Nutritional Value of Canned Olives

For most produce, when we compare the canned olives against fresh, there isn’t a great deal of difference in the macronutrients – fat, protein, and carbohydrates.

However, an average serving of canned olives is about 5 olives or 30 grams which has 35 – 70 calories. These calories are just enough to add a little bit of flavor to your diet without having to worry about your waistline.

Canned Olives are the Source of Iron

Canned olives provide nutritional value thanks to the iron properties. Women need at least 6 percent of iron in their diet, while men need at least 14 percent of iron in their diet. Each quarter-cup serving provides enough iron which is the required amount for both women and men in any diet.

Iron helps in transporting oxygen around your bloodstream. Apart from transporting oxygen, iron has other nutritional benefits. It helps to detect whether your body has low oxygen levels, and it fixes before you experience tissue damage. Iron is essential for immune function and supports energy production.

Disadvantage – Too Much Sodium

If canned olives are cured in a salt brine, one major negative aspect is that they may contain too much sodium (salt in other words).

Sodium is an electrolyte mineral that aids balance fluids in your body. While you need sodium in your balanced diet, too much sodium intake does give any benefits to your body and regular consumption may cause increased blood pressure.

One ounce (28 grams) of canned black olives (which is about 5 Kalamata olives) can provide up to 209 milligrams of sodium, which is 14 percent of the daily value adult needs according to the National Academy of Science report.

This is the reason why you need to take canned olives in moderation and don’t go extreme. So are canned olives good for you? Without a doubt, is you consume them in balance while adding to your food is no harm at all – it only provides required minerals to your body. Also, when buying canned olives, check their labels and avoid those with excess added salt.

Canned Olives Processing

The tinning olive process will vary slightly depending on the olive variety and ripeness but essentially the olives are washed and prepared, for example, branches or leaves are removed from olives, olives may be pitted or with a pit before being blanched.

Then, these fruits are placed into a sterilized can or tin and covered with brine usually made with salty water or special brine with seasoning added upon a taste.

Olive fruits are tinned close to where they are picked in order to help preserve their freshness and nutrients as much as possible. Or olives are kept in buckets for a couple of weeks to remove bitterness.
