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

Health

<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&#39;s body.</li>
<li>It is much better to feed them a specifically-made treat for your dogs, and if you&#39;re wondering, cats are even more less tolerant of chocolate!</li>
</ul>
