Protecting Bone Health among Vegans

Protecting Bone Health among Vegans
            Research suggests that vegan diets may be protective against chronic illnesses such cardiovascular disease, type 2 diabetes, obesity, and certain types of cancers. Just like any other diet, concerns with this type of diet do exist, in particular in regards to bone health. Osteoporosis is a chronic debilitating bone condition characterized by reduced bone mineral density, decreased bone strength, and deterioration of bone tissue over time which increases risk of fractures in any stage of life, especially in postmenopausal women. Large previous studies have shown that vegans may be a higher risk for reduced bone density, a major determinant of osteoporosis.      
            Recent studies evaluating vegan diets and markers of osteoporosis (i.e peak bone mass, bone mineral density) found that veganism is not the root cause for lower bone mineral density that is related to osteoporosis, but is due to the limited intake of vital nutrients for bone health such as protein, calcium and vitamin D (which is required to absorb the calcium). Currently the Recommended Dietary Allowance for calcium is set at 1,000 mg for adults 19-70, 1,200 mg for women over the age of 50, and men over the age of 70. The recommendation for vitamin D is set at 600 IU for adults aged 19-70.
            In order for dietitians to enable their vegan clients to achieve the RDA for calcium experts are suggesting directing these individuals to foods with high calcium bioavailability such as turnip greens, collards, kale, soyfoods, and fortified plant milks as compared to foods with low calcium bioavailability such as spinach, and beet greens.  Experts are also recommending vegans to supplement their diet with vitamin D rich foods such as fortified soy/almond milk, orange juice, breakfast food and mushrooms along with sun exposure with skin exposed for 10 minutes a day (if feasible). In regards to protein, research has found that vegetable protein is an adequate source for protein and has been found to reduce the incidence of wrist fracture with higher intakes to a similar degree that individuals who consumed high intakes of animal proteins experience.
            Dietitians can play a unique role and are in the perfect position where they can provide evidence based advice on maintaining bone health, which is crucial due to the large amounts of misinformation that is found readily in our world today. By assessing risk factors on an individual level, ensuring that their client’s vegan diets are adequate in vitamins and minerals, and discussing the appropriateness of supplementation dietitians can make help their clients maintain their bone health in order to prevent osteoporosis.

Do you struggle with pre and post exercise nutrition?

What should i eat before and after a workout? First things first…carbohydrates, proteins and fats are important for the body before  and after exercise. Exercising muscle preferentially uses carbohydrates from stored glycogen, but fats are also an important fuel source for energy production during exercise. Fats and carbohydrates are the two major fuel sources during exercise. Fats must be translocated and broken down from their storage form before they are used. Typically there is enough carbohydrate stored as muscle glycogen for exercise but as muscle glycogen stores decline, the skeletal muscle will then use some amino acids (basic components of all protein). More specifically, the amino acid leucine is used for energy.              It is important to consume an adequate amount of carbohydrates exercise to delay fatigue and minimize gastrointestinal distress. It is also important to consume enough fluids to prev...

Child Malnutrition

New approach to childhood malnutrition may reduce relapses, deaths http://www.sciencedaily.com/releases/2015/02/150211124024.htm               Moderate acute malnutrition is experienced by 35 million children worldwide. A new study led by researchers from Washington University School of Medicine in St. Louis has suggested that feeding children until they have met target measures of arm circumference and weight may be more important than a set 12 week feeding time. However, researchers have found that the current targets, set by the World Health Organization (WHO) may not be sufficient and raising these targets slightly could significantly reduce the risk of relapse in malnourished children; a condition that has a 37% relapse rate. The study took place in rural Malawi and was comprised of 2,349 moderately malnourished children aged 6 months to 5 years old. Children were evaluated 12 months after treatment; 1,967 rec...
