They are the cornerstone of the Mediterranean diet, a savory garnish in martinis, and a divisive topping on pizza. But when you reach for that jar in the fridge, you might find yourself asking: Are olives healthy?
The short answer is a resounding yes, but with a salty caveat.
Olives are technically a stone fruit (drupe), related to peaches and cherries, yet they are treated as a savory vegetable in the culinary world. For thousands of years, they have been celebrated not just for their rich flavor but for their medicinal properties. From heart-healthy fats to powerful antioxidants, the benefits of olives are extensive.
However, modern processing methods have introduced a complication: sodium. Most olives found in supermarkets are cured in brine, turning a naturally bitter fruit into a salty snack. This leads to conflicting advice. Are they a superfood or a sodium bomb? Are olives fattening?
Can you eat them every day? In this comprehensive guide, we will dissect the truth about how healthy olives are. We will analyze their nutritional profile, compare green vs. black varieties, investigate their impact on weight loss and heart health, and answer once and for all: Are olives healthy for you?
Is it ok to eat olives everyday?

Olives Nutrition Profile: What Makes Olives Healthy?
To understand why are olives healthy, we must look beyond the taste and into the biochemistry. Olives are nutrient-dense powerhouses, but their composition is unique compared to other fruits.
Calories & Fat Breakdown
Unlike apples or bananas, which are high in sugar and carbs, olives are high in fat.
- Calories: A standard serving (about 10 olives) contains roughly 50–60 calories. This makes them a low-calorie snack if you stick to the serving size.
- Carbs: They are incredibly low in carbohydrates (less than 1g per serving) and high in fiber, making them keto-friendly.
- Fat: About 80-85% of the calories in olives come from fat. But this isn’t the fat found in a cheeseburger; it is primarily oleic acid, a monounsaturated fatty acid (MUFA) linked to reduced inflammation.
Vitamins & Minerals
When asking olives are nutritious, the answer lies in their micronutrients:
- Vitamin E: Olives are one of the best plant-based sources of Vitamin E, a potent antioxidant that protects cells from oxidative damage.
- Iron: particularly high in black olives, iron is essential for red blood cell function and energy.
- Copper: A trace mineral vital for heart health.
- Calcium: Often absorbed from the brine, contributing to bone health.
Polyphenols & Antioxidants
This is the “secret weapon” of the olive. They are packed with bioactive compounds, specifically Oleuropein (responsible for the bitter taste in fresh olives) and Hydroxytyrosol.
- Research shows: These antioxidants fight inflammation, protect blood vessel linings, and may even have anti-cancer properties.
Summary: Are olives a healthy food? Yes. They provide essential healthy fats, fiber, and disease-fighting antioxidants in a low-calorie package.
Are Olives Healthy Fats or Fattening?
In the low-fat craze of the 90s, olives were demonized. Today, we know better. But the question remains: Are olives healthy fats or will they make you gain weight?
Monounsaturated Fats: The Good Guys
The fat in olives is primarily monounsaturated fat. This is the same type of fat found in avocados and nuts.
- Heart Health: MUFAs are proven to lower LDL (bad) cholesterol while maintaining or raising HDL (good) cholesterol.
- Satiety: Fat digests slowly, keeping you fuller for longer. This is why olives are good for you as a snack—they curb hunger pangs better than a sugary fruit or a dry cracker.
Are Olives Fattening?
Are olives fattening? Technically, any food is fattening if eaten in excess. Fat contains 9 calories per gram (compared to 4 calories for carbs/protein).
- The Reality: Because olives are so flavorful and rich, it is difficult to overeat them to the point of massive calorie surplus compared to hyperpalatable processed foods like chips.
- Portion Control: Eating 10 olives provides ~50 calories of healthy fat. Eating a whole jar provides ~500+ calories. As long as you don’t treat them like popcorn, they are not fattening.
Are Olives Heart Healthy?
The Mediterranean diet is consistently ranked the #1 diet for heart health, and olives are its star player. Are olives heart-healthy? Absolutely.
Cholesterol & Inflammation
Chronic inflammation is a key driver of heart disease. The oleic acid and antioxidants in olives act as natural anti-inflammatories.
- Oxidation: Cholesterol becomes dangerous when it oxidizes in your arteries. The Vitamin E and polyphenols in olives prevent this oxidation process, effectively acting as a shield for your heart.
Blood Pressure Considerations
This is the double-edged sword.
- The Good: The polyphenols in olives can improve endothelial function (the health of blood vessel walls), potentially lowering blood pressure.
The Bad: The salt. Are olives healthy for someone with hypertension? If you are salt-sensitive, the high sodium content of canned olives could counteract the benefits. However, washing the olives or buying low-sodium versions can mitigate this risk.

Are Olives Healthy to Eat Every Day?
You love them. You want them daily. But are olives healthy to eat every day?
Safe Daily Portions
Is it okay to eat olives daily? Yes, for most healthy adults.
Nutritionists generally recommend a serving size of 5 to 10 olives per day.
This amount provides the anti-inflammatory benefits and healthy fats without overloading your system with sodium or excessive calories.
The Sodium Caveat
If you eat a handful of olives every day, you must account for the salt in the rest of your diet. If you are eating processed deli meats and frozen dinners, adding olives might tip you over the recommended daily sodium limit (2,300mg). If you eat a mostly whole-food diet, a daily serving of olives is perfectly safe.
Best Times to Eat Olives
How many olives should I eat a day and when?
- Pre-Dinner: In Mediterranean cultures, olives are served as an aperitivo. The fat stimulates appetite-suppressing hormones, potentially stopping you from overeating the main course.
- Afternoon Slump: The fat provides steady energy, avoiding the crash associated with sugary snacks.
Are Olives Too Salty? Sodium & Health Concerns
We cannot ignore the elephant in the brine. Are olives too salty?
Why Are Olives Brined?
Fresh olives off the tree are inedible. They contain incredibly high levels of oleuropein, making them intensely bitter. To make them palatable, they must be “cured.”
- Curing Methods: Brine (saltwater), dry salt, lye, or oil.
- The Consequence: The olive absorbs the salt.
Are Olives High in Sodium?
Yes. Are olives naturally salty? No, the salt is added.
- Sodium Count: 5 black olives contain about 115–200mg of sodium.
- Comparison: That is roughly 5–8% of your daily limit in just 5 small bites.
Side Effects of Eating Olives
If you overindulge, the side effects of eating olives relate to sodium:
- Bloating and water retention.
- Thirst.
- Temporary spike in blood pressure (for salt-sensitive individuals).
How to Reduce Sodium
If you are worried about olives are healthy due to salt:
- Rinse Them: Rinsing olives in fresh water before eating can remove up to 30% of the surface sodium.
- Buy “Low Sodium”: Many brands now offer reduced-salt varieties.
- Oil-Cured: Some specialty olives are cured in oil or dried, which may have different sodium profiles (check labels).
Pros and Cons of Olives
Let’s summarize the pros and cons of olives to see the big picture. Are olives healthy or unhealthy?
The Pros (Benefits)
- Heart Health: High in monounsaturated fats (oleic acid).
- Antioxidant Power: Rich in Vitamin E and polyphenols.
- Anti-Inflammatory: Reduces oxidative stress.
- Diet Friendly: Low carb, Keto, Paleo, Vegan, and Gluten-Free.
- Bone Health: Good source of calcium (depending on processing).
The Cons (Downsides)
- High Sodium: Can cause bloating or BP issues.
- Calorie Density: Easy to over-consume calories if not measured.
- Acrylamide: Some canned black olives contain trace amounts of acrylamide (a byproduct of high-heat processing), though levels are generally considered safe.
Summary Table: Who Should Eat Them?
| Eat Freely (in moderation) | Limit Intake |
| Keto/Low Carb Dieters | People with High Blood Pressure |
| Vegans/Vegetarians | Those on a Low-Sodium Diet |
| People seeking heart health | People prone to kidney stones (high oxalate/sodium concerns) |

Are Olives a Healthy Snack?
Forget potato chips. Are olives a healthy snack?
Satiety & Satisfaction
Are olives healthy snacks? Yes, they are one of the best savory snacks available.
Most savory snacks (crackers, chips, pretzels) are refined carbohydrates that spike blood sugar and leave you hungry an hour later. Olives provide fat and fiber, which stabilize blood sugar and keep you full.
Olives vs. Chips
- Chips (1 oz): ~150 calories, 15g carbs, low nutrients, inflammatory seed oils.
- Olives (10 large): ~50 calories, 1g carb, high antioxidants, healthy fruit oil.
Verdict: Olives win every time.
Healthy Snack Pairings
To make a balanced mini-meal:
- Olives + Feta Cheese: Protein and fat.
- Olives + Almonds: Crunchy texture and extra fiber.
- Olives + Hummus/Veggies: A complete fiber-rich platter.
Are Olives Healthy for Weight Loss?
If you are trying to shed pounds, are olives healthy for weight loss?
Calorie Density vs. Nutrient Density
While fats are calorie-dense, olives are unique. Because they have a high water content (unlike nuts), their calorie density is lower than you might think. You can eat 10 olives for the same calories as one Oreo cookie.
Appetite Control
The MUFAs in olives trigger the release of cholecystokinin, a hormone that signals fullness.
Tip: Eat 5 olives 20 minutes before a meal. This “appetizer” effect can take the edge off your hunger, helping you eat a smaller portion of your main meal.
Conclusion: Are olives good for weight loss? Yes, used as a tool for satiety and flavor substitution (replacing cheese or bacon with olives), they are excellent.
Are Olives Healthy for Diabetics?
For the millions managing blood sugar, are olives healthy for diabetics?
Glycemic Index: Zero
Olives have an extremely low glycemic index (GI) and glycemic load because they contain almost no sugar or starch.
- Blood Sugar: Eating olives will not spike blood glucose.
- Insulin Sensitivity: The oleic acid in olives may help improve insulin sensitivity, making it easier for your body to process glucose.
Best Olive Choices for Diabetics
Diabetics often need to watch their heart health (BP) as well. Therefore, low-sodium olives or thoroughly rinsed olives are the best choice to protect the cardiovascular system while enjoying the blood-sugar benefits.
Are Olives Healthy for Pregnancy & Females?
Craving pickles and olives is a pregnancy cliché, but are olives healthy for pregnancy?
Folic Acid & Iron
Are olives healthy for females? Yes.
- Pregnancy: Olives contain small amounts of folate (crucial for fetal development) and good fats for baby’s brain growth.
- Iron: Pregnant women have higher iron needs; black olives are a good plant-based source.
Sodium Caution
However, pregnancy often comes with swelling (edema) and risk of pre-eclampsia (high blood pressure). Because olives are high in sodium, pregnant women should enjoy them in moderation to avoid worsening water retention.
The Myth of Cravings
If you are constantly craving olives, it might be your body asking for sodium (increased blood volume requires electrolytes) or healthy fats. It is generally safe to indulge the craving within reason.
Are Olives Healthy for Skin & Beauty?
We put olive oil on our skin, but are olives healthy for skin when eaten?
Vitamin E and “Glow”
- UV Protection: The Vitamin E in olives acts as an internal sunscreen, protecting skin cells from UV radiation and premature aging.
- Hydration: The healthy fats help maintain the skin’s lipid barrier, keeping it hydrated and plump.
- Antioxidants: Hydroxytyrosol fights free radicals that cause wrinkles.
Verdict: Eating olives contributes to the “Mediterranean Glow.”
Green Olives vs Black Olives: Which Are Healthier?
You’re at the olive bar. You see bright green Manzanillas and dark wrinkly Kalamatas. Which are healthier green or black olives?
Ripeness & Processing
The difference is mainly ripeness.
- Green Olives: Picked before they are fully ripe. They are firmer and more bitter, requiring longer brining.
- Black Olives: Picked when fully ripe. They are softer and oilier.
- Note on “Canned Black Olives”: The generic black olives in cans (California style) are actually green olives that have been treated with lye and oxygen to turn them black.
Nutrition Comparison
Are green olives healthy? Yes.
Are black olives healthy? Yes.
- Fat Content: Black olives (being riper) usually have slightly more oil/fat than green olives.
- Sodium: Green olives are often saltier because they are naturally more bitter and need stronger brine.
- Nutrients: Black olives tend to be higher in iron. Green olives tend to be higher in Vitamin E.
The Verdict
How healthy are black olives compared to green ones? The difference is negligible. Choose based on taste and sodium content. If you want less salt, a ripe, naturally cured black olive is often a better bet than a sharp, salty green one.
Detail Comparison: Green vs. Black Olives
When you’re standing at the olive bar, does the color really matter? Here is the cheat sheet to help you choose.
| Feature | Green Olives (Manzanilla, Picholine) | Black Olives (Kalamata, Mission) |
| Harvest Time | Picked UNRIPE (Early harvest) | Picked FULLY RIPE (Late harvest) |
| Texture | Firm, meaty, dense. | Soft, oily, tender. |
| Flavor Profile | Bitter, tangy, sharp, nutty. | Rich, mild, earthy, slightly sweet. |
| Fat Content | Moderate Fat (approx. 10-15%). | Higher Fat (approx. 15-20%) due to ripeness. |
| Sodium | Higher. Needs more salt to cure bitterness. | Lower. Naturally milder, so less salt is needed. |
| Best Nutrient | Higher in Vitamin E (Skin health). | Higher in Iron (Energy & blood health). |
| Processing | Often cured with lye (Spanish style) or brine. | Often oil-cured, brine-cured, or dry-salted. |
| Best For… | Martinis, stuffing (pimento/garlic), cheese boards. | Pizzas, salads, tapenades, pasta. |
The Verdict
- Choose Green if you want a lower-calorie snack with a crunchy bite and Vitamin E boost.
- Choose Black if you want lower sodium, softer texture, and higher healthy fat/Iron content.
Specialty Olives: Are They Healthy?
What about the fancy ones? Are Kalamata olives healthy? Are stuffed olives healthy?
Kalamata Olives
These Greek gems are deep purple, almond-shaped, and usually preserved in red wine vinegar and oil.
- Verdict: Very Healthy. They are rich in polyphenols (hence the purple color) and healthy fats. The vinegar adds probiotic potential if unpasteurized.
Stuffed Olives (Garlic, Pimento, Jalapeño)
Are garlic-stuffed olives healthy? Generally, yes. You get the added benefits of garlic (immune support) or peppers (metabolism).
- Watch Out For: Blue cheese or almond stuffings significantly increase the calorie count.
Spanish Olives (Manzanilla)
Are Spanish olives healthy? These are the standard green olives often stuffed with pimento. They are healthy, but usually the highest in sodium.
Marinated Olives
Are marinated olives healthy? Olives sold in oil and herbs are delicious, but the calorie count is higher because they are swimming in extra oil. Ensure the oil used is high-quality olive oil, not cheap soybean or canola oil.
Are Canned & Jarred Olives Healthy?
Most of us buy cans. Are canned black olives healthy? Or are olives from a jar healthy?
The “California Ripe” Olive (Canned)
These are the mild black olives on pizzas.
- Processing: Treated with lye (sodium hydroxide) to remove bitterness, then washed, then oxidized to turn black, then canned and heat-sterilized.
- Nutrition: They retain their iron and fat, but the lye processing destroys some of the delicate polyphenols found in naturally cured olives.
- Safety: BPA in can linings used to be a concern, but many manufacturers have switched to BPA-free cans.
Jarred Olives
Olives in glass jars are typically cured in brine or vinegar.
- Verdict: Generally healthier than canned because they often undergo less industrial processing (like lye baths) and retain more antioxidants.
Which Olives Are the Healthiest?
If you want the absolute best option, which olives are healthiest?
- Naturally Cured / Sun-Dried: Look for olives cured in oil or dry-salted (Thassos olives). They often have concentrated nutrients.
- Kalamata: High in polyphenols and usually lower in harsh chemical processing.
- Low-Sodium Varieties: Essential for heart health.
- Organic: To avoid pesticide residues, though olives are generally not on the “Dirty Dozen” list.
Avoid: Canned olives that list “Ferrous Gluconate” (color stabilizer) if you are looking for purely natural foods, though it is considered safe.
Are Olives Healthy? Reddit, Myths & Public Opinion
