Health Benefits Of Kimchi

1. May Improve Gut Health

Fermented foods like kimchi contain lactic acid bacteria (LAB), which have probiotic properties (2). Probiotic-rich foods may improve gut bacteria and enhance digestive health (3). Besides, an increased intake of fermented foods was found to improve intestinal health, treat infectious diarrhea, and reduce inflammation (4). A study conducted by Hiroshima University (Japan) found that the probiotic activity of lactic acid bacteria may also help treat constipation (5). Another study suggests that lactobacillus strains found in kimchi have antimicrobial activity against food-borne pathogens (6). Moreover, probiotics may also be beneficial in treating and preventing gastrointestinal  diseases (7). Adding fermented foods like kimchi to your diet can help reduce gastrointestinal disorders like irritable bowel syndrome and colon inflammation symptoms. Maintaining a healthy gut flora is important for overall health.

2. Has Anti-Inflammatory Properties

HDMPPA, an active compound in kimchi, may help reduce inflammation (8), (9). Besides, Lactobacillus paracasei, a lactic acid bacterium isolated from kimchi, exhibits a similar effect and helps relieve colitis (inflammatory reaction in the colon) symptoms (10). The bioactive compounds in kimchi may also help reduce the symptoms of Alzheimer’s disease by suppressing inflammation (11).

3. May Boost The Immune System

A 17-week study showed that probiotics found in foods like kimchi can boost immune health (12). These immune-regulating probiotics include Lactobacillus sakei and Lactobacillus plantarum (13), (14). However, more studies are warranted to understand this benefit of kimchi.

4. May Help With Weight Loss

Consuming kimchi was found to reduce bodyweight in overweight and obese individuals. In fact, fermented variety had shown more significant results than fresh kimchi (15). Furthermore, a study conducted on 114 adults for 12 weeks found that L. sakei present in kimchi may help reduce body fat in people with obesity (16). Besides, the low calorific value of this Korean dish may also contribute to weight loss. Another study by Ajou University School of Medicine (Republic of Korea) indicated that kimchi may improve metabolic rates (17).

5. May Improve Heart Health

HDMPPA, the bioactive compound in kimchi, has antioxidant and anti-atherosclerotic effects. These properties may help reduce the risk of heart disease (18). Besides, fermented kimchi was found to have more beneficial effects than the fresh variety on factors associated with cardiovascular diseases (19). Furthermore, kimchi may also decrease LDL cholesterol and serum triglyceride levels (20). A study found that mice fed with kimchi had lower fat levels than those given a high cholesterol diet (21). In addition, the anti-inflammatory properties of kimchi may help reduce the risk of heart diseases (22), (23).

6. Helps Regulate Blood Sugar Levels

A pilot study conducted on 21 individuals with prediabetes found that kimchi intake may improve glucose tolerance and lower fasting blood glucose levels. The fermented dish may also increase insulin sensitivity and lower blood pressure (17), (24). Another study on rats conducted by the Seoul National University (Republic of Korea)found that dietary baechu kimchi has anti-diabetic effects. Kimchi was found to protect against diabetes even when the rats were fed a high-fat diet. However, consume kimchi with a low or normal fat diet for better results (25). Insufficient Evidence For

7. May Prevent Yeast Infections

Lactobacillus strains that are isolated from kimchi have probiotic, anti-inflammatory, and antimicrobial properties. Their basic probiotic functions include breaking down (hydrolase activity) bile salts, producing hydrogen peroxide, and resisting heat at 70oC for 60 seconds. These strains help treat infections caused by Candida albicans and Gardnerella vaginalis species (26), (27). Their anti-inflammatory properties may help treat and prevent bacterial vaginosis (bacterial overgrowth in the vagina) and vulvovaginal candidiasis (a yeast infection of the vagina). Besides, Lactobacillus bacterium was also demonstrated to improve mucosal health.

8. May Protect Against Oxidative Stress

Kimchi added with black raspberry juice powder is a rich source of antioxidants, which may help protect the cells from oxidative damage (28). This traditional side dish may also protect the liver from oxidative effects. Besides, methanol extracts of kimchi also possess radical scavenging ability. In a study, over-ripened kimchi had shown the strongest antioxidant activity compared to fresh and optimally ripened kimchi (29).

9. May Have Anti-Aging Properties

Kimchi may exhibit anti-aging potential. Its anti-inflammatory and radical-scavenging activities may help slow down aging by regulating genes (30). In addition, oral administration of Lactobacillus strains from kimchi was found to prevent atopic dermatitis (red and itchy skin) in mice models (31).

10. May Have Anti-Cancer Potential

The bioactive compounds in kimchi, like beta-sorbitol, have anti-cancer potential (32).The anti-inflammatory, antioxidative, and anti-mutagenic properties of kimchi may also help treat cancer. However, more research is warranted to understand this activity of kimchi. Consuming anything in excess may lead to undesirable effects, and so is the case with kimchi. Continue reading to learn about the side effects of excess kimchi intake.

Side Effects Of Kimchi

Consuming kimchi is generally considered safe. However, kimchi products made using contaminated groundwater (high chlorine content) may cause acute gastroenteritis (an intestinal infection) in some individuals (33). Besides, kimchi intake may also cause food-borne illnesses in some people (34). It is important to prepare and store kimchi appropriately to avoid the growth of pathogenic bacteria (35). Besides, the high sodium content in kimchi is linked with blood pressure and may not be suitable for people with heart disease. This Korean staple may also cause bloating or an upset stomach due to its high levels of probiotics. Kimchi has a very good commercial presence. However, you can also prepare this side dish at home.

What You Need

• Napa cabbage – 2 medium heads (6-8 pounds)
• Coarse salt – 1½ cups
• Coldwater – 1 gallon + ½ cup

• Fish sauce – 1 teaspoon (optional)
• Finely ground salt – 2 teaspoons

Process

1. Prepare Napa cabbage.

a. Rinse heads under cold water and drain. b. Cut away spoiled or damaged spots. c. Cut Napa cabbage into quarters and remove the core from each. Chop the quarters into 2-inch pieces.

2. Prepare salt cabbage

a. Prepare a saltwater solution of ½ cup coarse, non-iodized salt, and 1-gallon cold water in a large mixing bowl. b. Dip cabbage pieces briefly in the solution. c. Drain and place the cabbage pieces in a bowl. Sprinkle 1 cup of non-iodized salt over them and massage well. Cover the bowl and leave them at room temperature for 3 to 6 hours (a longer duration will make it saltier). d. Wash the cabbage pieces 3 to 4 times with cold water to rinse off the salt. Place them in a colander for at least 30 minutes to drain excess water.

3. Prepare seasonings

a. Add sweet rice flour to ½ cup water in a small saucepan. Bring to a boil and set aside to cool. b. Peel and finely mince (or use a blender with a small amount of water) the garlic and ginger. Mix with the flour paste and add Korean red pepper powder. c. Trim green onions, and peel radish and Asian pear (if desired). Cut them all in Julienne style or into matchsticks about 1 inch in length. d. Put on disposable food handler gloves, and mix the seasoning paste and Julienned vegetables in a large bowl. Add fish sauce and mix to create a spicy veggie paste. Add salt as needed. e. Combine the cabbage with the spicy veggie paste and mix well. 4. Pack kimchi tightly into a container, minimizing air exposure and encouraging brine formation. Fill the container until 2/3rd and cover tightly. 5. Place in the refrigerator and let it ferment for 3 to 4 days. This may be preferred especially during hot weather. You can also place the container in a well-ventilated location with a relatively constant room temperature (around 68°F). Ferment only 1 to 2 days at room temperature, tasting it daily until it reaches the preferred tangy taste and desired texture. 6. Cover fermented kimchi tightly and store in the refrigerator. Kimchi may become sourer over time. Discard if you observe surface mold. Note: Kimchi can also be eaten fresh without fermentation. You can eat kimchi as it is or as a side dish.
