“…Our findings revealed a linear fruit SSC decrease as the I dose increased. Similar results were observed by Consentino et al [ 31 ] who studied the combined effect between I biofortification and grafting in eggplant and found a reduced amount of fruit SSC in the biofortified plants. Concomitantly, SwE application enhanced the fruit SSC.…”

“…A comparable pattern of findings was described by Sabatino et al [ 19 ] who, by investigating the effect of I-enrichment on curly endive, found that yields decrease as the I dose increases. These findings could be related to the harmful effect of I on photosynthesis, as I is stored, largely, in chloroplasts [ 28 , 31 ]. Alongside mitigating the influence of higher doses of I, SwE supply may elicit plant yield due to the polysaccharide content that stimulates endogenous hormonal homeostasis [ 73 , 74 , 75 ].…”

“…There are several reports on the I biofortification of leafy and fruiting vegetables [ 19 , 28 , 29 , 30 , 31 ], as well as of field crops [ 32 , 33 ]. However, few studies have been conducted on the I biofortification of strawberries.…”

The horticultural sector is seeking innovative and sustainable agronomic practices which could lead to enhanced yield and product quality. Currently, plant biofortification is recognized as a valuable technique to improve microelement concentrations in plant tissues. Among trace elements, iodine (I) is an essential microelement for human nutrition. Concomitantly, the application of biostimulants may improve overall plant production and quality traits. With the above background in mind, an experiment was designed with the aim of assessing the interactive impact of a seaweed extract-based biostimulant (SwE) (0 mL L−1 (served as control) or 3 mL L−1 (optimal dosage)) and 0, 100, 300, or 600 mg L−1 I on the growth parameters, yield, fruit quality, minerals, and functional characteristics of the tunnel-grown “Savana” strawberry. SwE foliar application improved the plant growth-related traits, total and marketable yield, fruit color parameters, soluble solids content, nitrogen (N), potassium (K), and magnesium (Mg) fruit concentrations. Furthermore, an enhancement in the fruit dry matter content, ascorbic acid, and I concentration in fruits was detected when the SwE supply interacted with a mild I dose (100 or 300 mg L−1). The research underlined that combining SwE application and I biofortification increased the strawberry yield and quality and enhanced the plant nutritional status variation, thereby, determining a boosted strawberry I tolerance.

“…Recent studies in humans suggest that molybdenum could exert hypoglycemic effects [ 17 , 18 ]. However, although there are reports on leafy green vegetables biofortification with trace elements [ 19 , 20 , 21 , 22 ] including molybdenum [ 23 , 24 , 25 ], there are no studies about the consumption of biofortified food with molybdenum on glucose homeostasis in individuals and the mechanism of action has never been investigated. In this manuscript it was hypothesized that the consumption of biofortified food with molybdenum affects glucose homeostasis by influencing endogenous gut hormones in the healthy population.…”

Diabetes is expected to increase up to 700 million people worldwide with type 2 diabetes being the most frequent. The use of nutritional interventions is one of the most natural approaches for managing the disease. Minerals are of paramount importance in order to preserve and obtain good health and among them molybdenum is an essential component. There are no studies about the consumption of biofortified food with molybdenum on glucose homeostasis but recent studies in humans suggest that molybdenum could exert hypoglycemic effects. The present study aims to assess if consumption of lettuce biofortified with molybdenum influences glucose homeostasis and whether the effects would be due to changes in gastrointestinal hormone levels and specifically Peptide YY (PYY), Glucagon-Like Peptide 1 (GLP-1), Glucagon-Like Peptide 2 (GLP-2), and Gastric Inhibitory Polypeptide (GIP). A cohort of 24 people was supplemented with biofortified lettuce for 12 days. Blood and urine samples were obtained at baseline (T0) and after 12 days (T2) of supplementation. Blood was analyzed for glucose, insulin, insulin resistance, β-cell function, and insulin sensitivity, PYY, GLP-1, GLP-2 and GIP. Urine samples were tested for molybdenum concentration. The results showed that consumption of lettuce biofortified with molybdenum for 12 days did not affect beta cell function but significantly reduced fasting glucose, insulin, insulin resistance and increased insulin sensitivity in healthy people. Consumption of biofortified lettuce did not show any modification in urine concentration of molybdenum among the groups. These data suggest that consumption of lettuce biofortified with molybdenum improves glucose homeostasis and PYY and GIP are involved in the action mechanism.

“…Biofortification is considered a good strategy to deliver micronutrients to the populations and, among other agronomic practices [ 11 , 12 , 13 , 14 , 15 ], it represents a key technique to improve crop quality [ 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. It differs from fortification because there is no addition of nutrient supplements to the foods during food processing; rather, plants are grown under specific conditions to be naturally more nutritive.…”

Micronutrients are required in many reactions involved in physical activity and exercise. Most physically active people do not meet the body’s needs in terms of micronutrients through diet. The novelty of the present manuscript is the use of an innovative dietary approach to supply micronutrients to physically active people through biofortified food. Therefore, the key point of this study was to verify whether supplementation with biofortified vegetables—and specifically molybdenum (Mo)-enriched lettuce—in healthy volunteers affects essential regulators of body homeostasis and, specifically, hematological parameters, iron and lipid metabolism, and hepatic function. Twenty-four healthy volunteers were allocated in a double-blinded manner to either a control group that consumed lettuce, or the intervention group, which consumed Mo-enriched lettuce, for 12 days. Blood samples were collected at baseline (T0) and after 12 days (T1). We found that supplementation with Mo-enriched lettuce did not affect hematological parameters, liver function, or lipid metabolism, but significantly improved iron homeostasis by increasing non-binding hemoglobin iron by about 37% and transferrin saturation by about 42%, while proteins of iron metabolism (e.g., transferrin, ferritin, ceruloplasmin) were not affected. The serum molybdenum concentration increased by about 42%. In conclusion, this study shows that consumption of Mo-biofortified lettuce ameliorates iron homeostasis in healthy subjects, and suggests that it could be used as a new nutritional supplementation strategy to avoid iron deficiency in physically active people.
