Sourdough is having a momentโฆ but itโs actually ancient.
๐ ๐ช๐ฎ๐ข๐๐ค ๐๐๐๐ญ๐ฌ ๐
โข It dates back to ancient Egypt (~3000 BC) โ one of the oldest forms of leavened bread ()
โข It relies on wild yeast + bacteria instead of commercial yeast
โข It was basically the way bread was made before modern baking
So why has it exploded again in the last 10 years?
Honestlyโฆ a mix of things:
โข Pandemic baking + slower living trends ()
โข People wanting more โartisanโ + less processed foods
โข And yeah โ the aesthetic doesnโt hurt
๐๐จ๐ฐ ๐ฅ๐๐ญโ๐ฌ ๐๐ฅ๐๐๐ซ ๐ฌ๐จ๐ฆ๐๐ญ๐ก๐ข๐ง๐ ๐ฎ๐ฉ:
๐ซ Sourdough is NOT a probiotic food.
The fermentation involves bacteria, but the heat from baking kills them โ so no live cultures in your toast ()
That saidโฆ still worth buying.
๐ ๐ซ๐๐๐ฌ๐จ๐ง๐ฌ ๐ญ๐จ ๐๐๐ ๐ข๐ญ ๐ข๐ง๐ญ๐จ ๐ฒ๐จ๐ฎ๐ซ ๐ซ๐จ๐ญ๐๐ญ๐ข๐จ๐ง:
โข Unique tangy flavour (instant upgrade from basic bread)
โข Better texture โ chewy inside, crispy crust
โข Fermentation can improve mineral availability + digestibility ()
Itโs not โhealth food magicโ โ itโs just really good bread with some perks.
๐ Try swapping your usual loaf for sourdough this week and see if you notice the difference.

Low vitamin D is more common than you thinkโand itโs rarely just one cause.
Here are the top key risk factors to watch for ๐
๐๐ ๐ฒ๐จ๐ฎ ๐ ๐๐ญ ๐ฅ๐ข๐ญ๐ญ๐ฅ๐ ๐ฌ๐ฎ๐ง (indoor lifestyle, winter, northern climates, or heavy sunscreen use), your body may struggle to make enough vitamin D.
๐๐๐ซ๐ค๐๐ซ ๐ฌ๐ค๐ข๐ง ๐ญ๐จ๐ง๐๐ฌ need more sun exposure, and aging reduces your skinโs ability to produce it.
๐๐๐ซ๐ซ๐ฒ๐ข๐ง๐ ๐๐ฑ๐ญ๐ซ๐ ๐๐จ๐๐ฒ ๐๐๐ญ? Vitamin D can get โtrapped,โ meaning you may need higher intake.

Other hidden factors include ๐ ๐๐ง๐๐ญ๐ข๐๐ฌ, ๐ ๐ฎ๐ญ ๐ข๐ฌ๐ฌ๐ฎ๐๐ฌ (like IBD or celiac), pregnancy, and ๐๐ก๐ซ๐จ๐ง๐ข๐ ๐๐จ๐ง๐๐ข๐ญ๐ข๐จ๐ง๐ฌ affecting the liver, kidneys, or hormones.
๐๐๐ซ๐ญ๐๐ข๐ง ๐ฆ๐๐๐ฌ (like steroids or anticonvulsants) can also interfere.

Goji berries arenโt just trendyโtheyโve been used for over 2,000 years in traditional Chinese medicine ๐ฟ
Originally from Asia (especially China and Tibet), these bright red berries were prized for supporting longevity, vision, and overall vitality.
But hereโs what makes them stand out today ๐
โจ Zeaxanthin powerhouse
Goji berries are one of the richest natural sources of zeaxanthinโa carotenoid that accumulates in the retina and helps protect your eyes from blue light and oxidative stress. Think: better long-term eye health and support against age-related vision decline.
โจ Antioxidant support
Theyโre loaded with vitamin C, polyphenols, and carotenoids to help fight inflammation and oxidative damage.
โจ Immune + skin benefits
The combo of antioxidants and trace minerals may support immune resilience and healthier skin.
๐ก Easy ways to use them:
Toss into oatmeal or yogurt
Add to trail mix
Blend into smoothies
Steep as a tea
Sprinkle on salads for a sweet-tart pop
Theyโre slightly sweet, a little tangy, and super versatile.
If youโre looking for a simple, food-first way to support eye healthโthis is a solid add.
