Oftentimes, the simplest foods are best for your health, and this is certainly the case for nuts, in which Mother Nature has crafted a nearly perfect package of protein, healthy fats, fiber, plant sterols, antioxidants, and many vitamins and minerals.
Research shows that nuts may boost your health in a number of ways at a very easy to achieve “doses.” Eating just one ounce of walnuts a day (that’s about seven shelled walnuts) may be all it takes to take advantage of their beneficial properties.
Here are five reasons to take advantage of these wonderful nuts
1. Cancer-Fighting Properties
Walnuts may help reduce not only the risk of prostate cancer, but breast cancer as well. In one study, mice that ate the human equivalent of 2.4 ounces of whole walnuts for 18 weeks had significantly smaller and slower-growing prostate tumors compared to the control group that consumed the same amount of fat but from other sources.
Overall the whole walnut diet reduced prostate cancer growth by 30 to 40 percent. According to another study on mice, the human equivalent of just two handfuls of walnuts a day cut breast cancer risk in half, and slowed tumor growth by 50 percent as well.
2. Heart Health
Walnuts contain the amino acid l-arginine, which offers multiple vascular benefits to people with heart disease, or those who have increased risk for heart disease due to multiple cardiac risk factors.
Walnuts also contain the plant-based omega-3 fat alpha-linolenic acid (ALA), which is anti-inflammatory and may prevent the formation of pathological blood clots. Research shows that people who eat a diet high in ALA are less likely to have a fatal heart attack and have a nearly 50 percent lower risk of sudden cardiac death.
Separate research showed that eating just one ounce of walnuts a day may decrease cardiovascular risk, and among those at high cardiovascular risk, increased frequency of nut consumption significantly lowers the risk of death.
3. Weight Control
Adding healthful amounts of nuts such as walnuts to your diet can help you to maintain your ideal weight over time. In one review of 31 trials, those whose diets included extra nuts or nuts substituted for other foods lost about 1.4 extra pounds and half an inch from their waists. Eating walnuts is also associated with increased satiety after just three days.
The beneficial dietary fat in walnuts has been shown to improve metabolic parameters in people with type 2 diabetes. Overweight adults with type 2 diabetes who ate one-quarter cup of walnuts daily had significant reductions in fasting insulin levels compared to those who did not, and the benefit was achieved in the first three months.
4. Improved Reproductive Health in Men
One of the lesser-known benefits of walnuts is their impact on male fertility. Among men who consume a Western-style diet, adding 75 grams (a bit over one-half cup) of walnuts daily significantly improved sperm quality, including vitality, motility, and morphology.
5. Brain Health
Walnuts contain a number of neuroprotective compounds, including vitamin E, folate, melatonin, omega 3 fats, and antioxidants. Research shows walnut consumption may support brain health, including increasing inferential reasoning in young adults.
One study also found that consuming high-antioxidant foods like walnuts can decrease the enhanced vulnerability to oxidative stress that occurs in aging, increase health span, and also enhance cognitive and motor function in aging.“
