“The human body thrives on a balanced diet of healthy carbohydrates for optimal performance and well-being.”
What Are Carbohydrates?
Carbohydrates are essential organic compounds of carbon, hydrogen, and oxygen atoms. They include familiar forms such as sugars, starches, and fiber. As the body’s primary energy source, carbohydrates provide the energy needed for daily activities and fuel the brain and muscles. Each gram provides about four calories. Choosing the right types of carbohydrates is vital to nourish your body and support your well-being. Remember, caring for your nutritional needs is a compassionate way to care for yourself.
Dietary carbohydrates are classified into two main types based on their chemical structure and digestion rate:
Simple carbohydrates
Also known as simple sugars, simple carbohydrates include monosaccharides (single sugar units), such as glucose, fructose, and galactose, as well as disaccharides (double sugar units), including sucrose, lactose, and maltose. Because they are simple, simple carbohydrates are quickly broken down into glucose, which is then absorbed into the bloodstream, leading to a rapid increase in blood sugar levels.
- Naturally occurring sugars: These are found naturally in foods like fruits, vegetables, and dairy products like Milk and yogurt (plain, unsweetened). Honey and Maple Syrup are natural sweeteners.
- Added sugars: Processed and refined sugars added to foods and drinks, such as candy, table sugar, syrups, and soft drinks.
Complex carbohydrates
Complex carbohydrates are made up of long chains of simple sugars (monosaccharides), forming either oligosaccharides (3-10 sugars) or polysaccharides (more than 10 sugars). Due to their larger molecular structure, complex carbohydrates must be digested into simpler forms, primarily glucose, before the body can effectively absorb and use them for energy. This breakdown means they provide energy more slowly than simple carbohydrates but faster than proteins or fats.
Starches are a type of complex carbohydrate that contains many glucose molecules. Plants produce these polysaccharides.
Fiber is a type of non-digestible complex carbohydrate. It doesn’t provide energy directly, but it does feed the friendly bacteria in the digestive system. These bacteria can utilize the fiber to produce fatty acids that some of our cells can use as an energy source. Additionally, consuming fiber is essential for your overall health, as it promotes healthy digestion, regulates blood sugar levels, lowers cholesterol, and keeps you feeling full for longer. Plant-based foods, including fruits, vegetables, and whole-grain products, contain fiber.
Whole foods, in their most natural state or as close to it as possible, offer numerous benefits that can truly nourish our bodies. They are packed with essential nutrients and fiber, which can positively impact our overall health. By choosing these foods, we can take meaningful steps towards feeling our best and supporting our well-being.
Whole Grains: Brown rice, Quinoa, Oats (steel-cut ), Barley, Bulgur, Farro, Whole wheat (pasta, bread, couscous), Buckwheat. Legumes: Lentils, Chickpeas, Black beans, Kidney beans, Pinto beans, Navy beans, Edamame. Starchy Vegetables: Sweet potatoes, Potatoes, Butternut squash, Pumpkin, Peas. Root Vegetables: Parsnips, Turnips.
Healthy Aging Study
Recent research published in the JAMA Network in May 2025 highlights that the quality of carbohydrates consumed during midlife can significantly influence healthy aging. The study discovered that including fiber and “high-quality” carbohydrates in one’s diet can increase the likelihood of healthy aging by 37%. The researchers defined “high-quality” carbohydrates as whole grains, fruits, vegetables, and legumes.
The Dark Side of Carbohydrates
The BMJ (British Medical Journal) is a peer-reviewed medical journal published weekly by the British Medical Association. Founded in 1840, it’s among the world’s oldest and most respected medical journals. The journal covers research, clinical reviews, news, and commentary on health and medicine.
A study published in The BMJ in February 2024 conducted an umbrella review of epidemiological meta-analyses to assess the links between ultra-processed food (UPF) consumption and adverse health outcomes.
Titled “Ultra-processed Food Exposure and Adverse Health Outcomes,” the study evaluates the quality of evidence connecting UPFs to health risks.
What Are Ultra-Processed Foods?
According to the NOVA food classification system, ultra-processed foods are industrially formulated products that contain multiple ingredients, often including additives such as emulsifiers, preservatives, thickeners, artificial flavors, and artificial ingredients.
They’re often ready-to-eat, heavily marketed, and designed to be hyper-palatable. It’s essential to distinguish between hyperpalatable foods (such as fresh fruits) and naturally pleasant foods, and between high-energy-density foods. While some naturally pleasant foods can also activate the reward system, hyperpalatable foods are specifically engineered to be highly rewarding. UPFs tend to contain excessive amounts of added sugars, sodium, or unhealthy fats. Unless artificially fortified, they often lack the nutritional value of whole or minimally processed foods, such as fiber, vitamins, and minerals.
Here are the key findings and their significance regarding ultra-processed foods.
Researchers led by Melissa M. Lane analyzed 45 unique pooled studies, which included data from nearly 10 million participants (n = 9,888,373).
Health Risks Associated with Ultra-Processed Foods (UPFs):
The study found strong evidence linking higher consumption of ultra-processed foods to an increased risk of over 30 health issues. This includes a 50% increase in the risk of mortality related to cardiovascular disease, a 30-60% increase in the risk of developing type 2 diabetes, and a 40-66% higher risk of obesity.
Evidence suggests links between mental health issues like depression, anxiety, and other conditions, such as heart disease and premature death.
Why This Matters?
This study highlights a growing concern among many about the role of ultra-processed foods in our diets. These foods have been linked to serious health challenges like heart disease, diabetes, and obesity, which can be overwhelming for individuals and families. We must come together to support one another in making healthier choices and advocate for changes that promote well-being for everyone.
We can make a difference together!
Read Labels Carefully. To effectively identify ultra-processed foods (UPFs), look for additives and be aware of high sugar and sodium content. Utilize apps like Yuka or Open Food Facts to confidently scan products and determine their nutritional information and processing levels.
Check the Ingredient List: Ultra-processed foods (UPFs) often have lengthy ingredient lists—typically 5 or more—often including substances not commonly found in home kitchens.
Additives to look for include artificial flavors, colors (e.g., Red 40, Yellow 5), preservatives (e.g., sodium benzoate), emulsifiers (e.g., lecithin, mono- and diglycerides), and stabilizers (e.g., carrageenan).
Sweeteners: High-fructose corn syrup, corn syrup, invert sugar, or artificial sweeteners (e.g., aspartame, sucralose) are common.
Processed Oils: Hydrogenated or interesterified oils (e.g., partially hydrogenated soybean oil) indicate heavy processing.
Prioritize Whole Foods: For optimal health and nutrition, select minimally processed foods, including fresh fruits, vegetables, whole grains, and lean proteins.
Cook at Home: Preparing your meals is a great way to choose fresh ingredients and eliminate unwanted additives. It’s a fun and rewarding way to take care of yourself!
The Bigger Picture:
Many U.S. households turn to these foods because they are affordable, convenient, and heavily marketed. In a fast-paced world, people often rely on what is most easily accessible. Unfortunately, research indicates that ultra-processed foods account for approximately 60% of the average American diet, leading to increased calorie intake. It’s essential to recognize the challenges many people face in making healthier choices.
Based on consumption patterns and available data, here’s a list of commonly consumed ultra-processed foods in the U.S.:
Sodas and Sweetened Beverages, Packaged Snacks, Breakfast Cereals, Frozen and Ready-to-Eat Meals, Fast Food, Packaged Breads and Baked Goods, Candy and Confectionery, Processed Meats, Instant Noodles and Soups, Ice Cream and Frozen Desserts, Sweetened Yogurts and Dairy Drinks, Boxed Macaroni and Cheese, Flavored Coffee Drinks, Margarine and Spreads.
Glycemic Index (GI)
The glycemic index (GI) measures Carbohydrates on a scale from 0 to 100, based on how they affect blood sugar levels. Foods with a high GI (greater than 70) are digested rapidly, leading to a rapid spike in blood sugar and insulin levels. In contrast, foods with a low GI (less than 55) are digested more slowly, resulting in a gradual increase in blood sugar and insulin levels.
High-glycemic foods are often highly processed, such as beverages with added sugar, bakery items, and candy.

Final Thoughts
A balanced diet focusing on high-quality carbohydrates from whole foods—such as fruits, vegetables, legumes, and whole grains—is essential for optimal health. These nutrient-dense options provide a steady energy source, help maintain hormonal balance, and support healthy aging. For example, a 2025 study published in the JAMA Network found that incorporating fiber-rich, high-quality carbohydrates can increase the likelihood of healthy aging by 37%.
On the other hand, it’s essential to be mindful of ultra-processed foods, which are often high in added sugars and refined grains. Items like sodas, packaged snacks, and white bread can disrupt hormones such as insulin, leptin, and ghrelin, potentially leading to increased fat storage and a significantly higher risk of obesity by 40-66%, as highlighted in a 2024 BMJ review.
We can nourish our bodies by prioritizing whole foods, carefully reading labels to avoid unnecessary additives, and cooking at home. This approach helps stabilize hormones and reduces the risk of obesity and chronic diseases. Making thoughtful choices about carbohydrates is a decisive step towards enhancing our long-term well-being and overall health.
