One of the most encouraging studies to come out recently concerns the dramatically improved lung function of people who’ve recently stopped smoking, especially those who like eating tomatoes and apples. The research, which appeared in the December 2017 issue of the European Respiratory Journal,1 shows that when former smokers increase their intake of these two foods — essentially making them their new habit — the decreased capacity of their lung function begins to lessen, and their chances for restored lung function is increased.
