Nope. Those blood sugars are normal. Why eat? Unless you're really, really hungry of course... Quite a few here practice intermittent fasting and don't eat for say, 16 hours or 18 hours straight. Is there any specific reason why you think you should eat when you're seeing nice and normal fives?
That's assuming you're a Type 2 though? If you're on insulin you might feel more comfortable eating, but otherwise... Nah.
