Whether it's discovering that first gray hair in the mirror or finding your knees aching after your usual workout, the seemingly sudden onset of the aging process can surprise anyone. Aging affects virtually every part of our bodies, both internal and external, and while plastic surgery and good genes can keep you from looking your age for a while, they can't fend off Father Time forever.
However, for those of us who want to be healthy and active when our peers are getting old and gray, there's still hope. Our 50 fountain-of-youth secrets will keep you getting carded well into middle age and will keep your neighbors gossiping about where you're hiding the Dorian Gray-esque portrait of yourself. Even if you're still young, it's never too early to start focusing on your full-body health by ditching the 30 Foods You Should Never Eat After Age 30.
Ditch the Dairy

Considering that researchers estimate that up to 75 percent of the adult population has a decreased ability to digest dairy, it's shocking how much of the stuff we're still eating. If you want to stay youthful forever, you may want to give all that cheese in your fridge a heave-ho; not only is dairy a major source of inflammation, researchers at Japan's Kyushu university have linked dairy consumption to an increased risk of Alzheimer's disease.
Enjoy Some Salmon

Swapping out high-calorie protein sources, like beef, in favor of salmon might just help you retain that youthful glow for longer. Researchers at Purdue University have found that the omega-3 fatty acids that are plentiful in fish like salmon can increase your body's production of collagen, keeping you looking line-free and lovely.
Hit the Gym

Logging some extra hours at the gym now can make a major difference when it comes to aging. According to a study published in Preventive Medicine, adults who were regular exercisers for 30 minutes a day had cells that were a jaw-dropping 9 years younger than their sedentary counterparts.
Cut Calories

That diet you're on may seem punishing, but cutting those calories now may make a big difference in the long run. Researchers at St. Louis University have discovered that slashing your caloric intake can decrease your body's production of T3, a thyroid hormone that can cause you to age more quickly. Just don't dip below 1,200 calories a day or you could slow your metabolism and deplete essential fat stores that can keep you looking youthful.
Cook Up Some Collard Greens

Cooking up a batch of collard greens to enjoy alongside your favorite whole grains and lean proteins could help your brain stay as young as you feel. The results of a study published inAlzheimer's & Dementia reveal that individuals who consumed the most leafy greens significantly reduced their risk of developing Alzheimer's while limiting other markers of brain aging, too.

Grab a Cup of Joe
If your most consistent long-term relationship is the one you have with your morning coffee, you're in luck. A study published in Circulation in 2015 reveals that individuals who drank between 3 and 5 cups of coffee each day were approximately 15 percent less likely to die prematurely than those who stayed away from the stuff.
Increase Your Intake of Healthy Carbs
While we definitely don't need all the sugar and white flour that makes its way onto most menus, healthy carbs can make a major difference in terms of your longevity. Researchers at Harvard's T.H. Chan School of Public Health found that consuming 3 or more servings of whole grains each day reduced the overall mortality risk by 20 percent.
Add Some Cinnamon to Your Food

Sprinkling some cinnamon on your coffee or into your favorite baked goods can make a major difference when it comes to how your brain ages. According to research published in PLoS One, animals given cinnamon supplementation had reduced rates of cognitive decline than those who were given a placebo.
Enjoy Some Guava For Dessert

Add some variety to your fruit selection by making guava part of your regular routine. Guava is a good source of antioxidant lycopene, which has been linked to improved memory retention and a reduced risk of degenerative disease, according to researchers at the University Institute of Pharmaceutical Sciences.
Grill Up Some Tuna Steaks

Instead of tossing a ribeye on the grill, make tuna steaks your go-to protein and you'll be looking younger in no time. According to researchers at Purdue University, the omega-3s found in tuna are a powerhouse when it comes to skin aging, thanks to their ability to spur the production of new collagen-forming cells.

Switch to Whole-Grain Bread

Grab some whole grain bread instead of a wimpy white slice and you'll be setting back the clock both inside and out. Research conducted at the Linus Pauling Institute at the University of Oregon have discovered that manganese-rich whole grains can boost collagen and elastin production, keeping wrinkles at bay. Even better, research published in the Archives of Internal Medicine in 2011 reveals that people who swapped out refined carbs for whole grains slashed their risk of overall mortality by a whopping 22 percent.
Load Up on Probiotics
Getting your gut health in order can keep you looking and feeling youthful and healthy. Researchers at Sweden's Lund University have linked healthy gut bacteria to a decreased risk of developing Alzheimer's, so there's no time like the present to make probiotic foods, like sauerkraut, yogurt, and kimchi part of your regular menu.
Get Your Blood Pressure Under Control

Getting your blood pressure under control is the first step toward a longer, healthier life and one of the easiest ways to reverse the aging process. Not only can hypertension increase your risk of premature death and cause swelling that can age you externally, a study published in Nature Reviews Neurology reveals that high blood pressure can cause rapid brain aging by shrinking the size of the hippocampus.
Add Flax to Your Food

Sprinkling a little flaxseed into your favorite smoothie might just be the easiest way to fend off the ravages of time. This high-fiber addition to your diet can not only improve the health of your gut bacteria, thus reducing your Alzheimer's risk, the omega-3s found in flaxseed can prompt your body to create new collagen cells, making your skin smooth and line-free.
Snack on Some Sweet Potatoes
Instead of regular French fries, make some oven-baked sweet potato fries and you'll be slowing down the aging process with every bite. Sweet potatoes are a good source of manganese, which can boost collagen and elastin production and keep your skin wrinkle-free. Sweet potatoes are also loaded with beta-carotene, which research published in Dermato Endocrinology has linked to reduced skin aging. Researchers at the France's Bichat University of Medicine have even found that beta-carotene can reduce the loss of lung function, even among even among heavy smokers.

Add Some Pumpkin Seeds to Your Menu
Don't ditch the guts of that pumpkin when you're done carving your Jack-O'-Lantern this year; instead, roast them up and fight aging in the process. Pumpkin seeds are a good source of zinc, which research published in Genes & Nutrition has linked to reduced rates of dementia. A study published in the Journal of Nutritional Biochemistry has also linked zinc consumption to better immune health, meaning it may help you stave off chronic diseases, too.
Whip Up a PB and J

Adding some healthy fats, like peanuts, to your menu might just be the key to looking and feeling younger as you age. Peanuts are a good source of monounsaturated fats, which have been linked to lower rates of heart disease, and they pack a healthy helping of vitamin C, which can improve your immune health while increasing your body's natural collagen production. Find out which peanut butter should earn a spot in your sandwich by discovering our list of the 36 Top Peanut Butters—Ranked!!
Take the Stairs

One simple activity can both save time and save your life: taking the stairs.

Spice Up Your Food

Keeping things caliente in the kitchen is one of the easiest ways to ensure a long, healthy life. Not only are spicy foods a rich source of metabolism-boosting capsaicin, a study conducted on 490,000 adults in China reveals that those who enjoyed spicy foods at least twice a week cut their risk of premature death by 10 percent.
Train For a Marathon

Giving yourself some concrete fitness goals, like training for a marathon can do more than just give you something to look forward to, it can also help you live longer. Research published in Circulation reveals that that 50-somethings who exercised vigorously on a regular basis were biologically younger than those who opted for a more sedentary lifestyle.
Learn to Forgive
You don't have to forget the hurtful things that have happened to you, but learning to forgive might just be the key to staying young forever. Research published in the Journal of Behavioral Medicine reveals that, among 1500 American adults over age 66, those who were less likely to forgive or gave conditional forgiveness were significantly more likely to die prematurely than their more forgiving counterparts.
Go Vegetarian
Going meatless, whether in the short-term or forever, can seriously prolong your life. The results of a study published in JAMA Internal Medicine reveal that individuals who shunned meat but occasionally ate fish had the lowest mortality rates. The omega-3s in fish can also decrease your risk of both heart disease and aging skin, so there's no better time to add some seafood to your menu.
Ditch the Take-Out

Saving money and living longer can be easily accomplished with one easy action: cooking for yourself. Researchers at Cambridge University found that adults who prepared their own meals at least five times each week were a shocking 47 percent less likely to die in the next ten years than take-out devotees.

Cook With Olive Oil

Swap out that vegetable oil for extra virgin olive oil and you'll be getting younger every time you hit the kitchen. A study published in the London journal Nutrition & Metabolism found that substituting EVOO in place of inflammatory vegetable oils can increase levels of HDL, the "good" cholesterol, and help decrease blood pressure.
Laugh

They say humor is the best medicine, and it might just be, at least as far as longevity is concerned. Researchers at Yeshiva University's Albert Einstein College of Medicine found that the common thread among a group of 243 people who'd hit the 100-year mark was a love for laughter.
Get Some Altitude

Good news, mountain dwellers: your high-altitude home might just extend your life. Research conducted by Harvard University and the University of Colorado found that residents of high-altitude locations had longer life expectancies than those closer to sea level.

Researchers from Harvard Medical School found that resveratrol, an antioxidant pigment in red fruits, can slow down the aging process, and multiple studies suggest that it can reduce your fat stores, too.
Get Psyched About Getting Older

Having a positive outlook on the aging process might just keep you young forever. A study published in the Journal of Personality and Social Psychology reveals that adults who thought of getting older as a positive thing lived 7.5 years longer than those who were soured on the subject. Pessimism is just one problem for your health —the 31 Things You Did Today to Slow Your Metabolism can keep you just as sick.
Start Saving

Money can't buy happiness, but it might just buy you more time on earth. Researchers at Stanford University have found that those with the highest income lived an average of 15 years longer than those with the lowest. While this likely has a lot to do with their access to healthy food and better medical care, having some money in the bank certainly can do a lot to improve your outlook on life, too.
Add Some Watermelon to Your Menu

Cool down this summer with some watermelon and you might just slow down the aging process along the way.

Take a Vacation
Research suggests that more than half of adults in the United States don't take their allotted vacation time, and that habit might just be sending them to an early grave.
