oh god my eyes, too much brightness. Go find a site you like and copy their colors/theme. If you keep this them then pick one color and make it bright, use it as a highlight and make the other colors more muted. Your link color does not stand out on the yellow. The background green gradient looks very bad, just change it to black. Change the logo to white. Use a san-serif font everywhere. I like the simplicity but the colors need help.
Well! I found them too bright from my liking. I understand that food industry sites require bright color but instead you could opt for an image gallery which i found missing, is what i believe very important. Also include your product ad or video.
