(Universidade Federal do Pará, 2024-02-29) PALHETA, Gredany Rodrigues; HERRERA, Raírys Cravo; http://lattes.cnpq.br/215377919730650; HTTPS://ORCID.ORG/0000-0002-9699-8359; REIS, Alisson Rodrigo Souza; http://lattes.cnpq.br/7258026642139407; https://orcid.org/0000-0001-7182-4814
Unconventional food plants (UFP) are a group of edible and medicinal species not commercialized on a large scale, including leaves, flowers, fruits, roots, among other parts. Its origin is associated with traditional people who passed on their knowledge to family members. Given the diverse Brazilian flora, especially Amazonian species, there are still few scientific reports about these plants. Therefore, it is necessary to apply new methodologies for taxonomic identification, presence of substances and nutritional profile of edible plants. Because of this, the work aimed to diagnose the scientific production of non-conventional food plants and anatomically and nutritionally characterize the caapeba-amazônica leaf (Piper peltatum L.), contributing to scientific knowledge of the Amazonian flora. For scientometrics, the descriptors “Plantas alimentícias não convencionais” were used in Google Scholar and “Unconventional Food Plant*” in Scopus and Web of Science. For data visualization, R language was used by the Bibliometrix package and the Publish or Perish software. Astra Blue and Basic Fuchsin reagents were added to the anatomical sections of the leaf and Toluidine Blue, Ferric Chloride, Lugol and Sudam III were added for histochemistry. The Nutritional characterization was determined by analyzes of Moisture, Water Activity, Ph, TTA, TSS, Ashes, Lipids, proteins, carbohydrates and antioxidant profile. In the results, an increase in publications about UFP was observed and the theme has been published in journals with a high Qualis stratum. Related keywords indicate experimental studies as relevant themes for publication. The caapeba-amazônica is a species present in UFP articles although little quoted and studied. The anatomical characteristics of the P. peltatum leaf are consistent with the piperaceae family. In its histochemical test, the presence of lipids, phenolic compounds, starch and cellulose was observed. From the physiochemical results, it was observed to be perishable and should be stored in refrigeration. It is a source of minerals, carbohydrates, lipids and proteins, in addition to being an antioxidant. It is important to maintain new studies to contribute to the knowledge of UFP species, including Amazonian ones, such as P. peltatum, which presents substances with medicinal and food properties similar to other UFP hardwoods. Its consumption depends on the central vein of the leaf being removed, softened by cooking and similar culinary preparation of the cabbage leaf. It is a food and nutrient alternative, including for individuals affected by food insecurity. Its consumption favors agroecology and conservation of Amazonian biodiversity.

Diabetes is a chronic condition that is related to an insufficient production of insulin or an occasional deficient insulin production is diabetes in glycemic metabolism. Type 1 Diabetes Mellitus (T1D) predominantly consists of an injury to the body's own insulin-producing cells; in this case, most of them are those planned during childhood and childhood insulin to survive. The treatment of T1D involves insulin therapy, food education and physical activity, and progress has been made. Diabetes education programs are essential tools for improving metabolic control and patient inclusion in their treatment. Therefore, the objective of this study is the elaboration of a nutritional education booklet for people living with type 1 diabetes mellitus, in order to assist in the treatment. For this, educational material such as a booklet on nutrition education for people with type 1 diabetes mellitus was prepared. Through a methodological development research with a qualitative approach. The approach was structured in two stages: the first stage was the bibliographic survey that took place between the months of September 2021 to July 2022, in the databases and virtual libraries LILACS, SciELO, MEDLINE, and PUBMED, 7 relevant references were added to the topic addressed in the booklet and 5 most recent guidelines and positions from the Brazilian Society of Diabetes seeking references with a high level of scientific evidence. The second stage consisted in the elaboration of the booklet, based on the scientific content obtained through the previous stage. The material was produced using an easy-tounderstand language and objective images. Comprising information about diet in T1D, carbohydrate counting strategies, elaboration of tables in the identification of food groups in the search to offer autonomy and information about food in T1D. And after the preparation of the material, the objective is to validate it, through considerations of selected judges with expertise in the subject.

Composição química e valor nutricional para grandes herbívoros das folhas e frutos de Aninga (Montrichardia linifera, Araceae)
(Instituto Nacional de Pesquisas da Amazônia, 2010-12) AMARANTE, Cristine Bastos do; MÜLLER, Regina Celi Sarkis; DANTAS, Kelly das Graças Fernandes; ALVES, Claudio Nahum; MÜLLER, Adolfo Henrique; PALHETA, Dulcidéia da Conceição
The aninga (Montrichardia linifera, Araceae) is often found in the floodplain ecosystems of the Amazon and is the natural diet of animals such as manatees, turtles, fish, buffalo and cattle. Aiming to contribute to the chemical knowledge and nutritional value of this plant, leaves and fruits of M. linifera were collected on the banks of the Guama and Maratauira rivers, Para State, Brazil. We determined the moisture content, ash mineral composition, lipids, protein, fiber, carbohydrate and caloric value of the fruits and leaves. The mineral composition (Ca, Mg, Cu, Fe, Zn and Mn) was obtained by flame atomic absorption spectrometry. The leaves and the fruits of M. linifera had caloric values of 289.75 kcal and 355.12 kcal, respectively; and a low protein concentration, 0.44% for leaves and 0.24% for fruits. Manganese concentrations were 3279.46 mg kg-1 for leaves and 18151.53 mg kg-1 for fruits. These Mn concentrations are considered toxic, as they exceed the maximum tolerable for the ruminants (1000 mg kg-1). The M. linifera has the capacity to absorb and bioaccumulate large amounts of Ca, Mg and Mn in the soil, which makes it inappropriate for exclusive use as food for turtles, cattle and buffaloes, requiring more studies for its application as part of the diet.

Protocolo nutricional no Diabetes Mellitus Tipo 2
(Universidade Federal do Pará, 2022-08-29) PALHETA, Rayelly Cíntia Ataíde; GOMES, Daniela Lopes; http://lattes.cnpq.br/0014255351015569; FELÍCIO, João Soares; http://lattes.cnpq.br/8482132737976863
Type 2 diabetes mellitus (T2DM) is a disease with high prevalence worldwide, representing about 90 to 95% of all diabetes mellitus (DM) cases, resulting from increased peripheral insulin resistance associated with a deficient insulin secretion, which may remain undiagnosed for years. Nutritional care in T2DM is essential in the treatment of the disease, being able to improve glycemic control and to reduce glycated hemoglobin in a range of 1% to 2%. Therefore, it is essential to know nutritional strategies to patients with diabetes, in order to reach an adequate glycemic control through individualized treatment. Thus, this work objectives to develop a nutritional protocol based on a rapid review in Pubmed and LILACS databases, searching for up-to-date references with a high level of scientific evidence, in addition to the guidelines of the main scientific national and international diabetes societies. We also rely on the authors' clinical experience and publications on nutritional therapy in T2DM, in order to create didactic and objective flowcharts for glycemic, lipid and blood pressure control, as well as for weight loss in T2DM, which aim to help health professionals in the approaching of these patients, as for the primary health care scenarios, as well as for the secondary and tertiary levels.
