Overview of Nutrition & Diet Quality
FNH 250 Framework
What is this nutrient?
Why do we need it?
Where do we get it?
What happens if we get too little (i.e. deficiency) or too much of it?
Common examples of nutrients that work together:
Vitamin and calcium – important for bone health
Iron and vitamin C (in women)
• Alkaline diets
• Organic foods more nutritious than conventional
• Low CHO diets vs. low fat diets for weight loss
• Removing red meat
• Vegan diets are healthier
• Paleo diet
• Dairy products impact on bone health
• Juicing and juice cleanses
• Replacement sugars
• Intermittent fasting
– the nutrients found in food and how our body handles
Absorption is to break the food apart to extract the nutrients
They are external to the body until they are absorbed across
the wall of the intestines
What comes out through excretion in urine are nutrients that
have been processed and filtered (after absorption)
– must meet three criteria
Vitamin and calcium important for bone health. Controversy ideas: alkaline diets, organic foods more nutritious than conventional, low cho diets vs. low fat diets for weight loss, removing red meat, vegan diets are healthier, paleo diet, dairy products impact on bone health, replacement sugars. Nutrition the nutrients found in food and how our body handles them. Absorption is to break the food apart to extract the nutrients. They are external to the body until they are absorbed across the wall of the intestines. What comes out through excretion in urine are nutrients that have been processed and filtered (after absorption) Goal: moderate intake what you want to go for in a healthy diet. Classes of nutrients: water most important e. g. kidneys would shut down without water, involved in hydrolysis/condensation reactions, solvent medium like in blood (inorganic) Rda/ai reflects controversies and confident level (solid evidence) Eating well with canada"s food guide moved from food rules to a guide.
