Slows down my site

Hi! I love you theme! It’s by far the best one out there that I’ve found! Thanks! I noticed that Pinboard items came up a few times when I run PageSpeed Insights (saw it in “Remove Render Blocking Javascript,” “Optimize CSS Delivery,” and “Optimize Images” sections. Any suggestions for fixing that?

My website is https://www.GreatFoodLifestyle.com.

Thanks.
