Immune Health, Everyday Resilience & Food as Medicine

Immune Health

Your immune system works quietly in the background every day – not just during cold and flu season. It helps you respond to the outside world, repair after daily wear and tear, and adapt to stress. Rather than thinking of immunity as “on” or “off”, experts now talk about immune balance and resilience over time.

Functional and longevity-focused clinicians such as Dr Andrew Huberman, Dr Casey Means, Gary Brecka and Dr Mark Hyman all emphasise a similar message: your daily choices around food, movement, sleep, light exposure and stress have a powerful influence on how your immune system feels and functions.

Immune Health Is More Than Fighting Germs

Most people only think about their immune system when they pick up an infection. In reality, immunity is deeply interwoven with metabolic health, gut function, brain health and even mood.

• Metabolic balance: Dr Casey Means highlights that stable blood sugar and low-grade inflammation are central to long-term health. When blood sugar swings wildly or ultra-processed foods dominate, the immune system can become more reactive or “on edge”.
• Nervous system and stress: Dr Andrew Huberman often explains how chronic stress shapes the body’s internal signals. When we are constantly in “fight or flight”, the immune system may not get the calm, steady foundation it needs.
• Micronutrient status: Gary Brecka and Dr Mark Hyman both stress the importance of key nutrients – vitamins, minerals, essential fats and amino acids – as building blocks for immune cells and signalling molecules.

The shared theme is simple: when we nourish the body and reduce unnecessary stressors, the immune system can do its job more smoothly in the background.

Food as Information: How Nutrition Shapes Immunity

Dr Mark Hyman often says, “food is information, not just energy.” Every meal sends chemical messages to your cells – including immune cells. Over time, these messages either support calm, balanced immune function or nudge the body towards more strain.

• Colourful plants: Vegetables, fruits, herbs and spices provide polyphenols and antioxidants that help protect cells from everyday oxidative stress.
• Quality proteins: Amino acids are needed to build immune cells, antibodies and repair tissues.
• Healthy fats: Omega-3s from fish and some plant sources help support healthy inflammatory pathways.
• Minimal ultra-processed foods: Reducing refined sugars, trans fats and highly processed snacks helps support steadier blood sugar and lower metabolic strain.

Dr Casey Means frequently points to stable blood sugar as a cornerstone of long-term health. Building meals around protein, healthy fats, fibre and whole foods can help create a steadier internal environment in which the immune system can function more comfortably.

The Gut–Immune Connection

A large proportion of the immune system sits in and around the gut. The microbes in your digestive tract interact constantly with immune cells, helping the body decide what to tolerate and what to react to.

Many experts, including Dr Hyman and Dr Means, emphasise that a healthy microbiome can support:

• Balanced immune signalling
• Better nutrient absorption
• More resilient responses to everyday challenges

Daily steps that support gut–immune harmony include:

• Eating a variety of fibre-rich plants (vegetables, fruits, legumes, whole grains if tolerated)
• Including fermented foods such as yoghurt, kefir, sauerkraut or kimchi (if tolerated)
• Staying well hydrated
• Managing stress through breath, movement and restorative practices

Foundations of Everyday Immune Resilience

From a longevity perspective, immune health is built slowly through repeatable habits. Many of the same tools highlighted by Huberman, Means, Brecka and Hyman overlap:

• Sleep: Consistent, restorative sleep supports immune memory, tissue repair and emotional steadiness.
• Movement: Regular activity helps support circulation, lymphatic flow and metabolic health – all important for immune balance.
• Light exposure: Morning daylight supports circadian rhythm, which in turn influences immune and hormonal cues.
• Stress management: Breathwork, time in nature, prayer, mindfulness and social connection help calm chronic stress signals.

Dr Andrew Huberman often reminds us that the brain and body love consistency. Small, sustainable routines – not occasional extremes – are what shift the baseline over time.

Nutrients Often Discussed for Immune Support

Whole foods are always the starting point. For some people, carefully chosen supplements can provide additional support, especially at times of greater demand or under the guidance of a health professional. Common categories discussed in relation to immune balance include:

• Vitamin C and plant antioxidants – to support the body’s natural antioxidant defences.
• Vitamin D and K2 – for general immune and bone health support, particularly where sun exposure is limited.
• Zinc and selenium – cofactors for many enzymes involved in immune function and antioxidant pathways.
• Probiotics and prebiotics – to support a healthy gut microbiome and gut–immune cross-talk.
• Mushrooms and botanicals – traditional ingredients such as reishi, shiitake, astragalus and others are used to support general immune resilience and stress balance.
• Omega-3 fatty acids – to support healthy inflammatory responses and cell membrane integrity.

These are not medicines and are not intended to diagnose or treat illness, but they may form part of a personalised wellness strategy when used alongside diet and lifestyle foundations.

Final Thought

Immune health is not just about “fighting bugs” – it is about creating an internal environment where your body feels safe, nourished and able to respond with ease. As Dr Mark Hyman reminds us, food truly can be part of our medicine, and as Dr Huberman and Dr Means emphasise, the way we move, sleep, breathe and manage stress shapes our long-term resilience.

Small, consistent changes – a more colourful plate, a short walk in the morning light, a calming evening routine or a thoughtfully chosen supplement – can add up over time. Each aligned choice is a quiet investment in a steadier, more resilient future self.
