In keeping with the Agricultural Advertising and marketing Useful resource Heart, Spanish missionaries introduced almonds to the New World, however the nut’s reputation didn’t rise till the 1900s. Right now, the US is the most important provider of almonds on this planet. California is the one state that produces almonds commercially. This may increasingly change, although, because the water provide in California declines.
Dietary profile
“Ounce for ounce, almonds are higher in fiber, calcium, vitamin E, riboflavin and niacin than any other tree nut,” Heap instructed Dwell Science. “Every one-ounce serving (about 23 almonds) provides 6 grams of protein and 4 grams of fiber, plus vitamin E , magnesium, riboflavin, calcium and potassium. In addition, almonds are a low-glycemic index food.”
Like different nuts, almonds include a reasonably excessive quantity of fats, with about 14 grams per one-ounce serving. Happily, about two-thirds of it’s heart-healthy monounsaturated fats, based on The George Mateljan Basis’s World’s Healthiest Meals web site.
A 2005 research revealed within the Journal of Vitamin confirmed that almonds pack the largest dietary punch if eaten entire, with their brown skins on (unblanched), reasonably than with their skins steamed off (blanched). The research recognized 20 highly effective antioxidant flavonoids in almond pores and skin.

A 2009 article in The American Journal of Scientific Vitamin (AJCN) regarded on the proof on nut consumption and a wide range of well being points. It famous that in 4 large-scale research thought-about main within the subject — the Iowa Girls’s Well being Research (1996), the Adventist Well being Research (1992), the Nurses’ Well being Research (1998) and the Physicians’ Well being Research(2002) — nut consumption was linked to a decrease threat for coronary heart illness. Collectively, the research confirmed a median discount within the threat of loss of life from coronary heart illness by 37 p.c, or “8.3 percent … for each weekly serving of nuts.”
“A growing body of evidence suggests that regularly choosing almonds in place of snacks high in refined carbohydrates is a simple dietary strategy to help support heart health,” mentioned Heap. In one other proof overview, revealed in 1999 in Present Atherosclerosis Experiences, researchers regarded on the Nurses’ Well being Research and estimated that consuming nuts as an alternative of an equal quantity of carbohydrates decreased coronary heart illness threat by 30 p.c. Substituting nuts for saturated fat, resembling these present in meat and dairy merchandise, resulted in a forty five p.c estimated decreased threat.
Changing almonds with saturated fat can also assist decrease LDL (dangerous) levels of cholesterol. A 1994 research revealed in The American Journal of Scientific Vitamin checked out males with regular levels of cholesterol and located that those that supplemented their diets with almonds for 3 weeks noticed a ten p.c discount in LDL ranges.
A 2017 research revealed in Journal of Vitamin checked out 82 individuals with excessive LDL ldl cholesterol. For six weeks, they ate a low-cholesterol weight loss program that included one-third of a cup of almonds or a muffin with the identical variety of energy. Then, individuals switched diets for an additional six weeks.

Many research have linked potassium with decrease blood stress as a result of it promotes vasodilation (widening of blood vessels), based on Right now’s Dietitian. The journal article cited a research of 12,000 adults, revealed in Archives of Inside Medication, which confirmed that those that consumed 4,069 mg of potassium every day lowered their threat of heart problems and ischemic coronary heart illness by 37 p.c and 49 p.c, respectively, in comparison with those that took 1,793 mg per day.
Magnesium can be important for coronary heart well being. In keeping with the College of Maryland Medical Heart, some docs have seen constructive outcomes from giving sufferers who’ve suffered from coronary heart failure doses of magnesium. There additionally could also be a hyperlink between decrease coronary heart illness threat in males and consumption of magnesium.
Heap famous that in 2003, the FDA permitted “a qualified health claim recognizing that California almonds may help reduce the risk of heart disease.” The official assertion mentioned:
“Scientific evidence suggests, but does not prove, that eating 1.5 ounces of most nuts, such as almonds, as part of a diet low in saturated fat and cholesterol may reduce the risk of heart disease. One serving of almonds (28g) has 13g of unsaturated fat and only 1g of saturated fat.”
Almonds could even be good for these affected by hyperlipidemia (extra lipids or lipoproteins within the blood). These sufferers was once instructed to avoid nuts due to their fats content material, however a research revealed in 2002 within the journal Circulation confirmed that hyperlipidemic sufferers who ate almonds as snacks really noticed vital reductions in coronary heart illness threat components.

A 2003 research revealed within the Worldwide Journal of Weight problems and Associated Metabolic Problems steered that combining almonds with a low-calorie, high-monounsaturated fats weight loss program led to extra weight reduction than did a low-calorie weight loss program with a lot of advanced carbohydrates. One other current research, revealed in 2015 within the Journal of the American Coronary heart Affiliation, checked out substituting almonds for a muffin of the identical caloric worth and located that although individuals didn’t shed extra pounds in both group, the almond-eating group noticed a discount in stomach fats, waist circumference and fats on the legs, in addition to improved LDL levels of cholesterol.

All forms of almonds, including almond flour, almond milk and almond butter, are excellent additions for those choosing a gluten-free lifestyle.”
Diabetes
In keeping with the AJCN overview of nuts and well being outcomes, the hyperlinks between nut consumption and diabetes threat and signs are much less clear than with coronary heart illness. Nonetheless, the Nurses’ Well being Research confirmed an inverse relationship between common consumption of nuts and diabetes, as did the Shanghai Girls’s Well being Research (2008).
Moreover, there may be some proof that almonds will be useful in regulating blood sugar ranges.

Researchers discovered that individuals’ blood sugar and insulin decreased after consuming the almond meal however not the others. Additionally, antioxidants within the blood elevated after the almond meal, whereas they decreased after the opposite meals.

A 2017 observational research of 826 sufferers with colon most cancers discovered that those that ate two or extra ounces of tree nuts, together with almonds, per week “had a 42 percent lower chance of cancer recurrence and 57 percent lower chance of death than those who did not eat nuts,” based on the research, which was revealed within the American Society of Scientific Oncology. The researchers don’t recommend changing chemotherapy with tree nuts. “Rather, patients with colon cancer should be optimistic, and they should eat a healthy diet, including tree nuts, which may not only keep them healthier, but may also further decrease the chances of the cancer coming back.”
