[Nutritional knowledge and consumption frequency of foods--a case study]

Area of Science:

• Nutrition Science
• Consumer Behavior Studies
• Public Health Research

Background:

• Understanding the link between nutritional knowledge and dietary habits is crucial for public health initiatives.
• Previous research indicates a general positive association, but specific consumer groups require targeted investigation.
• Uruguayan dietary patterns and nutritional awareness levels present a unique area for study.

Purpose of the Study:

• To investigate the relationship between nutritional knowledge and food consumption patterns among Uruguayan consumers.
• To identify specific areas of nutritional knowledge gaps within the studied population.
• To determine if higher nutritional knowledge influences the frequency of consuming preferred food types.

Main Methods:

• Utilized a locally adapted version of the General Nutrition Knowledge Questionnaire.
• Administered a food consumption survey covering 39 food groups to 270 participants.
• Employed Cluster Analysis to group participants based on nutritional knowledge levels.

Main Results:

• Two distinct clusters were identified: Cluster 1 (73.6% correct answers, n=177) and Cluster 2 (52.9% correct answers, n=93).
• Cluster 1 participants were significantly older and had higher educational attainment (p < 0.05).
• Poor knowledge was noted regarding recommended fruit/vegetable intake and nutrient caloric content.
• Higher nutritional knowledge positively correlated with increased consumption of fruits, vegetables, and low-fat foods, and decreased intake of high-fat/sugar foods.

Conclusions:

• Nutritional knowledge significantly influences food preferences and consumption frequency in Uruguayan consumers.
• Targeted nutrition education is needed, particularly in areas like fruit/vegetable recommendations and caloric content.
• Interventions promoting nutritional literacy may lead to improved dietary choices and public health outcomes.
