Apparently, a breakfast packed with bacon and toast makes for the perfect hangover cure. In an article by the Telegraph, Erin Roberts of Newcastle University explained:
Food doesn't soak up the alcohol but it does increase your metabolism helping you deal with the after-effects of over indulgence. So food will often help you feel better.
Bread is high in carbohydrates and bacon is full of protein, which breaks down into amino acids. Your body needs these amino acids, so eating them will make you feel good.
Basically the gist of it is that bacon and bread replenish your body with nutrients the excess booze took away the night before. After bingeing on alcohol, your brain is depleted of neurotransmitters -- chemicals that carry messages between cells in the body. Bacon contains a high level of amino acids, which helps boost these levels back to normal and presume optimal brain functioning. Bread comes into play by giving you carbs that get converted to glucose, re-energizing brain cells that have been starved of this key nutrient.
Of course, this should all be taken with a grain of salt since the research is more than 6 years old (2009) and new technology can probably provide a better explanation for this so called bacon-buzzword cure.
Also, just eating in general (especially meats and bread) helps speed up your metabolism, which helps your body get rid of the booze faster.
Also note, not everything you read on the internet is true.
Although, all you really wanted to hear was BACON = HANGOVER CURE. So, you're welcome.
