Bones. Ever watched the TV show? Awesome stuff. The lead character, Dr. Temperance Brennan is a hot forensic anthropologist who figures out how folks die from examining their bones. Yeah I know. There’s no such thing as a hot forensic anthropologist. Only on TV. Enough of the digression. What about your bones? How should you keep ‘em healthy? If you heard that eating lots of protein is bad for your bones, you heard wrong my friend. Your bones best friends include: weight-bearing exercise, plenty of calcium, sunshine (need that Vit D), and lotsa protein. Yep. A Protein Rush post-workout will keep them bones hard and healthy.
Association between dietary protein and fracture risk is unclear. We examined association between energy-adjusted protein intake and hip fracture risk in elders. The risk of hip fracture was reduced in upper quartiles of protein intake when compared with lowest quartile.
Studies of the association between dietary protein intake and hip fracture risk are conflicting. Therefore, we examined protein intake and hip fracture risk in a population-based group of elderly men and women. METHODS: Five hundred seventy-six women and 370 men from the Framingham Osteoporosis Study with no previous history of hip fracture completed Food Frequency Questionnaires. Energy-adjusted protein intake was evaluated as a continuous variable and as quartiles. Incidence rates and hazard ratios were calculated, adjusting for age, BMI, sex, and energy intake. RESULTS: Among 946 participants (mean age 75 years), mean protein intake was found to be 68 gm/d. Increased protein intake was associated with a decreased risk of hip fracture compared to those in the lowest quartile of protein intake (Q2 HR = 0.70, Q3 HR = 0.56, and Q4 HR = 0.63; all p values >/= 0.044), p for trend was 0.07. When a threshold effect was considered (Q2-4 vs Q1), intakes in the higher quartiles combined were associated with a significantly lower risk for hip fracture (HR = 0.63; p = 0.04).
Our results are consistent with reduced risk of hip fracture with higher dietary protein intake. Larger prospective studies are needed to confirm and extend this finding in elderly men and women.(1)
Scientific Proof, hah!
