Abstract
The intake of processed foods of high calorie density is associated with weight gain and changes in lipid and cardiovascular metabolism. However, the modification of eating habits is possible due to, among other factors, information provided to patients about the foods/nutrients ingested. The present investigation observed the impact of nutritional counseling on anthropometric and on biochemical indicators in a blind controlled study. Therefore, a single investigator counseled obese workers divided into three groups over a period of 42 days. A control group (CG) received no counseling. GLi50 received 60 g/d linseed and 50% of the energy supply as carbohydrates; GRi50 received 60 g/d raw ground rice and 50% of the energy supply as carbohydrates, and GLi32 received 60 g/d linseed and 32% of the energy supply as carbohydrates. A total of 118 vo- lunteers started the protocol and 52 completed it. The most consumed foods were rice, beans, bread, manioc flour, soy oil, red meat, and eggs. CG did not show any modifications. The remaining groups, regardless of diet composition, showed a reduction of anthropometric measurements, be- sides reduced glycemia, cholesterolemia, triglycerides and insulinemia, as well as reduced peripheral resistance to the action of insulin. More important than supplementation or the proportion of carbohydrates ingested, nutritional coun- seling was the common factor for adequacy of energy intake, weight loss and improved biochemical indicators. Nutrition counseling can be a viable and economically strategy for helping patients with life style diseases.
Highlights
The intake of processed foods of high calorie density is associated with weight gain and changes in lipid and cardiovascular metabolism [1,2,3,4]
The food intake reported at the beginning of the study reflects the usual intake of each participant and the final values reflect the result of nutritional counseling
The final modification was the result of the 42 days of nutrition counseling to which the volunteers were submitted
Summary
The intake of processed foods of high calorie density is associated with weight gain and changes in lipid and cardiovascular metabolism [1,2,3,4]. The modification of eating habits is influenced, among other factors, by information/counseling provided to patients about the foods/nutrients ingested. This process is based on constant and active counseling, with repetition and reinforcement of modifiable food/nutrient characteristics. Counseling depends on patient’s disease, on preventive and/or curative aspects, on the cognitive level of the patient and on the availability and technical skill of the counselor. Control group subjects do not receive any counseling/information [5]. The evaluation of food intake and later nutrition counseling are important as a contribution to treatment and for the modification of eating habits, preventing the recurrence of nutritional disorders [6]
