Nutrition Assessment for Sport and Life

What is Nutrition Assessment?

crowd of young people

The original term was used by a sub-committee of the League of Nations (1932) referring to a set of medical tasks to determine the nutritional status of a population (Gibson, 2005). After 1976 (Bistrian & Blackburn et al), it became a standardized, hospital-based set of tools to predict nutrition and health outcomes in individual patients with post-op complications, trauma or malnutrition.  

In 1996, Theresa Schneider RD decided to take assessment tools out of the hospital to assess the health of athletes, those with chronic diseases and corporate executives.  Today a nutrition assessment includes computerized food intake analysis, clinical nutrition body composition assessment (bioelectrical impedance), laboratory blood test results if applicable, nutrigenomix, anthropometrics, review of medications, lifestyle and  fitness indicators.  Whether your goal is to improve your athletic performance, or you want to make a nutrition lifestyle choice or you want to better manage your medical condition can help you succeed.

Because so few Ontarians have OHIP insurance coverage for the services of a registered dietitian, Nutrition Assessment is working to assist people to begin to 'self-assess' their nutritional status. From an understanding of their present nutritional health, they may ask the right question to the right health professional or fitness expert. Nutrition Assessment's philosophy is to provide an advanced thorough review of a client's nutritional requirements, fitness and lifestyle and social circumstances before writing diets or recommending supplements.

This service allows you to adjust what you eat according to your genetic ability to utilize some nutrients in your diet: gluten, saturated fat, Omega 3 oil, fibre, caffeine, sodium, folate and Vitamin C.

The Nutrition Assessment Clinic works in cooperation with your MD, physiotherapist, athletic therapist, kinesiologist, occupational therapist, psychologist, coach, conditioning coach or personal trainer to build an effective program for you.

The Clinic has selected clinical nutrition software along with client information to assess nutrient needs. Bioimpedance body composition analysis, computerized food intake analysis software, a measure of basal metabolic rate, medication history, food and drug interaction and laboratory tests are used. In treatment plans the clinic uses individual meal plans based on a clients learning style. Behaviour management strategies may be needed to help some clients reach their goals. Clients are assisted with ideas for eating out, travel, shopping lists and recipes. To begin the process you may download a free food diary and exercise diary. If you need help with this contact us for a password to enter the information on computer analysis software which can be sent to a Registered Dietitian at who will contact you to go over your intake analysis and provide advice. If you are in Kingston or Southeastern Ontario, come to the Nutrition Assessment Clinic for consultation.
