ABSTRACT

The influence of diet inclusion of vitamin and mineral complex (VMC), potassium and magnesium in the form of asparaginate on micronutrient status, body composition and biochemical parameters in patients with diabetes mellitus type 2 (DM2) has been investigated. 120 female patients with DM2 and obesity of I-III degree (mean age - 58 +/- 6 years) have been included in the study. The patients were divided into two groups: main group (n = 60) and control group (n = 60). For 3 weeks patients of both groups received a low-calorie diet (1600 kcal/day). Patients of the main group received VMC, providing an additional intake of vitamins C and E (100-120% RDA), beta-carotene (40% RDA), nicotinamide (38% RDA), pantothenic acid and biotin (60% RDA), vitamins B12, B2 and folic acid (75-83% RDA), vitamins B1 and B6 (160-300% RDA), zinc (100% RDA) and chromium (400% RDA), and also received magnesium (17.7% RDA) and potassium (9.4% RDA) in the form of asparaginate. Body composition, biochemical parameters and micronutrient status (blood serum level of vitamins C, D, B6, B12, folate, potassium, calcium, magnesium, zinc, phosphorus) were evaluated in all patients before and after the 3-week course of diet therapy. After the low-calorie diet therapy average body weight reduction was 4.2 +/- 0.2 kg in the main group, and 4.4 +/- 0.1 kg in the control group, without statistically significant differences between groups. Statistically significant decrease of total cholesterol, triglycerides, and glucose concentration in blood serum was registered in both groups. It should be noted that in the control group glycemia decreased on 1.2 +/- 0.1 mmol/l, while the main group showed a decrease on 1.8 +/- 0.1 (p < 0.05) to normal values (5.4 +/- 0.1 mmol/l). Initial assessment of vitamin and mineral status revealed that most patients were optimal supplied with vitamins and minerals. After the dietotherapy significant increase of vitamin C, 25-hydroxyvitamin D, vitamin B6, folate, vitamin B12, potassium, magnesium, calcium, zinc and phosphorus concentration in blood serum was observed in patients receiving VMC. While in the control group statistically significant decrease of vitamin C, magnesium, zinc and phosphorus concentration in blood serum after the treatment was revealed. The obtained data shows the necessity of addition of the vitamin-mineral complex to the diet of patients with DM2 and obesity.

ABSTRACT

A 5-fold decrease of the content of vitamin mixture in the ration and exclusion of vitamin E from this mixture over 4 weeks led to a significant growth delay in rats initially weighing 58.1±0.5 g, but was inessential for the growth rates of animals weighing 107.1±1.1 g. The decrease in the levels of vitamins A and B2 in the liver and of 25-hydroxyvitamin D in the plasma of younger rats was more significant, this indicating their higher sensitivity to alimentary vitamin deficit. The increase in vitamin content in the ration to 100% over 5 days led to a significant body weight increment but did not restore vitamin levels in the liver, restoring, however, plasma levels of vitamins E and 25-hydroxyvitamin D. Addition of 50% vitamin content of the vitamin mixture for controls to vitamin-deficient rations of older rats for 2 weeks improved the levels of vitamins B1 and B2, but was virtually inessential for the liver content of vitamins A and E. High dose (158-200%) vitamins in animals of both age groups repaired the deficit of all vitamins, except vitamin A, despite the fact that its doses were the highest. These results validate long-term vitamin consumption for repair of their deficit.

ABSTRACT

Effect of wheat bran on the vitamin status of rats adequately provided with vitamins or insufficiently supplied with vitamins has been investigated. 32 male Wistar weaning rats (initial body mass--49-67g) were randomly divided into 4 groups and fed with complete semi-synthetic diet, containing 100 or 20% of vitamin mixture with or without addition of wheat bran (5% of diet mass) for 35 days. The animals of the control group received 100% of vitamin mixture without adding of wheat bran; 2 group--received those diet with wheat bran; 3 deficient group--20% of vitamin mixture with full exclusion of vitamins E, B1 and B2; 4 group--20% of vitamin mixture and wheat bran. The inclusion of wheat bran in full semi-synthetic diet has been accompanied by significant decrease of alpha-tocopherol liver content on 17% (p = 0.006), significant increase of vitamin B1 liver level on the 16% (p = 0.027) and blood plasma vitamin D elevation on 19% (p = 0.017), as well as a tendency (p = 0.059) to increase the liver level of vitamin B2. Indicators of vitamin A status as well as plasma vitamin E concentration, liver and blood plasma MDA levels were not changed in this group rats. The 5-fold reduction of the vitamin mixture quota and the exclusion of vitamins E, B1 and B2 resulted in a significant (p < 0.05) 1.6-1.8 fold decreased in animal body weight and liver mass and the manifestation of the deep external signs of vitamin deficiency. Young animals were more sensitive than adult animals to a lack of vitamins in the diet. Vitamin A (retinol palmitate) liver content in rats from this group was 25.1-fold reduced, vitamin E (alpha-tocopherol)--2.1-fold, vitamins B1 and B2--by 57 and 38% compared with animals received a complete control diet (p < 0.05). Blood plasma concentration of vitamins A, E, D was 19-34% decreased. Adding of bran in vitamin deficit diet led to increased consumption of vitamin B--on 40%, vitamins B2 and E--21%, both due to their natural content in the bran, and as a result of increased eatability of the feed by 16% relative to deficient group due to improved taste of the diet. Enrichment of vitamin scarce diet with wheat bran led to an increase in body weight by 56%, the efficiency of the diet by 67%. This circumstance didn't allow to reveal the effect of dietary fiber on the vitamin status of rats with polyhypovitaminosis. The significant (p < 0.05) increase of retinol plasma level by 34% and liver and blood plasma tocopherol content by 17% and 22% and reduction of MDA blood plasma level by 24% took place in animals from this group compared to a group of rats receiving vitamin deficit diet without any effect on liver MDA level, liver vitamin A, B1 and B2 content and heart coenzyme Q10 level. The results obtained suggest that wheat bran inclusion in the diet of rats adequately supplied with vitamins may lead to a deficiency of vitamin E.

ABSTRACT

The effect of 5% dietary wheat bran (WB) on the correction of combined vitamin deficiency by two doses of vitamins (physiological and enhanced) has been analyzed using a rat model (8 groups, n = 8/group). Vitamin deficiency in male weanling Wistar rats (58.1 ± 0.5 g) was induced by 5-fold reduction of vitamin mixture amount in the feed and complete vitamin E, B1 and B2 exclusion from the mixture for 30 days, then deficit was corrected within 5 days. Rats from control group were fed a complete semisynthetic diet containing microcrystalline cellulose 2%. Vitamin deficient diet for 35 days resulted in reduced (p < 0.05) levels of vitamin A in the liver by 25 fold, vitamin E and B1--2.0-2.3 fold, vitamin B2--by 40%, 25(OH)D blood plasma concentration--by 21% compared with the control. Feed consumption of the animals treated with vitamin deficient diet and WB was higher by 43% than in rats with vitamin deficit. Their rate of weight occupied the intermediate position between the rates of weight in deficit and in control animals, and they could not serve a full control to evaluate the WB impact on vitamin sufficiency. After filling the vitamin diet content to an adequate level vitamin E liver content was fully restored. To restore vitamins B1 and B2 liver level higher doses of vitamins (120-160% of adequate content) were required, and to restore the reduced levels of vitamin A in rat liver even 2-fold increased dose of vitamin A was insufficient. The diet enrichment with WB had no effect on vitamin B1 and B2 liver content, regardless of the amount of vitamins in the diet. Adding fiber to the diet of animals adequately provided with vitamins resulted in significantly 1,3-fold increase of 25(OH)D blood plasma concentration and a slight but significant decrease of α-tocopherol liver level by 16% as compared to rats not receiving WB. The enrichment of rat diet with dietary fibers worsened restoration of the reduced vitamin E status not only by filling vitamin content in the diet to an adequate level, but also by using 2-fold enhanced dose of vitamin. Within 5 days deficiency of vitamins A, B1, B2 was not eliminated with increasing vitamin diet content to an adequate level. Higher doses of vitamins are needed for the complete correction of vitamin status. The addition of vitamins to an adequate level was sufficient to normalize the elevated liver levels of MDA in rats with combined vitamin deficiency that may be associated with vitamin E status improvement. The diet enrichment with fiber did not affect on the intensity of lipid peroxidation in rat liver regardless of their provision with vitamins.

ABSTRACT

The efficiency of the correction of combined alimentary vitamin deficit in male Wistar rats (body weight 90-121 g) fed standard diet or enriched with omega-3 polyunsaturated fatty acids diet (by replacing sunflower oil (4.5% of the diet) with linseed oil) with different doses (physiological and enhanced) of vitamins has been investigated. The control group of animals (n = 12) received a complete semisynthetic diet during all experimental period (42 d). The animals of the test groups (each of 20 rats) received vitamin-deficient diet containing sunflower or linseed oil and 20% per cent of vitamin mixture amount in control diet from which vitamin E had been excluded. After 28 days of such feeding each of test groups was divided into two subgroups (6-8 rats in each), and the next 14 days the animals of subgroups received the diet with different degree of vitamin compensation (50 or 180% percent of vitamin content in the diet of the control group). The addition of both low and high vitamin dose in deficient diet based on standard fat component did not compensate the reduced liver vitamin A content, which amounted to 47.4% of the level in the liver of the control group. The lack of vitamin E in animals was eliminated only after adding of the enhanced dose of vitamin E to the ration. Recovering of decreased plasma and liver B2 level, plasma 25(OH)D and liver vitamin B1 content have been occurred after addition of the low dose of these vitamins to rat diet. Increasing of omega-3 PUFA diet level improved vitamins A and D sufficiency to some extent, but was accompanied by the significant reduction of rat liver alfa-tocopherol content both under combined vitamin deficiency (by 14%) and increased vitamins consumption (by 43%). PUFA enrichment of the diet of rats with vitamin deficiency had no impact on vitamin B1 and B2 liver level. The use of high doses of vitamins for a long time to eliminate a combined deficiency of vitamins has been proved.

ABSTRACT

Using the model of combined vitamin deficiency based on 5-fold reduction of the amount of vitamin mixture in semi-synthetic diet and on vitamin E exclusion from the mixture, the influence of omega-3 polyunsaturated fatty acids (PUFA) on vitamin and antioxidant status has been investigated. The enrichment of rat diet with PUFA was achieved by replacing of sunflower oil (4.5% of the diet) on linseed oil. This substitute led to omega-3 PUFA elevation from 0.03 to 2.4 g per 100 g of food and PUFA and saturated fatty acids diet ratio increased from 1.3 to 1.9. The diet treatment with PUFA did not affect blood plasma retinol concentration and total vitamin A (retinol palmitate and retinol) rat liver content, while liver retinol significantly 1,5-fold elevated. Despite of preliminary equation of tocopherols content in vegetable oils (up to 60 IU per 100 g by adding dl-alpha-tocopherol to linseed oil) the consuming of linen oil deteriorated animal vitamin E supply. The liver alpha-tocopherol content significantly decreased by 14%, its blood plasma concentration insignificantly decreased by 26%, while the amount of beta - and gamma-tocopherol significantly increased in 5,4-fold. At the same deprivation of vitamin D in the diet of rats treated with linseed oil 25(OH)D blood plasma concentration was 1,3-fold higher compared with the animals treated with sunflower oil, but the difference did not reach significance reliable. In this case, this index had significant differences from that of the receiving adequate diet rats in control group, having 2-fold higher concentration of vitamin D transport form in blood plasma. PUFA enrichment of the combined vitamin-deficit diet did not affect liver level of vitamin C, vitamin B1 and vitamin B2. Contrary to the assumptions, the enrichment with PUFA of vitamin-deficient diet did not lead to a further increase of liver MDA level and a decrease of liver ascorbic acid content, which is typical for animals in combined vitamin deficiency. The deterioration of vitamin E status at enriched with PUFA vitamin-deficient diet requires the additional intake of this vitamin for maintaining of vitamin E sufficiency.

ABSTRACT

The recommended daily intakes of vitamins in different countries have been compared. The data on consumption of vitamins and vitamin status are submitted. It is noted that since 2008 the values of recommended daily intakes of vitamin-antioxidants C and E and folate in Russia as in other countries has been significantly increased. The recommended vitamin D consumption in Russia has been increased 2-3-fold as in most European countries and USA, while vitamin A recommended intake, on the contrary, has been reduced by 10%. Monitoring of vitamin status of various groups of adult population (by vitamin serum blood level evaluation) during the period since 2003 to 2011 has shown that that since 2003 deficiency of B group vitamins takes place in 10-47% of surveyed, vitamin D insufficiency was detected in 20.7% of adults. Thus the deficiency of these micronutrients has been determined much more often than the deficit of vitamins E and C (2.8-11%). The key causes of vitamin deficiency among the population in current conditions have been discussed. The main ways of increasing of diet vitamin value by means of fortified foods usage or/and vitamin and mineral complexes intake have been considered. The effective and safe levels of food enrichment have been examined. Harmonized with the EU documents and Codex Alimentarius acting sanitary rules and regulations which govern the enrichment of food products of mass consumption with vitamins and minerals have been commented upon. The history of food enrichment (fortification) with vitamins and salt iodization in our country and abroad has been described. Basing on the experience of several countries in which the mandatory enrichment of regularly consumed food products (flour, breakfast cereals) had compensated inadequate intake of vitamin D, group B, iodine and iron to a large extent, the conclusion on the feasibility and health benefits of fortified foods intake has been done.

ABSTRACT

Addition of a vitamin-mineral complex (VMC) to a standard hypocaloric diet leads to a positive dynamics of antropometric characteristics in patients with obesity 1st and 2nd degrees which is comparable to effectiveness of standard dietotherapy (dietary treatment) traditionally used in complex treatment of obesity. Addition of 1,8 mg of vitamin B2 as part of VMC to a hypocaloric diet is shown to be inadequate in eradication of marginal provision of riboflavin when using diets reduced in calories.

ABSTRACT

The article concisely illustrates the vitamin and mineral state of population of town of Slavutich, including personal of Chernobyl Nuclear Power Station, children of pre-school age and pregnancy women, studied in 1992. Vitamins and minerals deficiency in the main of C and B vitamins and selenium was revealed in all the studied groups. Appropriate measures were developed and introduced to eliminate the detected dusturbances; but however some unsolved problems remained. Taking into account the forthcoming 20th anniversary of Chernobyl disarter, the authors of the come back to considering the obtained data in hope to atlract attention of medical scientific and public to the remained unsolved problems of micronutrient deficiency.

ABSTRACT

Experimentally induced lead poisoning especially under simultaneous iron deficit leads to the development of secondary thiamine insufficiency. Erythrocyte riboflavin content and erythrocyte glutathion reductase and aspartate aminotransferase activities have been demonstrated to be increased. Lead treatment is accompanied with the increase of urinary excretion of riboflavin, 4-pyridoxic acid and 1-vtthylnicotinamide in rats fed with adequate diet. Thus lead intoxication and iron deficiency influence vitamin B group metabolism.

ABSTRACT

There was no differences of principle in vitamin status of population living in 'zones of strict control' (Brjanskaja, Mogilevskaja, Gomel'skaja regions) and Moscow's population. Mean indices of vitamin C, A, E, B1 and carotene status in children and adults were not differed in two groups of population. But vitamin B2 and niacin status in Moscow's adults were worse. Among children from Moscow vitamin C deficiency was found more rare and vitamin E deficiency more often than those in population from regions suffering from Chernobyl. It was established that supplement of third dishes with vitamin C is not sufficient for elimination of vitamin C deficiency. Polyvitamin pills 'Duovit' or premix 'Roche' were more effective in removal vitamin deficiency.

ABSTRACT

The investigation into the relationship between the concentration of vitamins B, the blood activity of vitamin B-dependent enzymes and the urinary excretion of their metabolites in 14 children of both sexes whose age was 4.5-10 years and who suffered from celiac disease has characterized their metabolic features. The criteria for vitamin B1 provision of these children differ from those in healthy children of the same age: the normal value of TDP effects is achieved with higher thiamine excretion which is more than 12 micrograms/h. Apparently, the plasma concentration of riboflavin greater than 14 ng/ml and its urinary excretion 6 micrograms/h should be taken as a criterion for normal vitamin B2 provision. Though due to a small proportion of the examined children, criteria for vitamin B6 and nicotinic acid could not be defined. The excretion of 4-pyridoxylic acid in the whole concentration ranges of pyridoxylic coenzymes in the plasma of sick children was essentially lower than that in healthy persons.

ABSTRACT

The investigations carried out in 1983-1993 showed increasing of insufficiency of vitamin C and carotene in population of almost all investigated areas of Russian Federation. Insufficiency of vitamin C was found in 70-95%, pronounced deficit in 45-70% of adults. Deficiency of carotene was was detected in 30-90% of adults. Insufficiency of these nutrients is unfavourable long condition detected not only during spring but also in summer in different occupational groups of population. Vitamins A and E nutritional status of different groups of population are good enough in all seasons.

ABSTRACT

Correlation between the state of vitamin metabolism and the impairments in carbohydrate, lipid and protein metabolism was studied in 35 children of 9-13 years of age with diabetes mellitus of various severity standing for up to 7 years. Deterioration of riboflavin metabolism in insulin-dependent diabetes mellitus, expressed as an increase of the vitamin excretion with urine, was augmented with prolongation of the disease duration; the deterioration was sometimes related to the value of glycemia and glucosuria, being the indicative symptom of the disease. In spite of some limitations in validity of experiments related to insufficient number of children in some groups, a decrease in excretion of 1-methyl nicotinamide with urine was detected in all the children with the comatose state, in acidoketosis and glucosuria (above 20 g/day), whereas normal content of nicotinamide coenzymes was found in erythrocytes. Deficiency in vitamins B1, B6 and C was observed more often (5-100%) in children with elevated content of cholesterol as compared with 7-67% of children exhibiting normal level of cholesterol. Optimization of vitamins B and C consumption in children as well as use of any means for correction of these vitamins deficiency are discussed.
