Are unhealthy foods really that unhealthy?

VS

It's ok to eat foods that are not great for health and wellbeing, but just not
too often. 

Foods like Biscuits, Fast foods and Sweets are ok to eat in moderation.
These foods are deemed unhealthy but it's ok to have a little treat once
in a while to satisfy your cravings.

The foods referred to as unhealthy foods are often deep fried, full of sugar,
salt, fats and carbs meaning they contain high amounts of fats, oils,
sodium and sugar and when not eaten in moderation become unhealthy.
These foods don't often contain the vitamins and minerals you need for
your bodies to function properly throughout the day. Unhealthy foods can
cause obesity, malnutrition, heart disease, depression,cancer and early
death. They can affect your physical and mental health. 

In today's busy world, people often eat quickly and in a hurry. However,
your brain needs time to process signals of fullness. It may take up to
20 minutes for your brain to realize that you're full. When you eat fast,
it's much easier to eat a lot more food than your body really needs.
