Aside from obesity and cavities, here is why you shouldn&#39;t eat too much chocolate:
<ul>
<li>Chocolate in extremely large amounts can actually poison you. The poison comes from the roasted seeds of the Theobroma cacao plant</li>
<li>The toxic components found in this are: methylxanthine, alkaloids, theobromine and caffeine</li>
<li>The lethal dose to kill a person is = 1,000 mg/kg of the person&#39;s body weight</li>
</ul>
However, theobromine levels vary by chocolate type with cocoa powder and dark chocolate.

Too much chocolate is bad for you

<ul>
<li>Theobromine meddles with the nervous system, respiratory system, and the cardiovascular system. It may also cause excess urination.</li>
<li>With enormous amount it can: increase heart rate, cause extreme sweating, trembling, loss of appetite, severe headache, and a drop in blood pressure.</li>
</ul>

Theobromine and its effects on the body

Chocolate is a good treat for yourself, but not for your dog.
<ul>
<li>Dogs can eat chocolate but only with a very small amount. Chocolate to dogs can be extremely poisonous. A 100g of chocolate can be deadly to a 10-kg dog.</li>
<li>Chocolate is metabolized in a very sluggish manner and could take days to clear from your dog's body.</li>
<li>It is much better to feed them a specifically-made treat for your dogs, and if you're wondering, cats are even more less tolerant of chocolate!</li>
</ul>

Something to keep in mind this Halloween.

Americans buy 90 million pounds of chocolate during the week of Halloween, a marveling statistic widely reported by various news sources. With all that chocolate floating around, it’s intriguing to consider whether eating too much of this confection can kill.

In humans, the main health risks for chocolate overindulgence are <a href="https://www.psychologytoday.com/us/conditions/obesity">obesity </a>and cavities.
