Potatoes Are Healthy

Potatoes are highly energy-packed, gluten-free, and fat-free, high-quality carbs (26 grams) that your body needs for fuel. With only 110 calories per serving, potatoes satisfy hunger and provide three grams of protein.

When Prepared Properly and Kept Away From a Deep Fryer, Potatoes Can Be Quite Healthy

Why is protein a big deal? Protein helps build strong muscles so you can perform your best all day. Potatoes, including sweet potatoes, are also full of nutrients your body uses to function well. An entire potato is edible, including the skin.

Vitamins

They contain 45% vitamin C for iron absorption and collagen production and 10% vitamin B6 for carb and protein metabolism.

Potassium (18%)

Potatoes contain more potassium than bananas. This electrolyte promotes healthy muscle function and helps lower blood pressure by balancing itself with sodium. When your blood pressure stabilizes, the chance of heart disease and stroke decreases.

Fiber (8%)

Fiber has many health benefits, such as regulating blood cholesterol and glucose levels, promoting regular bowel movements, and making you feel full longer. The potato skin provides 50% of dietary fiber.

The fiber in potatoes consists of soluble and insoluble fiber, or resistant starch, gentler on the intestinal tract, producing less gas. This unique starch acts like a prebiotic that promotes the growth of good bacteria, minimizing the symptoms of irritable bowel syndrome or constipation.

Iron (6%)

A large potato can contain 3.2 mg of iron, producing proteins that carry oxygen throughout the body. Sweet potatoes have slightly less (2.1) but are still iron-rich. Potatoes are a perfect food choice for individuals with iron-deficiency anemia.

Antioxidants

Potatoes contain antioxidants to protect the body’s cells from damage due to stress. Examples of antioxidants include Vitamins C and E, beta-carotene, manganese, selenium, and coenzyme Q-10.

How Long Do Potatoes Last?

How long potatoes last varies on different factors. First, buy the freshest batch you can find, preferably without blemishes or eyes. Potatoes should have firm, tight skins and smell earthy.

Potatoes must stay dry to avoid spoiling. Wash them only before you plan to cook them.

Storage of Potatoes

  1. Undercooked potatoes can have a long shelf-life if you store them appropriately. Raw potatoes thrive in cooler temperatures (50 degrees) for two to three months or one to two weeks at room temperature. If you grow potatoes, store them in a room between 44 and 55 degrees Fahrenheit and humid for about two weeks so they can cure.
  2. To keep them fresh longer, store potatoes in cool locations but not in the refrigerator or freezer. According to an associate professor at Iowa State University, temperatures below 50 degrees convert the starch to sugar, compromising a potato’s quality and taste. Potatoes can also darken early at lower temperatures.
  3. Store potatoes in a container that allows air circulation, such as a basket or mesh bag. If they come in a mesh bag, keep them in there.
  4. Place potatoes away from onions and apples because they release gasses that can mature each other too early.
  5. Remove tin foil from cooked potatoes before placing them in the refrigerator.

Store Potatoes in Cool, Dry Places to Keep Them Preserved

Type of Potato

Different types of potatoes mature at various rates. To keep potatoes longer, the varieties to choose from are Yukon Gold and Gem, Elba, Burbank Russet, Fingerling, Red Pontiac and Chieftain, Khatadin, All Blue, German Butterball, and Kennebec.

How to Tell If a Potato Is Going Bad

Sometimes raw potatoes absorb too much light or heat and start to spoil. The best way to store potatoes is in dark and cool places, such as your pantry or cabinet. After about two weeks, they will turn soft or grow sprouts.

Soft potatoes can still be good if there are no other flaws. The following conditions can indicate you have a rotten potato.

They Have Mold

Growing mold anywhere on the potato would indicate it is not edible. Mold spores can spread contaminating the raw potato, so cutting off the moldy parts you can see will not eliminate all mold. Any potatoes with a musty smell are unfavorable for consumption. Don’t eat moldy potatoes.

Sprouted Potatoes

Large potato sprouts that are long and wide signify that the vegetable is too ripe to eat. They

pull nutrients and sugars from the spud, wrinkling and shrinking it. It is safe to eat a sprouted potato after you remove each sprout, which contains harmful chemicals (solanine and chaconine).

Potatoes that Have Sprouted May Still Be Edible - if the Sprouts are Very Small and are Removed. That Said, I’d Opt for a Different Potato.

They Are Green

Have you ever noticed a potato with green skin? That green color is evidence of solanine, which can cause unpleasant symptoms , such as nausea, headaches, fever, and neurological issues. Solanine increases with light exposure and causes a bitter taste. If there are only a few spots on the skin, it is okay to peel the skin or trim around them, which is where the chemical compounds congregate.

Most people do not become sick after eating a small amount of solanine. However, there is no guarantee the potato will be safe to eat. If the potato tastes bitter, toss it. Children are most susceptible to gastrointestinal symptoms and should not eat green potatoes.

Eating less than five grams per body weight of a green potato has been proven to have little to no symptoms, depending on the individual. Cooking them will not kill the toxins, so it might be best to discard them.

They Are Soft and Mushy

Soft potatoes that seem dry and shriveled up may have lost too much water and nutritional value. They are 80% water, and losing some is natural. Loss of excessive moisture may dehydrate them to the point of spoilage.

Black spots may not directly indicate the potato is rotting unless you smell an odor. At that point, toss it out. Sweet potatoes that are soft, mushy, and have a discoloration are not edible.

They Wrinkle and Sag

Just like humans, potatoes will begin to sag and wrinkle over time. When this happens, the other potatoes around them may suffer as well. Mushy potatoes lose flavor and are no longer nutritious.

They Stink

Potatoes with a bitter or moldy smell are not suitable for eating or cooking. The odor originates from the chemical compound solanine. Really rotten potatoes will smell like a decomposing body and are not safe to inhale. Toss them immediately.

Soft Potatoes and Cooking

Are soft potatoes still good to cook and eat? Yes, but there are exceptions. It is okay to cook soft potatoes, as long as they are not mushy, green, moldy, or contain sprouts. Soft potatoes with green skins are not fit for cooking or baking because of their bitterness.

Soft spuds are perfect as mashed potato, twice-baked potatoes, sweet potato casserole, or soups. If the potatoes are too mushy, they lack nutrients and taste, rendering them unsuitable for eating. Eat cooked potatoes within four days to prevent bacteria from growing.

How to Cook Soft Potatoes

  • To enhance flavor, saute your soft potatoes with olive oil or butter and seasoning, such as basil, chives, and sage.
  • If you like to make potato chips, soak raw potato in water overnight to remove excess starch, preventing them from sticking together during frying.
  • Peel the potatoes and steam them before frying to make them tender inside and crispy on the outside.

Frequently Asked Questions

Here are some answered questions that you might find beneficial.

What Will Happen If You Eat a Bad Potato?

A cooked potato carries a risk of contamination from bacteria the longer they sit. Illness can occur from salmonella, botulism, listeria, and staphylococcus. You may develop nausea, vomiting, diarrhea, abdominal cramps, muscle cramps, and fever. Throw them out after four days.

Will One Rotten Potato Ruin the Entire Bunch?

If you catch it early enough, you may be able to save the rest of the batch by removing the rotten potatoes. However, if you find one spoiled potato in the bag with multiple soft spots or dark spots, you’re better off not cooking from that batch of potatoes.

Is It Okay to Store Potatoes In the Freezer?

Yes, you can store potatoes in the freezer, but it is not wise. Freezing them can alter their taste and quality. The optimum temperature for potatoes is between 40 and 50 degrees Fahrenheit.

Can Sweet Potatoes Go Bad?

Yes. Like regular potatoes, yams can change color and get soft and mushy. They also grow mold and sprouts, so check them carefully at the store. Store them as you would other potatoes.

Can You Eat Raw Potatoes?

Raw potatoes are safe to eat if there are no dark or green spots, sprouts, or moldy areas. Keep in mind that it may be challenging for the gut to digest.

Since Potatoes Have Carbs, Can Diabetics Eat Them?

Yes, individuals with diabetes can eat potatoes because of the type of carbs in them. Potatoes are starchy vegetables that contain complex carbohydrates that the body takes longer to oxidize. Your blood sugar can still rise but is easier to maintain. As with any starchy food, eat potatoes in moderation.
