Use of cereal bars with quinoa Chenopodium quinoa W. Consumo de barras de cereais com quinoa Chenopodium quinoa W. Quinoa is considered a pseudocereal with proteins of high biological value, carbohydrates of low glycemic index, phytosteroids, and omega-3 and 6 fatty acids that bring benefits to the human health.

The purpose of this study was to investigate the effects of quinoa on the biochemical and anthropometric profile and blood pressure in humans, parameters for measuring risk of cardiovascular diseases.

Twenty-two 18 to year-old students were treated daily for 30 days with quinoa in the form of a cereal bar. Blood samples were collected before and after 30 days of treatment to determine glycemic and biochemical profile of the group. The results indicated that quinoa had beneficial effects on part of the population studied since the levels of total cholesterol, triglycerides, and LDL-c showed reduction.

It can be concluded that the use of quinoa in diet can be considered beneficial in the prevention and treatment of risk factors related to cardiovascular diseases that are among the leading causes of death in today’s globalized world. However, further studies are needed to prove the benefits observed. Vinte e dois estudantes com 18 a 45 anos de idade foram tratados diariamente, por 30 dias, com quinoa sob a forma de barra de cereal.

The category of snacks, defined as fast foods that can be eaten between main meals, is growing significantly in relation to other types of food products PAIVA, These trends are tied to the increased search for products that are beneficial to health or that represent a reduction in risk factors for the development of future disorders, such as cardiovascular diseases SANTOS et al. Therefore, recently, there has been a search for alternatives that are easier to obtain and can act as supporting factors in the treatment of the risk indicators, such as obesity, dyslipidemia, and high blood pressure.

As a result, dietary alterations associated with economic, social and demographic changes and their effects on human health have been observed in several developing countries HOENIG et al. The increasing substitution of fresh foods rich in fibers, vitamins, and minerals for industrialized products, allied to a sedentary lifestyle favored by changes in the work structure and technological advances, represents one of the major etiological factors in obesity associated with systemic arterial hypertension, dyslipidemias, cardiovascular diseases and metabolic syndrome.

However, adequate nutrition allied to other modifications in the lifestyle contributes to the improved control of these associated risk factors preventing complications and increasing quality of life BLONDE, ; DONIN et al. Accordingly, cereal bars emerged about a decade ago and represent an alternative food that is easy to consume while simultaneously possessing functional properties SILVA et al.

Since the consumption of cereals has expanded from the breakfast table to any time of the day, these products have become an excellent vehicle for the inclusion of functional ingredients in the consumers’ diet. Some cereals and pseudocereals have been widely included in food products to meet consumer demand due to their physiological and metabolic properties. Corn, rice, potatoes, and grains such as quinoa Chenopodium quinoa W. It is an important source of proteins of high biological value, carbohydrates with low glycemic index, vitamins thiamine, riboflavin, niacin, and vitamin Eand minerals magnesium, potassium, zinc, and manganese.


It is also rich in phytosteroids such as soyomega-3, and 6 fatty acids. The literature does not report data showing the effect of quinoa on the biochemical profile of animals.

Therefore, the aim of this study was to investigate the effects of quinoa on the biochemical and anthropometric profiles and arterial blood pressure of humans based on its use in cereal bar formulations. The study population comprised twenty-two students between 18 and 45 years old, 9 males and 13 females, from different terms chosen randomly qiinua participate in the project.

Weight and stature were measured, respectively, on an electronic balance Filizola with a capacity for kg and a stadiometer SANNY with millimetric precision. The anthropometric measuring techniques presented below were based on Heyward Blood collection was performed in the same period of the day from individuals after an 8- to hour fast.

The subjects were instructed to follow a normal diet without changes during the treatment period. All individuals signed a Consent Form before participating in the study.

Cereal bars were prepared following the methodology described by Freitas and Moretti with ingredients obtained from the local market Table 1. The quinoa used was imported from Bolivia and marketed by the Vitao manufacturing company.

The agglutinating syrup was prepared in a stainless steel container to melt and dissolve the sugars, followed by the addition of pre-dissolved maltodextrin, vegetable fat, and lecithin. The cereal bars were administered daily, including weekends.


The students consumed two bars per day, at a total concentration of The data were described using Descriptive Statistics and analyzed using a Student’s t energetiacs comparing the two stages of the study. The initial collection of biochemical data revealed that The anthropometric measurements indicated that After the day treatment, it was observed significant reduction Table 2 in the cholesterol levels as well as in triglycerides and LDL-c levels Although not significant differences in glycemic index, weight, and BP were observed, when these parameters were evaluated in terms of percentage data not shownit was observed that Based on the findings, a parallel was drawn between the genders male and female and the stage of treatment pre- and post-treatmentas indicated in Table 3.

A significant decrease was found in total cholesterol among the women but not among the men studied. However, the latter showed a statistical tendency for the reduction in this index. Both women and men showed a significant decrease in the LDL-c energeticaas. Post-treatment glucose levels were lowered significantly in men, but not in women.

For the hepatic enzymes, no significant difference was found in ALT alanine transaminase values in either sex, but both sexes showed a decrease in AST aspartate transaminase values.

Women barrqs significantly barrsa post-treatment concentrations of triglycerides and urea, which was not the case among men. Neither sex showed a significant difference ds pre- and post-treatment blood pressure or body weight. Some studies have suggested that the vegetables and cereals widely consumed by the population have active compounds that were proven to have physiological and metabolic properties.

These studies include soybeans, eggplant, and oats, which have been exhaustively investigated with respect to their brras effects on dyslipidemias. Other studies have focused on plants such as Glycine Max L. The ingestion of dietary grains and fibers has been associated with diminished risk for obesity and diabetes QI et al. The results obtained in quinuua present study corroborate the data reported in the literature indicating that quinoa can be used in plasma lipids and glycemic control.

There are plants that may contribute to the reduction of the body mass index BMI and show beneficial effects on the control of arterial blood pressure, such as Matico Piper angustifolium R. In this study, after 30 days using quinoa cereal bar, After 30 days, the use of quinoa did not lead to hepatic or kidney damages, as observed by the AST, ALT and urea levels. These substances have shown hypocholesterolemic effects and increased postprandial sensitivity and release of plasma insulin KWON et al.


Abugoch James found antioxidants capacity compounds such as polyphenols, phytosterols, and flavonoids in grains of quinoa. These substances may be related with the effects of reduction in plasma lipids and glucose levels in the individuals tested. Matsuo demonstrated that the use of this grain can also be beneficial for increasing the production of liver antioxidant enzymes.

Wuinua increase of these enzymes is related with the reduction of harmful effects caused by free radicals on the quinau body, which it leads to a reduced endothelial alterations endothelial dysfunction and decreased oxidation of LDL-c molecules, and hence, reduces the risks for vascular diseases ADLER et al. Braras present study also bargas that this pseudocereal positively influenced the various risk factors for the development of diabetes and vascular diseases, which are the most frequent diseases today.

Based on the data obtained in this study, it can be concluded that the use of quinoa in the composition of a cereal bar may help reduce risk factors related to cardiovascular diseases that are among the major causes of energetiacs in today’s globalized world although further studies are needed to prove the benefits observed.
