What to do

Get medical intervention as needed; eliminate food

Identify whether the symptoms are from food you just ate or food you ate several days prior by logging your food and the occurrence of symptoms.* Once identified, eliminate food

If the symptom is caused by the lack of an enzyme such as lactase (which digests lactose), take a focused or broad-spectrum digestive enzyme supplement with the food. If tolerated, food can be eaten. If not, eliminate food.

*If you are using the MyBestBody App, log your food and track your symptoms in Track My Progress. When symptoms occur, check the foods you ate within three days to establish linkages.
Imagine the freedom of having absolute confidence in knowing that
what you eat is right in every way to look and feel your healthiest for life...
