Living into our hundreds conjures up images of sci-fi movies with magic anti-aging pills and bionic organs. Turns out, the secret to living longer isn't actually a secret at all. According to the biggest study on longevity, the Grant & Glueck studies out of Harvard, making it healthily and happily to old age requires a number of lifestyle habits: not smoking, having an active social life, getting exercise, keeping a healthy weight, and eating the right foods. Although you need to maintain all these habits at once to reap the longevity benefits, there's no denying that what you eat plays a big role beyond how it affects your waistline, which is why we've rounded up these foods to live longer.

Leafy greens, like spinach, kale, arugula, mesclun, and romaine, are some of the healthiest foods on the planet. In fact, in a study conducted by William Paterson University, the top 15 nutrient-dense types of produce were all greens. These leafy greens should be the basis of a healthy diet to combat disease-causing inflammation and heart disease. People who ate at least one serving of leafy greens a day decreased their risk of death by 15%, according to a study published in Experimental Biology.

Extra virgin olive oil also contains potent antioxidants called polyphenols, which may help protect your brain. Research published in the Journal of Alzheimer's Disease found that these antioxidants have beneficial effects on learning and memory deficits, and could help reverse age-related cognitive decline.

One of the secrets to a healthy diet is getting enough fiber, which is the key to suppressing your appetite and keeping blood sugar low. Chia seeds are surprisingly full of fiber, packing an impressive 11 grams in just two tablespoons.

Chia seeds are easy to throw into yogurt or smoothies or to top your salad with.

People tend to steer clear of carb-heavy meals, like oatmeal, but this fiber-rich grain can help regulate cholesterol.

Yogurt is one of our favorite foods, especially protein-packed Greek yogurt. But the live cultures in yogurt are what will keep you alive longer.

An apple a day keeps the doctor—and the Grim Reaper—away. The healthy fiber from the skin can help prevent the onset of Type 2 diabetes; a study published in BMJ found that eating whole fruits, especially apples, can lower your risk of developing the chronic disease. Plus, apples have been shown to boost your immune system, which will help you fight off disease.

Your morning coffee habit doesn't just wake you up—it could also save your life. Research conducted by Stanford Medicine found that caffeine, like the levels found in coffee, can help fight off disease-causing chronic inflammation, which contributes to cancer, Alzheimer's, heart disease, and other life-threatening chronic illnesses. The researchers also reviewed another study published in the journal Nature Medicine and found that study participants who had the most caffeine intake had the lowest levels of inflammation.

Tea

Green tea is one of our favorite foods for weight loss; it's been shown to rev up your metabolism, squash hunger, quell stress, and shrink fat cells. In addition to keeping weight off, it also has anti-aging benefits. It can help regulate cholesterol and prevent sun damage on your skin, leading some researchers to believe it could help slow down the growth of certain cancer cells.

This hulk-hued tea is the ultimate weight loss enabler and the perfect way to boost your metabolism. That's because the tea leaves contain catechins called epigallocatechin gallate, or EGCG. A study in the Journal of Advanced Pharmaceutical Technology & Research shows that the high EGCG and polyphenol content in green tea makes it a more potent anti-inflammatory than any other tea—so drink up!

Hot peppers

If you like spicy food, you may be in luck; hot peppers have proven to extend your life. A Chinese study found that people who ate spicy food three to five days a week reduced their risk of dying by 15%. The key ingredient is the capsaicin, researchers believe; capsaicin also has anti-inflammatory properties and can rev up your metabolism. Hot sauce may be the closest thing we have to a miracle anti-aging supplement.

Salmon

A diet with fatty fish, including salmon, will help slow an aging heart. Salmon is rich in omega-3 fatty acids, which can help lower blood pressure and can help prevent heart disease. It's not just good for your heart; salmon can help protect your brain, too. Alzheimer's has been linked to inflammation, and omega-3 is a known inflammation-fighter.

Whole grains

Eschewing refined white carbohydrates, including bread, rice, and sugar, for more complex carbs like brown rice, quinoa, barley, and wheat, is known to help you lose weight. But it can also help you live longer; a review from the Harvard T.H. Chan School of Public Health found that in the 12 studies they reviewed, people who ate 70 grams of whole grains each day had a lower risk of premature death, compared to the group who ate fewer or no whole grains.

Dark chocolate

Dark chocolate (think: more than 75% cacao) is full of antioxidants, which could help stave off disease and help you live longer. It's also a powerful anti-inflammatory food; a study published in the American Journal of Clinical Nutrition found that dark chocolate can help prevent and repair cellular damage caused by inflammation because of the antioxidants flavanols.
