Age might be just a number, but when it comes to your nutrition post-sixty, it's more like the secret code that changes the game. According to Abigail Collen, a dietitian at Mount Sinai, one crucial amendment is bolstering your calcium intake. Why? Because this bad boy supports bone strength, fighting off the osteoporosis monster hiding under your bed.

Stock your fridge with the heavy hitters – oysters, herring, roe, perch, and rainbow trout. Dairy products and – shock horror – fortified orange juice. Julia Zumpano, a dietitian at Cleveland Clinic, suggests a freebie method too. Just step outside for a walk, because just like vampires need blood, your body needs twenty minutes of direct sunlight for vitamin D.

Age plays a villain by making your body a traitor, especially when it comes to absorbing vitamin B12. The guilty as charged? Reduced stomach acid production. Fortunately, you can deal with this treacherous act by eating more meat, eggs, dairy, fish, and some fortified grains and cereals.

You might have been advised to cut down on protein at your last family dinner, but screw that. Stuff your face with chicken, fish, eggs, Greek yogurt, and tofu whenever you can, unless you're struggling with a beast named chronic kidney disease.

And let's not forget about fiber. It's the unsung hero responsible for good digestive health. Your mission? Fill up your plate with plant-based foods like beans, non-starchy veggies, fruits, nuts, and seeds.

As for your daily habits, Zumpano shares her golden rules. They sound less of a grind and a lot more sensible like staying hydrated, following an eating schedule, avoiding food fasting games, and sneaking meaningful nourishment in every meal.

Also, avoid processed foods, wave goodbye to sugary beverages, and spank those baked goods out of your life. Basically, don't overthink it. Eat clean, work out, stay hydrated, and you're pretty much nailing it.

Stuck with your new dietary needs? Call in a dietitian or a nutritionist to plot a tactical map tailored for your daily routine.

Finally, accept it. Past sixty, you might be dancing a samba with reduced metabolic rate due to muscle mass loss. But worry not! In the battle against aging, you've got some heavy artillery – sufficient dietary protein and regular resistance training.

Go ahead, kick some serious butt as you age. You’ve got this!
