Nutrition Tip: Calcium can come from sources other than milk


From Office of Nutrition Services

 

Everyone needs calcium. For most college students, the recommendation is to get 1,000 milligrams/day. Not everyone wants to eat or drink dairy products as the sole source of that. For many people, this can be a health concern as well. Allergies and intolerances can make digesting the proteins in dairy difficult, while lactose intolerance can be dealt with by using Lactaid milk and other dairy products.

CALCIUM SOURCE: Salmon and other fish
are high in calcium. For most college
students, the recommendation is to get
1,000 milligrams a day.

Since protein increases the calcium excretion rate, plant-based sources of calcium are actually more effective then animal-based sources in most cases. Milk is mostly proteins, which makes it one of the less bio-available forms of calcium.

Alternative "milks" are often enriched or fortified with calcium. These include rice, soy and nut milks. For those who don't want the liquids or for whom the taste is an issue, there are other options as well.

Fish is high in calcium. Those which are eaten with the bones (smelt, sardines, canned mackerel or salmon) are highest. Cooked shrimp and raw oysters also are high in calcium.

Blackstrap molasses is very high in calcium, and can be used for both sweet and savory applications. It is a byproduct of sugar production and contains all of the minerals lost — in the purification process — to sugar itself .

Dark green leafy vegetables also are high in calcium. But, in some, it is not readily absorbed due to high amounts of oxalates (an example is spinach). The best source of bio-available calcium from greens is kale, as well as turnip greens.  

Of the grains, quinoa, corn meal, whole wheat flour and dark rye flour are all high in calcium, though some of this can be lost in the mix of ingredients when cooked.

Nuts and seeds also are high in calcium, though should only be eaten in moderation due to their high fat content. Sesame seeds contain the most calcium per cup, followed by almonds and hazelnuts. Walnuts and sunflower seeds are lowest in calcium.

Additional sources of calcium include: seaweeds (nori, wakame and agar-agar), beans and peas, broccoli and figs.
