Scientists closely monitored various biological responses of people sequentially eating vegan and keto diets for two weeks, in random order. They found that the vegan diet prompted responses linked to innate immunity\u2014the body\u2019s non-specific first line of defense against pathogens\u2014while the keto diet prompted responses associated with adaptive immunity\u2014pathogen-specific immunity built through exposures in daily life and vaccination. Metabolic changes and shifts in the participants\u2019 microbiomes\u2014communities of bacteria living in the gut\u2014were also observed. More research is needed to determine if these changes are beneficial or detrimental and what effect they could have on nutritional interventions for diseases such as cancer or inflammatory conditions.<\/p>\n<p>Scientific understanding of how different diets impact the human immune system and microbiome is limited. Therapeutic nutritional interventions\u2014which involve changing the diet to improve health\u2014are not well understood, and few studies have directly compared the effects of more than one diet. The keto diet is a low-carbohydrate diet that is generally high in fat. The vegan diet eliminates animal products and tends to be high in fiber and low in fat.<\/p>\n<p>The study was conducted by researchers from the NIH\u2019s National Institute of Allergy and Infectious Diseases (NIAID) and National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) at the Metabolic Clinical Research Unit in the NIH Clinical Center. The 20 participants were diverse with respect to ethnicity, race, gender, body mass index (BMI), and age. Each person ate as much as desired of one diet (vegan or keto) for two weeks, followed by as much as desired of the other diet for two weeks. People on the vegan diet, which contained about 10% fat and 75% carbohydrates, chose to consume fewer calories than those on the keto diet, which contained about 76% fat and 10% carbohydrates. Throughout the study period, blood, urine, and stool were collected for analysis. The effects of the diets were examined using a \u201cmulti-omics\u201d approach that analyzed multiple data sets to assess the body\u2019s biochemical, cellular, metabolic, and immune responses, as well as changes to the microbiome. Participants remained on site for the entire month-long study, allowing for careful control of the dietary interventions.<\/p>\n<p>Switching exclusively to the study diets caused notable changes in all participants. The vegan diet significantly impacted pathways linked to the innate immune system, including antiviral responses. On the other hand, the keto diet led to significant increases in biochemical and cellular processes linked to adaptive immunity, such as pathways associated with T and B cells. The keto diet affected levels of more proteins in the blood plasma than the vegan diet, as well as proteins from a wider range of tissues, such as the blood, brain and bone marrow. The vegan diet promoted more red blood cell-linked pathways, including those involved in heme metabolism, which could be due to the higher iron content of this diet. Additionally, both diets produced changes in the microbiomes of the participants, causing shifts in the abundance of gut bacterial species that previously had been linked to the diets. The keto diet was associated with changes in amino acid metabolism\u2014an increase in human metabolic pathways for the production and degradation of amino acids and a reduction in microbial pathways for these processes\u2014which might reflect the higher amounts of protein consumed by people on this diet.<\/p>\n<p>The distinct metabolic and immune system changes caused by the two diets were observed despite the diversity of the participants, which shows that dietary changes consistently affect widespread and interconnected pathways in the body. More study is needed to examine how these nutritional interventions affect specific components of the immune system. According to the authors, the results of this study demonstrate that the immune system responds surprisingly rapidly to nutritional interventions. The authors suggest that it may be possible to tailor diets to prevent disease or complement disease treatments, such as by slowing processes associated with cancer or neurodegenerative disorders.<\/p>\n<h3>Article<\/h3>\n<p>VM Link <em>et al.<\/em> <a rel=\"noopener\" target=\"_blank\" href=\"https:\/\/www.nature.com\/articles\/s41591-023-02761-2\">Differential peripheral immune signatures elicited by vegan versus ketogenic diets in humans<\/a>. <em>Nature Medicine<\/em> DOI: 10.1038\/s41591-023-02761-2 (2024).<\/p>\n<h3>Who<\/h3>\n<p>Yasmine Belkaid, Ph.D., former chief of the NIAID Laboratory of Host Immunity and Microbiome, now president of the Institut Pasteur, Paris, France, is available to discuss this research.<\/p>\n<p>Kevin Hall, Ph.D., chief of the Integrative Physiology Section in the NIDDK Laboratory of Biological Modeling is also available to discuss this research.<\/p>\n<p>NIAID conducts and supports research\u2014at NIH, throughout the United States, and worldwide\u2014to study the causes of infectious and immune-mediated diseases, and to develop better means of preventing, diagnosing and treating these illnesses.
