Plantain Chips: Keto-Friendly Or Not?

Plantain chips are marketed as a healthy alternative to regular potato chips, but are they allowed on a keto diet? The keto diet is a low-carb, high-fat diet that aims to trigger a metabolic state called ketosis, where the body burns fat for fuel instead of sugar. To maintain ketosis, one must consume no more than 20 to 50 grams of net carbs per day. So, are plantain chips keto-friendly, or will they knock you out of ketosis?

Plantain chips are not keto-friendly

Plantains are high in carbohydrates, with a medium-sized ripe plantain containing around 40 grams of net carbs, and green plantains containing between 15 and 20 grams of carbs. A ketogenic diet is a low-carb, high-fat diet that primes your metabolism to burn fat for fuel instead of sugar. To trigger and maintain ketosis, it is recommended to consume no more than 20 to 50 grams of net carbs per day. Eating just one plantain will knock you out of ketosis.

Plantains are also high in starch, which is converted into sugar as the plantain ripens. This means that ripe plantains have a higher glycemic index, which can cause spikes in blood sugar and insulin levels, interfering with ketosis.

When plantains are cooked, such as when they are made into plantain chips, the heat destroys the resistant starch, increasing the glycemic index even further. Additionally, manufacturers of plantain chips often add vegetable oils and sugar to increase shelf life and enhance flavor, which can further impact blood glucose and insulin levels.

Therefore, if you are following a ketogenic diet, it is best to avoid plantain chips and opt for other keto-friendly snack options.

Green plantains are lower on the glycemic index

Green plantains are considerably lower on the glycemic index (GI) than yellow bananas. GI is a scale of how quickly a food raises blood sugar levels compared to glucose, which has a GI of 100. Foods with a high GI spike blood sugar and insulin levels quickly, which interferes with ketosis and pushes your body to run on sugar, which can lead to weight gain and may cause long-term metabolic health issues.

Green plantains have a GI of 40 and between 15 to 20 net carbs, making small amounts safe on keto. In contrast, ripe plantains contain lower amounts of starches and more sugars, with a GI of around 60. As plantains ripen, their starches are converted into sugars, which is why ripe plantains are sweeter than green ones.

Green plantains are rich in resistant starch, an indigestible type of carbohydrate that supports gut health and blood sugar control. Resistant starch is not broken down and absorbed in the small intestines. Instead, it passes into the colon relatively intact, where it serves as a fuel source for the friendly bacteria in the gut. Because resistant starch is not absorbed, it doesn't impact blood sugar levels and keeps insulin low. It also slows down digestion, which significantly buffers the impact of carbs on blood sugar and insulin levels, helping with weight loss and lowering the risk of insulin resistance.

Plantains are a member of the banana family, but they have more starch and less sugar than yellow bananas. Due to their starch content, plantains are not eaten raw. While frying plantains won't affect your carb intake, there are healthier ways to prepare them, such as boiling, baking, or grilling.

Although plantains are high in carbohydrates, the resistant starches in green plantains buffer the impact of carbs on blood sugar. Eating small amounts of raw green plantain won't push you out of ketosis. However, ripe or cooked plantains contain significantly more sugar, which can interfere with ketosis and make them unsuitable for a low-carb diet.

Plantains are rich in resistant starch

Plantains are a starchy tropical fruit that look like bananas but are bigger. They are green when unripe but turn yellow and then dark as they ripen. Plantains are a staple in many diets and are a good source of potassium, vitamins A, B-6, and C, and magnesium.

The resistant starch in green plantains has sparked interest for its health benefits. In addition to supporting gut health and blood sugar control, it acts as a prebiotic, helping the growth of healthy bacteria in the colon. This can be beneficial for those with autoimmune diseases as it can help reduce inflammation and prevent immune responses.

Plantains can be a challenging food to include in a low-carb diet due to their high carbohydrate content. A 1/2-cup cooked serving of plantains contains 24 grams of total carbohydrates and 22 grams of net carbohydrates. Most low-carb plans don't allow starchy vegetables like plantains when carb intake is restricted. However, as your carb allowance increases, you may have more flexibility to include plantains in your diet.

While plantains are rich in resistant starch, the cooking method can impact the starch content. Heat and processing convert resistant starches into sugar. Therefore, eating cooked or fried plantain chips can impact blood glucose and insulin levels. To retain the resistant starch in plantains, they need to be consumed raw or dehydrated.

Plantains are a good source of vitamins and minerals

Plantains are a rich source of complex carbohydrates, vitamins, and minerals and are easily digestible. They are high in antioxidants and contain a good amount of vitamin C, which acts as an antioxidant and may help boost your immune system. Plantains are also a good source of vitamin A, with one cup of raw plantain providing 33% of the recommended daily intake.

In addition to vitamins A and C, plantains also contain several B vitamins, including vitamin B6. This vitamin is important for healthy brain function and helps to make hormones like serotonin and melatonin. Plantains also contain minerals like potassium, magnesium, copper, and iron. Potassium is essential for maintaining the cell and body fluids that control heart rate and blood pressure, while magnesium affects over 300 biochemical reactions in the body, including regulating blood pressure and preventing osteoporosis.

Plantains are also a good source of fiber, which promotes bowel regularity and can help reduce the risk of hemorrhoids and diverticular disease. The resistant starch in plantains may also help control blood sugar levels and lower blood pressure.

There are keto-friendly alternatives to plantain chips

Plantain chips are not keto-friendly. A 1-ounce serving of plantain chips can contain between 17 and 25 grams of net carbs, which is not suitable for a low-carb diet. Additionally, the high-temperature cooking process produces acrylamide, a chemical linked to cancer.

However, there are several keto-friendly alternatives to plantain chips that you can enjoy without compromising your ketosis. Here are some suggestions:

• Blackberries: With only six grams of net carbs per cup, blackberries are a delicious and keto-friendly option. They are also rich in phytonutrients and pigments like anthocyanin, which have health benefits such as maintaining normal blood sugar levels and reducing inflammation. Just be sure to avoid dried berries, as they have a much higher carb and sugar content.
• Olives: Olives make a great alternative to mashed plantains, adding a mild yet salty flavor to your keto recipes. One cup of olives has eight grams of net carbs, and they are also a good source of healthy fats, which can reduce your risk of heart disease and fight chronic inflammation.
• Cauliflower: Cauliflower is a versatile vegetable that can be used as a substitute for potatoes and other carby foods. It has a neutral flavor, so it easily adapts to the spices and other ingredients in your meal. A single-cup serving of cauliflower provides three grams of fiber, two grams of net carbs, and two grams of protein.
• Celery Root Chips: Celery root, or celeriac, is a delicious and easy-to-prepare vegetable with a crisp texture, making it an excellent alternative to plantain chips. To make your own celery root chips, simply slice the celery root thinly, coat with olive oil, butter, salt, and pepper, and bake in the oven until crispy.
• Daikon: Daikon is a low-carb radish with only 4.1 grams of carbs per serving. It is also an excellent source of vitamin C, providing 25% of your daily needs. Daikon has additional health benefits, including anti-inflammatory, anti-cancer, and immune-boosting properties, making it a great choice for anyone new to the keto diet.
• Keto-friendly Chips: There are several chip options specifically designed for keto diets. These include pork rinds, keto tortilla chips, pepperoni chips, mushroom chips, and cheese crisps. These alternatives are made with low-carb ingredients and can satisfy your cravings for salty, crunchy snacks.
