3 days seems a bit right for the coconut bread. You can make a double loaf if you wanted that will last about 6 days (double the recipe). Use baking soda or baking powder to make it a big more fluffy.
I’d research some food safety stuff if you are concerned about meat lasting over time. It should be ok as long as its been in the fridge. There are some basic guidelines to follow but food needs to be kept at certain temperatures.
