Better Digestion, Regular Bowel Movements

The fiber (both soluble and insoluble) in oats speeds up digestion. Bloating is diminished, bowel movements are easier and gut health overall feels better within weeks for most people.

Improved All-Day Blood Sugar Balance

Your body absorbs oats slowly, so you’re less likely to experience peaks and crashes in blood sugar. This is conducive of stable energy, lower irritability, and ideal for people with insulin resistance.

Lower LDL (“Bad”) Cholesterol Levels

Fiber compound beta-glucan attaches itself to cholesterol in the gut, enabling it to be excreted. In a month, most people see better heart health measurements and lower levels of LDL.

Increased Satiety and Reduced Cravings

The fiber and protein combo helps you feel fuller for longer. This in turn limits mindless snacking and leads to a decrease in consumption of sugary or processed foods without dieting stringently.

Gradual Weight Management Benefits

Eating oats every day can help to promote weight loss and support healthy digestion, as they are a slow digesting food which helps you feel fuller for longer, making it less likely to want to snack. They’re not a rapid weight-loss food, but help keep things moving at a manageable pace.

Enhanced Gut Microbiome Health

Oats are prebiotic, feeding the good bacteria living in our digestive systems. A balanced microbiome is integral to proper digestion, mood stability, immunity support and inflammation control.

Having oats ready to go makes for nice meals and minimizes decision fatigue. This helps create a more positive relationship with feeding, routine and daily nutrition.
