“…Other important micro-minerals to human health such as Cu, Fe, and Mn are present in trace amounts (0.04% of ash). Similarly, the presence of toxic elements such as Pb, Ba, Al, Li, and Be is in trace amounts, which does not compromise this food (0.22% of ash content) [32,67], and the elements are all derived from chicken feet.…”

In this research, products with high quality were obtained from natural sources. The sensorial qualities, chemical characterization, and physical properties of gelatin extracted from chicken feet were compared with commercial gelatins. The extraction process was performed using acetic acid on a concentration ranging from 0.318% to 3.682%, processing time between 1.0 h and 8.4 h and extraction temperature between 43.3 °C and 76.8 °C. After the end of each assay, the yield was measured. Results showed that, under the best conditions, the collagen extraction yield was above 8%, and comprised 78.525 g/100 g of protein. Collagen analyzed by ICP-MS was composed of 99.44% of macro-minerals that are of great importance to human health. ATR-FTIR analysis showed that approximately 70.90% of the total protein from chicken feet is collagen, whereas, in commercial gelatin, only 30.31% is collagen. When comparing chicken gelatin with commercial gelatin, most sensory attributes were similar and chicken gelatin gained acceptance by more than 80% of the consumers. Additionally, the collagen films obtained from chicken feet and swine showed water absorption, odors, and texture characteristics similar to commercial material, such as latex and celofane. Consequently, due to its similarity to human skin, it is possible to apply it as a biocurative.

“…The use of collagen can be used in the prevention and/or treatment of osteoarthritis and osteoporosis. A clinical study showed efficiency in reducing joint pain and improving patient mobilization when supplemented (ZIEGLER and SGARBIERI, 2009).

It is known that collagen is a protein of great importance for bones, tendons, cartilage, muscles, skin, hair and nails. There are several types of collagen, and type II is the main component of the joint cartilage matrix and can help prolong the independent lifestyle of an elderly person, improving their quality of life. The research aimed to evaluate the effect of a collagen mix composed of peptides, type II collagen and nutrients involved in the joint bone metabolism of active elderly. Volunteers with a minimum age of 60 years and physically active participated in the research. This is a non-randomized clinical trial conducted with the gymnastics group of the elderly of an Activity Center in Florianópolis – SC. Oral supplementation with the collagen mix composed of bioactive peptides of hydrolyzed collagen, intact type II collagen, silicon and nutrients involved in joint bone metabolism (Duo flex®) was administered for 90 days, and the next 30-day cycle of the supplement was always delivered before the end of the current cycle, so that the participants did not interrupt the treatment. These were also followed weekly via telephone contact to avoid withdrawal or interruption of treatment. Questionnaires were applied to evaluate symptoms related to sarcopenia, joint functionalities, characteristic skin, nails and hair health, and anthropometric measurements. The sample consisted of 50 elderly, most of them female (72%). Product consumption reduced pain, decreased stiffness and improved joint mobility according to the WOMAC questionnaire result. Duo flex® has significantly improved joint health and therefore can be an effective solution to delay joint manifestations. The results suggest that collagen mix can be used as a therapeutic approach for physically active elderly.

“…Other nutrients such as proteins and vitamin C act directly in the synthesis of collagen, an important component in the skin structure. They act directly on the specific functions acquired by the several combinations of structural amino acids and on the formation of hydroxylases which transform lysine and proline, nutrients which are responsible for the synthesis of this collagen 30,31,34,39,40 .…”

The most notable esthetic alterations observed during pregnancy occur to the skin, with an increase in thickness due to edema. It is believed that these problems are triggered and/or aggravated due to the small intake of some food items. The objective of this study was to evaluate the relationship of food consumption, water intake and the appearance of cutaneous and vascular alterations in pregnant women. Pregnant women participating in health programs in the municipality of Santos were enrolled, and answered questionnaires to verify healthy practices and attitudes, water intake and esthetic problems -cellulitis, striae, periorbital dark circles and varicose veins. To evaluate food consumption, a food frequency questionnaire (FFQ) adjusted for the study purpose was used. The sample was grouped in tertiles for food consumption and water intake related to each esthetic problem for performance of logistic regression models. 105 pregnant women at the mean age of 24.4 years participated in the study. The relationship between the consumption of food items which are source of protein, vitamin C and calcium were found as protective factors for striae (OR 0.62) in the tertile of highest consumption, as well as water intake for tertiles 2 (OR 0.62) and 3 (OR 0.61). As for varicose veins, cellulitis and periorbital dark circles this relationship was not statistically significant. It was observed that diets rich in protein, vitamin C, calcium and water intake (more than four glasses per day) was a protective factor against the appearance of striae in pregnant women.Keywords: Food Habits. Esthetics. Pregnancy. Skin. ResumoAs mais notavéis alterações estéticas durante a gestação ocorrem na pele com aumento da espessura em virtude do edema. Acredita-se que esses problemas podem ser engatilhados e/ou agravados devido à ingestão reduzida de certos alimentos.O objetivo do estudo foi avaliar a relação entre o consumo alimentar, ingestão hídrica e o aparecimento de alterações estéticas cutâneas e vasculares em gestantes. Participaram gestantes inseridas em programas de saúde municipal -Santos-SP, que responderam a questionários para verificar práticas e atitudes saudáveis, ingestão hídrica e problemas estéticos -celulite, estria, olheiras e varizes. Para avaliar o consumo alimentar foi utilizado questionário de frequência alimentar (QFA) ajustado para o propósito do estudo. A amostra foi agrupada em tercis de consumo alimentar e ingestão hídrica relacionados com cada problema estético para realização de modelos de regressão logística. Participaram 105 gestantes com média de idade de 24,4 anos. A relação do consumo de alimentos fonte de nutrientes funcionais com proteção aos problemas estéticos avaliados foram encontrados com valores significantes para estrias (OR 0,62) no tercil de maior consumo, assim como ingestão hídrica para os tercis 2 (OR 0,62) e 3 (OR 0,61) ajustadas por índice de massa corporal, idade, prática de atividade física e uso de protetor solar. Para varizes, celulite e olheiras essa relação apresentou valo...
