Study Notes

Soy

Soy protein has been shown to have a small but statistically significant reduction in both total cholesterol and LDL cholesterol levels in individuals with high cholesterol.
The American Heart Association (AHA) initially recommended consuming 25g/day of soy protein as part of a low-saturated fat diet, to reduce LDL cholesterol by 4–8% and reduce the risk of coronary heart disease.
The US Food and Drug Administration (FDA) proposed in 2017, to revoke the heart health claim status for soy protein foods.
Observational studies have linked higher dietary intake of soy, during childhood and adolescence, to a reduced risk of breast cancer in women.
Soy isoflavones intake has been linked to reduced risk of coronary heart disease.
Soy is a primary source of phytoestrogens called isoflavones, which are similar in structure to natural estrogen and synthetic estrogen.
Studies have shown that consuming 15-60g of soy protein per day, (providing 34-100mg of isoflavones), modestly decreases the frequency and severity of hot flashes in menopausal adults.
The effectiveness of soy in reducing menopausal symptoms appears to be greater in those with a higher frequency of hot flashes at baseline.
Ingestion of soy isoflavones alone might not be as effective as whole soybean.
Soy should be avoided during pregnancy due to potential uterine stimulant effects and malformation in the baby.
Soy should be used with caution in patients with diabetes and are on antihyperglycemic medications.

Fenugreek

Fenugreek is an herb primarily derived from soy and red clover.
Fenugreek is used for symptoms associated with menopause, maintaining bone health, and to promote cardiovascular health.
Fenugreek is a source of phytoestrogens and diosgenin.
Fenugreek may increase breast milk production in breastfeeding mothers.
Fenugreek may help lower blood sugar levels in individuals with diabetes or prediabetes however studies on efficacy are limited and were not of high quality.
The typical dose for increasing milk supply is 2-3 capsules (580-610mg per capsule) 3-4 times per day.
The maximum recommended amount of fenugreek seed is 6g/day.
Fenugreek may have a side effect that causes urine, sweat, and breast milk to smell like maple syrup.
Fenugreek can interact with other medications and may increase the risk of bleeding in patients taking anticoagulants and antiplatelets.

Safety Considerations

Fenugreek should be discontinued at least 2 weeks before elective surgical procedures due to potential risk of hypoglycemia.
Individuals with a history of a liver disorder or allergies to chickpeas or peanuts should avoid using fenugreek.

Black Cohosh

Plant that grows in North America.
Root is active.
Used for PMS, dysmenorrhea, menopause.
May have estrogenic activity but no effect on vaginal epithelium, endometrium, or hormone concentrations.
Might have SERM effects.
Evidence for efficacy is mixed, lacks standardized dosing and has poor methodologic quality.
Some studies suggest improvement of menopausal symptoms.
Some studies showed no difference compared to placebo.
Dose: 40 mg po daily in divided doses.
Long-term effects on cardiovascular disease, osteoporosis, breast cancer, and gynecological cancers are unknown.

Black Cohosh Safety

Common side effects: dyspepsia, headache, and rash.
Serious but rare side effects: weight gain and hepatotoxicity.
Significant drug interactions: lack of data regarding maternal and fetal safety and efficacy with fertility agents; concern for hepatotoxic interactions.
Disease interactions: caution with hormone-sensitive conditions like breast cancer, gynecological cancers.

Black Cohosh Safety Continued

Avoid in patients with aspirin sensitivity.
Contraindicated in pregnancy and lactation due to complications in neonates and mothers, and concern for birth defects.
Caution in those with thromboembolic/cardiovascular disease and hepatic failure or hepatotoxic medications.

Black Cohosh Counseling

Therapeutic effects begin after 2 weeks, with maximum effects within 8 weeks.
Usage longer than 12 months is not recommended.
Anyone experiencing symptoms of liver failure while taking black cohosh should stop and consult a healthcare provider.

Fenugreek

Spice and medicine used in India, China, and Northern Africa.
Found in maple syrup and other foods and beverages.
Used for diabetes, dysmenorrhea, dyslipidemia, and stimulation of breast milk production.
May increase sweat production impacting the milk duct or by phytoestrogens and diosgenin found in fenugreek.
May lower cholesterol due to high fiber content.
May lower blood sugar by increasing glucose-induced insulin release, reducing insulin resistance or high fiber delaying glucose absorption.

Fenugreek Efficacy

Typical dose for increasing milk supply: 2-3 capsules (580-610 mg per capsule) 3-4 times per day.
Maximum recommended amount: 6 grams/day.
Small studies suggest fenugreek may help lower blood sugar in people with diabetes or prediabetes, but most studies were not of high quality.
It's uncertain whether fenugreek can increase milk supply in breastfeeding women; studies have had mixed results.
Fenugreek seems to help most when started a day or two after giving birth, but not all research shows this.
Evidence is too limited to reach conclusions on other health conditions.

Fenugreek Safety

Side effects: hypoglycemia, hypokalemia, and urine, sweat, and breast milk smelling like maple syrup.
High-fiber content can bind with drugs, decreasing absorption.
May increase risk of bleeding in patients taking anticoagulants and antiplatelets.
May interact with antihyperglycemic medications.

Fenugreek Safety Continued

Avoid during pregnancy due to potential uterine stimulant effects and malformation in the baby.
Avoid in individuals with prior allergy to chickpeas and peanuts.
Avoid in individuals with a history of liver disorder.
Caution in patients with diabetes on antihyperglycemic medications.
Discontinue fenugreek at least two weeks before elective surgical procedures.

Phytoestrogens: Soy

Primarily derived from soy and red clover.
Used for symptoms associated with menopause, bone health, and cardiovascular health.
Soy is a primary source of isoflavones, structurally similar to endogenous and synthetic estrogen.
Isoflavones are competitive ligands of in vitro estrogen receptor assays, functioning as SERMs.

Soy Efficacy for Menopausal Symptoms

Consuming 15-60 grams of soy protein, providing 34-100 mg of isoflavones daily, seems to modestly decrease the frequency and severity of hot flashes in some menopausal adults.
Improvement is greater in those with a higher frequency of hot flashes at baseline.

Soy Efficacy for Breast Cancer

Observational studies show higher dietary intake of soy during childhood and adolescence is associated with a lower risk of breast cancer later in life in Asian women.
Western soy intake is too low for this association to be observed; this may be due to genetic differences or differences in quantification of soy intake.
Soy products in supplement form have not been shown to reduce breast cancer risk.

Soy Efficacy for Bone Health

Soy isoflavone mixtures probably have a beneficial effect on bone health in postmenopausal women, but evidence is inconsistent.

Soy Efficacy for Heart Health

AHA initially recommended >= 25 g/day PO of intact soy protein to reduce LDL cholesterol and CHD risk.
FDA proposed to revoke this claim in 2017.
Meta-analysis of 46 soy trials showed small reductions in total cholesterol and LDL cholesterol.
Clinical trial data suggest soy isoflavones alone may not be as effective as whole soybean.
Intake of isoflavones and tofu was associated with a lower coronary heart disease risk in 3 large prospective cohorts of US men and women.
