Compare the nutrition of an apple and apple juice. When juices are processed from fruit it takes out a lot of the benefits of fruit like fiber and nutrients like potassium. Plus fruit is not as calories dense as juices so for those looking to lose weight fruit juices are not a good choice. Trying to lose weight? Eat your fruits and vegetables, don't drink them.
The sugar in fruit is mostly fructose, it ends in -ose so it is a sugar and your body processes them in a similar manner, not exact since your body processes lactose a little different from the rest (you have glucose, fructose, lactose, and sucrose). In the end they are all sugars and your body treats them as such.
The fear of sugar is overblown? Then why are over 70% of Americans overfat? Notice I didn't say overweight, I said overfat so let's not go down the BMI rabbithole. Look at most processed foods, they are loaded with sugar. Go to some place like Italy and compare the sugar content in their foods like bread to ours, sugar is not the third or fourth ingredient like it is on most wheat and white breads like here.
1 in 3 American adults are prediabetic and over 40% are diabetic or prediabetic. So yeah there is a huge sugar epidemic in the US. Going from the food pyramid to the myplate is a step in the right direction but most people still have no idea how to eat healthy, hence how almost half of the people in the US consume way too much sugar.
Red meat is very nutritious (especially grass fed or wild hunted) as most contain vitamins A, B, C, E, iron, selenium, zinc, etc. as well as essential fatty acids. Plus you have beef, elk, bison, elk, and lots of choices that vary in fat content.
I have always told people to earn their carbs, starting your day off with sugar or a bagel spikes your blood sugar level. A better choice would be eggs with avocado and fresh sourdough if you need some carbs. Eggs are some of the most nutritious foods out there, avocados are loaded with healthy fat, and the fermentation of sourdough has several benefits.
Apple

Apple juice (I used Simply since they claim to be on the healthier side)
