Q

What’s the mechanism of carbohydrate-insulin model to weight gain & diabetes

A

Taking a diet high in digestible carbohydrates increases an insulin-to-glucagon ratio, thus favoring energy storage in adipose tissue. So more of wt u eat (calories) will be stored, leaving fewer calories available for metabolically active tissues.

Q

What’s the treatment strategy for obesity?

A

Lowering insulin secretion through dietary changes may
enhance long-term weight management and chronic disease prevention.
(Take meals tht will not result to major increase in insulin-glucagon ratio)

Q

T/F: Raw veggies are more nutritious than cooked
ones

A

False

-Cooking vegetables increases availability of nutrients

TO DO: incorporate a combination of raw and cooked vegetables into
your weekly menu.

26
Q

T/F: Fresh produce is healthier than frozen

A

False

-Some fruits n vegetables see an increase in sugar content, and nutrient
content deteriorates as they ripen.

Thus; fruits and vegetables are frozen quickly after
harvest, which prevents over-ripening and actively preserves nutrients

Q

A gluten-free diet is healthier

A

False

28
Q

A

True

29
Q

Eggs
