The high levels of fat and sodium in junk
food and fast food can contribute to heart
disease by raising blood cholesterol levels
and contributing to arterial plaque build up.
The high levels of trans fatty acids found in
many junk foods and fast foods can lead to
fatty liver deposits, which, over time, can
cause liver dysfunction and disease.
Junk Food Can Lead to Diabetes
Over time, the high levels of sugar and simple
carbohydrates in junk food can lead to type 2
diabetes. This occurs because eating too
much sugar puts your metabolism under
stress; when you eat a lot of refined white
sugar and simple carbohydrates, your body
has to pump up insulin production to prevent
a dangerous spike in blood sugar levels.
Because junk food doesn’t contain the protein
or complex carbohydrates that your body
needs to maintain consistent blood sugar
levels, your blood sugar levels will drop
suddenly soon after eating. You’ll crave sugar
and likely end up eating more junk food.
Over time, this stress damages your body’s
ability to use the insulin secreted by your
pancrease. A healthy diet can help maintain
your body’s insulin sensitivity.
Even in the short term, eating too much junk
food can make you feel really uncomfortable.
It can lead to mood swings and constipation,
and lower your energy levels so that you lack
interest in the exercise you need to burn off
those extra calories.
