<h3>1. Walnuts Are Technically Seeds, Not Nuts</h3>

Though we call them <b>nuts</b>, walnuts are technically the seeds of the walnut tree. The outer shell protects the seed inside, which we enjoy as a healthy snack. Botanically, true nuts don’t split open to release seeds, but walnuts do, placing them in a category called <b>drupes</b> alongside foods like peaches and cherries.

<h3>2. Ancient Origins of Walnuts</h3>

Walnuts have a rich history, dating back to ancient civilizations. They’re one of the oldest known tree foods, with evidence of cultivation in <b>Persia over 7,000 years</b> ago. The <b>Greeks and Romans</b> prized walnuts as <b>Jupiter’s royal acorn</b>, and they were considered a luxury food in early European cultures.

<h3>3. Walnut Trees Are Diverse</h3>

There are <b>over 20 species</b> of walnut trees globally, but the most common varieties are <b>English walnuts (Juglans regia)</b> and <b>black walnuts (Juglans nigra)</b>. English walnuts are more commonly consumed because of their mild flavor and easier-to-crack shells, while black walnuts have a bolder, earthy taste and are used in certain specialty foods and crafts.

<h3>4. Walnuts Are a Natural Brain Food</h3>

One of the most interesting things about walnuts is that they resemble tiny brains! Interestingly, they’re known to support brain health thanks to high levels of <b>omega-3 fatty acids, antioxidants, and vitamin E</b>. Eating walnuts regularly has been linked to improved cognitive function and reduced oxidative stress.

<h3>5. Environmental Benefits of Walnut Trees</h3>

Walnut trees offer environmental benefits beyond their nutritious seeds. They help <b>reduce soil erosion, contribute to biodiversity</b>, and provide shade, cooling their surroundings.
