Comparative Study Of Commercial Food Antigen Extracts For The Diagnosis Of Food Hypersensitivity

Single lots of food allergen extracts from three different commercial sources were compared for their efficacy in evaluating immediate food hypersensitivity. Eighty-seven children with atopic dermatitis and food hypersensitivity underwent prick skin testing to a battery of 18 food extracts from each company. Results of skin tests were compared with results of double-blind, placebo-controlled oral food challenges and open challenges to determine the sensitivity, specificity, and predictive indices of each reagent. Negative predictive indices were generally good for all reagents, whereas positive predictive indices were generally poor and showed considerable variation between commercial sources. Under the conditions of the study, skin test reagents from two companies showed slightly better agreement with double-blind, placebo-controlled food challenge results than did reagents from the third company. However, with known lot-to-lot variations in extract potency and intrapatient variation in skin test results, these differences probably are not of clinical significance.

Fad Diets Can Cause Health Problems

Because they often cut out key foods, fad diets may cause the following symptoms:

• Dehydration.
• Constipation.
• Inadequate vitamin and mineral intake.

Fad diets that severely restrict food groups or nutrients may also mean that you miss out on the protective health effects that a balanced eating plan provides. We don’t know whether fad diets are safe over the longer term, or whether they lead to an increased risk of various diseases.

A Closer Look At Water

Water-soluble vitamins are packed into the watery portions of the foods you eat. They are absorbed directly into the bloodstream as food is broken down during digestion or as a supplement dissolves.

Because much of your body consists of water, many of the water-soluble vitamins circulate easily in your body. Your kidneys continuously regulate levels of water-soluble vitamins, shunting excesses out of the body in your urine.

Water-soluble vitamins

• Folic acid
• Niacin

Vitamin C

Vitamin D Functions And Health Benefits

Vitamin D refers to a group of fat-soluble vitamins derived from cholesterol. Vitamins D2 and D3 are the only ones known to have biological actions in the human body. The skin synthesizes vitamin D when exposed to sunlight. In fact, for most people, more than 90 percent of their vitamin D3 comes from the casual exposure to the UVB rays in sunlight. Anything that reduces your exposure to the suns UVB rays decreases the amount of vitamin D3 your skin synthesizes. That would include long winters, your homes altitude, whether you are wearing sunscreen, and the color of your skin . Do you ever wonder about an increased risk for skin cancer by spending too much time in the sun? Do not fret. Less than thirty minutes of sun exposure to the arms and legs will increase blood levels of vitamin D3 more than orally taking 10,000 IU of vitamin D3.

A Closer Look At Major Minerals

The body needs, and stores, fairly large amounts of the major minerals. These minerals are no more important to your health than the trace minerals theyre just present in your body in greater amounts.

Major minerals travel through the body in various ways. Potassium, for example, is quickly absorbed into the bloodstream, where it circulates freely and is excreted by the kidneys, much like a water-soluble vitamin. Calcium is more like a fat-soluble vitamin because it requires a carrier for absorption and transport.

Effect Of Low Dose Vitamin K2 Supplementation On Bio

It has been reported that treatment with a pharmacological dose of menaquinone-4 prevents bone loss in postmenopausal women. However, it is not known whether supplementation with low dose MK-4 has beneficial effects on bone metabolism in healthy women. The aim of this study is to examine the effects of the supplementation of 1.5 mg/d MK-4 for 4 wk on bone and lipid metabolism in healthy postmenopausal Japanese women. The study was performed as a randomized double blind placebo-controlled trial. The participants aged 53-65 y were randomly assigned to 2 groups and supplemented with 1.5 mg/d of MK-4 or a placebo for 4 wk . The most marked effects of MK-4 intake were observed on serum osteocalcin concentrations. Serum undercarboxylated OC concentration decreased, and the gamma-carboxylated OC and GlaOC/GlaOC+ucOC ratio that indicates the degree of OC gamma-carboxylation increased significantly at 2 and 4 wk compared with that at baseline in the MK-4 group. The serum ucOC and GlaOC concentrations in the MK-4 group were significantly different from those in the placebo group at 2 wk. These results suggest that supplementation with 1.5 mg/d MK-4 accelerated the degree of OC gamma-carboxylation. The concentrations of serum lipids and other indices were not different between the groups at either intervention period. Thus, the additional intake of MK-4 might be beneficial in the maintenance of bone health in postmenopausal Japanese women.

Vita Regulation Of B Cell Activity

Antigen stimulation of immune cells through specific IgE antibodies results in a rapid, specific hypersensitivity response that is involved in most autoimmune conditions . Evidence shows RA has an IgE-repressive activity in vivo. The inhibitory effect of ATRA on IgE mainly downregulates synthesis and secretion of IgE through RARα, and this inhibitory effect depends on IL-10 . Another report shows that exogenous 9-cis-RA in the context of an allergic sensitization profoundly modulates an established humoral IgE response, resulting in reduced specific IgE responses and increased specific IgA responses in mice, indicating that RXR-activating retinoids play a major role in the physiological regulation of IgE due to the endogenous synthesis of 9-cis-RA . These make VitA a very promising therapy for the treatment of IgE-mediated hypersensitivity disease.

Interactingin Good Ways And Bad

Many micronutrients interact. Vitamin D enables your body to pluck calcium from food sources passing through your digestive tract rather than harvesting it from your bones. Vitamin C helps you absorb iron.

The interplay of micronutrients isnt always cooperative, however. For example, vitamin C blocks your bodys ability to assimilate the essential mineral copper. And even a minor overload of the mineral manganese can worsen iron deficiency.

Manifestations Of Food Allergy: Evaluation And Management

The term food allergy refers to adverse immunologic reactions to food. Food allergy is usually mediated by IgE antibody directed to specific food proteins, but other immunologic mechanisms can also play a role. The primary target organs for food allergic reactions are the skin, the gastrointestinal tract and the respiratory system. Both acute reactions and chronic disease may be caused or exacerbated by food allergy. The foods most commonly causing these reactions in children are milk, egg, peanuts, soy, wheat, tree nuts, fish and shellfish in adults, they are peanuts, tree nuts, shellfish and fish. The diagnosis of food allergy requires a careful search for possible causes, confirmation of the cause with supporting tests, including specific tests for IgE and, in some cases, oral food challenges. Treatment consists of elimination of the causal food along with medical treatment, including the prompt self-administration of epinephrine in the event of a serious reaction.

Effects Of Vita On Immunoglobulin Production

Antibody production by B cells is central to humoral homeostatic maintenance. Antibodies represent a specific class of immunoglobulins. Animal experiments have demonstrated that the addition of carotenoid-rich foods to rabbit diets can increase their serum levels of IgG, IgM, and IgA, thereby enhancing humoral immunity . Further studies in rat have revealed the association between a paucity of VitA in the diet and increased number of DCs, in addition to the significantly upregulated expression of IL-12, Toll-like receptor 2, and myeloid differentiation factor MyD88 in the intestinal mucosa. When the levels of secretory IgA decrease, rats display a decreased immune function, suggesting that VitA is involved in the synthesis of immunoglobulins, and has an important influence on humoral immunity . A report shows that RA potently synergized with gut-associated lymphoid tissues DC-derived IL-6 or IL-5 to induce IgA secretion . A knockout study demonstrated that the ablation of RARα reduces IgA expression by B cells expressed in vivo and in vitro. This indicates that RA acts on B cells directly through RARα, which affects the synthesis and secretion of IgA . It is also likely that RA affects Tregs first, and then indirectly modulates B cells, since Tregs have an important role in regulating B cell responses .

Vitamin K1 Supplementation Retards Bone Loss In Postmenopausal Women Between 50 And 60 Years Of Age

Although several observational studies have demonstrated an association between vitamin K status and bone mineral density in postmenopausal women, no placebo-controlled intervention trials of the effect of vitamin K1 supplementation on bone loss have been reported thus far. In the trial presented here we have investigated the potential complementary effect of vitamin K1 and a mineral + vitamin D supplement on postmenopausal bone loss. The design of our study was a randomized, double-blind, placebo-controlled intervention study 181 healthy postmenopausal women between 50 and 60 years old were recruited, 155 of whom completed the study. During the 3-year treatment period, participants received a daily supplement containing either placebo, or calcium, magnesium, zinc, and vitamin D , or the same formulation with additional vitamin K1 . The main outcome was the change in BMD of the femoral neck and lumbar spine after 3 years, as measured by DXA. The group receiving the supplement containing additional vitamin K1 showed reduced bone loss of the femoral neck: after 3 years the difference between the MDK and the placebo group was 1.7% and that between the MDK and MD group was 1.3% . No significant differences were observed among the three groups with respect to change of BMD at the site of the lumbar spine. If co-administered with minerals and vitamin D, vitamin K1 may substantially contribute to reducing postmenopausal bone loss at the site of the femoral neck.

fats

Answers

Answer:The nutritional class that contributes to the absorption of vitamins and supports the immune system are fats.Explanation:Fats are of fundamental importance to the body, since they form the cell membranes and participate in the synthesis of hormones, among other functions, as the absorption of vitamins and contribute to the immune function.- Fats are capable of absorbing certain types of vitamins, specifically A, D, E and K, called liposoluble vitamins, which can be stored in the adipose tissue.- The immune system depends on fats in the first place because they constitute the first line of defense of the cells, since they constitute the cellular membrane of selective permeability.Additionally, immune defense cells use the function of the cellular membrane to facilitate the reception and presentation of antigens, secretion of antibodies and toxic substances for foreign organisms, such as cytokines and lymphokines, among others.Regarding the other options:Water is necessary for homeostasis maintenance, substance transport and waste disposal.Proteins constitute the structural and functional support of living organisms, by building tissues and participating in metabolic and regulatory functions.Carbohydrates are the main energy source of living beings.
