Nutrition is crucial
for health. You can literally make yourself very sick
by eating the wrong foods all the time. I know this first hand
If you don't feel well, mentally, why risk your health and make things worse with bad food or bad eating habits? Improve any way you can, starting with one thing you can
control — what goes into your mouth.
A healthy diet should consist of plenty of vegetables. It should not include a lot of sweets (sugar is empty calories and it hurts your immune system). It should not include lots of fats (it is bad for your heart and circulation).
Vegetables may not sound that tasty by themselves; sometimes you have to prepare them a certain way, with spices and herbs, but once you stop eating junk food you start to notice how good vegetables can be and you feel a lot better for making a good decision, on top of feeling healthy in general.
I know it is hard not to splurge on junk food when you feel bad, but you are actually making things worse. Comfort food will not
solve your problems (the reasons why you are depressed). The comfort or happiness is only temporary,
and you are going to pay for eating the wrong things in the long run. It's just like drugs — they don't fix anything; they just mask your symptoms and introduce new problems. But don't take my
word for it, do some reading yourself.
