Important Tips When Eating Oysters
Avoid Overconsumption:
Oysters are highly nutritious, but eating too many can lead to excess zinc and cholesterol. Just 170 grams of oysters can contain up to 85mg of cholesterol.

Limit Raw Oysters:
Whether wild-caught or farmed, raw oysters can harbor parasites and bacteria, increasing the risk of gastrointestinal infections, cholera, or parasitic infestations.

Use Mustard in Moderation:
Mustard complements seafood by masking its fishy odor and enhancing flavor. However, excessive mustard can irritate the nasal and throat lining and cause stomach discomfort, especially for those with digestive issues or gastritis.

Enjoy oysters responsibly to reap their health benefits while minimizing potential risks.
