Consume Too Much Good Things Can Be Bad

There are some things that you just can't have too much of. It can be damaging if you consume too much. Below are some surprising examples.

Vitamin C is an essential nutrient that needs to be ingested every day because our bodies don't produce or store it. What your body doesn't need is flushed out in your urine, but it's still possible to take too much. Mega-doses of vitamin C can cause gastritis, nausea, diarrhea, and kidney stones, according to the Mayo Clinic. In rare cases it can make you tired and dizzy.

Protein helps build muscle, blood, skin, hair, nails, and more. There is a long list of health benefits associated with eating proper amounts of protein from providing energy to keeping the immune system in good shape. But eating too much protein can cause kidney problems, dehydration, and osteoporosis, and it may be linked to certain cancers.

Soybeans are popular because they boast many health benefits from lowering cholesterol to reducing the risk of certain types of cancer, but that doesn't mean you should eat soy foods with abandon. Some compounds in soybeans mimic the hormone estrogen. Animal studies suggest that large amounts of soy might reduce fertility in women, trigger early puberty, and disrupt development in fetuses and children.

Exercise is something most of us don't get enough of. About 30 minutes of moderate exercise a day is enough to ward off chronic diseases such as diabetes, improve mood, and deliver a whole bunch of health benefits. Shoot for at least 60 minutes a day, 5 to 6 times a week if you want to get the most benefits from exercise. Is there such a thing as too much exercise? Yes, and it can lead to injuries, exhaustion, depression, and long-term health problems.

The same rules apply for things that are traditionally thought of as being bad for you. Moderate amounts of dark chocolate, coffee, and red wine can be good for you, so go ahead and indulge every now and then.
