Seaweeds Are High-Nutrient Foods

Posted Jun 29 2013 10:08pm

Seaweeds or marine algae are rich in vitamins – such as Vitamin C, minerals – including potassium, and nutrients that are important for most of the body’s  biochemical reactions.   Researchers from Alagappa University,  (India) report that Gelidiella acerosa (red seaweed) and Sargassum wightii (brown seaweed) are also abundant sources of amino acids valine, methionine, and lysine; as well as the fatty acid linoleic acid. The study authors submit that: "The results suggest that both the seaweeds have greater nutritional value and could be used as excellent nutritional supplements.”

Tip #182 - Think Zinc
Harvard School of Public Health (Massachusetts, USA) researchers investigated the intake of zinc in relation to risk of type-2 diabetes in American women. The team assessed data collected on participants in the Nurses’ Health Study, comprised of 82,297 women, ages 33 to 60 years at the study’s start. The researchers found that those women with the highest average daily intake of zinc were 10% less likely to develop type-2 diabetes. Further, those women with the highest average total intakes slashed their risk by 8%. Perhaps most importantly, the researchers showed that an increased intake of zinc was associated with a 28% reduction in type-2 diabetes.

Zinc is a plentiful trace element in the body, and it mediates many physiological functions. The US guidelines recommend that women ages 19-50 years consume 8 mg of zinc daily; men ages 19-50 years, 11 mg. Shiitake and crimini mushrooms, spinach, and pumpkin seeds are foods rich in zinc.
