Introduction
We can’t stop the clock, but we can influence how gracefully we age. While genetics play a role in how we look and feel over time, research shows that diet is a powerful tool for preserving youth, energy, and health.
An anti-ageing diet isn’t about gimmicks or trendy cleanses—it’s about consistently choosing nutrient-dense foods that support cellular health, reduce inflammation, and promote longevity.
This 2025 guide breaks down how nutrition affects ageing, lists the best foods for anti-ageing, offers a 7-day meal plan, and answers the most common questions about anti-ageing diets.
As a pharmacist, I focus on what is clinically supported, so everything here is backed by peer-reviewed science—not hype.
How Diet Affects Aging
The Science
Ageing starts deep inside our cells. One crucial sign of ageing is the length of telomeres, which are protective tips on the ends of our chromosomes that get shorter as we age.
Everyday choices like what we eat, how we manage stress, or whether we smoke can speed up ageing deep in our cells. But the good news? Loading up on antioxidant-rich foods may help protect them and slow ageing.
Another major contributor to ageing is oxidative stress, where free radicals damage the body’s DNA, proteins, and lipids. This process leads to signs of ageing like wrinkles, joint stiffness, and cognitive decline. Diets high in antioxidants, polyphenols, and omega-3s can help reduce this damage.
Chronic inflammation is the root cause of many age-related diseases, including Alzheimer’s, type 2 diabetes, and cardiovascular disease. An anti-inflammatory diet for ageing focuses on whole, unprocessed foods that reduce inflammatory markers and support immune function.
Genes vs. Lifestyle
Only about 20–30% of ageing is genetic, while environmental factors, diet, and lifestyle determine the rest. That means what you eat today can significantly influence how you age tomorrow.
Nutrients that affect mitochondrial function, insulin sensitivity, collagen production, and detoxification processes all affect skin ageing, metabolic health, and lifespan.
15 Best Anti-Ageing Foods
If you want to know how to eat for longevity, start by adding these evidence-based anti-ageing foods to your daily routine:
1. Fatty Fish
Salmon, sardines, and mackerel are rich in omega-3 fatty acids, which protect against cognitive decline and reduce skin inflammation. Omega-3s help maintain the skin’s lipid barrier, preventing dryness and reducing wrinkle formation. Studies have also linked higher omega-3 intake to longer telomeres.
2. Berries
Blueberries, strawberries, and blackberries contain anthocyanins, which protect the skin from UV damage and improve collagen synthesis. Berries also improve vascular health and may slow cognitive decline in ageing adults.
3. Leafy Greens
Spinach, kale, and Swiss chard contain lutein, an antioxidant that supports eye health, and folate, which aids in DNA repair. High in fibre and polyphenols, leafy greens also support gut health and reduce inflammation.
4. Extra Virgin Olive Oil
A cornerstone of the Mediterranean diet for anti-ageing, olive oil is rich in oleic acid and polyphenols that lower blood pressure, reduce inflammation, and protect brain function. A 2022 study linked regular olive oil consumption with lower mortality from heart disease and neurodegenerative conditions.
5. Avocados
Avocados are full of monounsaturated fats, fibre, and glutathione, a powerful antioxidant in detoxification and collagen support. They also help absorb fat-soluble vitamins like A, D, E, and K.
6. Green Tea
Rich in epigallocatechin gallate (EGCG), green tea supports skin elasticity and protects against sun-induced ageing. It also enhances fat metabolism and cognitive clarity in older adults.
7. Dark Chocolate
In moderation, dark chocolate with at least 70% cocoa content improves blood flow to the skin, enhances hydration, and protects against oxidative stress.
8. Nuts
Almonds and walnuts are rich in vitamin E, which helps maintain skin moisture and prevents oxidative skin damage. They’re also a source of plant-based omega-3s and fibre for heart health.
9. Tomatoes
Lycopene, the antioxidant that gives tomatoes their red colour, protects skin from UV radiation and collagen breakdown. Cooked tomatoes or tomato paste increase lycopene absorption.
10. Turmeric
Curcumin, turmeric’s active compound, reduces inflammation and oxidative stress. It improves skin elasticity and protects the brain from age-related changes.
11. Cruciferous Vegetables
Broccoli, Brussels sprouts, and cauliflower support liver detox pathways and hormonal balance. Their sulforaphane content helps eliminate toxins and may reduce the risk of age-related cancers.
12. Beans & Lentils
Rich in fiber, protein, and polyphenols, legumes help stabilize blood sugar and support gut health, two crucial factors in healthy aging.
13. Red Grapes
Resveratrol, found in grape skins and red wine, activates certain genes associated with extended lifespan and cellular repair. While wine should be consumed in moderation, whole grapes offer similar benefits without the alcohol.
14. Mushrooms
Shiitake and maitake mushrooms are especially good for you because they contain a rare antioxidant called ergothioneine. This antioxidant may help protect your DNA from damage caused by harmful molecules in the body.
15. Seaweed
Seaweed is rich in iodine for thyroid support, along with fucoxanthin and other antioxidants that have anti-inflammatory and anti-obesity effects.

Anti-Aging Supplements
While diet should come first, some nutrients may require supplementation—especially after age 40 when absorption declines.
Always consult your healthcare provider before starting new supplements.
Top evidence-backed anti-ageing supplements include:
- Omega-3 fatty acids for the brain, skin, and heart support
- Vitamin D3 + K2 that supports bone, brain, and cardiovascular health.
- Collagen peptides for skin elasticity and joint health
- CoQ10 for cellular energy and cardiovascular support
- Curcumin (Turmeric extract) for anti-inflammatory and antioxidant effects
- Resveratrol found in red wine and grapes; supports mitochondrial function
- Probiotics for gut health and immune modulation
Frequently Asked Questions
While no diet can completely reverse wrinkles, a consistent anti-ageing diet rich in antioxidants, healthy fats, and collagen-supporting nutrients may reduce the depth and formation of wrinkles over time. Skin health reflects internal health.
Ultra-processed foods, especially those high in refined sugars, trans fats, and preservatives, accelerate glycation, which damages collagen and elastin. These foods also fuel chronic inflammation and oxidative stress—two key drivers of premature ageing.
Not necessarily—but supplements may support healthy ageing if you’re low in specific nutrients (like vitamin D, omega-3s, or magnesium)g. A well-balanced anti-ageing diet should always be the foundation, with supplements to fill in gaps.
Final Thoughts for You
Ageing is inevitable—but how you age is, to a large extent, within your control. The anti-ageing diet isn’t about restriction or trends. It’s about consistently choosing foods that nourish your cells, reduce inflammation, and protect your skin, brain, and heart.
The most effective anti-ageing diet isn’t extreme—it’s consistent, nutrient-rich, and anti-inflammatory. You’re investing in your long-term health and appearance by eating more whole foods like fatty fish, leafy greens, berries, and olive oil and limiting processed, sugary items.
Start with minor changes. Swap sugary snacks for berries. Cook with olive oil. Add more leafy greens to your meals. The goal isn’t perfection—it’s long-term vitality. Whether you’re 35 or 65, it’s never too late to start eating for longevity.
To simplify your routine, consider anti-ageing meal delivery services emphasizing Mediterranean-style, plant-forward meals with organic ingredients.
