Digestive disorders can be difficult to diagnose. Even if a specific disorder is suspected, such as wheat or lactose intolerance, it can be difficult for a person to cut that ingredient from their diets for long enough to ascertain the effect it has on their digestive health. Checking hundreds or thousands
of food labels over a period of several months is difficult.
This service will deliver a crate of food once or twice a week to a person's house and / or workplace. The crate contains everything the person will need to eat for a week, and includes enough quantity and variety for the subject to not desire food from any other source. It includes ready meals, pre-prepared lunch-boxes, snacks and raw ingredients for home cooking.
The ingredients are carefully varied each week or over several weeks, to test for various digestive pathologies. The patient is not informed what substance is being tested, if any, and keeps a log log recording bloatedness, cramps, bristol scale, etc. The data are fed into a computer or returned by post.
After several months, a report is produced detailing the substances most suspected of causing an adverse reaction in the subject.
Of course, there's no reason why a person couldn't do this all themselves, or under instruction from a GP or nutritionist, or even at some wacky detox camp, but the comparative simplicity (no label-reading, medical research or number crunching required) and low cost of this service (no specialist consultation required; just pay for food you'd need to eat anyway) would give it an advantage.
Having successfully diagnosed its customers, the company will then have a captive audience for its follow-up product of a subscription of overpriced specialist health foods delivered weekly, for life.
Alternatively, this could be a collaborative community project which maintains an assortment of pre-prepared shopping baskets ready to checkout at major online food retailers, and some free software for analysing the results.
