What you eat can boost your immunity, your health and your longevity. Here, the best foods for a long life — and which ones to avoid.
Longevity isn’t just about delaying death — it’s about enjoying more years of health and vitality. In her book, The Longevity Diet, dietician Leslie Beck outlines the ways food choices affect the aging process and help to delay the onset of age-related chronic illnesses.
First, certain foods can cause or prevent inflammation in the body. We’re not just talking arthritis; chronic inflammation also contributes to illnesses like Alzheimer’s disease, heart attack and type 2 diabetes. Foods that are high in antioxidants, omega-3 fatty acids, monounsaturated fat and phytochemicals promote the production of anti-inflammatory compounds. In contrast, foods which are high in fat, refined sugars and refined starches can promote inflammation.
Second, foods containing high levels of antioxidants combat the harmful effects of free radicals — compounds which can damage proteins, cell membranes and genes. Free radical damage accumulates over the years when the body can’t produce enough of its own antioxidant enzymes to keep up. You’ve likely heard some of the big names like polyphenols, phytochemicals (such as flavonoids, beta carotene and resveratrol), vitamins C and E and selenium.
Top Foods for Longevity
1. Almonds. Love them for their vitamin E and healthy fats. They make a great addition to salads and cereals, or enjoy almond butter on toast, apples or crackers.
What about other nuts? Experts agree that most nuts offer healthy benefits too. For instances, walnuts have a hefty dose of alpha linolenic acid (ALA) content — an omega-3 fatty acid that helps reduce inflammation.
2. Avocados. This fruit is a not just a source of healthy fat, it’s also got folate (an essential B-vitamin) as well as vitamin B6, potassium and glutathione, a powerful antioxidant. Its creamy texture works well in dips and spreads.
3. Beets. Those bright pigments are thought to help ward off certain cancers like colon cancer. They’re also high in folate and manganese, and the betaine found in beets can help fight aging and inflammation. Try roasting them along with other winter vegetables or grate them on a salad.
6. Cabbage. Got to love those glucosinolates — another type of phytochemical that target free radicals. Try it in a sandwich instead of lettuce or braise it with apples and red wine.
7. Dark chocolate. Yes, you can treat yourself. Unlike milk or white chocolate, dark chocolate containing 70 per cent cocoa or more is packed with flavonoids. But don’t over do it — a small square is all you need.
8. Flaxseed. Flaxseed offers cancer-preventing phytochemicals and is an excellent source of alpha linolenic acid or ALA (an omega-3 fat) and lignans, which can help prevent heart disease. It’s easy to add to foods like cereals, cookies, meatloaf and stews, and can also be used to replace eggs in recipes.
9. Garlic. There are many reasons to enjoy this potent member of the onion family, including sulphur compounds that boost the immune system and prevent many cancers. It’s also good for the heart because it can prevent blood from forming dangerous clots and can help lower cholesterol.
10. Green tea. Served hot or cold, this popular beverage contains catechins, which fight inflammation and improve blood vessel functioning. Try drinking it hot (with lemon and honey), or iced with a shot of your favourite fruit juice.
13. Oats. They have all the phytochemicals and nutrients of other whole grains, but they really shine for their beta-glucane content (which lowers bad cholesterol) and avenanthramides (which protect LDL cholesterol particles from free radicals).
14. Extra-virgin olive oil. It’s the go-to oil for its healthy monounsaturated fats, vitamin E content and phytochemicals. It’s not just for cooking — mix it up with some balsamic vinaigrette for a tasty dressing.
15. Oranges. Famous for their vitamin C, oranges also offer phytochemicals that help prevent disease. Another bonus: enjoying whole fruit instead of juice offers up fibre as well.
16. Red bell peppers. Known for their vitamin C and beta-carotene content. You’re better off eating red peppers raw or lightly cooked as overcooking can damage the vitamins.
17. Salmon and other omega-3-rich fish. No surprise, it’s the high levels of fatty acids that make these choices a mainstay in the longevity diet. Trout, Arctic char, sardines and herring are other low-mercury options to try.
