Article Synopsis
  • Buriti pulp oil contains beneficial bioactive substances and lipids that may help protect against cardiovascular and inflammatory diseases.
  • In a study with 108 Swiss mice over 90 days, various combinations of buriti oil and olive oil were tested, showing stability and effective metabolic interactions without affecting food intake or weight gain.
  • The strongest cardioprotective effect was seen in the group combining buriti oil and extra virgin olive oil, suggesting that this combination could be a valuable dietary supplement for people.

Different fatty acid proportions produce potential inflammatory and metabolic changes in organisms. However, the evidence for how each fatty acid mediates the metabolic pathway, and its lipid stability remains controversial. To resolve this controversy, the present study investigated the metabolic effects of cold-pressed linseed (LG), coconut (CG), and baru (BG) oils in comparison to those of soybean oil (SG) in mice, in terms of their oil characterization and stability.

Article Synopsis
  • Information on medicinal plants for diabetes treatment is limited, prompting a study to analyze the levels of macroelements and microelements in three plant species and their teas.
  • The analyses revealed high concentrations of potassium (K) and phosphorus (P) in dry samples, with several other elements present above WHO's permissible levels.
  • Despite the risk assessments showing plant teas to be safe for consumption (HQ < 1), caution is advised for diabetics using these plants, especially in capsule or concentrated forms, due to potential health risks.

The macauba palm (Acrocomia aculeata) is native of tropical America and is found mostly in the Cerrados and Pantanal biomes. The fruits provide an oily pulp, rich in long chain fatty acids, and a kernel that encompass more than 50% of lipids rich in medium chain fatty acids (MCFA). Based on biochemical and nutritional evidences MCFA is readily catabolized and can reduce body fat accumulation.

Background: Sesame and flaxseed oils, which are rich in essential n-6 and n-3 polyunsaturated fatty acids, are widely consumed. We have determined the optical behavior with respect to the quality and identity of cold-pressed sesame and flaxseed oils. The effects of these oils and their combinations on metabolic parameters in animal models were also measured.

Background: The Brazilian leguminous tree locally known in the Cerrado Biome as baru (Dipteryx alata Vog), provides a healthy edible oil source. The proteinaceous cake remaining after oil extraction could be transformed into new products to foodstuff development, such as protein concentrates and isolates, adding value to the production chain. In this study, it is described the preparation and characterization of baru nut protein isolate (BPI) from deffated baru flour, and measurements of its functional, nutritional, and thermal properties, in comparison to the more common vegetable (soybeans) and animal (casein and albumin) protein sources of the food industry.
