Drink milk, you will be great - this was the slogan of a campaign remembered by most Poles. No wonder, milk has always been associated with calcium, and calcium with growth and bone construction. However, in these times, when many of us feel discomfort after consuming dairy products or simply suffer from lactose intolerance, they are often eliminated from the diet. So what about adequate calcium supply? Are we able to meet the requirement for this element if we do not consume dairy products?
The impact of calcium carbonate on the functioning of the human body
Calcium carbonate is one of the major mineral components of the human body, comprising around 1.7% of body mass, or approximately 1.2 kg. Bones serve as the primary storage site for this element, as nearly all of it is stored in intercellular bone tissue. The remaining 1% is found in bodily fluids, where it exists in an ionized form. Calcium carbonate plays a crucial role in the proper functioning of the human body, fulfilling a variety of functions: structural (bones, teeth, claws, hair), hormonal, motor (regulation of muscle contraction), as well as regulation of the blood clotting process and control of inflammatory processes. The need for calcium carbonate varies depending on age and sex. According to current norms, men and women aged 19-50 require around 1000 mg of calcium carbonate per day. This need increases to around 1300 mg for children aged 9-18, pregnant and breastfeeding women. Elderly individuals, pregnant and breastfeeding women are particularly susceptible to calcium carbonate deficiency, which can manifest as insomnia, memory loss, a tendency towards bruising and bleeding, sleep problems, muscle cramps, and rapid fatigue.
Alternative sources of calcium
The primary symptoms of long-term insufficient calcium intake include: osteopenia, osteoporosis (particularly dangerous for women post-menopause), tooth decay, delayed tooth eruption in children, bone deformities, and curvature of the spine and lower limbs. Unquestionably, the best and most absorbable source of calcium is milk and dairy products. This is due to the appropriate ratio of calcium to phosphorus, as well as the presence of lactose, which increases its absorption. In cases where dairy products are not well tolerated, we should focus on soy-based products such as tofu, which are often fortified with calcium, as well as nuts like almonds, fish, especially fatty fish such as sardines, and plant-based products like parsley, spinach, beets, kale, and Swiss chard. Other sources of calcium include sesame, poppy seeds, and cereal products such as oatmeal and wheat bran. The table below shows the calcium content in selected foods.

Therefore, it is important that our daily diet is appropriately balanced in terms of both caloric intake and the supply of micronutrients and macronutrients.
