Following are the major side effects of eating too many walnuts.

Dietary fibers in walnuts provide stomach satiety and control overeating, a major cause of obesity.

As per a one-year study at the Linda University, California individuals who ate 35 grams of walnuts per day for one year didn’t show significant signs of weight gain despite their high calories.

However, overeating walnuts may lead to weight gain because of their high calorific value of 654 calories per 100 grams.

If you are already getting enough calories through other food sources then calories from overeating walnuts may contribute to weight gain.

For proper weight management, eat walnuts in moderation.

Avoid salted walnuts as they increase water retention and fat accumulation.

Avoid roasted walnuts and fried walnuts as the former are deprived of healthy fats, and later may have unhealthy fats.

If the oil used for frying walnuts is unhealthy or contaminated then it’s an even bigger problem.

Walnuts provide many health and beauty benefits as they are abundant in nutrients.

However, avoid walnuts if you suffer from tree nut allergy as they may cause allergic reactions like abdominal pain, upset stomach, diarrhea, trouble swelling, itching of mouth, throat, skin, and other body regions, shortness of breath, wheezing, nasal congestion, and runny nose, etc.

People with a tree nut allergy are likely to be allergic to almonds, pecans, hazelnuts, cashews, and pistachios.

If you experience any allergic reaction or discomfort after eating walnuts, discontinue the use and immediately consult a doctor.

(4) May Cause & Worsen Diarrhea

Dietary fibers in walnuts are natural laxatives that relieve constipation and other digestive problems like abdominal pain, gas, bloating, and flatulence, etc.

Walnuts are at a higher risk of carrying allergens that may worsen the conditions of diarrhea and other digestive problems.

If you have diarrhea, avoid walnuts and consult your doctor.

(5) May Cause Nausea

When our immune system encounters the allergens present in the walnuts, it stimulates the white blood cells to produce histamine.

Histamine is an organic compound involved in primary immune response as it allows the permeability of capillaries to the white blood cells and some proteins and allows them to deal with the allergens.

In small quantities, histamine is not a problem and is even required by our body.

However, overeating walnuts may increase histamine levels in the body, and give rise to allergic reactions like nausea, hives, itchy or flushed skin, red eyes, facial swelling, runny nose and congestion, headache, or asthma attacks.

(6) Not Safe For Pregnant And Nursing Women

When consumed in moderation and doctor’s supervision, walnuts may help in maintaining a healthy pregnancy.

Omega-3 fatty acid and the folic acid in the walnuts promote the brain development of the fetus, and folic acid reduces the risk of neural tube defects like spina bifida.
