Eat healthy nuts, “3 nos” to keep in mind
1Do not eat nuts in excess
The fat content of nuts is basically 46%~76%. Although most of them are unsaturated fatty acids, excessive intake will also lead to excessive calories. Therefore, although nuts are nutritious, they should not be greedy. You must control the amount when you eat them.
According to the “Dietary Guidelines for Chinese Residents”, it is sufficient to eat 50-70 grams of nuts per person per week, which is an average of about 10 grams per day. If you accidentally eat too much, you need to reduce the consumption of three meals a day to avoid obesity.
2 Don’t eat damp and moldy nuts
Because of frequent exposure to air, bulk nuts are susceptible to moisture and mildew, and may even produce highly toxic aflatoxins. If you eat food contaminated with it for a long time, it is easy to cause DNA changes and induce liver cancer. Even 1mg of aflatoxin can cause cancer; if 20mg is ingested at one time, it can even directly cause the death of an adult!
Therefore, if you eat moldy, bitter nuts, be sure to spit them out and rinse your mouth. If a few nuts are moldy, it is best to throw away the whole package, because Aspergillus flavus is spread in the form of spores, and food is easily involved in moldy, but it is not visible to the naked eye.
3 Don’t eat nuts that taste too heavy
First of all, the salt added to nuts with heavier taste tends to be larger. Long-term consumption can easily lead to excessive sodium intake, which will cause damage to blood vessels, heart, and kidneys; Flavor, saccharin and other substances will be added to the nuts in processing. Excessive consumption of these ingredients is not good for health;
Furthermore, heavy flavors may mask the spoiled taste of nuts, which can be harmful to health after consumption. Therefore, it is best to choose the original flavor of nuts.
