WHAT COULD WE DO WITH $622 BILLION?

• End world hunger for 21 years ($30 billion a

year)

• Provide universal healthcare for half of the

US population

• Provide 4 years of college tuition for 3

million students


More than half of Hispanic/Latino American

adults are expected to develop type 2

diabetes in their lifetime. (CDC, 2019)

THERAPY 2019

Diabetes Care, 2019



THERAPY 2019

Diabetes Care, 2019

“Research indicates that low-carbohydrate eating

plans may result in improved glycemia and have

the potential to reduce antihyperglycemic

medications for individuals with type 2 diabetes.”

“As research studies on some low-carbohydrate

eating plans generally indicate challenges with

long-term sustainability, it is important to reassess

and individualize meal plan guidance regularly for

those interested in this approach.”

“This meal plan is not recommended at this time for

women who are pregnant or lactating, people

with or at risk for disordered eating, or people who

have renal disease, and it should be used with

caution in patients taking sodium–glucose

cotransporter 2 (SGLT2) inhibitors due to the

potential risk of ketoacidosis.”


ADA STANDARDS OF MEDICAL CARE,

NUTRITION THERAPY 2019

Low-carb eating plans

• Improved glycemia and lipid outcomes for up to 1

year

• Wide range of definitions for a low-carbohydrate

eating plan

• Most people with type 2 diabetes report carb

consumption 44-46% of kcals

“Efforts to modify habitual eating patterns are often

unsuccessful in the long term; people generally go

back to their usual macronutrient distribution.”

MACRONUTRIENT RECOMMENDATIONS

• No ideal percentage of calories from

carbohydrates, protein, & fat for all people

• Management should be individualized

• Portion control

• The “fork” method

• Fluid food

categorizations

• Confidence and in-

tune with body cues

• Family involvement

“Those with expertise make

changes in how they eat to

care for their diabetes, but

also continue to maintain

traditional food ways.”

TAILORED LIFESTYLE RECOMMENDATIONS BY MEXICAN AMERICAN

WOMEN DIAGNOSED WITH TYPE 2 DIABETES: A QUALITATIVE STUDY


Category Strategies

Environmental

Controls

• Make your own burgers and tacos

• Cook more at home

• Go to the grocery store alone

• Avoid aisles in the grocery store that have the

food items on sale that are bad for you

• Remove temptation from your home

• Not making tortillas helps because when you

buy, once the package is gone, they are gone

Category Strategies

Avoid

Overeating/

Stress Eating

• Don’t let yourself get hungry

• Limit in between snacking

• Keep active, walk

• When you feel stressed or want to eat go for a

walk

• Drink more water

• Satisfy the craving from the beginning so that you

don’t keep eating foods you don’t really want

Cooking Tips

• Don’t drink regular coke-try lemonade with

Splenda or water

• Learn how to use the steamer, broiler, and oven

• Stick with natural foods



Category Strategies

Lifestyle

Changes

• You can eat anything you want-even menudo-

just limit the amount

• Get into a routine

• The progress takes time, don’t do everything at

once, just step by step

• Make separate meals or smaller portions of the

foods you love

• Eat whole wheat flour tortillas

• Get away from processed foods

• Tortillas-flour, limit to once a week

• Eat earlier in the evening



Category Strategies

Family

• Put them (kids) first

• (Think) Your family is going to be healthier

• They may not like it at first, just keep trying, think of

what will happen to you

• Set the table and serve the food, no choices

• Put 2% or 1% milk in the whole milk container,

keep the same label, family thinks they are

drinking whole milk

Active Self-

Management

• Ask (health care providers and other staff) what

exactly you should eat to take care of your

diabetes

• See her doctor to make sure she is on the right

medicines

• See your dietitian

• Take medicines religiously
