Do isoflavones lower cholesterol?

Results: Soy isoflavones significantly decreased serum total cholesterol by 0.10 mmol/L (3.9 mg/dL or 1.77%; P = 0.02) and LDL cholesterol by 0.13 mmol/L (5.0 mg/dL or 3.58%; P < 0.0001); no significant changes in HDL cholesterol and triacylglycerol were found.

Can soy raise your cholesterol?

Possibly. Although eating soy-based foods can slightly reduce your low-density lipoprotein (LDL, or “bad”) cholesterol level, the American Heart Association has concluded that soy doesn’t significantly lower cholesterol.

How does soy protein lower cholesterol?

Soy protein containing isoflavones lowered cholesterol significantly more than soy protein without isoflavones in humans. Crouse et al17 concluded that the cholesterol-lowering effect of soy protein is entirely due to isoflavones.

What is a good Colesterol number?

Cholesterol levels for adults Total cholesterol levels less than 200 milligrams per deciliter (mg/dL) are considered desirable for adults. A reading between 200 and 239 mg/dL is considered borderline high and a reading of 240 mg/dL and above is considered high. LDL cholesterol levels should be less than 100 mg/dL.

What does a high LDL cholesterol mean?

When you have high LDL cholesterol levels, it means you are at greater risk for cardiovascular disease like heart attack and stroke. The plaque formed by this fatty substance on the inner walls of arteries can block or restrict blood flow.

Is it safe to take soy isoflavones?

Soy isoflavones are generally considered safe [12]. Numerous randomized controlled trials in menopausal women reported that side effects were not significantly different between soy isoflavone and placebo groups [2][13].

Is coffee bad for cholesterol?

While coffee does not contain cholesterol, it can affect cholesterol levels. The diterpenes in coffee suppress the body’s production of substances involved in cholesterol breakdown, which causes cholesterol to increase. Specifically, coffee diterpenes may cause an increase in total cholesterol and LDL levels.

How are isoflavones used to treat high cholesterol?

High cholesterol: The clinical research evidence strongly suggests that isoflavones from soy reduce bad cholesterol called LDL. It’s important to note that ONLY the protein-based food sources of isoflavones such as tofu, tempeh, and other soy products were found to lower cholesterol; isoflavone supplements were not found to be effective.

Are there any side effects to taking soy isoflavones?

Hypothyroidism may be worsened when using soy isoflavones. Those with kidney stones should avoid taking soy isoflavones as they may increase a chemical, called oxalates, that contributes to kidney stones.

What are the benefits and side effects of isoflavones?

This means that they reduce damage due to oxygen (such as that caused by free radicals) and may help fight against certain types of cancer. There have been multiple studies on the benefits and safety of isoflavones.

How are isoflavones used in soy protein supplementation?

Several studies, of both animals and humans, have shown that soy protein supplementation (containing isoflavones) may reduce both the total and low density (LDL) cholesterol. 2
