Despite strong correlations linking whole-grain consumption to reductions in heart disease, the physiological mechanisms involved remain ambiguous. We assessed whether Salba (Salvia Hispanica L.) whole grain reduces postprandial glycemia in healthy subjects, as a possible explanation for its cardioprotective effects observed in individuals with diabetes. The study used acute, randomized, double-blind, controlled design in which 11 healthy individuals (6 males and 5 females; body mass index 22.3+/-2.8 kg/m(2)) received 0, 7, 15 or 24 g of Salba baked into white bread. Capillary samples and appetite ratings were collected over 2 h after consumption. A dose-response reduction in postprandial glycemia (P=0.002, r(2)=0.203) was observed with all three doses of Salba, significantly decreasing incremental areas under the curve (iAUCs) and time point-specific blood glucose (P<0.05). Appetite ratings were decreased at 60 min after high, 90 min after high and intermediate and at 120 min after all treatments (P<0.05). Decrease in postprandial glycemia provides a potential explanation for improvements in blood pressure, coagulation and inflammatory markers previously observed after 12-week Salba supplementation in type II diabetes.
The purposes of the present study were to analyze liver inflammation and endothelial dysfunction in an experimental model of metabolic syndrome (MS) induced by chronic administration of a sucrose-rich diet (SRD) and to evaluate the effects of chia seed as a therapeutic strategy. Male Wistar rats were fed with a reference diet (RD) for 6 months or a SRD for 3 months. Then, the latter group was randomly divided into two subgroups. One subgroup continued receiving the SRD for up to 6 months and the other was fed with a SRD where whole chia seed was incorporated as a source of dietary fat for the next 3 months (SRD + CHIA). Results showed that rats fed a SRD for a long period of time developed dyslipidemia, hyperglycemia, inflammation and endothelial dysfunction. Hepatic NAS, IL-1β, NFκB p65, PAI-1, and F4-80 expression, as well as MPO activity were significantly increased and IL-10 expression was significantly decreased; this was accompanied by increased plasma IL-6 and TNF-α levels in rats fed a SRD. In addition, serum and liver nitric oxide (NO) levels and nitric oxide synthase (NOS) were significantly increased in the SRD group. In addition, a significant increase in hepatic iNOS expression and a positive correlation of this with liver NFκB p65 was found. We observed a significant increase in hepatic intercellular adhesion molecule (ICAM), and a negative correlation of this with liver Nrf2 was found. The administration of chia seed for 3 months reversed dyslipidemia, hyperglycemia, inflammation and endothelial dysfunction. In the liver tissue, NAS, IL-1β, IL-10, NFκB p65, PAI-1, and F4-80 expression and MPO activity were normalized. Serum and liver NO and NOS levels and hepatic iNOS expression were decreased and this last one was associated with a decrease in liver NFκB p65 levels. Hepatic ICAM-1 was normalized and negatively correlated with liver NrF2 levels. This study showed new aspects of liver inflammation and endothelial dysfunction in dyslipidemic insulin resistant rats chronically fed with a sucrose-rich diet. In addition, we demonstrated new properties and molecular mechanisms associated with beneficial effects on inflammation and endothelial dysfunction of chia seed as a therapeutic strategy.

Mechanistic basis
This use is associated with the plant's anti-inflammatory action. Further evidence for that pharmacology:
The aim of this review was to compile evidence and understand chia seed effects on unbalanced diet animal studies and the molecular mechanisms on metabolic biomarker modulation. A systematic review was conducted in electronic databases, following PRISMA recommendations. Risk of bias and quality was assessed using SYRCLE toll and ARRIVE guidelines. Seventeen articles were included. Throughout the studies, chia's main effects are associated with AMPK modulation: improvement of glucose and insulin tolerance, lipogenesis, antioxidant activity, and inflammation. Details about randomization and allocation concealment were insufficient, as well as information about blind protocols. Sample size, chia dose, and number of animals evaluated for each parameter were found to be lacking information among the studies. Based on experimental study data, chia has bioactive potential, and its daily consumption may reduce the risk of chronic disease development, mainly due to the antioxidant, anti-inflammatory, hypoglycemic, and hypolipidemic effects of the seed. PRACTICAL APPLICATION: The consumption of chia seeds may improve lipid profile, insulin and glucose tolerance, and reduce risk of cardiovascular disease. Whole seed or its oil presents positive effect, but the effects of chia oil can act faster than the seed.
The consumption of chia seed (Salvia hispanica L.) has increased in recent years due its high content of omega-3 fatty acids and dietary fiber. This seed also has a high concentration of proteins and essential amino acids, becoming a promising source of bioactive peptides. The objective of this review was to identify the composition and the beneficial effects of chia seeds (S. hispanica L.), their proteins, peptides, and their potential impact on human health. The UniProt database was used to identify the chia proteins and their amino acid sequences. The BIOPEP database was used to analyze the peptides's bioactive potential. A total of 20 proteins were cataloged in chia seed, 12 of those were involved in the regular metabolic processes of the plant cells. However, eight proteins were specifically related to production and storage of plant lipids, thus explaining the high concentration of lipids in chia seeds (around 30%), especially omega-3 fatty acids (around 20%). The analyses of amino acid sequences showed peptides with bioactive potential, including dipeptidyl peptidase-IV inhibitors, angiotensin-converting enzyme inhibitors, and antioxidant capacity. These results correlated with the main health benefits of whole chia seed in humans such as antioxidant capacity, and hypotensive, hypoglycemic, and anticholesterolemic effects. Such relation can be associated with chia protein and peptide compositions and therefore needs further investigation in vitro and in vivo.
