Lifestyle diseases such as cancer, heart disease, cerebrovascular disease, are the three leading causes of death among the Japanese, and the prevention of lifestyle diseases is an important issue in Japan. Daily high energy intake and high fat diet are involved in the onset of lifestyle diseases, and nutritional therapy is important for the prevention of lifestyle diseases. Nutritional therapy for lifestyle diseases is based on scientific data which is important to be established. The authors found that lipid nutrition for insulin resistance and non-alcoholic fatty liver disease (NAFLD) from the association of physical measurement, clinical data, nutrient intake and plasma fatty acid composition. As a result, it was suggested that the low levels of n-3 Polyunsaturated Fatty Acids (n-3 PUFA) in plasma phospholipid may be related to insulin resistance, and the decrease in n-3 PUFA intake was also involved in the rise in n-6/n-3 ratio. It was also suggested that increasing NAFLD Score not only reduces energy intake, but also increases fish and n-3 PUFA intakes. The clarification that n-3 PUFA intakes of eicosapentaenoic acid and docosahexaenoic acid is involved in the prevention and improvement of lifestyle related diseases in elucidating the nutritional therapy of lipids in lifestyle related diseases has revealed the importance of lipid nutrition in lifestyle related diseases. It is thought that it contributes to the establishment of nutritional therapy of lipid.

The Japan Atherosclerosis Society Guidelines for the Prevention of Atherosclerotic Cardiovascular Diseases (JASGL) were based on “the lower, the better” hypothesis. However, we published Cholesterol Guidelines for Longevity 2010 based on the fact that cholesterol levels are inversely associated with all-cause mortality among general populations aged at 40 years and over. Here, we summarized the mechanisms of atherogenesis caused by statins and some types of vegetable oils with strokestimulating activity in the rat; they inhibit the VK1-VK2- osteocalcin target organs link, leading to artery calcification and lifestyle-related diseases. The mainstay of JASGL 2017 is the Suita study published in 2014, which is much smaller than the previous epidemiological study, NIPPONDATA 80, for JASGL 2012. Besides, the total and cardiovascular mortality of the study has not been published yet. We found some terrible mathematical errors that cannot be simple calculation mistakes. For example, deleting some study subjects actually increased the number of male participants instead. It is likely that no consistent epidemiological studies are available any more to JAS to protect their cholesterol hypothesis. JASGL 2017 calculated risk of coronary artery disease (CAD) in Japan where the incidence is very low. Then the story was fabricated to protect their notion that even the group with a very low risk in the world standard was classified as middle to high risk groups of CAD, which can lead to unnecessary medication. The GLs are disguised as those based on the cholesterol hypothesis; actually it became very clear that they are simply selling tools for statins.

White adipose tissue configures body fat, while brown adipose tissue (brown fat: BAT) is the only cell in the human body engaged in specialized in heat production. Loss and depression of BAT, which actively consume fat (triacylglyceride), have been shown to cause lifestyle-related diseases such as obesity and diabetes associated with it. Food and nutrition ingredients play a dominant role in BAT thermogenesis and energy metabolism. Especially, some ingredients activate BAT via the transient receptor potential-sympathetic nervous system. These results are expected to apply on anti-obesity treatment. This article reviews the major advances in the field of diet-induced thermogenesis and food ingredients.

Previous cholesterol guidelines for the prevention of CHD were based on "the lower, the better" hypothesis, setting upper LDL-C limits and treating patients to maintain their cholesterol levels below the targets, as seen in the ATP 3 issued from the National Heart, Lung, and Blood Institute (NHLBI) and that issued from the Japan Atherosclerosis Society (JAS GL). We published a new cholesterol guideline for longevity (JSLN GL 2010), in which evidence was presented that a high cholesterol level is not a causative factor of CHD but is a predictor of longevity among general populations over 40-50 years of age. Recently, a long-waited revision of the ATP 3 was published from the NHLBI in conjunction with the American College of Cardiology and the American Heart Association (ACC/AHA GL 2013), in which "setting targets to treating patients with statins" and "the lower, the better hypothesis" were abandoned because of the lack of clinical evidence. However, both the JAS GL 2012 and ACC/AHA GL 2013 brought about estimated 10-year CHD (ASCVD) risk mainly based on NIPPON DATA 80 and NHLBI-supported studies, respectively, resulting in increased estimated number of subjects to be treated with statins. Here, we point out that the estimated 10-year risks are not usable because they are not evidence-based. Moreover, we summarize biochemical mechanisms underlying the statin actions to increase heart failure, diabetes mellitus and other diseases after long-term treatments. The cases for which statins, all mitochondrion-toxic, are applicable should be extremely restricted.

日本人の脂肪摂取の長期間の推移を知るために,1952年から1995年度までの44年間の国民栄養調査成績から脂肪酸摂取量や脂肪酸摂取比率を算出した。その結果,次のような知見が得られた。1 44年間で脂肪摂取量は3倍に,総脂肪酸摂取量は3.1倍に増加した。2動物性脂肪:植物性脂肪:魚類由来脂肪は,1952年は0.6:3.7:1であり,1995年には4.1:5.4:1で,摂取比率では動物性脂肪が増加し植物性脂肪は減少した。3飽和脂肪酸:一価不飽和脂肪酸:多価不飽和脂肪酸は1952年の1:1:1.5から1995年には1:1.1:1と変化した。4 44年間で飽和脂肪酸は3.5倍,一価不飽和脂肪酸は3.9倍,多価不飽和脂肪酸は2.2倍の増加で,飽和や一価不飽和脂肪酸の増加は肉類摂取の影響が大きかった。5 n-6/n-3,リノール酸/α-リノレン酸は1952年ではそれぞれ4.1,8.6で,1995年では4.7,8.8であった。6総脂肪酸量に占めるリノール酸やα-リノレン酸の割合は,1995年では1952年よりも減少していた。7 n-6系多価不飽和脂肪酸の供給源は油脂類,n-3系多価不飽和脂肪酸の供給源は魚類が1位であった。8摂取する油脂類として,植物油を各種に置換してn-6/n-3を算出すると,n-3系多価不飽和脂肪酸,特にα-リノレン酸の多い植物油ではn-6/n-3は低下した。

Rats fed n-3 fatty acid deficient diet through two generations exhibit decreased correct response ratios in a brightness-discrimination learning test. This is associated with a decreased docosahexaenoic acid (DHA) to arachidonic acid (AA) ratio in brain lipids. The altered learning behavior associated with a long-term n-3 deficiency was reversed by supplementing DHA after weaning only when the levels of competing n-6 fatty acids in the diet and brain lipids are limited. Endocannabinoid 2-arachidonoylglycerol (2-AG) levels were significantly elevated in the brain of n-3 deficient rats. We evaluated the effect of cannabinoid receptor CB1 antagonist SR141716A (SR) on the learning behavior. SR did not ameliorate the decreased learning performance in the n-3 deficient rats. However, the increased locomotor activity by n-3 deficiency was suppressed by SR. Therefore, the altered behavior is associated with, at least in part, the endocannabinoid signaling. We also found the decreased nerve growth factor (NGF) content and the increased level of the activated form of calmodulin kinase II in the hippocampus of n-3 deficient rats. DHA has an essential role in biomembrane structure and functions, which affect the cellular signaling related to learning behavior.

In order to know how to live longer and healthy, we conducted centenarian study with multidisciplinary approach since 2000. We presented here the results of our study. The characteristics of centenarians are 1) low prevalence of diadetes mellitus, 2) frequency of illness is 97%,3) prevalence of dementia free and independent centenarian is 18%, 4)low level of albumin, 5) low-grade activation of inflammation, 6) high level of adiponectin. We proposed aging-inflammation hypothesis. Since centenarian is not the model of healthy longevity, we began to study semisupercentenarians (SSC). SSC are considered to be a real model of human longevity. Whole genome scan of both SSC and control group, is now in progress. We hope that longevity genes will identified within a few years.
