Winter nutrition tips: How to get enough calcium and keep your bones healthy despite less sunlight

Calcium is one of the most important minerals for the human body. It plays a key role in building and maintaining strong bones and teeth, supporting muscle function, and aiding nerve signalling. During winter, when sunlight exposure decreases and dietary habits often change, ensuring adequate calcium intake becomes even more crucial. Here’s how you can boost your calcium consumption during the colder months.

Dairy products like milk, cheese, and yoghurt are among the richest sources of calcium. For those who are lactose intolerant or follow a plant-based diet, fortified plant-based milks such as soy, almond, or oat milk can provide similar benefits. Incorporating these foods into daily meals, such as having a glass of milk with breakfast or adding yoghurt to snacks, ensures your body receives enough calcium even during winter.

Dark leafy vegetables like kale, spinach, and broccoli are excellent sources of calcium. Other vegetables such as bok choy, okra, and turnip greens also contribute significantly to daily calcium intake. Cooking methods matter: lightly steaming these vegetables preserves calcium content while improving digestibility. Including at least one serving of these greens in lunch or dinner can strengthen your bones throughout the colder months.

Certain nuts and seeds, including almonds, chia seeds, sesame seeds, and sunflower seeds, are packed with calcium. Legumes like chickpeas, white beans, and lentils also contribute to bone health. Winter snacks can be made more nutritious by combining these ingredients, like a handful of almonds with roasted chickpeas or a sprinkle of sesame seeds over salads, helping maintain adequate calcium levels without much effort.

Vitamin D is essential for calcium absorption, yet during winter, sun exposure decreases, leading to potential deficiencies. Including vitamin D-rich foods such as fatty fish, egg yolks, and fortified cereals can help. In some cases, a doctor-recommended vitamin D supplement may be necessary. Ensuring sufficient vitamin D intake during winter maximises the calcium your body absorbs and supports overall bone health.

Certain foods and drinks, like excessive coffee, tea, and carbonated beverages, can reduce calcium absorption. Maintaining a balanced diet rich in fruits, vegetables, whole grains, and protein alongside calcium-rich foods ensures your body effectively uses the calcium you consume. Simple lifestyle changes, such as having green tea in moderation and avoiding high-salt processed foods, can further support bone strength during the winter months.
