Onion (Allium cepa) is not just a staple in culinary traditions worldwide but also a valuable source of nutrition with numerous health benefits. One of the key components of onions are anthocyanins, which are high-value compounds known for their antioxidant properties. These compounds are instrumental in preventing neuronal diseases and exhibit a range of therapeutic effects, including anti-inflammatory, chemotherapeutic, cardioprotective, hepatoprotective, and neuroprotective activities.

Onions are particularly rich in these beneficial anthocyanins. Recent studies have focused on both conventional and improved methods for extracting these compounds, with improved methods showing higher yield and stability. This is crucial for maximizing the bioavailability and health benefits of anthocyanins.

In addition to anthocyanins, onions contain vitamins, carbohydrates, proteins, minerals, dietary fiber, and phenolic compounds. They have been found to have medicinal benefits like wound healing, growth inhibition of microbial and tumor cells, reduction of cancer risk, protection against cardiovascular diseases and diabetes, and anti-inflammatory properties.

Furthermore, onions have been shown to have a positive effect on lipid profiles, including improving levels of high-density lipoprotein cholesterol (HDL) and reducing low-density lipoprotein cholesterol (LDL). This makes them beneficial in the management of dyslipidemia. ^[32]

30: Kefir

Kefir, a fermented milk product, is increasingly recognized for its numerous health benefits, making it a valuable functional food. It is a natural complex containing more than 50 species of probiotic bacteria and yeast, offering a range of health-promoting properties. These include anti-obesity, anti-hepatic steatosis, antioxidative, antiallergenic, antitumor, anti-inflammatory, cholesterol-lowering, constipation-alleviating, and antimicrobial effects.

Kefir’s health benefits are largely attributed to its ability to modulate the host gut microbiota. It demonstrates excellent gastrointestinal resistance and colonization ability, along with a wide range of microbial interactions. This makes kefir effective in modulating both the gut microbiota and mycobiota. The association of this modulation with health benefits has been addressed in several studies, but further research is needed to fully understand the precise mechanisms.

Additionally, kefir has shown potential in promoting an increase in the number of bifidobacteria in the colon, improving glycemic control, reducing blood cholesterol, and balancing the intestinal microbiota. These effects contribute to reducing constipation and diarrhea, improving intestinal permeability, and stimulating and balancing the immune system. ^[33][34]
