Mitochondrial DNA inherited from both parents!


Paper: "Biparental Inheritance of Mitochondrial DNA in Humans", by
Shiyu Luo, et al., PNAS, November 26, 2018


The energy-producing organelle mitochondrion contains its own compact genome, which is separate from the nuclear genome. In nearly all mammals, this mitochondrial genome is inherited exclusively from the mother, and transmission of paternal mitochondria or mitochondrial DNA (mtDNA) has not been convincingly demonstrated in humans. In this paper, we have uncovered multiple instances of biparental inheritance of mtDNA spanning three unrelated multiple generation families, a result confirmed by independent sequencing across multiple unrelated laboratories with different methodologies. Surprisingly, this pattern of inheritance appears to be determined in an autosomal dominantlike manner. This paper profoundly alters a widespread belief about mitochondrial inheritance and potentially opens a novel field in mitochondrial medicine.

To reduce nitrates eat less vegetables

5 times more dietary nitrates come from vegetables than from cured meats!

Not as bad ...  (Wiki - Saussage)

Not as healthy ...(Wiki Healthy_diet)
"Contribution of vegetables and cured meat to dietary nitrate and nitrite intake in Italian population: Safe level for cured meat and controversial role of vegetables"
Rossana Roila et al., Italian Journal of Food Safety, Vol 7, No 3 (2018)


Table 1 from the quoted paper.

The paper found that most nitrates in an average diet studied, come from vegetables not cured meats!

The average consumption among population resulted 3.45 g/kg bw/die [gram per kg body per daily dietary intake] and 0.62 g/kg bw/die for vegetables and cured meat respectively. The obtained data confirm that nitrate ADI was higher than the limits of 3.7 mg/kg bw/die for infants and was the highest exposure level for people of all ages. Cured meat consumption did not contribute to nitrate ADI exceedance neither as a mean nor as 99th percentile of exposure.

Mediterranean diet is good, adding meat & dairy makes it better!

as the following two studies have recently demonstrated:

1) "A Mediterranean-style eating pattern with lean, unprocessed red meat has cardiometabolic benefits for adults who are overweight or obese in a randomized, crossover, controlled feeding trial",
Lauren E O'Connor, Douglas Paddon-Jones, Amy J Wright, Wayne W Campbell,
The American Journal of Clinical Nutrition, Volume 108, Issue 1, 1 July 2018, Pages 33–40

Note: they used lean read meat. I predict a follow-up study titled "A Mediterranean-style eating pattern with fatty, unprocessed red meat has the greatest cardiometabolic benefits"!

2) "A Mediterranean diet supplemented with dairy foods improves markers of cardiovascular risk: results from the MedDairy randomized controlled trial",

Compared with the LF intervention, the MedDairy intervention resulted in a significantly lower morning SBP (mean difference: −1.6 mm Hg; 95% CI: −2.8, −0.4 mm Hg; P = 0.01), lower morning diastolic blood pressure (mean difference: −1.0; 95% CI: −1.7, −0.2 mm Hg; P = 0.01) and clinic SBP (mean difference: −3.5 mm Hg; 95% CI: −6.4, −0.7 mm Hg; P = 0.02), significantly higher HDL cholesterol (mean difference: 0.04 mmol/L; 95% CI: 0.01, 0.06 mmol/L; P < 0.01), lower triglycerides (mean difference: = −0.05 mmol/L; 95% CI: −0.08, −0.01 mmol/L; P < 0.01), and lower ratio of total to HDL cholesterol (mean difference: −0.4; 95% CI: −0.6, −0.2; P < 0.001). No effects were observed for other outcome measures. Conclusions
Following a MedDiet with additional dairy foods led to significant changes in markers of cardiovascular risk over 8 wk. The MedDiet supplemented with dairy may be appropriate for an improvement in cardiovascular risk factors in a population at risk of CVD.
