Foods That Boost Your Immune System Naturally - Dr. Neal Barnard Live Q\u0026AFat intake and immune system -
The peritoneal MØ of the exercised mice were stimulated with fluorescent microspheres and showed decreased phagocytosis in exercised mice fed linseed oil, but there was no effect of FO.
Then 3. typhimurium was given orally. Kew et al. The standard diet had 4. The authors showed that EPA decreased monocyte phagocytosis when it was in the sn-1 3 position of dietary TAG, but not the sn-2 position, relative to the control 25 vs.
EPA increased MFI mean fluorescence intensity for monocytes in the sn-2 position, relative to the control diet vs. The proliferation index was decreased for mice monocytes on feeding on 4. EPA also decreased neutrophil phagocytosis when it was in the sn-1 3 position Also, MFI was decreased for neutrophils from mice provided with EPA in the sn-1 3 position, relative to the control vs.
Moreover, 4. There was no effect of DHA. The authors suggested that the sn-1 3 orientation of EPA increased the fluidity of the phagocyte cell membrane.
The lack of effect of DHA in this study was explained by the authors based on DHA conformation because it functions contrary to the membrane-fluidizing impact due to its chain length and a high degree of unsaturation, whereas EPA increases membrane fluidity In a study by Hubbard et al.
Results showed no effect of diet on peritoneal MØ stimulated with zymosan and sheep RBCs. One in vivo study showed increased phagocytic activity after FO feeding Zymosan was injected into the peritoneal cavity 1 h before sacrifice.
The results showed that FO increased the proportion of MØ involved in phagocytosis: FO also increased the mean number of particles ingested per MØ vs.
BO, and CO 4. The weights for spleen and thymus increased considerably by DHA In macrophages, there was enhanced propagation and phagocytosis in the prevention and cure groups due to DHA. Also, DHA activated macrophages by G protein—coupled cell membrane receptor GPR—Mitogen-Activated Protein Kinases MAPKs —nuclear factor κB NF-κB p65 metabolism in vivo.
In the spleen, DHA activated the proliferation of spleen cells and NK cells in vivo. The data for real-time PCR qRT-PCR revealed the production of cytokines IL-1β, IL-2, TNF-α, and IFN-γ in the spleen of immunosuppressive mice due to the presence of DHA.
These findings are indicative of the immunomodulatory activity of DHA on immunosuppressive mice model in prevention or cure groups Liu and Leung 65 studied the effects of jacaric acid, a conjugated linolenic acid CLNA isomer obtained from jacaranda seed oil on murine peritoneal macrophages.
Their findings revealed that jacaric acid showed no significant cytotoxicity on murine peritoneal macrophages but increased cytostatic activity of T cells. Analyses by flow cytometry showed that jacaric acid enhanced the endocytic activity of macrophages.
Also, there was an upregulation of pro-inflammatory cytokines such as interferon-γ, interleukin-1β, and tumor necrosis factor-α, thus showing that jacaric acid could exert an immunomodulatory effect on murine peritoneal macrophage cells in vitro.
Gram-positive bacteria like Staphylococcus aureus play a major role in this infection. Antibiotics are used to counter this problem which has led to resistance by these bacteria.
The activation of neutrophils is triggered as a defense mechanism against such bacterial infections. Studies have revealed that mice when fed high-fat dietary rations HFDs rich in PUFAs HFD-P have a higher frequency of neutrophils than mice fed HFDs rich in saturated fatty acids HFD-S.
N-3 PUFA metabolites called resolvins can enhance neutrophil capacity to phagocytose E. The existence of mice was improved by diet with resolving D2 RvD2. It was further investigated to check if HFD rich in omega-3 or mega-6 FAs is more effective at enhancing survival and lowering bacterial existence in mice with septic S.
aureus —induced infection. The results showed that HFD-ω3—fed mice had higher survival rates than those fed HFD-ω6 or HFD-s, and there was a reduction in bacterial loads as well. In addition, HFD-S—fed mice also have a reduced frequency of phagocytosing neutrophils in their circulation.
These findings showed that mice fed n-3 PUFAs have better ability to survive sepsis which is very likely due to an increase in neutrophils and precursor cells in the bone marrow and a restored phagocytic ability Numerous studies show the beneficial aspects of n-3 PUFAs in an inflammatory response in animals for acute and chronic inflammatory reactions, especially in the brain.
Some studies in rodent models have shown that the resolvins, RvD1, and RvE1 show anti-inflammation in the CNS. RvD1 lowers the stimulation of NFκB and the production of elements involved in pro-inflammation such as IL-1β, IL-6, TNF-α, and iNOS in rats with hemorrhagic shock or streptozotocin-stimulated diabetic retinopathy.
RvD1 reduces neuroinflammation by the ALX-FPR2 receptor through miRNA in a neonatal hypoxia—ischemia rat model.
It also stimulates the accumulation of macrophages and microglia in the direction of M2 phagocytes. Persistent and early RvD1 supplementation in a rat modeling for Parkinson's disease can stop central and peripheral inflammatory responses.
RvE1 helps reduce pro-inflammatory cytokines IL-1β and IL-6 in the prefrontal cortex and also in a murine model of Alzheimer's disease. It further regulates the stimulation of microglia by enhancing ramified microglia after traumatic brain damage.
High concentrations of RvD1 in the brain in Fat-1 mice are associated with fewer cognitive defects, a decrease in microglial activation, and pro-inflammation due to high n-3 PUFAs in the brain during brain ischemia Data from rat studies were reviewed to study the influence of n-3 PUFA on phagocytic activity ex vivo and in vitro.
There was one in vitro study which showed no effect of unsaturated FAs on phagocytosis of peritoneal macrophages in vitro Overall, ex vivo dietary rat studies showed that n-3 PUFAs either increase or have no effect on phagocytosis.
Four studies showed increased phagocytosis 68 — 71 and four studies showed no effect of PUFA on phagocytosis 72 — One study showed that n-3 PUFA decreased phagocytosis in rats Cukier et al. They were administered six varied types of oral isocaloric 1.
The rats were killed 96 h after TPN or saline infusion. The results showed that no significance was observed for liver, spleen, or lung weights. The non-lipid TPN inhibited macrophage phagocytosis of the spleen and lungs. The lipid TPN supplemented with fish oil emulsion showed a rise in total liver and lung macrophages.
Thus, indicating that TPN supplemented with fish oil enhanced phagocytosis in rats. In the study of Bonatto et al. Female Wistar rats were supplemented with 1 g per kg body weight of either coconut oil or FO. This experimental treatment was repeated for two consecutive generations. the control and coconut oil groups in the non—tumor-bearing rats.
No influence was observed in the tumor-bearing rats De Nardi et al. No effect was observed in the spleen. Engels et al. Miyasaka et al. In the study by Palombo et al. In the study of Bulbul et al.
It was observed that DHA decreased the mean number of phagocytized particles per macrophage vs. corn oil, 6. N-3 PUFAs have previously shown to be effective in reducing tumor growth, particularly EPA and DHA derived from FO.
These FAs present in the diet can alter the functions of the tumor and immune cells. The results showed that innate immune cells enhanced phagocytic capacity and increased processing and removal of antigens.
It was also observed that there was a reduction in the production of pro-inflammatory cytokines [tumor necrosis factor-alpha TNF-α and interleukin 6 IL-6 ] by macrophages.
Thus, oil rich in ALA showed similar immune modulation in cancer when compared with FO Kaveh et al. ALA also had a preventive effect on inflammatory markers and tracheal responsiveness. In recent times, the importance of identifying physiologically functional ingredients in ruminant milk and dairy yields for their nutraceutical and health benefits and also to meet the rising consumer demand has gained the attention of researchers worldwide.
Enhancing the milk FA profile is an innovative strategy to further enhance the physiological and nutritional characteristics of ruminant milk for benefiting animals and humans. Ruminant diets are generally low in lipid content. Studies have established that objects provided with fresh forages and grazing grass yield milk with a greater content of PUFAs in comparison with those animals fed fodder.
Lipid supplements have been found to modulate the acid composition of milk effectively. Omega-3 anti-inflammatory and immunomodulatory abilities have been made use of in the study on animals to produce animal resources characterized by specific nutraceutical properties.
Many past kinds of research have been done in vitro and in vivo to evaluate the immunomodulation of supplementary n-3 PUFAs in goats.
To elaborate on a few, goats supplemented with FO diets during their transition period showed skin feedback to a phytohemagglutinin PHA skin challenge after kidding, thus showing high levels of cell-mediated immunity. Circulating lymphocytes were found to be high which also proved that FO was effective.
On the other hand, corn oil supplementation lowered the expression of CD49d α-4 integrin —a subsection of leukocyte homing receptors that change tissue-specific cell metabolic pathways.
In vitro studies analyzed the function of leukocyte in fat-supplemented goats. It was observed that neutrophils taken from dairy goats generated fewer ROS when administered doses 25, , μM of DHA, but not of EPA. A very low dosage 25 μM stimulated neutrophil phagocytic activity.
Similarly, another study in goat monocyte-isolated cells showed that phagocytic activity was the highest for low to intermediate levels of EPA 25— μM and only intermediate levels of DHA μM , whereas greater levels of both EPA and DHA proved to be ineffective and also detrimental on cultured monocyte cells as showcased by expansion in caspase-7 and caspase-3 pro-apoptotic activity Farina and colleagues also previously reported studies that showed dietary FO ingested by transition dairy goats was beneficial to cell-mediated immune function.
DHA from FO caused an increase in PMN phagocytic activity and lowered ROS production in vitro and under in vivo conditions when the effects of EPA and DHA were studied; it showed that goat health improved by the action of neutrophils and thus prevented damage at the cellular and tissue levels by ROS.
EPA and DHA also influenced goat monocytes by the upregulation of phagocytosis and ROS making by interfering with lipid droplet development and upregulating proteins of the PAT protein family Caroprese et al. also took up a study to assess diets supplemented with FO and linseed oil on the immune profile of 24 Garganica grazing goats.
They analyzed the in vivo immune responses by monitoring cell-mediated and humoral immune responses to check for the effects of PUFAs. Linseed milk showed lower SFA and higher PUFA than FO milk. Linseed and FO administration lowered humoral immunity but did not affect cellular immunity.
Dietary linseed supplementation in grazing goats resulted in modulation of immune responses During the transition phase in Holstein cows, supplementation with SO induced a pro-inflammatory state indicated by the enhanced neutrophil expression of adhesion molecules, synthesis of cytokines, increased bactericidal action, and enhanced circulating acute-phase proteins.
Supplementation with FO after 35 days post partum dpp stimulated an anti-inflammation that was demonstrated by the attenuation of neutrophil cytokine manufacturing. SO is a fat fortifier rich in LA; it can lower the threshold for triggering an immune action that changes innate immunity.
This pro-inflammation might be suitable for coping with the hectic and greatly contaminated postpartum period. Conversely, FO can enhance the threshold for triggering an immune action throughout the breeding period, exerting an anti-inflammatory status that might weaken the immune functions in early pregnancy upon environmental triggers i.
Silvestre et al. This was done as an attempt to promote immune response during the transition by using n-6 FAs compared with n-3 FAs. The percentage of neutrophils with phagocytic and oxidative burst activities was not influenced by transition diets, but activities per neutrophil were higher in SO, relative to PO diets at 4 phagocytosis and oxidative burst and 7 dpp oxidative burst.
This enhancement in phagocytosis of bacteria by neutrophils could be a result of the enhancement of n-6 precursors of eicosanoids or a decrease of anti-inflammatory n-3 FAs. This study also revealed an enhancement in plasma concentrations of two acute-phase proteins; this also revealed that the liver was inflamed during this period.
This influence of neutrophils and acute-phase proteins was thought to enhance the immune response and in turn decrease infection; however, it is still unclear if this would be beneficial for a transition cow Didara et al.
He reported that marked immune suppression was observed during the periparturient period in Holstein cows. Hence, dietary n-3 FAs along with oxidative stress contributed to the reduced cellular immunity throughout the periparturient period.
A total of 45 Holstein cows were fed diets that consisted of a blend of Ca salts of fish, safflower, and palm oils to make three different proportions of n-6 to n-3 FA; namely, 3.
Phagocytosis and oxidative burst by neutrophils harvested from circulation were unaffected by dietary feed ration in the first 48 h after intramammary LPS infusion. Feeding Holstein cows more n-3 and less n-6 FA in their dietary feed ration attenuated the acute-phase response after the intramammary challenge with lipopolysaccharide LPS , although the diet did not reduce losses in intake and production during the inflammatory challenge The results obtained by Gandra et al.
In addition, an increase of expression of adhesion molecules in response to PUFA supplementation suggests a proinflammatory effect of PUFA in transition dairy cows.
The n-3 FA appears to have a greater influence on phagocytic capacity and activity of leukocytes than n-6 FA. The n-3 and n-6 FAs may be an effective tool to encourage inflammation of transition cows wherein omega-3 supplementation repressing inflammation to promote productivity and omega-6 supplements to improve immunity and reduce infectious diseases.
Researchers must continue to pursue the best strategy to address challenges in farms Constant research in ruminant lipid metabolism along with knowledge on the action of FAs has led to their use in modulation of animal products like enhancing the unsaturated FA content.
A careful selection of lipid sources should be taken into consideration when supplementing it into the diets to enrich the acidic content of milk.
At the same time, the inhibitor effect of PUFAs on ruminal metabolism has been seen in the reduction of milk fat content MFD. This phenomenon is lesser in goats than in sheep and cows. To enhance the efficacy of PUFAs in milk, a worthy approach could be using rumen-protected or rumen-inert fat complements.
Dietary fats show modulation related to metabolic, inflammatory, and immune functions, via direct action on receptors and transcription factors and via their bioactive oxygenated metabolites as well. The immunomodulatory activity of fats showing improved functionality in goats is clear.
An assumption can be made for the beneficial effects of PUAs on host defense from non-specific immune stimuli during metabolic and immune stress during the peripartum phase. Molecular analyses have shown to be evasive and thus ineffective in recognizing relationships between supplementary diets and inflammatory agents and immunity-related genes In ruminants, milk FA composition can be improved through their nutrition which in turn has a positive impact on human health through the consumption of dairy products enriched in omega-3 FAs and LA.
Omega-3 FAs have proven to modulate immune and inflammatory response in dairy ruminants. Feeding pregnant animals with these bioactive FAs can impact its progeny health status.
Dietary long-chain PUFAs can also affect changes in lipid metabolism gene network in organs such as liver, adipose tissue, and mammary gland and temporal modulation on lipid metabolism The maximum productivity of lactating animals can be obtained by regulating energy content and resources.
Ewes supplemented with PUFAs in the form of palm oil showed improvement in the number and sizes of pre-ovulatory follicles, ovulation rates, conception, and lambing rates.
So a study used 30 multiparous lactating ewes Rahmani × Barki to examine the effects of two dietary supplemental energy sources on their metabolic attributes, milk production, and ovarian activity of ewes during early to mid-postpartum period. They were given diets supplemented with palm oil or sugarcane molasses.
The results showed that both energy sources lowered body weight. Overall, this fat supplementation increases serum triglycerides which provided energy sources for enhancing milk productivity. The fatty acid profile also boosted the quality of the ovulatory follicle and the ovulation process Hashem and El-Zarkouny 90 examined the effects of short-term supplementation with rumen-protected fat of 76 Rahmani, Barki, and Awassi × Barki during late luteal phase on reproduction and metabolism.
They concluded that short-term supplementation with rumen-protected fat helped to improve metabolism, conception, and lambing rates of ewes during breeding.
Dietary FAs and their by-products have an impact on human health and health outcomes. The study of dyslipidemia by lipidomic analysis showed that SFAs and n-6 PUFA are inflammatory in nature.
The rise in diseases like type II diabetes, nervous system diseases, cardiovascular disorders, and atherosclerosis associated with unhealthy diets has led to the significance of lipid homeostasis in health and disease. N-3 and n-6 FAs are essential FAs as the body is not able to synthesize them.
N-3 FAs are anti-inflammatory, whereas n-6 FAs are pro-inflammatory. The conversion of AA to inflammatory mediators by COX-2 gives rise to resolution and therefore EPA and DHA generate pro-resolution lipids. Also, these FAs alter signaling pathway recognition receptors and G protein—coupled receptors GPR40 on lymphocytes, which in turn decreases inflammatory risks in the case of cardiovascular disorders.
LC-PUFA metabolites, otherwise known as eicosanoids, interact with GPCRs and have been related to the development of atherosclerosis. Intake of dietary omega-3 FAs offers precursors for the synthesis of anti-inflammatory lipids called leukotrienes such as LTB 5 and prostanoids PGH 3 whereas a rise in n-6 PUFAs produces LTA 4 , LTB 4 , LTC 4 , LTD 4 , LTE 44 , and PGH 2.
The primary inflammatory response in the human body, characterized by the synthesis of LTB 4 , is essential for neutrophil infiltration to the infection site and then proceeds with a cascade of cytokine production.
These bioactive derivatives are incorporated into the membrane phospholipids and influence membrane fluidity and surface receptor expression. There are some studies on the inclusion of FAs into the cell membrane of macrophages as seen in activated polymorphonuclear neutrophils PMNs where there is a loss of PUFAs as a result of the very high intracellular phospholipase activity cPLA2 due to leukocyte stimulation Since the 's, it has been well-known that preventing the lipoxygenase metabolism of inflammation inhibits the differentiation of monocytes to macrophages after administration of AA.
Fortification of cells with n-3 FAs like linolenate FA n-3 stimulates a faster immunity by decreasing TNF-alpha in contrast to macrophages fortified with n-6 FAs like LA, depending on macrophage development.
The classically activated pro-inflammatory M1 macrophages are rich in LTB4 and PGE2 whereas M2 macrophages are rich in pro-resolving mediators from the 5-lipoxygenase pathway 5-LOX and eicosanoids from n-3 FAs like EPA and DHA such as resolvin D2 and D5 RvD2, 5.
Some in vitro studies in humans showed decreased phagocytosis after exposure to n-3 PUFAs. Sipka et al. In the same study, the authors investigated plasma membrane fluidity by labeling of neutrophils with propionic acid during EPA addition.
In non-stimulated neutrophils, EPA enhanced the flexibility of cell membranes. Conversely, in zymosan-activated cells, there was a small period of fluidization after which EPA resulted in a significant rigidification of the plasma membrane. This rigidification was explained by the authors to be an explanation for the reduced phagocytic activity and chemotaxis of human neutrophils.
Versleijen et al. Dietary intake in humans has been suggested to alter the human ability to synthesize LC-PUFA essential C18 FA precursors, i.
However, these studies in general show little evidence of an influence of n-3 PUFA on phagocytic activity. Seven studies showed no effect 93 — 99 , two studies showed a detrimental effect , , and one study showed enhancement of phagocytosis after feeding n-3 PUFA In the study of Schilling et al.
coli by PBMCs. Halvorsen et al. Similarly, Thies et al. Results of the phagocytosis test showed no effect of supplementation on phagocytosis of PMBCs enhanced with opsonized FITC-labeled E. coli In the study of Miles et al.
Rees et al. Exceptionally, two studies showed decreased phagocytosis , In the study of Virella et al. Margaro et al. To date, evidence in humans has shown that anti-inflammatory effects of n-3 PUFAs were first recognized in epidemiological studies in Eskimos as they consumed a lot of fish which is rich in n-3 LC-PUFAs.
Some clinical studies showed the positive influence of n-3 LC-PUFAs in chronic inflammatory and autoimmune diseases. FO decreased pro-inflammatory cytokine expression such as IL-1β in blood monocytes and enhances the symptoms of patients suffering from rheumatoid arthritis or multiple sclerosis.
DHA reduced circulatory inflammatory markers and oxidative stress. It also helped patients with moderate cognitive alterations The appearance of atherosclerotic lesions as a trigger due to an increase in concentrations of cholesterol-rich lipoproteins is distinguished by inflammatory conditions.
Of late, it was seen that blocking pro-inflammatory metabolic pathways without altering lipid concentrations can decrease the danger of heart disorders. A diminished vascular inflammatory response is a critical factor in atherosclerosis, and the production of pro-resolving lipid mediators is considered as a defensive mechanism against murine atherosclerosis.
Hence, an investigation was started to further explore the metabolic pathways associated with EPA fortification and synthesis of lipid mediators that mediate atherosclerotic disease progression.
Studies in the literature revealed that fortification with EPA significantly weakened atherosclerotic lesion growth caused by western diet in these mice and was linked with cardiovascular n-3 PUFA supplementation and charged lipoprotein The anti-inflammatory properties of n-3 PUFA are a result of their ability to inhibit the production of inflammatory mediators such as eicosanoids PGE 2 , 4-series leukotrienes , pro-inflammatory cytokines IL-1β, TNF-α, IL-6 , chemokines IL-8, MCP-1 , adhesion molecules ICAM-1, VCAM-1, selectins , platelet-activating factor, and reactive oxygen and nitrogen species.
Besides inhibition of pro-inflammatory mediators, n-3 PUFA can increase the production of an anti-inflammatory cytokine such as IL The anti-inflammatory action of n-3 PUFA is governed by modulation of gene activation. This gene activation is regulated by nuclear factor-kappa B NF-κB , a transcription factor ubiquitous in almost all cell types.
One of the striking characteristics concerning n-3 research is the discovery of pro-resolution agents by serving as the precursors for several families of pre-resolving mediators, which at least include EPA-derived E-series resolvins, DHA-derived D-series resolvins, and DHA-derived protectins and maresins.
Limited data are surrounding human immunomodulatory and anti-inflammatory actions of resolvins and maresins Dietary PUFAs play a role in innate and adaptive immunity as described in in vitro studies and animal models.
However, from a clinical point of view, the results obtained are uncertain as many diseases in humans are dependent on genetic and environmental factors.
In addition, experimental techniques to analyze the effects of FAs on immune responses lack clarity and give varying results. The doses utilized in in vitro and in vivo studies are not in line with physiological concentrations in biological fluids and tissues PUFAs have been a topic of interest since the late 's.
This area of research falls into different categories, predominantly in humans. Although the information in this area is extensive, there are significant gaps and inconsistencies in studies to be able to come to a firm conclusion.
A reason for this could be the variation in responses in a population or other factors like dietary components, sex, experimental species, age, body composition, and genetics.
These factors have been currently researched with advancements in analytical and statistical technologies. Focus is mostly put on EPA and DHA studied in combination and not as two separate entities.
It is well-known by now that fish and FO are rich sources of n-3 PUFA. However, the supply of fish for human consumption is not sustainable and thus alternate sources are being researched such as algal oils and seed oils N-6 PUFA is less significant and is mostly used as the control for n-3 PUFA in studies.
ALA, DHA, and EPA mostly exert an inhibitory effect on the activation of immune cells from innate and adaptive immunity. Some specialized immune functions are promoted by dietary omega-3 FAs in certain immune cells, such as phagocytosis by macrophages and neutrophils or Treg differentiation which indicates that omega-3 FAs do not act as unspecific immune repressors.
Varying data from numerous studies give rise to different approaches for the incorporation of FAs in in vitro cellular cultures, for example, differences in enrichment doses or incubating time, length of fortification time, etc.
Reports on mouse models may vary with that in humans as both species are different immunologically and at the metabolic level. Fortification of n-3 FAs in human diets have lesser concentrations of EPA and DHA and are present for a shorter duration period than in mouse experiments.
Also, mouse diets are controlled by the researchers whereas the human diet is complicated and varied 1. Based on the aforementioned, dietary PUFAs may or may not modulate the immune system by affecting phagocytosis. Care should be taken when these FAs are supplemented to ensure the general health.
The effect of FAs on murines either showed a lowering effect on phagocytosis or had no effect. In ruminants, the n-3 FAs seem to have a significant influence on phagocytosis. Overall, in humans, most studies showed no effect except a few, which points in the direction of more in-depth research.

However, since a high level of fat was thought to be immunosuppressive, the researchers sought to determine if increasing dietary fat would compromise various elements of the immune system, while improving performance.
The study involved six female and eight male competitive runners who trained at 40 miles a week and were part of a larger performance study. They spent a month on their normal diets, followed by a month each on diets composed of approximately 17 percent, 32 percent and 41 percent fat.
Protein remained stable at 15 percent and carbohydrates made up the difference. The immune status of the runners was obtained by analyzing concentrations of essential components of the immune system -- leukocytes, cytokines and plasma cortisol -- in blood samples taken before and after an endurance exercise test.
The tests were conducted at the end of each four-week diet period. Results showed that natural killer cells, a type of leukocyte and one of the body's defense mechanisms marshaled to fight infection, were more than doubled in runners after the high-fat diet, compared to the low-fat regimen.
Levels of PGE2, inflammation-causing prostaglandins, increased after the endurance test and were higher when the runners were on the low-fat diet. This study is part of a larger investigation to determine the effects of dietary fat on performance, biochemical and nutritional status, and plasma lipids and lipoprotein profiles in distance runners being conducted by a study group composed of -- in addition to Venkatraman and Pendergast -- Peter Horvath, Ph.

Blood glucose regulation iterg. Received: 20 August Accepted: 10 January The untake and optimal functioning of ahd immune system is directly influenced by our diet. Any deficiency or excess Energy-boosting meals certain nutrients immuune affect the Energy-boosting meals and activity of immune cells. Among the nutrients identified, dietary fatty acids are described as having major effects on immunity. Indeed, the fatty acid composition of the membranes of immune cells seems to be easily modulated under the effect of dietary fats and the resulting rapid changes in composition are likely to generate functional effects on the reactivity and functioning of these cells within a very short period of time.
