L-Phenylalanine is first converted to L-Tyrosine, which is then converted to L-DOPA, which is then converted to Dopamine.
However, it's very misleading to reduce the body to basic formulas like this because these pathways from dietary amino acids to neurotransmitters are all regulated within the body at many different stages, so adding a little extra Phenylalanine to a meal isn't going to give you a dopamine boost. You consume a lot of Tyrosine in a standard protein like chicken breast (multiple grams, potentially) and nobody is getting high off of standard protein. The body is very good at regulating these things.
Right, but "large amounts" of sugar. 250ml of juice (and yes, I know the suggest serving size of orange juice is much less than that, but it's very easy to drink a normal glass of it) is quite a few oranges.
Sugar is, like everything except plutonium, fine in moderation. But "in moderation" is not how sugar occurs in many modern diets.
Unsure if that's because they don't want to write 25g of sugar on the "traffic light" label (it's about 1g per 10ml), or they want people to think the packs are bigger in terms of servings.
If eat a whole orange, the fiber in the orange slows down sugar uptake whereas if I drink juice the sugar hits bloodstream much faster.
