Or perhaps you are someone whose parents scrupulously followed government nutrition recommendations when they raised you and your siblings, and you and your siblings continued following those recommendations for yourselves as adults, and for your children.

You and and your siblings all turned out fat and diabetic, and you've all got fat children, and you've concluded that maybe some of those government recommendations were driven more by politics and preservation of profit than by science.

So now you are inclined to be skeptical of government recommendations, especially where the recommended actions benefit someone with a big lobbying apparatus.
