RESUMEN

The market has seen a rapid increase in animal-free products intended to replace animal-based foods due to concerns for human health and environmental sustainability. However, there is a lack of consistent terminology for these products, with various terms being used interchangeably, creating ambiguity. To address this issue, we propose a systematic nomenclature that defines the most commonly used terms, namely alternative, substitute, replacement, and analog, along with examples of each. In this nomenclature, a substitute primarily serves a culinary purpose, while a replacement is concerned with nutritional properties. An analog strives to satisfy both culinary and nutritional attributes to closely mimic animal-based foods in terms of sensory, nutritional, and functional characteristics. The term "alternative" serves as an umbrella term encompassing all possibilities. This work aims to promote a clearer understanding of such products and their intended use and facilitate a unified use of terminology across disciplines. This will also enable informed decision-making for consumers and greater transparency in the food industry. The health and environmental implications of these products are not discussed in this perspective.

RESUMEN

Dried plums contain bioactive components that have demonstrated antioxidant and anti-inflammatory effects. The objective of this study was to determine if dried plum consumption reduces the risk factors for cardiovascular disease (CVD) in postmenopausal women, specifically examining lipid profiles, oxidative stress, antioxidant capacity, and inflammation in a dose-dependent manner. We conducted a 6-month, parallel-design controlled clinical trial, where 48 postmenopausal women were randomly assigned to consume 0, 50, or 100 g of dried plum each day. After 6 months of intervention, total cholesterol (TC) in the 100 g/day treatment group (P = .002) and high-density lipoprotein cholesterol in the 50 g/day treatment group (P = .005) improved significantly compared to baseline. Inflammatory biomarkers interleukin-6 (P = .044) and tumor necrosis factor-α (P = .040) were significantly lower after 6 months within the 50 g/day dried plum group compared to baseline. Moreover, total antioxidant capacity increased significantly within the 50 g/day group (P = .046), and superoxide dismutase activity increased significantly within both 50 and 100 g/day groups (P = .044 and P = .027, respectively) after 6 months compared to baseline. In addition, plasma activities of alanine transaminase (P = .046), lactate dehydrogenase (P = .039), and creatine kinase (P = .030) were significantly lower after 6 months in the 50 g/day dried plum group. These findings suggest that daily consumption of 50-100 g dried plum improves CVD risk factors in postmenopausal women as exhibited by lower TC, oxidative stress, and inflammatory markers with no clear dose dependence.

RESUMEN

Emerging research indicates that nuts are a source of health-promoting compounds demonstrating cardioprotective benefits. However, most studies have assessed the effect of single nuts rather than a nut mixture. The objective of this study was, therefore, to examine the effect of mixed-nut consumption on cardiovascular disease (CVD) risk factors in overweight and obese adults. In a randomized, parallel-arm, controlled trial, 48 participants consumed isocaloric (250 kcal) amounts of pretzels or mixed-nuts. Body weight (BW) (p = 0.024), BMI (p = 0.043), and insulin levels (p = 0.032) were significantly lower in the nut group compared to the pretzel group. Mixed-nut consumption also significantly reduced glucose (p = 0.04) and insulin (p = 0.032) levels after 4 and 8 weeks compared to baseline, respectively. Lactate dehydrogenase of the nut group was significantly lower than the pretzel group (p = 0.002). No significant differences were detected between groups for triglycerides, LDL-C, and HDL-C. However, pretzel consumption increased triglycerides (p = 0.048) from 4 weeks to 8 weeks. Moreover, LDL-C increased (p = 0.038) while HDL-C transiently decreased (p = 0.044) from baseline to 4 weeks. No significant lipid changes were detected within the nut group. Our results suggest that supplementing the diet with mixed-nuts could improve CVD risk factors by improving BW and glucose regulation in comparison to a common carbohydrate-rich snack without promoting the negative effects on lipids detected with pretzels.

RESUMEN

BACKGROUND: A large number of illnesses, afflicting one-third of the world's population, have been attributed to zinc deficiency. Inadequate dietary intake of bioavailable forms of zinc is considered the most frequent cause of zinc deficiency, which is most common in arid regions of developing countries. OBJECTIVE: To employ a modeling approach in a test population to analyze how best to eliminate zinc deficiency using different plausible dietary scenarios. METHODS: A comprehensive database was built upon food consumption patterns of two population groups residing in a village and a suburb in semiarid central Iran near Isfahan city. A database was created on zinc and phytic acid concentrations of different foods and ingredients consumed by the study populations. A zinc intake model was constructed and parameterized accounting for bioavailability and model input uncertainties. RESULTS: The zinc intake of about one-third of both study populations, which did not differ significantly in their rates of zinc deficiency, was below the Estimated Average Requirement (EAR) for zinc. Scenario analyses predicted that at the current rate of food consumption, it would take up to 60 years for 97.5% of the population to meet their zinc EARs. Fortification of wheat flour and biofortification of wheat grains would result in 93% and 88% of the population, respectively, achieving their EARs in 15 years. CONCLUSIONS: The modeled results suggest that fortification and biofortification are the most effective and sustainable strategies to combat zinc deficiency. The methodology developed in this study is general and is shown to be a useful tool for the analysis of possible future trends and intervention scenarios.

RESUMEN

It is well-known that deficiency or over exposure to various elements has noticeable effects on human health. The effect of an element is determined by several characteristics, including absorption, metabolism, and degree of interaction with physiological processes. Iron is an essential element for almost all living organisms as it participates in a wide variety of metabolic processes, including oxygen transport, deoxyribonucleic acid (DNA) synthesis, and electron transport. However, as iron can form free radicals, its concentration in body tissues must be tightly regulated because in excessive amounts, it can lead to tissue damage. Disorders of iron metabolism are among the most common diseases of humans and encompass a broad spectrum of diseases with diverse clinical manifestations, ranging from anemia to iron overload, and possibly to neurodegenerative diseases. In this review, we discuss the latest progress in studies of iron metabolism and bioavailability, and our current understanding of human iron requirement and consequences and causes of iron deficiency. Finally, we discuss strategies for prevention of iron deficiency.

RESUMEN

The aim of this study was to estimate the zinc (Zn) and iron (Fe) status of different age groups in rural (Rooran) and suburban (Khomeini Shahr) populations in central Iran, to relate the Zn status to Zn intake from animal and plant foods, and to examine the relationship between Zn and Fe status. Blood samples from 341 subjects including preschool children (27), schoolchildren (157), women (91), and men (66) were analyzed for serum zinc (SZn), serum ferritin (SF), total C-reactive protein, and hemoglobin. Daily Zn and phytic acid (PA) intakes from major food groups were estimated using a 3-day weighed food record. The overall prevalence of Zn deficiency based on low SZn was 5.9 % in Rooran and 7.2 % in Khomeini Shahr. Anemia was higher in the village than in the suburb (33.5 % vs. 22.7 %; p = 0.04) and almost half of the anemia in Khomeini Shahr and 36 % in Rooran was associated with iron deficiency (ID) based on low SF. The PA:Zn molar ratio in the diet was 10 - 13, indicating a diet of moderate Zn bioavailability. About 18 % of the population consumed less Zn than their WHO Estimated Average Requirements. There was no association between Zn status and Fe status. The modest prevalence of Zn deficiency in the study populations can be explained by a relatively high Zn intake from animal source foods. Anemia however is a serious public health problem affecting some 30 % of the subjects, with almost half due to ID. The lower Fe status than Zn status could be due to the frequent consumption of tea and dairy products.
