Welcome to Greyvenstein Dietitians, Rayton



At Greyvenstein Dietitians and Associates you will find not only all relevant professional services based on internationally accepted evidence, but also building personal relationships.

We understand appreciate the diverse South African cultural makeup and the nutritional problems that occurs within this makeup. Our Dietitians have hospital level clinical experience, and exposure to a wide range of eating disorders and diseases that require specialized nutritional intervention. We are equipped to assist with nutritional support for optimal outcomes for our clients. 


Professional nutritional support is a multiphased approach, taking into consideration every clients personal preferences. The first phase is to take anthropometric (body composition) measurements including:


Waist Circumference

Hip Circumference

% Hydration

% Bone Mass

% Muscle Mass

% Fat Composition

All these measurements are taken into consideration to make an overall conclusion, and identify possible risk factors.

If the patient has any previous laboratory tests available, the patient should bring this along or send it through electronically prior to consultation. This will assist with identifying possible deficiencies or areas where nutritional intervention can improve the over all health of a client. If no previous blood results are available, the client can on request be referred to the nearest pathology laboratory where blood can be drawn and analyzed. Dietitians are trained to interpret blood results, and assist with nutritional intervention via healthy options, to avoid progression of certain diseases or conditions.

The consulting Dietitian will also conduct a clinical assessment of the client to assess any deficiencies. There is overwhelming evidence regarding clinical signs that may indicate possible markers for certain conditions where nutritional intervention has significant positive effects. Trained in the hospital setup to recognize these signs, our dietitians clinically assess the nutritional status of the client.

Dietitians need to make a nutritional diagnosis of any client they see to be able to prescribe individualized diet plans. It is therefore a critical part of any consultation that the dietitian compiles a comprehensive diet history. The diet history aids in the conclusion of the nutritional diagnosis. The diet history can be done in various forms, depending on which approach suit the client best as well as taking into consideration that the nutritional diagnosis requires all the possible information for correct conclusions.


Nutrition should be seen in its complexity – it is much more than just food.

Nutrition includes everything that the body needs for its daily energy requirements. Assistance and guidance is given on fluids (anything you drink), supplements, and everything associated with daily intake. Because there is so much conflicting information and advice on quick fixes in circulation, we also look at what the clinical evidence say regarding quick fixes, and what the long terms goals and outcomes are that can be expected.
