Nutrition literacy100 grams and a real serving are not the same thing.
A 100 g reference makes foods comparable, but it may be much larger than a normal amount of spice or much smaller than a whole piece of fruit. Start with the 100 g value, multiply by the amount actually eaten, and then interpret that number within the whole day.
Energy and macronutrients are useful, but no single number summarizes nutritional quality. Look at fiber, vitamins, minerals, preparation and the overall eating pattern together.
Seasonal contextA seasonal calendar is local, approximate and changeable.
The English calendar on this site explicitly refers to general harvest periods in Turkey. Climate, region, altitude, greenhouse production, storage and imports can all extend or shift availability. Visitors in Europe or North America should use local agricultural calendars for precise local timing.
Data approachWhy a food value is not one universal constant.
Cultivar, maturity, soil, weather, laboratory method, edible portion and cooking can change measured composition. We preserve comparable per-100 g values, disclose approximation, use cautious benefit language and avoid presenting a nutrient number as a treatment claim.
