Last week I was contacted by part of the Marathon Bar team and asked if I was interested in interviewing one of their spokespeople, Dr. Janet Brill. I checked out her website and background and her credentials are extensive and impressive! Not only is she an expert in nutrition and dietetics, but she is also an expert in exercise physiology. You can check out those credentials again on this post.
So we set up our call for Friday evening and I was armed with some questions. I had some people ask me some specific questions so I addressed them first. This first question came from a reader but it is something I feel ALL women can benefit from. Haley asked about ways to incorporate more bone healthy calcium into one’s diet, outside of dairy. Truth is there are plenty of people out there who have bodies that just don’t tolerate diary very well. Diary is of course a great source of calcium but most definitely not the only way to incorporate calcium.
The first thing Dr. Brill addressed was how crucial calcium is for a healthy training diet. Bone health is something women and young girls must pay attention to. Bone issues like osteoporosis and osteopenia are not just “old people” problems. Without the right prevention, these problems can sneak up on very young women and certain damage, as Dr. Brill explained, are not reversible. That is why prevention is so important!
For those who do not tolerate dairy products well: here are some suggestions Dr. Brill gave me:
- Take Lactaid to ease the digestive issues caused by dairy
- Yogurt may be an option. It is much easier to digest than most other dairies, has important live cultures, and also a nice source of protein
- Calcium fortified soy and tofu. There are MANY ways you can incorporate these into recipes and very easy to google!
- Soy milk! I can’t drink it straight but love it on cereal and in smoothies
- Calcium enriched orange juice
- Molasses: I definitely didn’t know about this one but it is calcium rich and can be used in place of sugar
- Leafy greens: collard greens, kale, okrah, turnip greens, and spinach among others
- Salmon
- Eggs (with yolk)
Another important factor that she explained can occur in endurance athletes in amenorrhea, or the absence of menstruation in women. According to The Mayo Clinic, missing three consecutive cycles are considered amenorrheic and should is means to see a doctor. There are of course nature causes of this (pregnancy, breast feeding, and menopause) and certain medications can cause this, but what runners need to worry about is non-natural amerorrhea due to not having enough body fat and/or excessive exercise. It can also be a sign of hormonal issues as well as some other rather serious problems.
Although missing a period is not in itself particularly dangerous, it is the causes of it that must be addressed. It can be a result from an eating disorder or exercise addiction but can even occur in an otherwise healthy women who just isn’t fueling properly for the calorie expenditure of distance running.
Calcium and iron (which will be addressed in another post) are VERY important for everyone, but women in particular need to pay extra close attention, especially those putting such physical demands on the body. Going without adequate levels for too long, even without being amenorrheic, can cause serious bone damage which can result in frequent and ill-healing breaks and fractures. Dr. Brill stressed that once the damage is done, it doesn’t matter much calcium you pack in, the damage can be irreversible. She also stressed that it doesn’t matter how much calcium you are packing in your diet if you aren’t getting enough over-all calories. Without enough overall calories, you are setting yourself up for these bone problems in addition to MANY other problems that will not only effect your performance, but you’re health for life including heart health and reproductive issues.
So thank you Haley for posing that question! Let me know if you are wondering anything further and I will try to get those answers from Dr. Janet Brill!
Stay tuned for more expert advice!
