Common foods can help you look younger. British dietitian Gabriela Peacock shared how small changes to your diet can make you look younger in as little as two weeks.
We often chalk a youthful appearance up to ‘good genes.’ Peacock says genetics do play a role in aging. But diet can offset some of that influence. New dietary approaches aim to rejuvenate cells by including certain foods.
Mushrooms
Cortisol, the stress hormone, affects sleep, energy, hormones, mood, nutrient balance, and weight — and it can accelerate biological aging.
Peacock says mushrooms can help counter stress. Many varieties contain adaptogens — compounds that help the body manage stress and recover. Mushrooms also provide beta-glucan, a prebiotic that feeds gut bacteria, has anti-inflammatory effects, and supports the immune system.
Whether you eat mushrooms as a side dish or take them as supplements, they can be a useful part of an anti-aging diet.
Coffee and Green Tea
Caffeine lifts metabolism and stimulates the nervous system, helping the body release fat from fat cells while improving focus and mood.
Coffee is a rich source of antioxidants and other bioactive compounds that reduce inflammation, lower insulin resistance, and protect cells from damage.
But coffee isn’t the only option. Peacock also recommends caffeinated teas, particularly green tea and yerba mate. These beverages contain compounds linked to longevity.
Regular coffee and tea consumption may also help protect the brain from neurodegenerative decline.
Wine
Peacock cites studies suggesting that moderate alcohol consumption can be compatible with a long, healthy life.
Red wine in particular contains resveratrol, a polyphenol associated with reduced oxidative stress, improved cellular energy, healthier metabolism, balanced blood sugar, and better brain health.
She suggests enjoying one to two glasses of wine at a weekend lunch rather than in the evening. The key is moderation: alcohol is calorie-dense and can strain the liver. Excessive drinking promotes weight gain, especially around the abdomen.
Magnesium-Rich Foods
Magnesium acts as a natural relaxant and supports many body functions. It can lower anxiety, reduce stress, and help control blood pressure. Increasing magnesium intake may slow some aspects of aging, the Daily Mail reports.
Peacock advises eating more magnesium-rich foods such as dark leafy greens, nuts, seeds, whole grains, beans, chickpeas, lentils, and dark chocolate.
Fish Skin and Seaweed
Dietitians often highlight fish for its anti-aging benefits. Peacock also recommends eating fish skin, which is high in anti-inflammatory fatty acids linked to longevity. Make sure the fish comes from clean waters.
Seaweed is a good source of iodine. Iodine helps the body make thyroid hormones, which regulate metabolism, energy levels, and cognitive function.
Other Anti-Aging Dietary Tips from Gabriela Peacock
Boost your omega-3 intake by using hemp, flaxseed, or pumpkin oil on salads and other dishes.
Don’t forget olives: they are rich in oleic acid, a fat associated with longer life.
Peacock also suggests scheduling calorie-restriction days and compressing eating into an eight-hour window. On those days, cold showers, sauna sessions, and exercise can be beneficial.
She recommends prioritizing plant-based foods for their polyphenols, which support cellular health.
Follow these tips and you may notice a fresher, younger-looking appearance in about two weeks, along with less fatigue and better overall health, Peacock says.
