Workshop 4 Flashcards
Seeds
contain:
- Embryonic plant with food supply
- Outer layer for insulation and protection
3 groups of seeds:
- Grains/cereals
- Legumes = seeds from pod vegetables or beans
- Nuts & oil-rich seeds
Legumes
o Folate, calcium, phosphorus, potassium, iron, magnesium, zinc, thiamine, copper
o Sources of fiber, low fat
o Soybeans : higher in protein and fat, contain phytoestrogens
o Peanuts : highest amount of fat
Nuts & oil-rich seeds
o Higher in fat and calories
o Vitamin E, folic acid
With what should you consume seeds?
Consume them with vitamin C, it will enhance iron absorption
Tea (tannins)
__ reduces iron absorption
Their mineral bioavailability is reduced due to binding __
to fibre or phytates
To reduce phytate activity in foods :
roast nuts, soak beans before cooking, ferment foods, sprout grains & beans
Legumes : lower in__
Other plant foods : lower in __
methionine
lysine
Plant proteins
lower quality than animal proteins, lack a sufficient quantity of aa and the proper ratio of essential aa
Legumes are low in
Methionine, tryptophan
Nuts are low in
Lysine, tryptophan
Grains are low in
Lysine, threonine, tryptophan
Seeds are low in
Lysine, methionine
Limiting aa =
aa present in the least quantity
Is gelatin a high quality protein
NO but all other meat proteins are
Protein complementarity =
= to include the full essential amino acids, consume complementary foods as a varied diet is consumed within the day (not only at the same meal)
Benefits of sprouting beans & seeds
increases their vitamin content (esp Vitamin C)
Popular sprouts are
mung beans, alfafa seeds
Health risk of raw sprouts
seed contamination with Salmonella, E. coli bacteria
Sprouting =
soaking then rinsing beans daily as they sprout to achieve desired length (Rinsing prevents mold growth)
