Here are a few options for a WordPress post_tag description for “澱粉” (diànfěn, meaning “starch” in Traditional Chinese), depending on the desired level of detail and context:

**Option 1: Concise and Direct**

* **Description:** 澱粉類食物，包括米飯、麵包等，提供人體能量的主要來源。 (Diànfěn lèi shíwù, bāokuò mǐfàn, miànbāo děng, tígōng réntǐ néngliàng de zhǔyào láiyuán. – Starchy foods, including rice, bread, etc., are the primary source of energy for the human body.)
* **Focus:** Clear and factual, ideal for general use.

**Option 2: Focusing on Food & Cooking**

* **Description:** 烹飪中常用的增稠劑和成分，例如用於勾芡、製作糕點等。 (Pēngrèn zhōng chángyòng de zēngchóu jì hé chéngfèn, lìrú yòngyú gōuqiàn, zhìzuò gāodiǎn děng. – Commonly used thickening agents and ingredients in cooking, such as for thickening sauces, making pastries, etc.)
* **Focus:** Highlights the culinary uses of starch.

**Option 3: Highlighting Natural Context**

* **Description:** 從植物中提取的碳水化合物，如玉米、馬鈴薯、木薯等，是許多常見食物的關鍵成分。 (Cóng zhíwù zhōng tíqǔ de tànshuǐhuàhéwù, rú yùmǐ, mǎlíngshǔ, mùshǔ děng, shì xǔduō chángjiàn shíwù de guānjiàn chéngfèn. – Carbohydrates extracted from plants, such as corn, potatoes, and cassava, are key ingredients in many common foods.)

**Option 4: Medical/Health Context**

* **Description:** 了解澱粉對血糖的影響，以及如何選擇合適的澱粉來源以支持健康飲食。 (Liǎojiě diànfěn duì xuě táng de yǐngxiǎng, yǐjí rúhé xuǎnzé héshì de diànfěn láiyuán yǐ zhīchí jiànkāng yǐnshí. – Understanding the impact of starch on blood sugar, and how to choose appropriate starch sources to support a healthy diet.)
* **Focus:** Relevant for content related to diet, diabetes, or health.

**How to Choose:**

* **Consider your WordPress post content.** Which option best reflects the topics you’ll be tagging?
* **Keep it concise.** You don’t need an entire essay; a clear summary is best for a tag.
* **Use the right tone.** Is your blog more scientific, culinary, or health-focused?

**Recommendation:**

I recommend **Option 1 or 2** for general use. They are both concise and relevant. Choose the one that aligns best with your target audience. If your main content involves recipes and food, then Option 2 is a great choice. If you are describing a range of health and science topics, then option 1 is more suited.
