Are nuts considered poison if eaten incorrectly?

A study published in the American Review of Food Science and Nutrition found that different nuts have different effects on regulating blood lipids, including:

The first place in reducing total cholesterol: pistachios.

No. 1 in reducing LDL cholesterol (bad cholesterol): Cashews.

No. 1 in improving HDL cholesterol (good cholesterol): Peanuts.

Although nuts are good, you need to be careful in choosing the following three types:

1. Moldy and bitter nuts

If the nuts are bitter and moldy, aflatoxins may be present.

Aflatoxin is extremely toxic, teratogenic, and carcinogenic. This toxin can damage the liver. Poisoning may cause vomiting, abdominal pain, hepatitis, edema, and jaundice in mild cases. In severe cases, it may cause liver cancer or even direct death.

Therefore, for the sake of safety, if you eat moldy or bitter nuts, you should spit them out immediately and rinse your mouth. If the rinsing is not clean, you can brush them with a toothbrush again. If stored nuts are moldy or have an off-color color, do not eat them again.

2. Nuts with spicy flavor

The content of unsaturated fatty acids in nuts is usually high. If they are stored for too long or in improper storage methods, they are prone to oxidation and rancidity, resulting in a bad smell.

At this time, not only does the flavor of the nuts deteriorate, but the rancid products of the oil produced, such as small-molecule aldehydes and ketones, also threaten health. Consuming large amounts may cause diarrhea or liver damage.

3. Nuts with too strong flavor

Many nuts with strong taste and aroma are due to the addition of flavors, sugar, salt, oil and other substances during processing. Some friends cannot stop eating nuts. If the intake of these substances exceeds the limit, it will increase the burden on the body.

When purchasing, you can pay attention to the ingredient list and nutritional label on the outer packaging. You can give priority to products with only nuts in the ingredient list, or products with a low amount of added oil, salt, and sugar.

Different types of nuts have their own particularities in choosing or eating them.

1. Pistachios: buy green ones

The average adult can eat 10 grams of nuts every day, which is about 10 pistachios. Pistachios contain monounsaturated fatty acids, which are good for your heart.

Naturally mature pistachios have a creamy yellow shell and an emerald green kernel. If the kernels are yellowish brown, it may have been stored for a long time.

2. Cashew nuts: People with allergies should eat with caution

8 cashew nuts weigh approximately 10 grams. Cashews are rich in monounsaturated fatty acids, which are beneficial to cardiovascular and cerebrovascular health. However, some people may experience allergic reactions after eating cashew nuts, and such people should be careful to avoid eating them.

3. Peanuts: Peel and eat them if you have thick blood.

The average adult can eat 15 peanuts a day. Peanuts contain a variety of vitamins, unsaturated fatty acids, resveratrol, and have antioxidant effects. Peanuts can be steamed, boiled, or stewed. It is best not to eat fried peanuts. High-temperature frying will destroy the nutrients in peanuts.

Peanut skin (red skin) is helpful to improve blood coagulation ability. If you have a tendency of coagulation or have high blood viscosity, it is best to remove the red skin of peanuts before eating them.
