The Good/ Bad Carbohydrates Debate. By: Olivia Lange (guest author)

Introduction:  In the nutrition class I teach, students were asked to respond to and prepare a convincing argument to counter the statement, Carbohydrates are bad for you.  One of those students, Olivia Lange, has been asked to be a guest author on this blog site.  Her paper on Good Carbs-Bad Carbs is below. 
It’s a common misconception among the public that carbohydrates are bad for you, or will make you gain excess weight. According to WebMD.com, the enemy that many people are referring to are the refined and processed carbohydrates, which can also strip away fiber. Fiber is important to digestive health through feeding the bacteria in the gut, as well as helping one feel fuller by slowing down glucose digestion (Mayo Clinic Staff, 1). This is one element that is often paired with heart-healthy whole grains and other good-for-you carbohydrates.
Further expanding on the “bad carbs”, one should avoid or cut back on refined foods like white bread or foods high in added sugar. These foods tend to be low in fiber, which will make someone feel less full, and often these foods are stripped of nutrients (“Carbohydrates and Sugar”, 1). Taking away the whole grain and refining it to a polished grain will strip the nutrients. Foods to avoid eating too much of include cakes, cookies, white bread, or other foods that are highly processed, high fat, and loaded with added sugar. Essentially, the simpler you eat, the healthier the food will be for you.
Carbs should be 50% of our daily intake of calories! Eating healthy will provide essential vitamins and minerals, such as Folate, other B Vitamins, and Vitamin C. Simple carbs like the monosaccharides and disaccharides will provide easy, fast energy.  The simple carbs can be found in healthy foods such as milk providing lactose, or fruits and vegetables providing fructose. However, many people eat excessive table sugar, or sucrose, which will lead to an unhealthy diet. Also, it's important to note that complex carbohydrates from the starches (which have fiber too) will provide longer lasting energy. The complex carbs include most or all of the grain group as well as some vegetables, like potatoes!

Milk provides lactose for energy as well as protein, calcium and vitamin D



Good advice to give to a confused friend asking you about carbs would be to cut down on processed foods with too much fat and added sugar.
Many people are lacking important nutrients in their diets. This is true for many Americans, as so many rely on refined foods. An old-fashioned saying that I've heard in my family is to "stick to the outside aisles in a grocery store" which can make sense, because you will find areas for produce, meats, dairy, and breads/grains. However, this phrase is flawed because in the bakery, there are many processed sweets, cakes, cookies, and white breads! This shows that whole grains can be overlooked, though they are very beneficial to one's health.  Therefore, cutting out bread won't necessarily help one's health, but swapping to a new type of whole grain bread or other whole grain source like adding oatmeal to one’s day certainly can.
Oatmeal for heart health and lasting energy
For a second point to convince a friend to eat good carbs like whole grains, is that a diet high in fiber can help heart conditions in a positive way. Additionally, the other simple carbohydrate "sugars", like lactose or fructose will provide fast and easy energy for the body. The complex carbohydrates, or linked chains of sugars, like starches and fiber found in grains and some vegetables like potatoes will provide the longer-lasting energy. Both types are needed to function properly and maintain healthy energy and blood glucose levels!
Apples provide fructose for quick energy
Overall, keeping it simple by cutting back on refined foods and adding whole grains to your day, can promote a healthy lifestyle, and fitting in plenty of plant foods will help as well!

How does coffee and tea affect blood sugar?

Who doesn’t love some morning coffee?   Or, on cold days, a nice hot cup of tea.   Does drinking coffee or tea affect one’s blood glucose levels?    Should healthy adults be concerned about coffee or tea and blood glucose levels?   The Mayo Clinic says that for healthy adults, caffeine will probably have no noticeable effects on their blood sugar or blood glucose levels.   Studies have found that up to 400 milligrams of caffeine is safe for most of us.   A cup of coffee has about 120-180 milligrams of caffeine and most adults drink about 2 cups of coffee a day.   FDA says healthy adults can consume up to 400 mg of caffeine a day which equates to about 4-5 cups of coffee a day, or 10 cans of soda , or 2 “energy shot” drinks.   (See:   Caffeine – good or bad for your health? )     Can drinking coffee or tea reduce chances of getting type 2 diabetes? Some studies have found that coffee, tea, and other drinks with caffei...

Are there drinks that will help lower your blood pressure?

Image
According to the University of Southern California , almost half of Americans over the age of 20 have high blood pressure.   This means an astounding 122 million Americans.   Unfortunately, as you get older it is more likely to have blood pressure increase.   Many people don’t even know they have high blood pressure or hypertension.   The American Heart Association notes at first there are “no obvious symptoms to indicate something is wrong, but HBP can lead to heart attack, stroke, and kidney failure.”    A relative was asking what they could do diet wise to help lower their blood pressure.   We had already discussed the DASH diet (Dietary Approaches to Stop Hypertension).   (See:   Best Diets for Healthy Eating in 2024 .) and physical activity.    Diet wise, they were cutting back on sodium and increasing potassium foods but were wondering if there were anything else like any drinks that could help lower blood pressure?  ...

How to eat for better sleep

Having trouble sleeping?   Are there foods you can eat that would help you sleep?   My husband sent me an interesting article, 8 Eating Habits That Actually Improve Your Sleep . According to CDC , “about 1 in 3 adults in the United States reported not getting enough rest or sleep every day.”   A lot of Americans have problems sleeping, about 50-70 million Americans.   You probably heard that drinking warm milk before bed helps one sleep?   Is this true?   What eating habits really do help you get to sleep and stay asleep? Sleep and hunger Did you know that getting a good night’s sleep affects hunger hormones in your body?   A good night’s sleep can lead to less snacking the next day as it keeps hunger at bay.   A professor of nutrition at Columbia University, Marie-Pierre St-Onge, says, “If you eat better, you sleep better and be more refreshed.   And that helps you make better decision for your diet.”      Some tips to ea...
