Walnut also contains alpha-linolenic acid (ALA), the plant-based omega-3 fat, that is anti-inflammatory and can prevent pathological blood clots formation. The study shows that individuals who eat a diet high in ALA are less prone to have a fatal heart attack and have an approximately 50% lower risk of sudden cardiac death.

Consuming just 4 walnuts per day has been found to significantly increase blood levels of heart-healthy ALA, and walnut intake supports “good” cholesterol levels.

  1. Cancer-Fighting Properties

Walnuts can help decrease not just the risk of prostate – but breast cancer, too. In one research, mice who ate the humanoid correspondent of 2.4 ounces of walnuts for 18 weeks had considerably smaller and slower-growing prostate cancer compared to the control group, which consumed the exact same amounts of fat thanfrom other sources.

Overall the whole walnut diet decreased prostate cancer development by 30 – 40%. According to another research on mice, the human correspondent of only 2 handfuls of walnuts per day cut breast cancer risk in 1/2, and slowed tumor development by 50%, too.

Moreover, overweight people with type 2 diabetes who consumed 1/4 cup of walnuts a day had significant decreases in fasting insulin levels compared to individuals who didn’t, and this benefit was reached in the first 3 months.

” Eat Them Whole, Including  The Skin”, Say Scientists

Experts are convinced – more than ever before – about the walnuts benefits when eaten in the whole form, including their skin. We now know that around 90 percent of the phenols in walnut are found in its skin, including phenolic acids, flavonoids, and tannins.

Certain websites will encourage you to eliminate the walnut skin – that whitish, sometimes flaky, sometimes waxy, farthest part of shelled walnut. There could be slight bitterness to this skin, and that is often the reason that some websites give for removing it.

Nevertheless, Your Health Tubers encourage you not to remove this phenol-rich portion.
