    Calcium

    see further down this page for calcium-rich recipes

    Calcium is a major mineral: the average adult is made up of just over a kilo (around 2% of total body weight).

    99% of this is found in the bones and teeth, and the remainder is used for the contraction of muscles, nerve

    function, enzyme activity and blood clotting.

    Calcium Requirements

    The UK Department of Health's Reference Nutrient Intakes (the daily amount that is enough for 97% of people:

    similar to RDAs used previously in the UK) are as follows.1

    Age/Sex Calcium requirement (mg/day)

    0-12 months 525

    1-3 years 350

    4-6 years 450

    7-10 years 550

    Teenage girls 800

    Teenage boys 1000

    Adult men & women 700

    Breastfeeding womenno increase

    Vegan Sources of Calcium

    Good plant sources of calcium include:

    Green leafy vegetables: spring greens, kale, broccoli, parsley.

    It is important to note that spinach is not a good source of calcium. It is high in calcium, but the calcium is

    bound to oxalates and therefore poorly absorbed

    Fortified foods such as soya milk

    White flour (as calcium is added by law) and white flour products

    Calcium-set tofu

    Oranges

    Ground sesame seeds (tahini)

    The calcium content is high but variable and absorption of calcium from tahini is not proven so tahini should

    not be relied upon as a main source

    Figs and black molasses

    Drinking hard water can provide 200mg of calcium daily, although soft water contains almost none2

    Ensuring an adequate intake of calcium

    A study in the UK of 34,696 adults, over five years, found that the vegans studied had a higher risk of bone

    fracture than the meat eaters, fish eaters and vegetarians studied. This appeared to be a result of their lower

    calcium intake - no increase in risk was found in those vegans consuming at least 525 mg of calcium per day - and

    highlights the importance of ensuring an adequate intake of calcium.4 Recommended intakes are given in Calcium

    Requirements above.

    Calcium is a team player

    Calcium is sometimes thought of as the 'bone-builder', but it should not be viewed in isolation. Other nutrients

    including vitamin D, vitamin K, protein and potassium play an important part in building bones. Exercise also helps

    to build bones.

    Vitamin D assists with calcium absorption so it is important to ensure a supply. Expose your face and arms to the

    sun for approximately 15 minutes pe r day. If your sun exposure is limited (for example in a British Winter), or if

    you are dark skinned make sure that you get 10 to 20 micrograms of vitamin D2 each day from fortified food or a

    supplement such asVEG1 available from The Vegan Society.

    Other Factors To Consider:

    Salt (sodium) causes calcium loss, so opt for low-sodium salt (e.g. Losalt) and low-sodium foods.

    Caffeine reduces calcium absorption so reduce your intake of caffeinated foods and drinks such as coffee and tea.

    Vegetables and fruit improve calcium balance so eat plenty.

    Protein stimulates bone building so it is important to ensure an adequate intake of protein, but avoid excesses.

    Moderate protein intake - about one gram of protein per kilogram of body weight per day - is probably ideal.
