What are the benefits and drawbacks of eating sweet potatoes for fitness

Moderate consumption of sweet potatoes during exercise can help replenish energy and nutrients, but excessive consumption may cause gastrointestinal discomfort. Sweet potatoes are rich in dietary fiber, vitamin A, complex carbohydrates, and minerals such as potassium, making them suitable as energy supplements before and after exercise. However, it should be noted that their high sugar content may affect the blood sugar levels of some people.

1. Energy Supply

Sweet potatoes' complex carbohydrates can slowly release energy, helping to maintain exercise endurance. Its glycemic index is lower than that of refined rice and flour, making it suitable as a source of carbohydrates before exercise to avoid low blood sugar during training. Moderate consumption after exercise can promote muscle glycogen recovery, and it is more effective when paired with protein foods.

2. Nutritional supplementation

Sweet potatoes are rich in vitamin A and vitamin C, which help alleviate oxidative stress after exercise. Potassium can regulate electrolyte balance and prevent muscle spasms. Dietary fiber can promote intestinal health, but excessive intake before and after exercise may cause bloating.

3. Blood sugar fluctuations

Although sweet potatoes are classified as low to medium sugar foods, consuming more than 200 grams at a time may cause significant fluctuations in blood sugar levels. Diabetes patients or people in the fat reduction period should control the consumption, and it is recommended to mix high-quality protein and healthy fat to delay sugar absorption.

4. Gastrointestinal burden

Dietary fiber and resistant starch in sweet potatoes may increase digestive burden. Avoid excessive consumption within one hour before and after high-intensity training, as it may cause bloating or acid reflux. People with weak gastrointestinal function can choose to consume it by steaming until soft and tender.

5. Allergy risk

A minority of people are sensitive to calcium oxalate in sweet potatoes, and may experience oral pain or skin itching after consumption. If you need to supplement carbohydrates during exercise, those who are intolerant to sweet potatoes can use yam, oats, and other alternatives.

Fitness enthusiasts can use sweet potatoes as a staple food substitute, with a recommended daily intake of 150-300 grams and a preference for steaming or baking. Pairing with protein foods such as chicken breast and eggs after exercise can optimize nutrient absorption. Individuals with insulin resistance or digestive system disorders should adjust their intake under the guidance of a nutritionist. Pay attention to individual tolerance, and adjust dietary structure promptly if bloating or abnormal blood sugar occurs.
