1
“Superfoods”
2
What are they? “special category of foods” “calorie sparse” “nutrient dense” So they pack a lot of punch for their weight!
3
“Superior sources of antioxidants and essential nutrients” As soil quality decreases, and food has less nutrients, we will need to rely more and more on plants with a higher nutrient density! “Tend to be vibrant colors” “pigments = phytochemicals; protect the plant, protect us too”
4
What’s the catch? “No legal definition for superfood” This means that anyone can claim that their product is a superfood in the U.S. “European Union: company must prove benefit to use word on label”
5
“Organics vs. Conventional Crops” Part two of our lesson…
6
What’s the hype? And what’s the difference? And if it’s more expensive, why should we bother? “Organic describes the crop’s method of handling and production.” It doesn’t tell us anything about nutrition…organic bacon!
7
Use of the word on packaging “Organic on a label is regulated by the USDA, unless the company makes $5,000/year or less.” So small, roadside farmers are exempt from these inspections.
8
How can the USDA tell? It’s hard to do! “New test in development looks for higher levels of nitrogen-15 in the soil.” This is found in soil without modern fertilizers.
9
So what does it mean? “Organic means:” “no synthetic fertilizers or pesticides” Remember though, they can get contaminated! “no GMOs” “no feeding animals other animals or manure” You heard that right!
10
“No growth hormones” Growth hormones are given to some animals to make them grow faster and get to market sooner. BGH, for example, Bovine Growth Hormone. Made by….Monsanto!
11
“No food irradiation: exposed to radiation to kill bacteria”
12
What about free-range? Free-range generally means that the animals in question (usually chickens) have been able to run around in a larger area than a pen. However…. “There is no regulation of free-range animals.”
13
“Benefits of Organic Food” “Slightly higher levels of minerals, vitamin C, antioxidant phytonutrients” Some studies find this, some don’t, so we’re not absolutely sure. Why might this be?
14
“Organics no pesticides” “Therefore, plants must evolve natural protections” “Often, antioxidants” Which we get the benefit of when we eat them!
15
Do they taste different? Some say yes. “Chemical fertilizers encourage water uptake” “Less water, less flavor dilution.” So these crops may be more flavorful.
16
Can we measure flavor? Yes! The same way they do in a soda factory… “Brix score is a measure of sugar concentration.” “organics higher Brix scores!”
