Artificial sweeteners do not help people lose weight and they
might even do harm
Long term consumption is associated with increased BMO
and elevated risk of cardiometabolic disease
○
-
Alcohol is a CNS depressant, caffeine is a stimulant
When they are consumed together you don't feel as
drunk as you normally would
○
-
Guarana is a complex plant, it could provide additional
stimulation over caffeine alone
-
Red bull has caffeine in it, in Canada it is illegal to add caffeine
to an alcoholic beverage
But they were able to put guarana in it which is a loop
hole
○
People use red bull with alcohol and this has a synergetic
effect
○
-
Anything that provides calories could be labelled an energy
drink
-
Torine is a chemical found in flesh
-
When you culture hair follicles in a petri dish you could get them

Inflammatory foods
Inflammation is a way that the body tries ward off foreign
attackers
Virus, bacteria, splinter
§
○
Messengers like histamine are released and white blood
cells ooze out to protect invaders
○
Inflammation: is a localized protected response elicited by
injury or distruction of tissues which serves to destroy,
dilute or wall off both the injurious agent and the injury
Any time there is an -itis, is an inflammatory
condition
§
○
Redness, pain, swelling, heat, loss of function
○
-
Acute inflammation: when you injure yourself and it heals
-
Chronic inflammation: some sort of toxin and this destablizes
cholesterol deposits and could provoke a heart attack
Anti-inflammatory drugs - statins, celebrex, aspirin, fish
oils
○
Need markers to detect it (c-reative protein is produced in
the liver)
○
-
Foods fight inflammation
Tomatoes, fruits, nuts, olive oil, leafy greens, fatty fish
○
-
Mediterranean diet has been shown to reduce inflammatory
markers such as CRP and IL-6
People are on this are obese or have metabolic syndrome
○
-
Vegetarian diets have also been shown to reduce inflammation
-
Metabolic syndrome is a combination of these risk factors:
visceral obesity, insulin resistance, hypertension, high
triglycerides, low HDL-cholesterol (good cholesterol)
Increased risk of heart attack, stroke, diabetes
○
-
Beneficial: high consumption of vegetables, fruits and nuts,
legumes, unprocessed cereals, fish, high ratio of
monounsaturated fatty acids to saturated fatty acids
-
Detrimental: meat and meat products including poultry with the
exception of cheeses preservable for a long period of time
