It’s first important to note that this eating plan is not intended to be a long-term solution, or something you should follow for an extended period of time. Rather, the elimination diet should simply be used to determine which foods are causing you discomfort, so you can remove those ingredients from your life, rather than nix entire food groups from your eating plan.
You should also be aware that this is a restrictive diet by nature, and may lead to nutrient deficiencies in the future if followed for longer durations.
The process of following an elimination diet is relatively simple. “You want to remove all the foods that you are going to remove at the same time, not one by one. This is necessary to remove all the possible instigating foods for the same period of time,” explains integrative immunologist Heather Moday, M.D.. Then, generally two to six weeks later, “you want to re-introduce one food at a time every 36 to 48 hours to assess whether you have a negative reaction,” she says.
Of course you should be consulting with a healthcare professional before making any major changes to your diet, so they can guide you on which foods to keep your eye on, as well as which ingredients you can consume in the meantime to ensure you’re still adequately nourishing your body.
