In 2014, I had my left hip replaced with a titanium hip joint. My blood cobalt level is now 4.4. How much can diet affect this level. I assume that I would have to consume a whole lot of vegetables to raise my blood level.

Welcome to Mayo Connect. If you have read a bit, here and elsewhere, you will have seenthat the major concerns are with metal-on-metal (MoM) hip implants, which were chromium-cobalt balls and acetabular cups (without cross-linked polymer linings) used largely between 2000 & 2010.
You can read about them here:

While there is currently some concern about metal ions from other types of hip implants, levels like yours fall into the range generally considered safe. I believe monitoring is recommended to be sure they are not rising, as this would be evidence of premature metal wear.

Do you know exactly what implant you received, and what is the composition of the femur head and the acetabular lining?
