Effect of intake of selected nutrients on skin firmness and elasticity in women.

Introduction: The proper functioning of the skin is influenced by a proper diet. The purpose of this study was to determine the effect of selected nutrients on selected skin parameters.

Methods: The study group included 59 women, who were divided into two age groups (under and over 40  years old).

Thyroid is an endocrine gland that is responsible for producing and releasing two hormones: triiodothyronine (T3) and thyroxine (T4). Hypothyroidism as the disorder happens when the synthesis of those hormones is impaired. It is most commonly caused by the chronic autoimmune inflammation of the thyroid, referred to as Hashimoto’s disease.

Zinc, Copper, and Iron in Selected Skin Diseases.

Trace elements are essential for maintaining the body's homeostasis, and their special role has been demonstrated in skin physiology. Among the most important trace elements are zinc, copper, and iron. A deficiency or excess of trace elements can be associated with an increased risk of skin diseases, so increasing their supplementation or limiting intake can be helpful in dermatological treatment.

In Vitro Assessment of the Bioaccessibility of Zn, Ca, Mg, and Se from Various Types of Nuts.

The bioaccessibility of zinc (Zn), calcium (Ca), magnesium (Mg), and selenium (Se) from various nuts (Brazil nuts, walnuts, peanuts, almonds, cashews, pecans, hazelnuts, macadamia nuts, and pistachios) was assessed using a simulated two-phase model of enzymatic digestion in vitro. The levels of Zn, Mg, and Ca were determined by atomic absorption spectrometry, and Se was measured by inductively coupled plasma-mass spectrometry. All tested nuts were good sources of Mg, and most, except macadamia nuts, were also good sources of Zn (the standard portion covers over 15% of NRV-R (UE) 1924/2006).

Antioxidant Properties of Maqui Berry Extract ( (Mol.) Stuntz) and Its Potential Photoprotective Role on Human Skin Fibroblasts.

Maqui berry () is characterized by antioxidant and anti-inflammatory properties. The aim of this study was to evaluate the effect of maqui berry extracts on human skin fibroblasts (NHSFs) exposed to ultraviolet radiation (UVB). The photoprotective properties of the extracts were investigated via the determination of the total polyphenolic content (TPC) and antioxidant capacity (DPPH), and the chemical composition was assessed.
