As collagen weakens, symptoms like morning stiffness, swelling after short walks, and a grinding sensation in the joints may appear. Adding kiwi to your diet can help maintain joint flexibility and slow this decline.
How to eat it:
Wash thoroughly and, if possible, eat it with the peel, where many antioxidants are found. It works well on its own, mixed with yogurt, or blended into smoothies.
Bromelain helps reduce this inflammation, allowing joints to recover more effectively.
Important note:
The pineapple core contains the highest amount of bromelain and is often thrown away.
How to eat it:
Always choose fresh pineapple, not canned. A small piece of the core blended with the flesh—preferably in the morning—is enough. Those managing blood sugar should keep portions small.

Papaya supports muscle and joint health by improving protein digestion. It contains papain, an enzyme that helps break proteins into amino acids, which are necessary for building muscles, tendons, and collagen.
In many cases, leg weakness isn’t due to low protein intake but poor absorption. Papaya helps address this while also supplying vitamin C.
