Macronutrient Breakdown
NUTRITIONIST INSIGHT
Kosterina fermented olives deliver a rare combination of live probiotics and heart-healthy oleic acid in just 35 calories per serving. The year-long natural fermentation produces beneficial Lactobacillus strains that support gut microbiome diversity, while the polyphenol content (especially oleuropein) provides anti-inflammatory benefits you won't find in chemically processed table olives.
Myth Busters
MYTH #1: Olives Are Too High in Fat to Be Healthy
TRUTH: The fat in olives is primarily oleic acid, a monounsaturated fatty acid linked to reduced cardiovascular risk and improved cholesterol levels. Just 3g of fat per 5-olive serving, mostly heart-protective.
MYTH #2: All Olives Contain Probiotics
TRUTH: Only naturally fermented olives contain live probiotic cultures. Most store-bought olives are chemically processed with lye (NaOH), which kills beneficial bacteria. Kosterina olives are brine-fermented for up to 12 months, preserving Lactobacillus plantarum and L. pentosus.
MYTH #3: Fermented Olives Are Too Salty for Heart Health
TRUTH: While sodium is present (310mg per serving), the potassium and polyphenols in olives help counterbalance sodium's effects on blood pressure. Rinsing olives before eating reduces sodium by 40-50%.
MYTH #4: Olives Cause Weight Gain
TRUTH: At just 35 calories per serving, olives are one of the most calorie-efficient snacks. The healthy fats and fiber promote satiety and reduce overall calorie intake when replacing processed snacks.
MYTH #5: Canned and Fermented Olives Are the Same
TRUTH: Canned olives undergo chemical processing that destroys probiotics and reduces polyphenol content by up to 70%. Naturally fermented olives retain significantly more bioactive compounds and contain live beneficial bacteria.
