Immunity in the spring: which foods and vitamins really matter

Spring is supposed to be a time for awakening, but many people feel tired, often get sick and say "I have no strength". After winter, the body comes out of a period with less sun, heavier food and more viruses – it is normal for the immune system to need additional support. The good sign is that we don't need miraculous regimens, but a few reasonable changes on the plate and, if necessary, well-chosen supplements.

The basis: not "immunity in a pill", but overall nutrition

Doctors and nutritionists agree: immunity is not "turned on" with one vitamin, but is built up from a holistic way of eating. A diet rich in vegetables, fruits, whole grains, nuts, seeds, fish and olive oil – a "Mediterranean" type model – is associated with lower levels of inflammation and better protection against chronic diseases. This is the background against which the individual vitamins and minerals work best.

In two words: if the main menu is fast food, sugary drinks and a lot of white flour, neither vitamin C nor zinc will "save" immunity. Therefore, the first step is to add more "real" food – colorful vegetables, seasonal fruits, legumes, whole grains, quality fats.

Which foods to include in the spring menu

Citrus fruits and colorful fruits – oranges, grapefruits, lemons, kiwi, strawberries. They are rich in vitamin C and antioxidants that support white blood cells and protection against infections. One or two servings a day are perfectly sufficient for most people.

Green leafy vegetables – spinach, sorrel, nettle, kale, green salad. They provide vitamin A, C, K, folic acid, fiber and a wide range of antioxidants. Besides helping the immune system, they also support the intestinal microflora, which is a key part of the body's protection.

Garlic and ginger – the classic "for immunity" has a reason to exist. Both plants contain active substances with antibacterial and antiviral properties and are associated with a milder course of colds and infections. There is no need for extremes – 1–2 cloves of garlic and a little fresh or dried ginger in the food daily are perfectly sufficient.

Yogurt and fermented foods – the live bacteria in yogurt, kefir, some types of pickles and kombucha support gut health. And healthy gut = better immune response. Choose products without unnecessary sugar and with real live cultures.

Nuts and seeds – walnuts, almonds, hazelnuts, pumpkin and sunflower seeds. They provide vitamin E, healthy fats, zinc and other trace elements with antioxidant and anti-inflammatory effects. A handful of nuts a day is a good guide.

Fish and eggs – fatty fish (salmon, mackerel, herring, sardines) are a source of omega-3 fatty acids and vitamin D, and eggs – of quality protein, vitamin A, D and B-group. Spring often "reminds" us that vitamin D stores after winter are not ideal, so fish and eggs are valuable guests on the table.

Vitamins and minerals worth considering

Vitamin C – participates in the work of immune cells, in the protection against free radicals and in the regeneration of tissues. With a balanced diet, it can often be obtained only with food (citrus fruits, kiwi, peppers, broccoli, strawberries). Supplements make sense in case of proven deficiency, smokers, chronic stress or frequent infections – and in reasonable doses, not "shock" grams.

Vitamin D – many people in our region enter the spring with low levels due to lack of sun during the winter. Vitamin D is involved in the regulation of the immune response and is associated with a lower risk of severe respiratory infections. It is a good practice to do a test and, in case of deficiency, discuss with a doctor the appropriate dose of the supplement, instead of taking it "blindly".

Zinc – a trace element that participates in the development and function of immune cells and in tissue healing. It is found in meat, eggs, dairy products, nuts and seeds. Supplements may make sense for people with restricted diets (strict vegans, very monotonous diet), but long-term intake of high doses without control is not a good idea.

Vitamin A and E – support protective barriers (skin, mucous membranes) and have an antioxidant effect. They are usually obtained sufficiently through vegetables (carrots, pumpkin, leafy greens), eggs, dairy products and nuts, so with a varied menu, separate supplements are rarely needed.

When supplements make sense – and when we just fill the cupboard

In recent years, immune supplements have become a separate industry – bottles, capsules, powders with promises of "iron immunity". The reality is more modest. Scientific data support the benefits of vitamin C, D and zinc in people with deficiencies or increased needs, but do not show a magical effect in already well-fed, healthy adults.

Key questions to ask ourselves before buying the third box "for immunity": do I have a real deficiency or a high risk of one? Have I consulted with a doctor or pharmacist? Do I first correct my diet, sleep and stress, or do I rely only on a pill? Supplements can be a useful tool, but should not replace normal, wholesome food.

Small, realistic steps for stronger immunity in the spring

Instead of looking for a "miracle for three days", it makes more sense to focus on small changes that we can maintain:

• put at least half a plate of vegetables in at least two meals a day;
• replace at least a few sugary drinks a week with water, herbal tea or water with lemon;
• add fish at least 1–2 times a week and a handful of nuts almost every day;
• go out in daylight for 15–20 minutes every day when possible;
• try to go to bed at the same time and not "steal" from sleep.

Immunity is not an armor that we put on for spring and take off in the summer. It is the result of how we take care of ourselves every day – with what we eat, how we sleep, how we move and how we give ourselves a break. Spring is just a good reminder to look at our plate and calendar and say: "Can I take one small step in a better direction today?"
