Tomato and its derived products have a very interesting nutritional value in addition to prominent antioxidant, anti-inflammatory, and anticancer activities. Tomatoes are generally quite safe to eat. ⋯ On the other hand, the synthesis and accumulation of these bioactive molecules depends on many other factors, such as environmental conditions. In this sense, this review briefly highlights the relationship between the chemistry of tomato and its derived products and their beneficial or harmful effects on human health, such as gastroesophageal reflux disease or heartburn, allergies, kidney and cardiovascular disorders, prostate cancer, irritable bowel syndrome, lycopenodermia, body aches, arthritis, and urinary problems.

The interest in non-invasive methods of body composition assessment is on the rise in health care, especially because of its association with clinical outcomes. Technology has revolutionized our understanding of body composition abnormalities, clinical prognostication, and disease follow-up, but translation to bedside is limited, especially in terms of cost effectiveness. Computed tomography gained increased attention in cancer and sarcopenia studies, for instance. ⋯ Compelling evidence indicates these methods can be used to accurately and precisely measure skeletal muscle mass, adipose tissue, and edema; diagnose malnutrition-related diseases; and aid in determining prognoses. To apply this technology properly, it is important to understand the advantages and disadvantages of each technique in specific situations of interest. This review introduces concepts and reference studies published in the scientific literature about these techniques and describes important limitations and considerations necessary to incorporate these methods into clinical practice.

Little is known about the indicators to assess malnutrition in patients with idiopathic pulmonary fibrosis (IPF). This study aimed to determine the following: 1) the prevalence of malnutrition in IPF patients; 2) the nutritional indicators predictive of low fat-free mass (FFM) as measured by bioimpedance analysis; 3) the IPF patients' characteristics associated with low FFM. ⋯ Malnutrition occurred in nearly one-third of IPF patients. Malnutrition screening should become systematic based on BMI and MAC, which are good clinical indicators of low FFMI. We propose a practical approach to screen malnutrition in IPF patients.

This study aimed to examine the cross-sectional association between dietary and serum selenium measures and depressive symptoms among a nationally representative sample of US adults. ⋯ Our study supports an inverse association between participants recommended dietary intake of selenium and depressive symptoms. Although results were not statistically significant for the association by quartile of serum selenium concentrations and depressive symptoms, a U-shaped association was identified.
