How Does Your Diet Affect your Gut Microbiome? GutMicrobiome Diet Nutrition
Probiotics and the microbiomeThe diet plays a huge role in the composition of the microbiome, which varies considerably between vegetarian and mostly meat-eating communities and individuals. The Westernized diet causes a shift in the gut microbiome profile from that found in agrarian communities in Africa, for instance.
Dietary changes and the GMB A major change in diet leads to a large alteration in the composition of the GMB within just a day. Once the new diet is stopped, however, the pattern reverts within 48 hours. With high amounts of beef or other animal protein in the diet, the GMB is enriched in anerobic bacteria such as Bacteroides, Alistipes, Bilophila and Clostridia, but lower Bifidobacterium adolescentis, compared to strict vegetarians.
Saturated fats are associated with a higher abundance of Faecalibacterium prausnitzii. Conversely, a low-fat diet increases Bifidobacterium abundance, causing lower fasting glucose and total cholesterol levels. These fat-related changes are also linked to metabolic inflammation, and insulin sensitivity.

It is difficult to sustain over the long term due to the rigid restrictions on multiple plant-based foods. Conversely, the specific carbohydrate diet has been around for over a hundred years.
Probiotics and the microbiome Microbes that can be ingested to improve gut health and prevent or treat IBD are often found in fermented foods like yogurt and cultured milk and are called probiotics. These microbes affect the GMB to modulate inflammation. Notably, they bring about an increase in Bifidobacteria and/or Lactobacilli, with reductions in coliforms and total, very low density and low-density cholesterol.
The Mediterranean diet has a beneficial fatty acid profile, due to its composition rich in whole grains and legumes, nuts, fruits and vegetables, seafood, poultry, olive oil, and wine, and little red or processed meat, sweets, and dairy products. It is correlated with increases in SCFAs and higher levels of beneficial LAB, Bifidobacterium, Prevotella and Firmicutes, with reductions in Clostridia.

Selenium deficiency and scurvy due to an imbalanced diet of snacks and lacto-fermenting drinks: a case report of a 7-year-old boy with autism spectrum disorder - BMC NutritionBackground There have been reports of isolated trace elements or vitamin deficiencies due to imbalanced diets, but no cases of selenium deficiency combined with scurvy have been reported. Case presentation A 7 year-old boy diagnosed with autistic spectrum disorder and mild psychomotor retardation, started an imbalanced diet including specific snacks and lacto-fermenting drinks from 5 years of age. Gingival hemorrhage and perioral erosions occurred at 6 years and 8 months of age, and he was referred to our hospital at 7 years of age. Slight tachycardia was found. Serum vitamin C level was 1.1 µg/dL (reference range (rr): 5–17.5 µg/dL), and selenium level was 2.8 µg/dL (rr: 7.7–14.8 µg/dL). He was diagnosed with both selenium deficiency and scurvy. Multivitamins and sodium selenate were administered for 12 days during admission, and symptoms of selenium deficiency and scurvy improved. After discharge, symptoms abated following the administration of multivitamins and regular administration of sodium selenate every 3 months. Conclusions We report a complicated case of both selenium deficiency and scurvy due to an imbalanced diet of snacks and lacto-fermenting drinks in a 7-year-old boy with autism spectrum disorder. In patients with imbalanced diet, regular blood tests including trace elements and vitamins are necessary.
