Special Issue Information

Dear Colleagues,

Traditional medicine and its different uses are an important part of human cultures and for centuries were the only way to promote health, fulfilling the fundamental role of curing diseases in humans. Thus, plants with various healing effects have been used in most cultures around the world, consumed either topically or through ingestion. Bioactive compounds from plants can be extracted through different methods, conditions and plant material treatments to increase their concentrations or purity. Their anti-inflammatory, antioxidant, anticarcinogenic, etc., biological functions are just some of the beneficial effects demonstrated by compounds obtained from natural sources. Bioaccessibility can be defined as the fraction of a food matrix that, as consequence of release through digestion, is susceptible to crossing the intestinal barrier or moving to the colonic phase. There are factors that greatly affect the bioaccessibility of compounds, such as the oxidation of some nutrients or the chemical changes that they undergo during preparation.

We invite contributions discussing extraction and optimization techniques, chemical properties, the characterization and identification of bioactive compounds, biological activities, health benefits and the bioaccessibility of functional foods and nutraceuticals.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Foods is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs).

Prosthechea karwinskii is an endemic orchid of Mexico with cultural significance for its ornamental, food, religious, and medicinal uses. In traditional medicine, diabetic patients use the leaves of this plant to lower glucose levels. The present study evaluated the effect of P. karwinskii leaves extract on the antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT) in a model of obese rats with insulin resistance for its nutraceutical potential to reduce insulin resistance and oxidative stress. Obesity and insulin resistance were induced with 40% sucrose in water for 20 weeks. Four groups (control rats, obese rats, obese rats administered the extract, and obese rats administered metformin) were evaluated. Extract compounds were identified by UHPLC-ESI-qTOF-MS/MS. Glucose, insulin, triglyceride, and insulin resistance indices (HOMA-IR and TyG), as well as the activity of the antioxidant enzymes, increased in rats in the obese group. Administration of P. karwinskii extract and metformin reduced glucose, insulin, triglyceride, and insulin resistance indices and antioxidant enzyme activity to values similar to those of the control group. Therefore, this study shows the nutraceutical potential of P. karwinskii extract as an ingredient in the formulation of dietary supplements or functional foods to help treat diseases whose pathophysiology is related to oxidative stress and insulin resistance.
