesity. However, not everyone needs to cut back on calories and lose weight. In fact, consuming too few calories and having a low body weight can put you at risk for osteoporosis. This condition is more common in people who have a small, thin body frame and bone structure. If you weigh less than 60 kilograms (132 pounds), or have lost a large amount of weight, you could be at risk. Being too thin means you have less bone to lose as you get older.

"I am a psychologist in private practice and it is very important to me that my clients have the best care with other health care professionals. For that reason Health Stand Nutrition is my only source for exceptional Dietitians. Andrea and her team provide highly knowledgeable, compassionate, and real world support to my clients who require assistance with food lifestyle. I trust my clients to them and you would be in excellent hands making them part of your health care team."
Adele Fox, Psychologist
“This is the first time I feel satisfied; my cravings have diminished dramatically and I have a whole new relationship with food. I am eating guilt-free for the first time in my life. My energy has also dramatically increased and I feel great!
Rhonda Jenkins, Nutrition Counseling Client
“The Dieticians at Health Stand Nutrition help you to take action on the science behind eating well by making it practical, understandable, and fun. Their office is cozy and not at all clinical or intimidating. I felt like I was sitting down with a really smart, caring friend who wanted to help me make the best choices for my lifestyle and food preferences. They really are the best in the business.”
Marty Avery, Nutrition Counseling Client
“I have come to think of the program as a one stop shopping excursion for everything one needs to know about creating a joyous relationship with food and our bodies. In a single word, the course has gifted me with freedom from the punishing rigidity of disordered eating, old stories that never were true, and body dysmorphia that did nothing but make me lose sight of a body that has done everything I've asked, despite my careless dismissal of her needs. Now when I look in the mirror I find myself shifting from harsh criticism to gentle gratitude.”
Lynn Haley, Pursuit of Healthiness Online Course Participant
“I spent 3 hours when first diagnosed with type 2 diabetes. I learned more from my Dietitian about food in those 3 hours than I had learned in all the years of my life. I also love the newsletter, there is always something to learn.”
Peter Whitehead, Nutrition Counseling Client
“I didn’t realize how strong my “diet mentality” was, and all the rules I had in my head about food. I was in a cycle of reward/punish/binge/cringe. I booked with your business very reluctantly, on the repeated advice of my doctor, to get my slowly rising cholesterol levels in check. I thought I knew everything about food, and my behaviour with food, but I was definitely re-schooled. My weight is creeping down, I feel good about my diet, exercise, body image, and lifestyle.”
Amy Floyd, Nutrition Counseling Client
“Thanks Andrea for an amazing presentation, I have heard all positive remarks from attendees and the evaluations show the same sentiment. It is really gratifying when a speaker does their “homework” and weaves in our profession’s day to day challenges within their content, you did an awesome job of this! You truly took the “die” out of Dietician! Your information on healthy eating and simplifying how we can work towards this as we are all so busy really hit the mark. Andrea connects very well with her audience; she is energetic, funny, and very approachable.”
Carole Ann LaGrange, Transfusion Medicine Safety Officer

Event Planner for Laboratory Diagnostic Imaging Annual Event

I am a family physician who sees patients with a myriad of eating concerns – from wanting to know how to plan healthy meals for active families, to weight loss, to eating disorders, and so on. I cannot recommend the Health Stand team highly enough. I have worked with (and been to!) other Dieticians in the past and too often find that they just ask for food logs and make suggestions that are easily obtained online or in books. The Dieticians at Health Stand offer much more than just telling clients what they “should be eating.” In contrast, the team really does more of a counselling practice, and they work hard to help their clients learn more about why their eating habits may be off track and not optimal for them, as well as helping people to effect change at a deep level that, most importantly, is sustainable for lifetime health.”
Dr. Deb Putnam, Family Physician

“I am a busy mom, with kids in high level sports, working full-time downtown, and running our home acreage outside the City. I now have the knowledge and tools I need to plan for and manage the chaos of meal planning.”
Gillian Gray, Pursuit of Healthiness Online Course Participant
“As a construction company, we select speakers who can relate to our industry and its employees. Andrea’s message was delivered with humor and empathy. She makes people feel as though they can make changes without leaving behind every favorite food. Andrea focused her presentation on healthy eating as a way to keep energy high throughout the day. This message and the way it was delivered resonated with our predominantly male, blue collar culture. I would highly recommend Andrea as a speaker for groups such as ours. She will get your message across without alienating anyone in your audience – which is a huge hurdle when trying to introduce a wellness program in the workplace!”
Stephanie Wood, HR and Safety Manager

Fisher Construction Group, Burlington, WA

I found my Dietitian warm, funny, and skilled at teaching nutrition concepts without the overwhelm. The general approach of each session was to mix science with emotion, which was exceedingly effective in helping me shift my perspective on food from one of anxiety to one of joy and curiosity.”
Erin Kronstedt, Nutrition Counseling Client
“Excellent presentation! What a refreshing change to have a speaker inspire rather than “lecture” about nutrition. Your captivating stories, tips and overall approach to healthy eating uplifts and puts people at ease. It was great to hear we don’t need to strive to be perfect eaters, and that small changes really can make a difference in how we feel and in our health. Thanks to Andrea, we have solutions to our everyday nutrition challenges that can actually work in real life!”
Tina Tamagi, Human Resources

“Had I not joined this course I would have struggled with no focus, low energy, and mindless eating. Excellent teaching and motivation. This is not just a course, it is a nutrition club with mentorship, support, and connections with other people with similar situations.”
