How Seasonal Foods Support Immunity, Energy, Hormones & Blood Sugar
As we head into the darker months, it’s common to notice dips in mood, motivation and immunity. Colder weather, less sunlight, and more time indoors all affect our metabolism, gut health, sleep, and energy.
One of the simplest, most effective ways to support your body during this seasonal shift is to eat foods that naturally grow at this time of year. Seasonal foods offer the nutrients our bodies need right now.
Why Eating Seasonally Matters
When fruit and veg are grown in season and harvested at the right time, they contain:
Higher Nutrient Density
Seasonal produce is fresher and spends less time in transport or storage, meaning it retains more vitamins (particularly vitamin C, folate, and antioxidants), which are essential for immune health, energy production and cellular repair.
More Fibre to Support Blood Sugar & Digestion
Autumn vegetables such as squash, beets, brassicas and root veg are higher in fibre.
Fibre helps to:
stabilise blood sugar and prevent energy crashes
keep us fuller for longer, reducing cravings
feed beneficial gut bacteria (supporting metabolism, mood, immune and hormone balance)
Antioxidants to Protect Cells During Winter
Cold weather, increased viruses and less sunlight place extra stress on the body.
Seasonal foods contain compounds such as beta-carotene, polyphenols, flavonoids and nitrates, which reduce inflammation, support immune resilience and improve blood flow.
Better Alignment with Our Natural Rhythms
Autumn/winter produce is warming, grounding and energy-sustaining, unlike summer foods, which are cooling and hydrating. Nature provides what we need when we need it.
What’s in Season in November
Pumpkin & Squash
Rich in beta-carotene (vitamin A precursor) for immunity, skin and eye health; high in fibre to support balanced blood sugar and gut health.
Brussels Sprouts
Vitamin C for immune defence and collagen; vitamin K for bone health; sulforaphane for detoxification and hormone metabolism.
Kale & Cabbage
Antioxidants and fibre for gut health, hormone balance and reducing inflammation; support liver detox pathways.
Beetroot
Natural nitrates improve blood flow, stamina and brain function; support liver detoxification; and are high in folate for mood and energy.
Parsnips
Comforting but still high in fibre and vitamin C; a gentle way to enjoy sweeter flavours without spiking blood sugar.
Leeks & Onions
Prebiotic fibres that feed good gut bacteria, supporting digestion, immunity, metabolism and mood.
Apples & Pears
High in pectin (a soluble fibre) that slows glucose release, supports gut and heart health, and may improve cholesterol markers.
Cranberries
Rich in polyphenols and vitamin C, it supports urinary tract health and immune function.
Blood Sugar & Seasonal Eating: Why It Helps
Many of these November foods naturally pair fibre + complex carbohydrates + antioxidants, which helps:
reduce post-meal glucose spikes
improve insulin sensitivity
maintain steady energy
support hormonal balance (particularly during perimenopause and menopause)
Root vegetables can still fit into a blood-sugar-friendly diet when combined with protein, healthy fats or fibre to slow digestion.
