健康饮食关系寿命长短
一项新调查显示,饮食问题造成全球每年1100万人早亡。
这份发表在《柳叶刀》上的研究发现,日常饮食是人类健康的最大杀手,比吸烟还厉害。全球五分之一人的死亡是跟饮食不健康有关。
食盐
其中,食盐过量是造成人们减寿的最大原因。面包、酱油以及加工食品中都有许多盐。
科研人员说,该研究主要针对“非健康”饮食对心脏所造成的伤害以及诱发癌症,而不是肥胖问题。
炸鱼和薯条
全球疾病负担研究(The Global Burden of Disease Study)发表了关于全球各国死因的权威性评估报告。
该报告的最新分析,是利用对各国饮食习惯的评估来判断多少早亡是否与饮食有关。
这些危险饮食包括:吃盐过多造成全球每年300万人死亡。食用全谷类食品过少同样导致300万人死亡。吃水果过少则导致200万人死亡。
此外,坚果类、植物种子、蔬菜、富含欧米伽-3的海产品以及纤维等吃的不足也是造成人们早亡的主要原因。
死因
心血管疾病是跟饮食有关的最主要死因,这就解释了为什么盐是最大问题。
因为食盐过多会导致血压增高,从而增加心脏病和中风的危险。
盐可以对心脏和血管产生直接影响,导致心脏衰竭等。
而多吃全谷类食品、水果和蔬菜则对心脏有好处。它们可以起到保护心脏的作用,并降低心脏病风险。
除心血管疾病以外,癌症和二型糖尿病也是与饮食有关的另外两大死因。
坚果和植物种子?
根据该研究,在全世界各国人们膳食中吃得最少的健康食品就是坚果和植物种子。
既然坚果和植物种子这么健康,那为什么我们不多吃点呢?
英国剑桥大学的尼塔·福罗希教授(Nita Forouhi)表示,这可能跟人们认为这些食品能量高,容易引起人发胖有关。
“而且,大多数人并不认为它们是主流食品。另外,还有成本问题,”福罗希教授说。
近年来,人们一提非健康食品就会想到脂肪、糖等。同时,还有红肉和加工肉与癌症之间的联系。
但是专家表示,虽然以上食品摄入过多的确对人体有害,但与进食全谷类、水果、坚果、植物种子和蔬菜过少相比,危害还算轻的。
人们饮食中普遍缺少坚果类
因此,研究人员说,现在是该从谈糖和脂肪等不健康食品转向呼吁人们多吃健康食品的时候了。
研究人员说,从全世界范围来看饮食不佳可以导致人的预期寿命减少两年。
美国华盛顿大学健康指标评估研究所的主任莫里教授敦促人们自问一下:“我会不会在50多岁就死于突发心脏病?或是由于饮食关系在40多岁患癌症?”
那么,哪些国家在这方面做得相对好一些?
地中海国家,西班牙和以色列是全球范围内由于非健康饮食致死的人数最低的国家。
但东南亚、南亚以及中亚则正好相反。
在以色列,与饮食有关的死亡人数是最低的,每10万人有89个。
但在乌兹别克斯坦,每10万人中就有892人由于不健康饮食而死亡。
中国
中国是食盐大国。中国人做菜一般少不了酱油以及其它含盐量较高的调料。
而随着加工食品的日益普及,人们从饮食中摄取的盐量有增无减。因此,中国也是所有国家中由于食盐量过多导致死亡人数最高的国家。
莫里教授表示,中国人目前的盐摄取水平有点像30、40年前的日本。虽然,吃盐过多仍然是今天日本所面临的第一大问题,但日本人食盐量已经大幅减少。
中国食品和调料中含盐较高
另外,日本人饮食中含有许多对心脏具有保护作用的成分:例如蔬菜和水果。
在健康饮食摄取方面,西欧当中法国、丹麦和比利时都排在英国前面。
英国饮食最大的问题是缺少全谷类、蔬菜、水果、坚果和植物种子类。
研究称,估计英国14%的死亡与饮食有关。 英国每年与饮食有关所导致的死亡人数为每10万人中有127人。
建议
莫里教授说,“无论你的体重如何,饮食质量很关键。”
他的建议是:多吃全谷类、水果和蔬菜、坚果及植物种子类食品,同时尽量减少食盐。
当然,在比较贫穷的国家,每天能保证五份水果和蔬菜会占据家庭收入的52%。因此,这里还有钱的问题。
但福罗希教授警告道,如果公众知情并有能力会做出更加健康的选择,而商店货架上则到处是买一送一的不健康食品呢?那健康饮食的建议就会失灵。
“人们急需的是物美价廉的健康食品选择,”福罗希教授说。
两位教授一致认为,人们需要转移重心:即从关注营养成分(脂肪/糖/盐)问题转到吃什么食物才健康。
文章翻译自英国BBC网
In your daily diet, aim to eat a mix of staple foods such as wheat, maize, rice and potatoes with legumes like lentils and beans, plenty of fresh fruit and veg, and foods from animal sources (e.g. meat, fish, eggs and milk).
Choose wholegrain foods like unprocessed maize, millet, oats, wheat and brown rice when you can; they are rich in valuable fibre and can help you feel full for longer.
For snacks, choose raw vegetables, unsalted nuts and fresh fruit, rather than foods that are high in sugars, fats or salt.
When cooking and preparing foods, use salt sparingly and reduce use of salty sauces and condiments (like soy sauce, stock or fish sauce).
Avoid snacks that are high in salt, and try and choose fresh healthy snacks over processed foods.
When using canned or dried vegetables, nuts and fruit, choose varieties without added salt and sugars.
Remove salt and salty condiments from the table and try and avoid adding them out of habit; our tastebuds can quickly adjust and once they do, you are likely to enjoy food with less salt, but more flavor!
Check the labels on food and go for products with lower sodium content.
We all need some fat in our diet, but eating too much – especially the wrong kinds - increases risks of obesity, heart disease and stroke. Industrially-produced trans fats are the most hazardous for health. A diet high in this kind of fat has been found to raise risk of heart disease by nearly 30%.
Replace butter, lard and ghee with healthier oils such as soybean, canola (rapeseed), corn, safflower and sunflower.
Choose white meat like poultry and fish which are generally lower in fats than red meat, trim meat of visible fat and limit the consumption of processed meats.
Try steaming or boiling instead of frying food when cooking.
Check labels and always avoid all processed, fast and fried foods that contain industrially-produced trans fat. It is often found in margarine and ghee, as well as pre-packaged snacks, fast, baked and fried foods.
Too much sugar is not only bad for our teeth, but increases the risk of unhealthy weight gain and obesity, which can lead to serious, chronic health problems.
As with salt, it’s important to take note of the amount of “hidden” sugars that can be in processed food and drinks. For example, a single can of soda can contain up to 10 teaspoons of added sugar!
Some tips to reduce sugar intake:
Limit intake of sweets and sugary drinks such as fizzy drinks, fruit juices and juice drinks, liquid and powder concentrates, flavoured water, energy and sports drinks, ready-to-drink tea and coffee and flavoured milk drinks.
Choose healthy fresh snacks rather than processed foods.
Avoid giving sugary foods to children. Salt and sugars should not be added to complementary foods give to children under 2 years of age, and should be limited beyond that age.
Alcohol is not a part of a healthy diet, but in many cultures New Year’s celebrations are associated with heavy alcohol consumption. Overall, drinking too much, or too often, increases your immediate risk of injury, as well as causing longer-term effects like liver damage, cancer, heart disease and mental illness.
WHO advises that there is no safe level of alcohol consumption; and for many people even low levels of alcohol use can still be associated with significant health risks .
Remember, less alcohol consumption is always better for health and it is perfectly OK not to drink.
You should not drink alcohol at all if you are: pregnant or breastfeeding; driving, operating machinery or undertaking other activities that involve related risks; you have health problems which may be made worse by alcohol; you are taking medicines which directly interact with alcohol; or you have difficulties with controlling your drinking.
If you think your or someone you love may have problems with alcohol or other psychoactive substances, don’t be afraid to reach out for help from your health worker or a specialist drug and alcohol service. WHO has also developed a self-help guide to provide guidance to people looking to cut back or stop use.

The trendy superfood ‘red dates’ from Asia kill cancer cells in the lab, new research suggests.
Jujube fruits, which are known as red dates due to them looking similar to the Middle-Eastern staple, programme lung, breast and prostate cancer cells to commit suicide, a study published in the journal Food & Function found.
Red dates are thought to trigger cancer cell death by causing 'internal stress' in tumours, according to researchers from the Royal Society of Chemistry.
The results occurred after cancer cells were exposed to jujube in the lab. It is therefore unclear if the fruit helps to prevent or treat the disease in humans.
Jujube fruits, which are used in Chinese medicine to treat insomnia, a loss of appetite and diarrhoea, are available in the UK for just £1.99 for a 40g bag.
The researchers exposed human lung, breast and prostate cancer cells to eight compounds found in jujube fruits.
Results suggest four of the compounds reduce the survival rate of these cells.
In addition, three red-date compounds trigger cancerous cells to kill themselves.
Internal stress caused by the compounds is thought to damage tumours' structures.
The researchers believe jujube extracts could be used in cancer treatments in traditional Chinese medicine.
They add, however, further research is required to determine how jujube fruit's compounds trigger cancer cell death.
What are red dates?
Although jujube fruits look like dates, they are believed to contain 32 times more vitamin C, as well as being higher in antioxidants, than the sticky Middle-Eastern treat.
A portion of three dates contains 54 calories and 12g on sugar, on average, while the same amount of jujube has just 28 calories and 6g of sugar.
Jujube fruits also contain 18 out of the 24 amino acids that help with the formation of proteins in the body.
Helen Wang, founder of Abakus Foods, previously told MailOnline: 'The Chinese saying goes "three jujube berries a day, keeps you young forever".
'It's not easy to find something that tastes good and is good for you at the same time.'
Blackcurrant supplement can burn as much fat as four weeks of exercise
This comes after research released last May suggested a blackcurrant-extract supplement can burn as much fat as four weeks of regular exercise.
When taken twice a day for just one week, the vitamin increases fat burning by an average of 27 per cent, with one study participant achieving a rise of 55 per cent.
Known as CurraNZ, the supplement is made from New Zealand blackcurrants and costs £21.75 for a pack of 30.
The berries contain nutrients, called polyphenols, which are thought to encourage fat burning during exercise by increasing blood flow, according to the researchers.
Study author Dr Sam Shepherd, from Liverpool John Moores University, said: 'Seven days is not a very long time to see such big changes.
'Anything above 20 per cent is typically what we expect to see with three-to-four weeks of regular endurance exercise training.'
Nearly 80 percent of hair products aimed at black women contain chemicals linked to cancer, infertility and obesity, research suggested in April 2018.
Up to 78 percent of relaxers, which are used to permanently straighten hair, contain hormone-disrupting chemicals, known as parabens, a study by the Silent Spring Institute, Massachusetts, found.
Past studies suggest parabens, which are used as preservatives, mimic oestrogen and may cause cancer, weight gain and reduced muscle mass.
Up to 78 percent of hair products, including leave-in conditioners, also contain phthalates, the research adds.
Phthalates are added to prolong products' shelf lives and have been linked to breast and ovarian cancer, as well as early menopause.
Out of the 18 products analysed, 11 contain chemicals that are banned under the EU cosmetic regulations due to their links to cancer and female infertility.
Previous research suggests black women are more likely to use straightening and moisturising hair products to try and meet social beauty norms.
Results further suggest that hair products aimed at black women contain up to 45 hormone-disrupting chemicals, which are not generally listed on their labels.
All of the products contain at least one fragrance, which have previously been described as 'gender benders' due to them encouraging male-breast growth.
The worst offenders were found in hair lotions, root stimulators and relaxers.
Lotions claim to moisturise, while root stimulators are thought to encourage hair growth and strength.
Since we are on subject of the plant-based something, I might as well elaborate a little bit on the plant-based milk since we had already touched upon plant-based hamburger last time.
I spent 17 years of my career using soy protein isolates in the development and formulation of protein-containing neutral and acidic beverages including powdered dry blended and liquid ready to drink versions. Of the name brand touched are Amway, Herbalife, Ensure, Slim Fast, Carnation Instant Breakfast, Boost, Bolthouse, Odawalla, V8 and Naked Juices, etc. In them, soy protein isolates are used to replace dairy protein for economic reason. Let’s leave out technicality but just focus on the definition of “milk”. Cow’s milk is the gold standard On a per 8 oz. or 240 ml. serving basis, it needs to contain at least 8 g of protein or it can only be called drinks. Furthermore, milk is high in calcium content as well as rich in vitamin A, therefore, for a plant-based milk to claim for milk nutrition in plant-based milk, fortification is necessary other than meeting the protein requirement
These have been the rules strongly lobbied by the dairy industry as well as enforced by both FDA and USDA. However, time seems to have changed recently because of the trendy demands for plant-based products, the regulatory agency like FDA has loosened up the definition. Therefore, we saw in the news that Just Mayo egg-free mayonnaise by Hampton Creek had won the legal battle against the famous Hellmann’s brand by Unilever. However, the French food regulation had just forbidden all the non-meat products to use the meat name like hamburger, meat ball and/or meat pie, etc. Interesting!
As a wise consumer, I just want you to shop wisely. Shop for your health and nutrition but also shop for your hard-earned money making sure the products you buy is well worth the money you spent.
On the market places now we can see commercial coconut milk, pea protein milk, soy milk, rice milk, cashew milk, almond milk and may be soon peanut milk. I did some shopping around and want to share with you their nutrition labelling. Using the name brand Silk for example, their soy milks contain between 6-7g per serving of 8oz. For their coconut milk, the protein claim is 0g/8oz, for almond milk 1g/8oz and cashew milk<1g/8oz. However, they do have other version claimed with high protein milk and fortified with pea protein.
If we have some Chinese readers here asking about your famous brand of “6 Walnuts”, I did some homework there, too. By calculation based on its nutritional labeling of 0.6g protein/100 ml, it contains about 2 walnuts but not 6! They have about 1.44g/240 ml of protein, not much better than either almond or cashew milk here in the States. So, be wise when you shop for plant-based milk!
Last month we discussed about the trendy human nutrition topics. Among them, protein appeared to be one of the most important and hot item in different areas of human nutrition such as sport nutrition, weight management, and health & wellness. This month we are to focus on the plant-based proteins.
According to Lux Research, plant-based protein could represent one-third of overall protein by 2054. Introduction of new products with plant-based proteins grew 14.7% in 2014 as compared to that of animal protein at 7.5% by Innova Market Insights. U.S. sales of plant-based proteins were $553 million in 2012, according to Mintel. The global plant-based protein market is projected to reach to $5 billion by 2020 as reported by Markets and Markets. The plant-based food sector experienced overall growth of 8.1% since 2017 as compared to a decline of 0.2% of all foods sold in the same channel, according to Nielsen.
The plant-based milk category has grown 3.1% last year while cow’s milk sales experienced decrease of 5% as by Nielsen. U.S. sales of almond milk topped $1 billion in 2014 as reported by Packaged Facts. Globally, dairy alternatives market is predicted to be worth $19.5 billion by 2020.
Consumers want plant-based products. About 36% of consumers buy plant-based meats and 60% of the millennials consume plant-based meats according to a survey conducted by 210 Analytics. About 26% of consumers reported eating less animal meat in the past 12 months according to Nutrition Business Journal. Nowadays about 36% of consumers prefer plant-based milks.
Most importantly, plant-based is better for the environment. Producing plant-based meat alternatives generates 10X less greenhouse gas emissions than producing similar beef-based products. Producing 1 Kg of kidney bean protein requires 18X less land, 10X less water, 9X less fuel, 12X less fertilizer and 10X less pesticides than producing 1 Kg of beef protein, according to study by Sabate et al. Plant-based eaters contribute approximately half as much dietary greenhouse gases as meat-eaters. It takes 10g of vegetable protein to create every 1g of animal protein according to a study by Reijnders et al.
If beans replaced beef in the US diet, the US could meet up to 75% of its 2020 greenhouse gas reduction target as reported by Helen Harwatt et. Al. Substituting beans for beef in the US diet would free up 42% of US cropland or 400 million square acres, or 1.6 times the size of California.
When the meatpacking giant Cargill sold off its last cattle feedlots in April 2017, it said that it wanted to free up funds to invest in alternatives like insects and plant-based protein. Four months later, along with Bill Gates and Richard Branson, the company joined a $17 million round of investment in Memphis Meats, a startup that grows beef and chicken from cells instead of farms. Tyson Foods, the largest meat producer in the U.S., was part of a $55 million round of investment in Beyond Meat. Nestle acquired Sweet Earth Foods, which sells products like “Harmless Ham” and “Benevolent Bacon”. Maple Leaf Foods strong in the meat product categories acquired Lightlife, a company that makes products like “Chick’n” and plant-based hot dogs.
Newer companies in the industry, such as Impossible Foods and Memphis Meats, aren’t targeting vegetarians with their products; instead, their burgers are designed to appeal to meat eaters who are concerned about issues like the carbon footprint of beef, or the overuse of antibiotics on farms. Companies like Morning Star Farm that have been around longer, making veggie burgers for a niche market, are also realizing that their products can evolve. Technology is making meatless meat truly realistic and will continue to improve.
When Impossible Burgers are compared against Beyond Burgers side by side, a reporter testified both were extremely good and couldn’t tell them from the regular burgers. I tried to buy the Beyond Burgers from Wegman’s and cooked them at home and served them to my family members of four. Everybody liked the burgers. Beyond Meats distributed in 19,000 retail stores while Impossible Burgers are sold in burger outlets like TGIF’s. It just got another round of investment total up to $40 million.
As for plant based milks, almost all the major beverage brands are having their products on the shelf. There are coconut milk, peanut milk, soy milk, pea milk, cashew milk, walnut milk and almond milk, etc. During my time in the soy milk industry, the milk industry lobbied that the standard identity of milk is sacred and the other protein beverages to be called milk should meet the nutritional profile of milk before they can be called milk or they should be called milk drinks. The Just Mayo court battle is well known between Unilever’s Hellman’s Mayonnaise and Hampton Creek Foods. FDA seemed to loosen up the standard of identity quite a bit. For consumer buying plant-based milk, I urge you read the nutritional labels. Usually, I won’t buy almond, walnut, coconut or cashew milk, their proteins are extremely low per serving of 8 oz. as compared to true milk.
Talk to you next month!

来自加利福尼亚和法国的研究人员进行的一项研究发现,蛋白质会使患心脏疾病风险急剧增加,而来自坚果和植物的蛋白质对人体心脏是有益的。
研究的标题为“植物和动物蛋白质摄入模式与心血管死亡率密切相关:基督复临健康研究-2队列”,这项研究由加利福尼亚罗马琳达大学公共卫生学院、巴黎高科农业学院和法国巴黎国家研究所的联合进行。这项研究在线发表于《国际流行病学杂志》,研究发现,摄入大量肉类蛋白质的人患心血管疾病(CVD)的风险增加了60%,而从坚果和植物中摄入大量蛋白质的人患心血管疾病的风险减少了40%。
这项研究包括了来自81000多名参与者的数据,是主流调查中少数几次将动物蛋白的详细来源与动物脂肪联合检查的研究之一。
来自罗马琳达大学的Gary Fraser博士和来自巴黎高科农业学院和国家农艺研究所的FrançoisMariotti博士担任联合首席研究员。Fraser 说:“虽然膳食脂肪是对患心血管疾病的风险产生影响的因素之一,但蛋白质也可能对这种风险有很重要影响,这种影响是独立的,却会在很大程度上被忽略。”他还说,他和他同事一直怀疑坚果和植物能保护心脏,而红肉有使人患心脏病的危险。
Fraser补充说,被他称为肉类中的“有害脂肪”和坚果和植物中的“有益脂肪”一直被营养学家所,并称之为致病因子。然而,这些新发现说明了更多的东西。他说:“这一新的证据表明,在完整的环境下,也可能掺杂有这些食物中蛋白质的生物学效应。”
Fraser说,该小组的研究与先前的调查不同。虽然先前的研究已经对动物和植物蛋白之间的差异进行了检验,但这项研究并没有停留在这两个类别上,而是选择从其他主要的膳食来源中,在坚果和植物中区别肉类蛋白质和其他蛋白质蛋白质。Fraser说“这项研究表明,植物蛋白或动物蛋白的二元分类外,还存在者更多的异质性。”
Fraser说,在这项研究中还有其他问题有待进一步研究,例如肉蛋白中特定的导致心血管疾病的氨基酸。另一个问题是来自特定来源的蛋白质是否会导致患心血管疾病的风险因素,如血脂、血压和超重,这些因素都与心血管疾病相关。

介绍
我们每个人都想健康、活泼、长寿。这没什么不对。然而,为了正确对待自己的身体,我们需要学习一些关于人类营养学的基本知识。孕妇、哺乳期母亲、成长期青少年、运动员和老年人需要特定的营养。我们对营养问题进行普通讨论。对于那些对特定营养感兴趣的人士,我建议您咨询持证营养师。
宏观和微观营养素
在研究营养物质时,我们将其分为宏观和微观两种营养素。在今天的讨论中,我们只涉及宏观营养素,即蛋白质、碳水化合物包括膳食纤维和脂质。
蛋白质
通常,WHO建议使用PDCAAS(蛋白质消化校正的氨基酸评分),并在将来使用DIAAS(可消化的必需氨基酸评分)来标识蛋白质的质量。两者的完美得分是1分。参考蛋白一般为蛋清或酪蛋白。就我所知,没有植物蛋白被用作参考蛋白。普遍原因可能是,优质蛋白质更有可能来自于动物而不是植物蛋白!
在谈论到蛋白质时,过敏原是一个经常被提及的敏感词。鸡蛋、牛奶、大豆、花生和小麦麸质具有较高的致敏性,而大米和豌豆则被认为具有较低的致敏性。这就是为什么现在市场上有正在推广很多无麸质产品。而来源于豌豆蛋白质的植物奶现在变得非常流行。
蛋白质是肌肉合成及修复、结缔组织和内脏器官生长及修复所需要的,也是消化功能和其他重要生理功能(如能量生产)不可或缺的酶的重要来源。
过剩的的膳食蛋白质并不会被储存,而是通过肾脏排出体外。
你可能会问每天应该摄入多少蛋白质。真是个好问题!各个年龄段所需要摄入的蛋白质确实是不一样的。正在发育的青少年、怀孕的女士、出于哺乳期的妈妈、病人、生病刚刚康复的人以及老人的需求都是不一样的。通常来说,每天每公斤体重摄入0.8克至 1.6克不等。
碳水化合物
碳水化合物可分为简单的碳水化合物和复杂的碳水化合物。糖和葡萄糖是简单的碳水化合物,而淀粉和纤维是复杂的碳水化合物。现在,复杂的碳水化合物正在得到提倡,而简单的碳水化合物正在被抑制。世界各地正在使用糖税限制某些类别的软饮料产品。血糖指数用于度量摄入碳水化合物后,其转换成单糖速度。高血糖指数的食品通常不如低糖食品。例如,土豆、白面包和白米饭被认为是高血糖食物,而糙米和多谷物面包则被认为是低糖食物。
脂类
脂质包括脂肪和油。通常,在室温下,脂肪的流动性比油的要低。换句话说,脂肪更饱和,而油脂更不饱和。膳食建议是多摄入单不饱和或多不饱和油脂,而不是饱和脂肪。其中,最常见的是omega-6和omega-3脂肪酸对人体营养和生理功能所产生的影响。相关建议称omega-6和omega-3的比例需要在4:1左右才是健康的。然而,由于农业和农作物的进行,脂肪和油脂的膳食摄入量出现了利于omega-6类蛋白质的倾向,因此现在我们的比例趋于从20-30类下降至1类,因此这使得我们的身体更容易感染炎症。通过处理膳食中的脂质,我们要尝试将该比例回复到omega-6与omega-3的4:1比例。
还有一个问题是部分氢化大豆油(PHS)含有反式脂肪酸,已被证明其会导致冠心病。自从美国食品及药物管理局进行研究并报告对心脏健康的有害的因素以来,其耗费了30多年的时间,最终决定放弃使用PHS加工食品和食用油。相应地,现在市场上有更高级的油菜籽油,红花油,太阳花油和大豆油等更健康的植物油。当然,我知道你会问这些油是否是GMO(转基因生物)。 让我们暂时将这个话题留给时间吧。
所以,现在你已经对人类所需的宏观营养有了一些了解。 在下一个系列中,我们将探讨动物蛋白与植物蛋白的对比。
