<\/p>\nThe aroma of freshly baked sourdough has made its way from artisanal bakeries to home kitchens across Kolkata. But beyond its crisp crust and tangy flavour, the centuries-old bread is increasingly being recognised for its nutritional benefits.<\/p>\n
Unlike conventional bread, sourdough is made using a starter of flour and water that ferments naturally over several days. During this process, wild yeast and beneficial bacteria develop, eliminating the need for artificial preservatives and commercial yeast. Fermentation also lowers the bread’s glycaemic index, helping reduce sudden spikes in blood sugar levels.<\/p>\n
According to Sraboni Mukherjee, chief dietician, Fortis Hospital Anandapur, \u201cSourdough bread is often considered a healthier alternative to regular commercial white bread because of its natural, slow fermentation process. During fermentation, wild yeast and beneficial lactic acid bacteria work together to break down the carbohydrates and proteins in the dough partially.\u201d<\/p>\n
The slower fermentation process also improves the body’s ability to absorb essential minerals such as iron, zinc, magnesium and selenium by reducing phytic acid, a compound that limits nutrient absorption. Experts say this makes sourdough nutritionally superior to refined white bread.<\/p>\n

\n Authentic sourdough is made with just flour, water, salt, and a natural starter, while commercial bread often contains sugar, oil and preservatives\n <\/p>\n
Digestive health is another reason many people are making the switch. Fermentation partially breaks down gluten and starches, which may make sourdough easier to digest. <\/p>\n
\u201cMany people without celiac disease find that sourdough is gentler on their digestive system than regular white bread,\u201d says Mukherjee.<\/p>\n
Research and anecdotal evidence suggest that some people experience less bloating and abdominal discomfort after eating sourdough. The fermentation process also creates resistant starch, which reaches the large intestine and nourishes beneficial gut bacteria.<\/p>\n
The differences between sourdough and regular bread extend beyond health. <\/p>\n
Authentic sourdough is made with just flour, water, salt, and a natural starter, while commercial bread often contains sugar, oil and preservatives. Sourdough typically takes 12 to 48 hours to ferment, compared with the 1 to 2 hours required for regular bread.<\/p>\n
Debalina Dutta, manager of Dietetics Department, CK Birla Hospital CMRI, believes that sourdough has a nutritional edge over conventional bread. \u201cFrom a nutritional point of view, sourdough bread is better than conventional bread,\u201d she says.<\/p>\n
\u201cFermentation lowers the glycaemic index of sourdough bread, helping to prevent spikes in blood sugar levels. It is a better option for people managing diabetes or insulin resistance. It helps to release minerals like iron, zinc, and magnesium from the flour; it also reduces phytates and other compounds that can bind to minerals and hamper their absorption,\u201d added Dutta.<\/p>\n

Dietitian Jayati of AM Medical Centre says there are several notable differences between sourdough bread and regular bread. <\/p>\n
\u201cFrom both a health and digestion perspective, sourdough offers several advantages. The long fermentation process breaks down a significant portion of the gluten, proteins, and phytic acid present in the dough. As a result, sourdough is generally easier to digest than regular bread,\u201d said Jayati.<\/p>\n
Experts, however, caution that sourdough is not a miracle food. Portion control remains important, particularly for people with diabetes. Choosing whole-grain sourdough and checking the salt content can help maximise its benefits while keeping the diet balanced.<\/p>\n","protected":false},"excerpt":{"rendered":"The aroma of freshly baked sourdough has made its way from artisanal bakeries to home kitchens across Kolkata.…\n","protected":false},"author":2,"featured_media":630647,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[277],"tags":[18,135,19,17,508,115636,266405],"class_list":["post-630646","post","type-post","status-publish","format-standard","has-post-thumbnail","category-nutrition","tag-eire","tag-health","tag-ie","tag-ireland","tag-nutrition","tag-sourdough-bread","tag-sourdough-bread-benefits"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ie\/117072759303314140","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/630646","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=630646"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/630646\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/630647"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=630646"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=630646"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=630646"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
