Sending caring thoughts to the growing interest in accurate nutrition information by subscribers to nutritioninvestigator. Read the summaries with links to abstracts at www.nutritioninvestigator.org. Here’s the headlines:

EAT LESS RED MEAT! GET ENOUGH VITAMIN D and FISH OIL.1. Consumption of red meat causes health hazards– [choose the no fours diet]. 2. Get lycopene to preserve your liver. 3. Up to 17% of obese in US are vitamin D deficient with numerous health hazards. – Vitamin D may play a role in depression, autoimmune disease, metabolic syndrome, cardiovascular disease, diabetes mellitus, hypertension, infectious diseases, and cancer. [Most need 2,000IU daily via a supplement.]

4. 10% of vitamin supplement users exceeded safe intakes (UL) for vitamins A and C, niacin, folic acid, iron, zinc, and magnesium. 5. Tocotrienols, available from a healthy diet but not in vitamin E supplements, are also essential. – The natural vitamin E family is composed of 8 members equally divided into 2 classes: tocopherols (TCP) and tocotrienols (TE). 6. Inuit communities suffer food insecurity and diet-related chronic disease. The same is true for most disadvantaged in industrialized and third-world nations. 7. Vitamin supplementation should begin as early as possible in pregnancy. 8. EGCG (green tea) reduces autoimmune and inflammatory disorders.

9. Symposium on getting long chain omega-3 fatty acids to everyone for health benefits. Dietary fatty acids (FA) are increasingly recognized as major biologic regulators and have properties that relate to health outcomes and disease. EPA and DHA possess distinct physical and biological properties that generally impart properties to cells and tissue, which underlie their ability to promote health and prevent disease.

SYNOPSES OF THE JOURNAL of NUTRITION ARTICLES THIS MONTH

1. Consumption of red meat causes health hazards– [choose the no fours diet]. Data provided little support for the associations between specific micronutrients and Metabolic syndrome (MetS), Type 2 diabetes (T2D), and cardiovascular disease (CVD). However, nutrients consumed in red meat, or red meat as a whole, may increase risk of MetS and CVD.

2. Get lycopene to preserve your liver. – Lycopene has been shown to be beneficial in protecting against high-fat diet-induced fatty liver.

3. Up to 17% of obese in US are vitamin D deficient with numerous health hazards. – So are about 10% of others. Recently, there has been considerable interest in the possibility of an expanded role for vitamin D in various infirmities such as depression (9), autoimmune disease (10), metabolic syndrome (11, 12), cardiovascular disease (13–15), diabetes mellitus (16), hypertension (17, 18), infectious diseases (19, 20), and cancer (21, 22).

4. 10% of vitamin supplement users exceeded safe intakes (UL) for vitamins A and C, niacin, folic acid, iron, zinc, and magnesium. In conclusion, from diet alone, the prevalence of nutrient adequacy was low for most nutrients except for calcium, magnesium, and vitamins A and D.

5. Tocotrienols, available from a healthy diet but not in vitamin E supplements, are also essential. – The natural vitamin E family is composed of 8 members equally divided into 2 classes: tocopherols (TCP) and tocotrienols (TE). A growing body of evidence suggests TE possess potent biological activity not shared by TCP. This work provides, to our knowledge, the first evidence demonstrating that orally supplemented TE are transported to vital organs of adult humans.

6. Inuit communities suffer food insecurity and diet-related chronic disease. The same is true for most disadvantaged in industrialized and third-world nations.\

7. Supplementation should begin as early as possible in pregnancy. In conclusion, for both IFA and UNIMMAP, the effect on fetal growth is cumulative. The supplementation should therefore begin as early as possible in pregnancy, even if the growth increment per CMI is higher in late than in early pregnancy. Women with a low BMI should also receive extra energy.

8. EGCG (green tea) reduces autoimmune and inflammatory disorders. This implies a potential application in controlling dysregulated T cell functions such as those observed in autoimmune and inflammatory disorders.

9. Symposium on getting long chain omega-3 fatty acids to everyone for health benefits. Dietary fatty acids (FA) are increasingly recognized as major biologic regulators and have properties that relate to health outcomes and disease. The longer chain, more bioactive (n-6) (or omega-6) FA and (n-3) (or omega-3) FA share similar elongation and desaturation enzymes. Conversion from these essential FA is very inefficient. EPA and the longer chain DHA possess distinct physical and biological properties that generally impart properties to cells and tissue, which underlie their ability to promote health and prevent disease.
