“…However, it should be taken into account that the mineral content may be influenced by growing conditions, such as soil and geographical factors (Ercisli and Ohran 2007). In addition, the bioavailability of minerals seems to be dependent on cultivar, the environment and harvest year (Bohn et al 2008). Some compounds such as ascorbic acid can help Fe absorption; on the other hand, iron uptake could be inhibited by strong chelators such phytic acid, some polyphenols and the divalent cations Ca, Zn, Co and Mg.…”

Fruits are rich in minerals, which are essential for a wide variety of metabolic and physiologic processes in the human body. The use of frozen fruits has greatly spread in the last years not only in the preparation of juices, but also as raw material for yogurts, candies, cookies, cakes, ice creams, and children's food. However, up to now there is no data about the mineral profile of frozen fruits. This is the first database to quantify the levels of minerals in 23 samples of frozen fruits, including the most used around the world and some native fruits from the Amazon rainforest in Brazil. Considering the Dietary Reference Intakes, 100g of frozen fruits can provide 0.2 to 2.8% of macro and 2.5 to 100% of microminerals for adults (31-50 years old). Although geographical differences should be considered, these data can help to plan diets and to develop population interventions aiming to prevent chronic diseases.

In individuals with chronic kidney disease, high dietary phosphorus (P) burden may worsen hyperparathyroidism and renal osteodystrophy, promote vascular calcification and cardiovascular events, and increase mortality. In addition to the absolute amount of dietary P, its type (organic versus inorganic), source (animal versus plant derived), and ratio to dietary protein may be important. Organic P in such plant foods as seeds and legumes is less bioavailable because of limited gastrointestinal absorption of phytate-based P. Inorganic P is more readily absorbed by intestine, and its presence in processed, preserved, or enhanced foods or soft drinks that contain additives may be underreported and not distinguished from the less readily absorbed organic P in nutrient databases. Hence, P burden from food additives is disproportionately high relative to its dietary content as compared with natural sources that are derived from organic (animal and vegetable) food proteins. Observational and metabolic studies indicate nutritional and longevity benefits of higher protein intake in dialysis patients. This presents challenges to providing appropriate nutrition because protein and P intakes are closely correlated. During dietary counseling of patients with chronic kidney disease, the absolute dietary P content as well as the P-to-protein ratio in foods should be addressed. Foods with the least amount of inorganic P, low P-to-protein ratios, and adequate protein content that are consistent with acceptable palatability and enjoyment to the individual patient should be recommended along with appropriate prescription of P binders. Provision of in-center and monitored meals during hemodialysis treatment sessions in the dialysis clinic may facilitate the achievement of these goals.

“…Phytate and its derivatives are also implicated in RNA export, DNA repair, signalling, endocytosis and cell vesicular trafficking (Lisbeth Bohn, et al;2008). Moreover, we also have noted that, phytic acid may have beneficial effects on human nutrition, reducing the risk of colon and breast cancer through action either as an anti-oxidant (Evers, et al, 1999;Graf.…”

“…Phytate mainly accumulates in protein storage vacuoles, and it locates in the aleurone layers of wheat, barley and rice or in the embryo of maize (Lisbeth Bohn, et al;2008). Selecting moderate phytate crop cultivars is considered as more important means than adding exogenetic phytase or sourdough (Leenhardt, Fanny, et al, 2005;Haros M, et al, 2001;Lopez HW, et al, 2003) into the food or the feed from wheat materials, or adjusting pH of dough (Leenhardt, Fanny, et al, 2005) to reduce phytate content.…”

A simple and effective method of determining the phytate content of a single wheat seed was considered necessary for selecting the materials of moderate phytate during early generations breeding. 23 wheat genotypes (16 winter wheat cultivars and 7 spring wheat cultivars) were firstly used as determining samples of phytate content (PC) and inorganic phosphorus content (IPC) of the whole meal, secondarily they were planted in two locations for two times (2004 and 2005). The all single plants were harvested by a plot from those sites, then 6 individual plants were randomly selected to save their seeds for each plot, and the seeds of other plants were grinded into whole meal to assay their PC and IPC. Subsequently, every seed from per individual plant was cut into two semi-grain seeds: the semi-grain seed without embryo (SGSWOE) and the semi-grain seed with embryo (SGSWE); the SGSWOE was carried out to assay colorimetric scoring values by inorganic phosphorus content (CSVIPC), while according to the CSVIPC index, the satisfied SGSWEs were saved to plant at next generation or the dissatisfied SGSWEs were eliminated. The results showed that there was significantly negative correlation between PC and IPC of the wheat meal from either the first samples or the materials harvested at those sites, and for the latter there was significantly negative correlation between PC and CSVIPC. There was no significant difference of CSVIPC among the SGSWEOs and SGSWE of the spikes and individual plants from the same plot or the same genotype at any sites. In conclusion the CSVIPC of the SGSWOEs can indirectly express PC level of the wheat meal: the higher the former was, the lower the latter was. So the CSVIPC of SGSWOE can be applied to assaying the level of corresponding SGSWE according to their index, and screening the individual plant of moderation phytate. Moreover, this method is characterized by high efficiency during breeding processing.
