Is Nuts Safe During Pregnancy? (Updated 2026 Guide)
Updated April 13, 2026
The Answer
Yes, nuts are safe and highly beneficial during pregnancy. With over 88% of nut products earning an A grade, most plain and lightly seasoned nuts are excellent choices for pregnant women.
Nuts are one of the best snack choices during pregnancy, providing essential nutrients like omega-3 fatty acids, protein, and folate that support fetal brain development. Walnuts are particularly beneficial for omega-3s if you don't eat fish. The main concerns are flavored varieties containing artificial dyes or high fructose corn syrup, which should be limited.

Ingredients to Watch Out For in Nuts
These are the most common flagged ingredients across 7,683 nuts products we analyzed.
fructose
CAUTION
Fructose is a simple sugar found naturally in fruits and added to many processed foods and beverages as high fructose corn syrup. May program offspring for metabolic dysfunction when consumed in excess during pregnancy, with animal studies showing effects on insulin resistance, blood pressure, and neurodevelopment.
Found in 78 of 7,683 products (1%)
red 40
CAUTION
Red 40 is a synthetic red food coloring. May affect neurobehavioral development based on animal studies at high doses.
Found in 37 of 7,683 products (0%)
yellow 5
CAUTION
Yellow 5 is a synthetic yellow food coloring. Has shown embryotoxic effects in recent animal studies at high doses.
Found in 22 of 7,683 products (0%)
horseradish
AVOID
Horseradish is a pungent root vegetable used as a condiment. Contains compounds that may cause digestive irritation and has shown developmental toxicity in animals.
Found in 17 of 7,683 products (0%)
blue 1
CAUTION
Blue 1 is a synthetic blue food coloring. Has limited human pregnancy data with possible neurobehavioral effects in animal studies.
Found in 13 of 7,683 products (0%)
high fructose corn syrup
CAUTION
High fructose corn syrup is a sweetener derived from corn starch and widely used in processed foods and beverages. Has been associated with placental insufficiency, fetal growth restriction, and metabolic programming of offspring in animal studies, and with gestational diabetes and preeclampsia in epidemiological studies of humans.
Found in 9 of 7,683 products (0%)
alcohol
CAUTION
Alcohol is an intoxicating substance in beverages. Causes fetal alcohol spectrum disorder with lifelong physical and cognitive problems. No safe level exists.
Found in 7 of 7,683 products (0%)
artificial color

Your Questions Answered
Can pregnant women eat nuts?
Yes, pregnant women can and should eat nuts as part of a healthy diet. Nuts provide protein, healthy fats, fiber, and essential nutrients like folate and omega-3 fatty acids that support fetal development. Research from Johns Hopkins recommends nuts as one of the top snack foods during pregnancy. Unless you have a nut allergy, there's no reason to avoid them.
What are the risks of nuts during pregnancy?
Plain nuts pose virtually no risk during pregnancy and are considered highly beneficial. The only concerns relate to flavored varieties containing artificial dyes (Red 40, Yellow 5, Blue 1) or high fructose corn syrup, which have shown potential effects on fetal development in animal studies. Stick to plain or lightly salted nuts to avoid these additives. If you have a nut allergy, avoid nuts entirely and consult your healthcare provider.
Which nuts should be avoided in pregnancy?
You don't need to avoid any type of nut during pregnancy unless you have an allergy. The NHS confirms that peanuts and tree nuts are safe. However, you should avoid heavily processed nut products with artificial colors and sweeteners. Wasabi flavored almonds, candy coated nuts, and products with long ingredient lists often contain additives that are best limited during pregnancy.
What kind of nuts to eat during pregnancy?
All nuts are beneficial, but walnuts are particularly recommended because they contain omega-3 fatty acids that support your baby's brain development. Almonds provide calcium and vitamin E, cashews offer iron and zinc, and pistachios are rich in protein and fiber. Aim for variety and choose plain, roasted, or lightly salted versions. A daily handful provides excellent nutrition without excessive calories.
How many nuts can I eat per day while pregnant?
A serving of about 1 ounce (roughly a small handful or 23 almonds) daily is a healthy amount during pregnancy. This provides beneficial nutrients without excessive calories. You can safely eat nuts every day as a snack or add them to meals. Studies have linked regular nut consumption during pregnancy to improved cognitive development in children.
Are flavored nuts safe during pregnancy?
Lightly flavored nuts with natural seasonings like sea salt, herbs, or mild spices are generally fine. However, heavily flavored varieties like wasabi soy almonds often contain artificial dyes (Red 40, Yellow 5) that have shown potential neurobehavioral effects in animal studies. Check ingredient labels and choose products without artificial colors or high fructose corn syrup for the safest options.
How Do We Score Products for Pregnancy Safety?
We analyze each product's ingredients and category to flag known risks and provide cautionary notices for general category safety concerns.
A - Safe
Excellent choice! All ingredients are considered safe during pregnancy.
What to do: Use with confidence.
B - Likely Safe
Pretty much safe with very minimal risk. Some ingredients may have limited pregnancy studies, but no significant safety concerns have been identified.
What to do: Use with confidence.
C - Limit
Contains ingredients with some pregnancy considerations. Research shows these ingredients may have limited safety data, potential for minor hormonal effects, or require caution based on animal studies.
What to do: Use sparingly and consider safer alternatives when available.
D - Caution
Similar to C grade but contains multiple cautionary ingredients. The combination increases overall concern.
What to do: Try to avoid if that makes you feel better. If you've already used it, no need to panic.
F - Avoid
Contains ingredients with established risks during pregnancy. Research shows these can cause birth defects, developmental harm, or serious maternal complications.
What to do: Do not use during pregnancy. If you've already used it, don't worry - contact your OBGYN if concerned.
