To prevent oxidative stress, it's essential to limit the factors which can encourage it, such as tobacco or sun exposure. Having a healthy lifestyle and a balanced diet will also help reinforce your body so it's more capable of fighting off these free radicals. But the best way to combat this oxidative stress is to fill up on antioxidants! - In your diet: focus on vitamin A (tuna, cheese, eggs, fruits and vegetables with orange and red flesh, carrots, spinach, lamb's lettuce, broccoli, green beans), C (citrus fruits, exotic fruits, parsley, kiwi, strawberries, watercress, brussels sprouts, potatoes) and E (sunflower oil, corn oil, grapeseed oil, almonds, cashew nuts, prawns, crab, broccoli, avocado, asparagus), the trace-elements (selenium, zinc, copper) and polyphenols (these are found in several different fruits and vegetables, but are also responsible for the antioxidant powers of wine and tea). - In your cosmetics: Given that you would have to eat a massive amount of antioxidant-rich foods to see a real difference, facial skincare creams lend a helping hand as these antioxidants are integrated almost systematically into the formulas of both moisturisers and anti-ageing creams. - In your nutritional supplements: if you have a healthy balanced diet, you shouldn't need nutritional supplements. However, if you want to give them a go, pay close attention to the mixtures and dosages and ask your pharmacist for advice.
