Why eat 30 plant foods a week?💚🌿
Guidance to eat 30 different plant foods p/w, is based on American and British Gut Project* research; one of the largest studies on the human microbiome.
⚡It found that people consuming a greater variety of plant-based foods had more diverse and healthier gut microbiomes, linked to better digestion, immunity, and overall health.
⚡The study indicated that eating around 30 plants per week seems optimal. This is on basis:
🌿for those eating more than 30 plants, findings indicated gut
health benefits began to plateau (more research needed on this though); and
🌿a sizeable number of participants achieved intake of 30 plant foods
⚡The study compared differences in gut health between those eating 30 or more plant foods and those eating 10 or less.
⚡Results indicated much greater diversity of gut microbes (lots of different species) in the group eating 30+ plant foods p/w.
⚡More plant foods mean a wider range of prebiotic fibres, phytochemicals and polyphenols, which feed different gut bacteria. These bacteria are vital to break down and utilise all components of our nutrient intake.
Lots of microbes are fussy and thrive on specific foods. So the wider the range of plant foods you eat, the greater the diversity🥦 🥑 🥕
💚Research links high diversity of microbes to lower risk of diseases such as diabetes, depression, heart disease, obesity, dementia, as well as autoimmune conditions and allergies.
How to hit 30 plants p/w:
✅Count fruits, vegetables, whole grains, legumes, nuts, seeds, herbs, spices and unrefined oils (extra virgin /cold pressed)
✅Try new foods – rotate your grains (include quinoa, farro, millet, teff), legumes (chickpeas, beans, lentils), and expand your range of vegetables
✅Use as many herbs and spices as possible
✅Aim to include mixed dishes like salads, soups and stir-fries
☝️Bottom line: Eating a wide variety of plant foods nurtures a thriving gut environment, supporting long-term health.
☝️If you can go higher than 30, do it!😊
