Your Healthy Immunity
Jun 29, 2026Winter often brings an increase in coughs, colds and other viruses, leaving many people searching for ways to "boost" their immune system. At Wellness One, we take a lifestyle medicine approach, focusing on the everyday habits that support long-term health rather than quick fixes.
Can you really "boost" your immune system?
The short answer is no.
Your immune system isn't something you can simply switch on or "boost." It's a complex network of cells, tissues and organs that works best when it's well supported and in balance.
Rather than relying on a single food or supplement, research consistently shows that nutritious food, quality sleep, regular physical activity and effective stress management provide the strongest foundation for healthy immune function.
Three simple ways to support your immune system
š³ 1. Prioritise protein
Protein provides the building blocks your body needs to produce immune cells and antibodies. Include a source of protein at each meal, such as eggs, lean meat, fish, dairy, tofu, legumes or nuts.
š 2. Eat the rainbow
Aim for a colourful variety of fruit and vegetables every day. Different colours provide different vitamins, minerals, antioxidants and fibre that help support immune health while also nourishing your gut microbiome.
š„£ 3. Feed your gut
A healthy gut plays an important role in immune function. Eating plenty of fibre-rich foods, including vegetables, fruit, legumes, wholegrains, nuts and seeds, helps nourish beneficial gut bacteria that support your immune system. Fermented foods such as yoghurt with live cultures, kefir, kimchi and sauerkraut can also help support a healthy gut microbiome.
If you're unsure whether your diet is meeting your nutritional needs, a personalised nutrition plan can help.
Healthy habits matter most
No single food can prevent you from catching a cold or the flu. The strongest evidence shows that immune health is supported by a combination of healthy lifestyle habits:
- Eat a balanced, whole-food diet.
- Get 7-9 hours of quality sleep each night.
- Stay physically active most days.
- Manage stress.
- Stay hydrated.
- Limit ultra-processed foods and excessive alcohol.
- Maintain adequate vitamin D levels, particularly if you're deficient.
If pain or stiffness is making it difficult to stay active, addressing those issues may help you maintain the regular movement that supports overall health.
The bottom line
Your immune system relies on a wide range of nutrients, including protein, zinc, iron, and vitamins A, C, D and E, to function properly. While supplements may be appropriate for people with diagnosed deficiencies or increased requirements, most people can support their immune system by focusing on nutritious food and healthy lifestyle habits rather than relying on "immune-boosting" products.
Small, consistent choices made every day have a far greater impact than any quick fix. Eating well, moving regularly, sleeping enough and managing stress provide the strongest foundation for a healthy immune system throughout the year.
