🍚 Carbohydrates' Impact on Blood Sugar

The speaker begins by emphasizing the importance of carbohydrates in the diet due to their direct impact on blood sugar levels. They explain that various foods, once digested, are converted into glucose and other sugars that enter the bloodstream. In contrast, foods like meat, certain dairy products, and eggs have minimal carbohydrates. The speaker also highlights that while some dairy products contain carbs, others like cheese and cream have very low or no carbohydrates. The nutritional importance of carbohydrates is underscored by their role in brain function, as the brain is the primary user of glucose. Additionally, carbohydrate-rich foods such as beans, whole grains, fruits, and vegetables are noted for their fiber content, which includes both soluble and insoluble types, and their unique vitamin and mineral profiles. The speaker also touches on the fact that carbohydrates are typically low in saturated fat, which is beneficial for heart health. The discussion then shifts to dietary guidelines, with a reference to the 2015-2020 guidelines set by the Institutes of Medicine, suggesting a carbohydrate intake of 45-65% of total daily calories for a healthy American diet. The speaker provides a nuanced view, suggesting that individuals, especially those with diabetes, might need to adjust this range based on their activity levels and personal tolerance.

📊 Carbohydrate Intake Recommendations

In this section, the speaker delves into the practical aspects of carbohydrate intake, providing a detailed breakdown based on calorie needs. They reference a table that outlines recommended carbohydrate intake for individuals with varying calorie requirements, ranging from 1200 to 3000 calories per day. The speaker also introduces a resource, calorieking.com, which allows individuals to calculate their personalized calorie needs based on factors like height, weight, gender, and exercise level. Additionally, the speaker mentions the dietary reference intake (DRI) for carbohydrates, set at a minimum of 130 grams per day by the Food and Nutrition Board, Institutes of Medicine, and National Academies of Science. This minimum is recommended to meet basic physiological needs, regardless of age, except during pregnancy when it increases to 175 grams. The speaker concludes by offering general guidelines for carbohydrate intake at meals, differentiated by gender, age, and activity levels, suggesting lower intakes for more sedentary individuals and higher intakes for younger, more active individuals.

play00:00

So, I want to talk about carbohydrate foods because they have the main

play00:03

impact on the blood sugar. And so all of these foods shown here

play00:08

are going to be digested and turned into glucose

play00:12

and other individual sugars that enter the bloodstream.

play00:17

Foods that have little or no carbohydrate would be flesh.

play00:20

So, meat, chicken, fish, certain dairy products

play00:23

have carbs. Milk and yogurt have carbs but cheese, cream cheese, and cottage

play00:28

cheese have little to none. Cream and half and half also very low in

play00:32

carbs. Eggs, tofu, seeds, nuts, nut butters, avocados all of

play00:37

the fats, oils, butter, margarine, and then some of

play00:40

the vegetables are so minimal in carbohydrate. Lettuce, for example, I think

play00:44

there's two grams of carbohydrate in a cup of lettuce, one of which is fiber

play00:48

so it leaves you with one gram. I think you burn more than that chewing the

play00:51

lettuce. So I wouldn't count the lettuce, limes, or

play00:54

lemons. So, why are carbohydrates important? So

play00:58

first of all the main user of glucose is your brain. The brain uses more than

play01:03

any other part of your body, except you know, if you're out

play01:06

exercising the muscles are sucking it up as well.

play01:10

But not only that, the foods, the carbohydrate food groups, carry

play01:14

specific nutrients and plant foods like beans, whole grains, fruits, and vegetables

play01:20

are rich in fibers and we'll talk about the benefit of soluble and insoluble

play01:24

fiber later. But each food group has its unique, you

play01:29

know, often are rich in certain vitamins and

play01:32

minerals and they don't always cross over, that

play01:34

that you know not not exactly the same. So a balanced diet is a

play01:38

is a way to get the complement of nutrients that we need.

play01:42

Carbohydrates are also naturally low in saturated fat. And as you know saturated

play01:47

fat is linked to heart disease. So, when you ask you know, "How much of the

play01:53

diet should be carbohydrate?" and this is where

play01:56

there's going to be debate forever into the future, because not everybody's going

play02:00

to agree on this. And so I'll look at a couple of the

play02:03

things that are our standards. So, the 2015 to 2020

play02:09

dietary guidelines are set by the Institutes of Medicine.

play02:13

And in the left column what they're showing is

play02:16

their guideline for the breakdown of carbohydrate, protein, and fat in the diet.

play02:22

This isn't specifically for diabetes, this is the general guidelines for

play02:25

healthy Americans. And they're saying, and it's a wide wide

play02:29

range, 45 to 65 percent of calories should be carbs.

play02:33

Now having done diabetes management for 28 years I'll say

play02:37

60 65 is a lot. And I don't think most people with diabetes are going to

play02:42

tolerate that unless they're riding their bike to Utah this weekend.

play02:45

So you might, you know, you might not want to go on the upper ends.

play02:49

The protein 10 to 35 is what they recommend as,

play02:52

as part of the diet. And the fat 20 to 35 percent.

play02:57

Now the diabetes care journal that I just pointed out

play03:01

has done observational studies and looked at what the average intake is for

play03:07

people with diabetes, and the average intake falls around 45 percent of the

play03:10

calories coming from carbs. Some people higher, some people lower but

play03:14

that's the average. And their protein was noted at 15 to 20

play03:19

percent. And fat at 35 to 40. So most people fall

play03:22

pretty close to what would be generally a, you know, guideline for a healthy

play03:27

balanced diet anyway. In this case the fat content was higher,

play03:31

a little bit higher, but provided that that's healthy fat, you

play03:35

know, heart-healthy monounsaturated, polyunsaturated fats,

play03:38

that doesn't mean that's a bad thing. We're going to talk about the different

play03:42

types of fats in a bit. So, you know I'm throwing numbers out

play03:46

there and then people are, you know, "What does that really mean for

play03:49

me?" And so what I did was I crunched numbers just to give you a table that

play03:53

you could look at and I did calorie intakes from twelve hundred to three

play03:57

thousand. I don't know that anybody in the room

play03:59

needs 3,000 calories but I've done, you know, diabetes management for 18 year

play04:04

old football players who do, and so that's why there's such a big

play04:08

table there. But I made four columns, remember that

play04:11

they said 45 to 65 carbs, I did 45 to 55 and I added 40

play04:18

on my own because plenty of people can get by on less carbs

play04:21

and still have a healthy balanced diet. And a lot of people with diabetes strive

play04:26

to be somewhat on the lighter side of carbs.

play04:29

I'm just suggesting without going too low this might be a way of looking at it.

play04:34

Now also there's a little guide up in the right corner,

play04:39

calorieking.com, and what they have at calorieking.com is

play04:44

a little button that says how many calories should I eat.

play04:46

And you plug in your height, weight, gender, your exercise

play04:50

level and it will crunch those numbers and say, "Hey

play04:54

you probably need about 1800 calories a day."

play04:57

If you want to lose weight, 1300, it gives you the buttons for, "Do you want to lose,

play05:01

or stay the same, or gain weight?" And then you come up with a basic

play05:05

calorie level. And then you could use this table to get an idea of how many

play05:08

carbs that might be. I do want to point out that the Food and

play05:12

Nutrition Board, Institutes of Medicine, National

play05:16

Academies of Science have a minimum recommended amount of carbohydrate.

play05:20

And that's called the dietary reference intake and that number is 130 grams. So

play05:25

that's their studied number of the amount of carbohydrate suggested

play05:30

for the basic, functioning needs. That doesn't include

play05:34

exercise, it doesn't include the fact that some people are six foot tall

play05:39

and have more muscle, so they're still suggesting calculating it based on

play05:43

somebody's personal needs. But they're giving a

play05:46

minimum of 130. And the funny thing is is when

play05:50

you look at the table it says if your age is one to three 130

play05:54

grams. If your age is four to eight 130 grams. All ages were 130 grams until

play06:00

you got to pregnancy, is 175. So that would be where that number comes

play06:05

from. So if you wanted to just bypass all of

play06:09

those tables and all that math you could just say well what sort of a ballpark

play06:13

amount of carbohydrate people might want to aim for and I broke

play06:17

it out into women and men and then I gave three sections. Maybe

play06:21

somebody who wanted to be on a lower carb intake, or somebody who was older,

play06:25

more sedentary. A woman might be 30 to 60 grams at a

play06:29

meal. And a man might be 45 to 75. Then you

play06:33

have younger people who are more fit and more active

play06:36

and, and you know more muscular, and they have lower metabolism, sorry

play06:39

higher metabolisms, and they can burn more calories.

play06:42

And so you can see that there's a variety of of things to choose from here.
