🧵#Iron
The most important factor in how much dietary iron you absorb is not whether it is heme or non-heme, plant🌱or animal🐮 - it is your current #iron #status.
If you are iron #deficient you may absorb 25% from plants, if you are iron #replete you may absorb less than 1%. Image
#IronStatus (is your body low in stores?) is the main factor determining how much iron you will absorb from your diet🌱🥩. The body doesn't want too much so high absorption ONLY occurs if your #storage is #low. The body is smart🩸🧠🫀🫁💡! Image
The body is very good at recycling #iron from dead red blood cells.
Only 5-10% of our iron needs come from our #diet🍽️

Main Finding:
Data showed 15 more cases of hip fracture in vegans vs meat eaters per 1000 ppl over a 10 year period

⚠️Consider: All enrolled in the study between 1993-2001, last diet assessment 2010
Why it matters:
1. Much #lower knowledge about veganism 10-15-20 y ago vs today
2. Less awareness re protein, RT/muscle & bone health
3. #PlantBased protein options uncommon in marketplace

Reasons for increased fractures in vegans, *important statement: "Fractures at some sites, especially at the hip, may also be more related to osteoporosis than fractures
