Understanding the Nutrition Encyclopedia
A basic guide to reading the fruit and vegetable nutrition encyclopedia — how to choose, store, and get the most health benefits from every type of fruit and vegetable.
Why Do We Need a Fruit & Vegetable Encyclopedia?
Every day we eat fruits and vegetables, but rarely do we truly know what's inside them — what vitamins they contain, what benefits they provide, or the best way to prepare them so their nutrients aren't wasted. This encyclopedia was created to answer all of that, one by one, for the fruits and vegetables we encounter most often in daily life.
Each page contains four main sections: a brief explanation, nutritional content per 100 grams, health benefits, and the best ways to choose, store, and prepare them. The goal is simple — so you can eat more mindfully, not just to fill your stomach.
How to Read Nutritional Content
On each page, you'll find a nutritional content table per 100 grams of fresh ingredient. Here are a few things to keep in mind when reading it:

- The numbers are estimates — actual nutritional content can vary depending on variety, ripeness level, soil conditions, and storage method
- "Per 100 grams" doesn't mean a serving size — for example, one banana could weigh 120 grams, so adjust based on the actual weight
- Calories aren't the only thing that matters — also pay attention to fiber, vitamins, and minerals, which show how "nutrient-dense" an ingredient is
- Cooking method affects nutritional content — boiling vegetables for too long can dissolve vitamin C and B into the cooking water
Basic Principles for Consuming Fruits & Vegetables
- Color variety — the more diverse the colors of fruits and vegetables on your plate, the more complete the range of antioxidants and nutrients you get
- Prioritize fresh and seasonal produce — usually cheaper, fresher, and better preserved in nutritional content
- Don't peel off all the skin — many vitamins and fiber are actually concentrated right under the skin (for fruits/vegetables with edible skin that has been washed thoroughly)
- Combine ways of eating — some raw (salads, fresh vegetable sides, juice), some cooked (stir-fried, steamed, boiled) — some nutrients are more easily absorbed after cooking, while others are better preserved when raw
- Consistency matters more than perfection — eating fruits and vegetables regularly every day is far more beneficial than occasionally eating a lot at once
How to Choose Fresh Fruits & Vegetables
- Use all your senses — look at the color, feel the texture, and smell the aroma. Ripe fruit usually has a distinct aroma that you can smell without getting too close
- Avoid bruised or watery ones — a sign that spoilage has begun, even if the outside still looks fine
- Leafy vegetables should look fresh and upright — not wilted or yellowing at the edges
- Buy only what you need — the best fresh fruits and vegetables are consumed within a few days, not stored for weeks
How to Store So Nutrients Stay Preserved
- Leafy vegetables — store in the fridge in a container or perforated bag, and don't wash them until you're ready to use them (excess moisture speeds up spoilage)
- Unripe fruit — store at room temperature until ripe, then move it to the fridge to slow down further ripening
- Cut fruits and vegetables — store in an airtight container in the fridge and use within 1-2 days to preserve their vitamin C content
- Separate ethylene-producing fruits (such as apples and bananas) from leafy vegetables — this gas can speed up the spoilage of vegetables nearby
How Much Should You Consume?
World health organizations generally recommend consuming at least 400 grams of fruits and vegetables per day (excluding starchy tubers like potatoes), often simplified as "5 servings a day" — about 2 servings of fruit and 3 servings of vegetables. One serving is roughly equivalent to one medium-sized fruit, or one bowl of cooked vegetables.
