Eating for Energy: Supporting your Mitochondria
No matter your lifestyle, boosting your energy and supporting overall well-being comes down to a few simple essentials: staying well-hydrated (especially with electrolytes), nourishing your body with the right foods, and getting enough quality rest.
Mitochondria are like tiny power plants in your cells—they create the energy your body needs to function, as ATP, from the food you eat. But they do more than just make energy. They also help regulate calcium levels, support fat and iron processing, and play a role in cell cleanup and renewal. When mitochondria aren’t working properly, it can affect how your cells produce energy, stay balanced, and function overall. That’s why keeping your mitochondria healthy is so important for your overall health and preventing disease.
Mitochondrial health depends on your genes and your body’s metabolism—both of which can be heavily influenced by what you eat. A balanced dietary lifestyle can defend the body against certain types of diseases, such as obesity, diabetes, Parkinson’s disease, and cardiovascular diseases. Today, we’re learning how to pick the right foods to boost energy and stay energized throughout the day.
Smart Carbs for Steady Energy
You’ve probably heard of the glycemic index (GI)—it’s a scale from 0 to 100 that measures how much a carbohydrate-containing food raises your blood sugar within about two hours after eating. Foods with a low GI (55 or less) cause a slower, smaller rise in blood sugar. Medium GI foods fall between 56–69, while high GI foods (70–100) cause a rapid spike in blood sugar.
Generally, complex carbohydrates—like whole grains, fruits, vegetables, and legumes—have a lower to medium glycemic index (excluding watermelon, pineapple, ripe bananas, and some dried fruits, which have a higher GI). These foods take longer to break down because they have longer molecular chains, which means they provide more steady, long-lasting energy. They’re also rich in fiber, vitamins, minerals, and antioxidants and because they digest more slowly, they cause a steadier rise in blood sugar and support optimal health. This also helps support healthy mitochondrial function by lowering oxidative stress and inflammation, which can otherwise harm the mitochondria number and size.
On the other hand, simple carbohydrates—like processed foods, sugary snacks, baked goods, and refined cereals—are broken down quickly by the body, causing a rapid spike in blood sugar followed by a quick drop, which can leave you feeling drained.
In addition to the glycemic index, there’s the glycemic load (GL), which gives a fuller picture. It considers not just how fast a food raises blood sugar (GI), but also how many digestible carbs it contains (excluding fiber). A GL of 10 or less is low, 11–19 is medium, and 20 or more is high.
Foods with a high glycemic load include things like potatoes, corn, and other starchy vegetables, candy bars and baked goods, white pasta, and refined cereals. Low glycemic load foods include oranges, apples, beans, carrots, peanuts, cashews, and bran cereals.
So next time you’re craving a snack but want to avoid the energy crash, reach for something like apple slices with peanut butter, a handful of mixed nuts, or a refreshing orange.
Protein and Fats for Long-lasting Energy
Fueling with fats
We’ve already explored the differences between saturated and unsaturated fats and how they impact your health. When it comes to supporting your mitochondria, unsaturated fats—especially omega-3s like EPA and DHA—are the most beneficial. You can find these healthy fats in fatty fish like salmon, sardines, and mackerel, as well as in certain nuts and seeds. Don’t forget—ALA, found in plant sources, can also be converted into EPA and DHA in the body.
As fat cells develop, their mitochondria become much more active. When mitochondria don’t work properly in fat cells, it can lead to problems like poor fat burning, imbalanced hormone release, and issues with blood sugar control. In brown fat cells, weaker mitochondria mean less heat production, which has been linked to weight gain, especially from high-fat lifestyles. This fat accumulation in the cells can cause insulin resistance to develop. This happens because cells need a healthy balance between making energy and managing stress from harmful byproducts like reactive oxygen species (ROS). Without that balance, things start to go off track.
Powerful Proteins
As we get older, our mitochondria naturally begin to slow down. This can lead to feeling more tired and noticing a drop in muscle strength. The good news is that with the right nutrition, especially high-quality protein, we can support mitochondrial function and help maintain our energy and muscle health. Protein-rich foods like chicken, fish, eggs, beans, and nuts provide the body with essential amino acids. These amino acids help produce L-carnitine, a compound that plays a key role in turning fat into fuel by transporting it into the mitochondria in the muscles, especially during aerobic exercise. By fueling your body with the right proteins, you’re not only supporting your muscles but also keeping your energy levels strong as you age.
Bringing It All Together: Nourish Your Energy
Supporting your mitochondria is one of the most powerful things you can do for your energy, metabolism, and overall health. By focusing on smart carbs, healthy fats, and high-quality proteins, you’re giving your body the tools it needs to thrive—cell by cell. Remember, small, intentional choices add up. Choosing whole foods that stabilize blood sugar, reduce inflammation, and fuel your mitochondria is a foundational part of living a functional, holistic lifestyle.
