Reduce or avoid foods that harm the prostate. You may be surprised at how many common foods irritate the prostate and can contribute to a rise in PSA levels and an enlarged prostate. Here are some of the foods and beverages that fall into this category: 1  Foods that contain acrylamide, such as French fries and potato chips (the two biggest offenders) and doughnuts. 2  Foods rich in saturated fats. 3  Excess alcohol. 4  Nonfermented soy products such as tofu and edamame, which can raise estrogen levels. 5  Microwave popcorn.
Usually, small birds like lovebirds, canaries, and parakeets live six years or older, cockatiels about 12 years, and amazons, as well as macaws and cockatoos, 40 years or more.
Every bird is different in make up and of course their diet and external environment plays a huge part in how long they live. But I would say your parakeet lived out it's average life span. The lifespan of Parakeets is 8-10 years. You must have given given him a wonderful life to have made it that far. I have heard that accidents take more lives than the average lifespan of a parrot and many never make it to 6 years old due to accidental death.
