Should I see a nutritionist or stick to dietary guidelines?

We may all be made of flesh and blood, but each one of us has a body with unique differences. These varying individual distinctions can call for custom measures when it comes to needs for health. For these reasons good clinicians can accept established dietary guidelines as a general route for a population to make sensible eating choices, but, when appropriate, offer a tailored alternative to provide best results for a patient.

A suitable deviance from normal recommendations, for example, may be to take milk and cheese off the menu for patients of Native American and African ancestry. Lactose intolerance has been found by Cambridge researchers to affect these populations indiscriminately, which should lead clinicians to diverge from the US Department of Agriculture’s guidelines of dairy intake when caring for such affected patients (Scrimshaw & Murray, 1988).

For others increasing dietary intake of dairy may be useful. An athletic patient seeking nutritional advice may find herself or himself encouraged to supplement with protein from dairy whey directly after exercise since Australian researchers have just found that this practice may speed recovery of muscle (Buckley et al., 2008).

Customization of diet should not be limited to genetic and other physical variations in patients. The clinician who discovers a four-year-old girl’s inclination to refuse vegetables may recommend her concerned parents try a more-likeable chewable vitamin in place.

The examples given suggest person-centered care may be better for all. A community has benefited, however, from a fixed norm developed by public policy. Guidelines should not be considered as strict, but should help the grocery store and restaurant offer options while sensitive to the health of customers as well as help the lay person make smart daily food choices.
