When eating real food we can find ourselves ‘critiquing’ other peoples food choices. I know myself I am guilty of always looking at what other people are buying when at the grocery store, and I always feel proud of my choices.
On the other side, something I struggle with is trying to help the people who are close to me make better food choices, and if you have tried this yourself you can attest that it is not always an easy sell.
