1. About Nuts update

This is already the third year of the About Nuts initiative. The goal of the initiative is still to inform consumers and professionals about the health aspects of peanuts and nuts and about the about the research developments in this area. However, the scope of About Nuts has been broadened rapidly over the years. At the moment the About Nuts initiative is active in six different countries, and newsletters are sent to consumer press and professionals in the Netherlands, Germany, England, Switzerland and Austria. The newsletters, recipes and background information on the health aspects of peanuts and nuts can also be found on the website: www.aboutnuts.com.

2. Snacking nuts can benefit your cholesterol

Nuts fit perfectly in a cholesterol-lowering diet. This is again the outcome of two recent studies. These studies show that by eating a portion of macadamia nuts and pistachio nuts a day you can reduce your LDL cholesterol levels considerably.

What is cholesterol?

Cholesterol is one of the body fats. There are two types of cholesterol: a ‘good’ type called high-density lipoprotein (HDL) and a ‘bad’ type called low-density lipoprotein (LDL). The ‘bad’ type narrows your arteries while the ‘good’ type cleans your arteries. Too much ‘bad’ cholesterol in your blood is not a disease in itself, but can lead to the hardening and narrowing of your arteries and therefore contribute to the development cardiovascular diseases (CVD).

The study

In the present studies, either pistachios or macadamias were eaten on a daily basis by the participants to see if this would affect their cholesterol levels in a positive way. The respondents in the macadamia study included 43 grams of macadamia nuts in their daily diet for five weeks. As a result, their total cholesterol and LDL cholesterol was lowered by 9 per cent. The respondents in the pistachio study incorporated 60 grams of pistachio nuts in their daily diet for four weeks. The 15 participants of the pistachio study were able to decrease their LDL cholesterol by 14 per cent.

Claim

Both studies showed that including nuts in the daily diet can have significant heart health benefits. The FDA has even allowed the heart health claim for tree nuts: "Scientific evidence suggests but does not prove that eating 43 grams per day of most nuts, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease.”

When is your LDL cholesterol too high?

  • Ideal LDL cholesterol level: less than 5.0 mmol/l
  • Mildly high LDL cholesterol level: between 5.0 to 6.4 mmol/l
  • Moderately high LDL cholesterol level: between 6.5 to 8.0 mmol/l
  • Very high LDL cholesterol level: above 8.0 mmol/l

3. The potential role of nuts in the prevention of cancer

Cancer is the second most common cause of death in Europe for both men and women. High consumption of fruit and vegetable is one of the most important ways to reduce the risk of cancer. Many of the compounds in fruit and vegetables that are said to reduce the risk of cancer can also be found in peanuts and nuts.
Researchers have recently looked into the role of nuts in the prevention of cancer. The research, which was published in the British Journal of Nutrition, concluded that there are numerous nutrients and mechanisms of action in nuts that could reduce the risk of cancer. Two compounds that could play a positive role are the antioxidants vitamin E and zinc, which are also to be found in all types of nuts. Furthermore, numerous other factors also help, such as the high fibre content of almonds, walnuts and pistachio nuts, together with the high flavonoid and polphynol content in almonds, pine nuts, walnuts and pecans and the folic acid in pine nuts, almonds and hazelnuts.

The researchers concluded that, although there are very few studies that actually analysed the relationship between nuts and the risk of cancer, it is likely that nuts have a preventive effect against colonic cancer, rectal cancer and prostatic cancer. More research is necessary to pinpoint the exact role of peanuts and nuts in preventing cancer.
