Disavow those bad links and seek to increase the number of good reputable links you have. I checked out the url, you have a great looking site!
I bet you could relatively easily get some influential health food bloggers or magazine editors to write about your products. Food's relatively easy to get links for because you can send out 1000s of samples to influencers at a very tiny cost. This is a time honored PR method that still applies in the digital age. If people like the food and the message, they will many times write about it. I'd suggest approaching those types of influencers, telling them the story of your brand and potentially sampling them. If they like your product, chances are they will write about it and you might get some great backlinks out of it. Key is you cannot pay for those links, they must be freely given because the editor/blogger/writer likes your product and/or brand. Best of luck!
