Health Benefits Of Kalamata Olives
1. May Promote Skin Health
Olives have been an integral part of many skin care regimes for the visible benefits they offer. Oleuropein, a phenolic component in olives, is found to protect the skin from chronic UVB-induced damage. It also acts as a free radical scavenger (2).
This graph from a study published in Antioxidants (Basel) reveals that Kalamata olives contain high amounts of phenolic content. Though the CdN table olives were the richest in phenolic compounds, with a TPC equal to 13.08 mg/g DW, Kalamata olives showed a high content of phenols (10.84 mg GAE/g DW) compared to the other five commercially available olives covered in the study.

Therefore, including Kalamata olives in your diet may improve your skin health.
2. May Reduce The Risk Of Cancer
Kalamata olives are rich in polyphenols, antioxidants, and flavonoid compounds. These compounds shield the cells and cell membranes from free radical or external damage and potentially help in cancer prevention. Besides, the oleuropein in these olives may also hinder the viability of cancer cells (2), (3).
3. May Promote Cardiovascular Health
The oleuropein in Kalamata olives has been shown to reduce the risk of coronary heart disease and promote heart health. Studies suggest that it may protect against acute adriamycin cardiotoxicity (damage to the heart muscle). It was also found to inhibit the oxidation of low-density lipoproteins (LDL), also known as bad cholesterol (2),(3).
4. May Aid In Weight loss
Olives have powerful antioxidants and help maintain HDL cholesterol levels. Olive intake may also inhibit LDL development, which may aid in healthy weight management. These factors may hinder unwanted weight gain (3). However, more concrete research is warranted to understand how Kalamata olives may help with weight loss in humans.
5. May Help Manage Diabetes
The glycemic index of Kalamata olives is low (they digest very slowly), and they prevent the sudden release of sugars into the blood. One Kalamata olive (4 grams) provides 1 to 3 mg of hydroxytyrosol (a oxidative stressi XAn imbalance in the body between the production of free radicals and antioxidant abilities that can lead to cell damage and other symptoms like chronic fatigue. .” ]) (4). Hydroxytyrosol has insulini XA peptide hormone released by the pancreas in the body that is responsible for regulating glucose in the blood. -like effects and had shown significant anti-diabetic properties in animal models of type 2 diabetes. Moreover, it has protective effects against oxidative stress, inflammation, hyperglycemia (high blood sugar), and hyperlipidemia (high fat levels in blood).
Besides, the European Food Safety Authority has approved the use of hydroxytyrosol (5 mg/day) to prevent oxidative damage and inflammation, reducing the risk of insulin resistance/diabetes (5). However, more quality research is warranted to understand the role of Kalamata olives in diabetes control.
6. May Combat Inflammation
The antioxidant compounds in olives effectively combat free radicals. This helps prevent harmful oxidative damage to cells and effectively combat inflammation and may also help improve brain function (6). These anti-inflammatory properties can be attributed to the polyphenol content in olives (7). However, olive oil is more clearly studied for this benefit than olives directly. So, detailed research on the consumption of Kalamata olives and their role in combating inflammation is warranted.
In Greece, olives are very sacred and a huge part of their culture. The goddess Irene was shown carrying an olive branch to symbolize peace. And to claim the city of Attica (present day Athens), goddess Athena was believed to have planted an olive tree so the people would have food, oil, and wood.
7. May Lower Blood Pressure
Table olives are packed with cardioprotective bioactive compounds such as oleic acid, polyphenols, and pentacyclic triterpenes. A study was conducted to evaluate the effect of table olives on blood pressure levels of spontaneously hypertensive rats (SHR) and Wistar Kyoto (WKY) rats. The findings revealed that while the olives did not affect the blood pressure of WKY rats, they significantly reduced the blood pressure levels in SHR rats. The analysis also detected polyphenols and oleanolic acid in the rat’s plasma as contributing to lower blood pressure levels. These results indicate that daily consumption of table olives may help in blood pressure management (8). However, further studies are warranted in this regard.
These benefits of Kalamata olives are far-reaching. But, what makes these olives one of the healthiest foods to consume? Let’s explore the reasons in the following section.
