We need about 1000 mg of calcium per day for healthy and strong bones, everyone does not only vegans. As we age we need more: An intake of minimum 1200 mg of calcium is recommended for women over 51 years and for men over 70 years.
There is a trap; if you do not know of it, you might be eating loads of calcium but it will *not* be absorbed in your body, here goes: Oxalic acid, which is found in spinach, rhubarb, chard, and beet greens binds with the calcium in those foods and reduces its absorption. These foods should not be considered good sources of calcium. Calcium in other green vegetables is well absorbed. Dietary fiber has little effect on calcium absorption though.
Protein’s effect on calcium needs and bones remains uncertain.
To maintain strong and healthy bones it is recommended you do regular weight-bearing exercise such as walking. You will also need to keep an eye on your sodium intake because it increases the amount of calcium lost in urine (about 20 mg of calcium are lost with each gram of sodium in the diet) and higher dietary sodium is associated with lower bone density.
How much sodium do we need? well the answer is “we do not know exactly”, look at these figures:
- United States Department of Agriculture (USDA): 2300 mg.
- American Heart Association (AHA): 1500 mg.
- Academy of Nutrition and Dietetics (AND): 1500 to 2300 mg.
- American Diabetes Association (ADA): 1500 to 2300 mg.
So… there is definitely a consensus among these organizations that we should aim for less than 1500 mg of sodium per day, and definitely not more than 2300 mg.
1500 mg of sodium equals about 3/4 teaspoons or 3.75 grams of salt per day, while 2300 mg equals about one teaspoon and 6 grams of salt per day.
And you will need Vitamin D together with the calcium for best absorption ; best source is the sun and you get that with a nice walk.
