How do carbohydrates impact your health? – Richard J. Wood


Which of these has
the least carbohydrates? This roll of bread? This bowl of rice? Or this can of soda? It’s a trick question. Although they may differ in fats,
vitamins, and other nutritional content, when it comes to carbs,
they’re pretty much the same. So what exactly does that mean
for your diet? First of all, carbohydrate is
the nutritional category for sugars and molecules that your body breaks down
to make sugars. Carbohydrates can be simple or complex
depending on their structure. This is a simple sugar,
or monosaccharide. Glucose, fructose,
and galactose are all simple sugars. Link two of them together,
and you’ve got a disaccharide, lactose, maltose, or sucrose. Complex carbohydrates,
on the other hand, have three or more simple sugars
strung together. Complex carbohydrates with three
to ten linked sugars are oligosaccharides. Those with more than ten
are polysaccharides. During digestion, your body breaks down those
complex carbohydrates into their monosaccharide building blocks, which your cells can use for energy. So when you eat
any carbohydrate-rich food, the sugar level in your blood,
normally about a teaspoon, goes up. But your digestive tract doesn’t respond
to all carbohydrates the same. Consider starch and fiber, both polysaccharides, both derived from plants, both composed of hundreds to thousands
of monosaccharides joined together, but they’re joined together differently, and that changes the effect
they have on your body. In starches, which plants mostly store
for energy in roots and seeds, glucose molecules are joined together
by alpha linkages, most of which can be easily cleaved
by enzymes in your digestive tract. But in fiber, the bonds between
monosaccharide molecules are beta bonds, which your body can’t break down. Fiber can also trap some starches,
preventing them from being cleaved, resulting in something called
resistant starch. So foods high in starch,
like crackers and white bread, are digested easily, quickly releasing a whole bunch of glucose
into your blood, exactly what would happen if you drank
something high in glucose, like soda. These foods have a high glycemic index, the amount that a particular food
raises the sugar level in your blood. Soda and white bread have a similar
glycemic index because they have a similar effect
on your blood sugar. But when you eat foods high in fiber,
like vegetables, fruits, and whole grains, those indigestible beta bonds slow
the release of glucose into the blood. Those foods have a lower glycemic index, and foods like eggs, cheese, and meats
have the lowest glycemic index. When sugar moves from the digestive tract
to the blood stream, your body kicks into action to transfer it
into your tissues where it can be processed
and used for energy. Insulin, a hormone
synthesized in the pancreas, is one of the body’s main tools
for sugar management. When you eat and your blood sugar rises, insulin is secreted into the blood. It prompts your muscle and fat cells
to let glucose in and jump starts the conversion
of sugar to energy. The degree to which a unit
of insulin lowers the blood sugar helps us understand something called
insulin sensitivity. The more a given unit of insulin
lowers blood sugar, the more sensitive you are to insulin. If insulin sensitivity goes down,
that’s known as insulin resistance. The pancreas still sends out insulin, but cells, especially muscle cells,
are less and less responsive to it, so blood sugar fails to decrease, and blood insulin continues to rise. Chronically consuming
a lot of carbohydrates may lead to insulin resistance, and many scientists believe
that insulin resistance leads to a serious condition
called metabolic syndrome. That involves a constellation of symptoms, including high blood sugar, increased waist circumference, and high blood pressure. It increases the risk
of developing conditions, like cardiovascular disease and type II diabetes. And its prevalence is rapidly increasing
all over the world. As much as 32% of the population
in the U.S. has metabolic syndrome. So let’s get back to your diet. Whether your food tastes sweet or not,
sugar is sugar, and too many carbs can be a problem. So maybe you’ll want to take a pass on that pasta sushi roll pita burrito
donut burger sandwich.

  1. Yeah no a donut and vegan sushi are not the same. Did they also forget about whole grain bread. Don’t compare pasta to donuts. They’re not the same. You should be worrying about all that meat and cheese you’re eating.

  2. This is one of the most misleading “nutrition” videos I’ve ever seen. “Sugar is sugar” is grossly oversimplified. Eat fruit, as much as you want. The more fruit the better. It will not give you diabetes.

  3. Everything is bad for you I stop eating sugar and bread and I’m scared of eating fruits now and I think milk is bad too cause we don’t know what they give the cows all chemicals and anti Bactria make you body become resistance to antibiotics I think we all need to turn into robots 🤖 in this dangerous artificial food chain

  4. Reducing Carbohydrates, increasing Exercise. Boom 50pounds gone just like that. Whoever says that this video is a lie, well my friend you need to pull your head out and educate yourself.

    Stay Healthy guys 👍🏻

  5. I'm watching this while eating white bread sandwich. I finished it before the video said "leads to a serious condition".
    Nahhh~ I'm healthy😂

  6. Philippines eat rice almost 3 times a day. Im Filipino and i eat rice once a day now and i have no heart or diiebites issue. Thank God

  7. Just because you didn't understand all they explain at once, doesn't mean they are wrong. We should be a little bit more humble and try to avoid criticism without a second thought. As unfortunate as it might seem, life is not what we want it to be, don't be resistant and stay open to new ideas (I am not saying you must believe whatever a scientist says just because he/she's a scientist, but PLEASE!)

  8. This has been the truth for me and everyone I know who has battled with weight gain. Limit carb intake and increase exercise makes excess weight melt away.

  9. Sugar and bread may kill more than cigarettes. linked to the metabolic syndrome are the 3 big killers : cardiovascular diseases, cancers, Neuro-degenerative diseases.

  10. Fructose is the cause of metabolic syndrome, a quote by Dr Richard Johnson in his youtube video

    "The Origins of Obesity and the Fattening of Man."
    Dr Johnson, a renal specialist at the University of Colorado says that there are well controlled clinical studies of both animals and humans that prove it, and he actually goes over the findings of those studies. Dr Johnson also says that he looks forward to anybody who tries to disagree with him.
    However, you are never going to hear anything from the government, medical associations or mainstream media about it. They are not willing to change the current paradigm of appeasing the food manufacturers who purposely add fructose to foods to increase sales.
    Fructose causes metabolic syndrome, bottom line.
    It's true.
    It's been proven.

    Watch Dr Johnson's video and then tell me I'm wrong.

  11. Carbs are not required for human survival.. They just give us fuel for energy which can be also acquired from protien and fats, Although In todays age and lifestyle it is hard to maintain a "carbless diet", just eating the optimal amount of carbs(complex carbs) according to the daily energy expenditure is the key to safely consume them..

  12. As an Asian Naga Tribal, I've been consuming two to three plates of rice everyday all my life. It is our daily meal. We just keep changing the curry to go with the rice. We eat lots of red meat, cereals, pulses, veggies and fermented delicacies like bambooshoot, fermented soyabeans, dried fish, smoked meat, shredded beef pickles and most households take fresh milk on a regular basis.

    According to this video, we are consuming a lot of the stuff that is sugar rich. So, Did we somehow evolve/adapt to such eating habits over the centuries? Or are we headed towards an outbreak of sugar related health issues?

    Somebody please suggest if I/we need to break away from this food habits and the alternative solution to this. Thank you.

  13. Google Asian diabetes rates by year. Or heart disease.
    You can see how meat and dairy make people sick.
    Even teen and 20s 30s diabetes and gout rates are increasing.

  14. Meanwhile Italy monches down on pasta like no other country and doesn't care in the slightest about all these technicalities lmfao

  15. I mean I don’t agree to associate natural carbs with processed carbs. I believe if you’re not up and moving no you should not consume a lot of carbs however if you are active you should be able to use NATURAL carbs in your diet

  16. Carbohydrates ARE NOT THE PROBLEM and will NOT cause type 2 diabetes! These videos are the reason why so many people are confused…

  17. Excess sugar is the Main reason for all health problems..If you Consume the things which are white e.g sugar, salt in minimal amount you will be Healthy..

  18. There's no way I could ever believe that eating a moderate amount of non-refined carbs is bad. Why does our saliva contain amylase then? It clearly shows that consumption of carbs was crucial to our ancestors' survival, so much so that those who couldn't break them down in their saliva didn't survive to this day

  19. Rice is carbs and compose of sugar. Thank You for making this informative Videos on YouTube. You can learn more from visual Explanations rather than sitting in a lecture. YouTube is a Good Source of informations, A media platform which is accurate and Truthful. YouTube is a perfect place for Learning and Entertainment. Facebook is a Useful in Communication and Connecting to more People. Both are Useful in everyday Lives.

  20. Voice quality is not good, Voice over sharpness is very high and no base in Voice…I m not able to listen and understand because this video is very important to me

  21. no they are not the same. There is a big different between simple carbohydrates like sugars and complex carbohydrates like starch.

  22. "pasta, sushi roll, pita, burrito, donut, burger, sandwich" haha, how come that actually sound so good? Darn it, I'm actually really trying to stay away from those!

  23. If you do keto you'll be surprised how much better you feel. Of course you have to get over the "keto flu". Plus getting back down to a healthy weight. I've lost 62 lbs in a couple of months. It's not for everyone though. You gotta have some willpower as with any dietary change.

  24. So the problem is not sugar, if we can replace the alpha molecules with beta in between the monosaccharides I bet the struggle will not be as difficult…..

  25. Sugar will never be healthy, high insulin levels will never be healthy… sorry high carb people you are unhealthy, go keto or paleo like normal people <3

  26. I can see how increasing the amount of vocal fry makes the VO somewhat more intimate in its delivery, but honestly it's hard to concentrate on the message.

  27. It's a challenge for me not only because of my love for sweets, but also because my family insists on eating a lot of white bread, and sugary snacks, but also refuse to take the effort of searching for whole wheat bread and not buy the snacks so frequently…

  28. I've been Lifting for 4 years and I made huge progress 455 on squat 500 in the deadlift 315 on the bench but I bought a year ago all those numbers went down as I wanted to get more fit and more lean and I never used to track my calories or my carbs and protein and about a week ago I started tracking my carbs in my protein and all my lives are going up exponentially

  29. Did you know you can slow down the release of sugar in your blood by simply eating a few fruits or veggies before drinking that bottle of coke or any refined food.

  30. there as a video that says, there are essential protein, essential fats but no essential carbohydrates, that should tell us something about carbs.

  31. Directly from the video he said things like vegetables and whole grains contain complex carbohydrates that are linked together with beta bonds, which we cannot break down. Eat all the whole grains and veggies you want. I lost 60lbs after switching from junk food to whole grains, veggies, lean meat, and dairy. And I dropped my blood pressure back to normal levels after being in the prehypertension risk level.

  32. Total Carbohydrate 19 g
    Dietary fiber 4 g
    Sugar 14 g
    could someone please simple explain this the difference between that Dietary Fiber and Sugar and Tatal Carbohydrate on any item Nutritious chart ?
    and the impact as well .
