Guavas are a tropical fruit prized for their high vitamin C content and dietary fiber, but they also contain a small amount of fat — mostly from beneficial unsaturated fatty acids like linoleic acid. Whether you're tracking macronutrients for weight management, following a low-fat diet, or simply curious about the nutritional profile of your favorite fruit, this calculator helps you determine the exact fat content in any serving of guava.
Simply enter the weight of guava you plan to eat (in grams or ounces), and the tool will compute the total fat, saturated fat, and monounsaturated plus polyunsaturated fat. You can also adjust for common preparations like peeled or seeded guava. Perfect for dietitians, fitness enthusiasts, and anyone using a food diary or calorie tracking app.

How to Use This Tool
Using the Guava Fat Calculator is straightforward. Start by entering the weight of guava you plan to eat — you can type a number directly into the weight field or click one of the preset quick-fill buttons (e.g., 100 g, 150 g, 3.5 oz). Then select the unit (grams or ounces) and the preparation method: whole (with skin), peeled, or seeded. The calculator adjusts the fat content based on the edible portion — peeling removes about 15% of the weight (mostly skin, which contains some fat), and seeding removes about 20% (seeds are higher in fat). Click Calculate to see the breakdown of total fat, saturated fat, monounsaturated fat, and polyunsaturated fat. Use the Reset button to clear all fields and start a new calculation.
Formula Explained
The calculator uses standard USDA nutrient data for raw guava (whole fruit). Per 100 grams of edible portion, guava contains approximately 0.95 g of total fat, of which 0.272 g is saturated, 0.087 g is monounsaturated, and 0.401 g is polyunsaturated. The remaining fat (about 0.19 g) consists of other fatty acids and trace lipids. The formula is simple: Fat = (adjusted weight in grams / 100) × fat per 100g. The adjusted weight accounts for the preparation factor (0.85 for peeled, 0.80 for seeded, 1.0 for whole). For example, if you eat 150 g of whole guava, the total fat is (150 / 100) × 0.95 = 1.425 g.
Note: The fat values are based on the USDA FoodData Central entry for guavas, common, raw. Actual values may vary slightly by variety (e.g., pink vs. white guava) and growing conditions.
Worked Examples
Example 1: You eat 200 g of whole guava. Total fat = (200/100) × 0.95 = 1.90 g. Saturated = 0.544 g, monounsaturated = 0.174 g, polyunsaturated = 0.802 g.
Example 2: You eat 5 oz (141.75 g) of peeled guava. Adjusted weight = 141.75 × 0.85 = 120.49 g. Total fat = (120.49/100) × 0.95 = 1.145 g.
Example 3: You eat 100 g of seeded guava. Adjusted weight = 100 × 0.80 = 80 g. Total fat = (80/100) × 0.95 = 0.76 g.
Tips for Accurate Tracking
- Weigh your guava on a kitchen scale for the most accurate results. Volume-based estimates (e.g., "one cup") can vary significantly.
- If you eat only part of a guava (e.g., half), enter half the weight.
- Remember that guava fat is mostly unsaturated — the polyunsaturated fat includes linoleic acid (omega-6), which is an essential fatty acid.
- For diet planning, combine this calculator with other tools like Guava Calcium Calculator to get a fuller picture of guava's micronutrient profile.
Frequently Asked Questions
Q: Is guava high in fat? No. Guava is a low-fat fruit — 100 g contains less than 1 g of fat. Most of its calories come from carbohydrates (about 14 g per 100 g) and fiber (about 5 g per 100 g).
Q: Does the fat content change when guava is cooked? Cooking can cause some water loss, concentrating nutrients slightly, but the fat content per gram of cooked fruit remains similar. This calculator is designed for raw guava.
Q: Are guava seeds edible? Yes, guava seeds are edible and contain a small amount of fat. The "seeded" option in this calculator removes the seeds, so if you eat the seeds, use the "whole" option instead.
Q: Where can I find more detailed nutrition data? The USDA FoodData Central database provides comprehensive nutrient profiles for thousands of foods. You can access it at fdc.nal.usda.gov.
